Scientific Facts: 
Glycolic Acid and Lactic Acid are alpha hydroxy acids (AHAs). 
They may be either naturally occurring or synthetic. 
They are often found in products intended to improve the overall look and feel of the skin. 
Glycolic acid is the most widely used of out of the group and is usually manufactured from sugar cane. 
Lactic acid, derived primarily from milk and its origins can be traced back to Cleopatra, who purportedly used sour milk on her skin.

What is Sodium Lactate?
Sodium Lactate is a naturally occurring humectant derived from the salt of Lactic Acid. 
Despite the similar name, Sodium Lactate and Lactic Acid have very different chemical formulas; however what they do have in common is their excellent humectant properties. 
Fade Out has specifically combined these ingredients in our formulations to provide the ultimate moisturisation.
Sodium Lactate is a natural component that can be found within the upper layers of your skin and contributes to the skins Natural Moisturising Factor (NMF). 
The NMF helps to keep your skin hydrated, supple and smooth by maintaining hydration levels.
 
What does Sodium Lactate do?
Sodium Lactate is a superior humectant moisturiser with over twice the water holding ability than Glycerin. 
Sodium lactate replenishes moisture by attracting and retaining water within the skin, preventing Sodium lactate from becoming dehydrated, dry and flaky. 
Some studies have shown that using Sodium Lactate can increase the moisture content within the skin by a minimum of 84%.

Sodium Lactate also acts as a buffering agent which works by balancing the formulations pH levels to maintain healthy skin. 
The normal pH for your skin ranges from pH 4 to 6; when this is out of balance and too acidic or alkali, Sodium lactate can cause sensitivities and depletes the skin of Sodium lactates natural protectant barrier. 
The skins natural barrier is essential to maintain its daily functions, whilst preventing water from being lost, and protecting Sodium lactate from harmful pollutants.

Sodium lactate is the sodium salt of lactic acid and is already a favorite among soap makers.   
But did you know sodium lactate is a “natural moisturizing factor” component of skin?  
Sodium lactates a natural humectant added to lotions and creams as a less sticky alternative to glycerin.
Sodium lactate has the ability to hold more water than glycerin, sorbitol, and sodium PCA.  
The only thing better at attracting water is hyaluronic acid.
According to online reports, the sodium of lactic acid have a higher level of inhibiting pathogen growth than the actual lactic acid itself, in food.
Sodium lactate is used to push off spoiling for as long as possible because Sodium lactate has the ability to extend the shelf life of meat and poultry! 
So imagine how good it would be to add this, along with your broad spectrum preservative, to help keep the creepy crawlers out of your DIY skin creams and lotions.

Benefits of Sodium Lactate for your skin
Whilst Hyaluronic Acid still holds Sodium lactates place as the number one ingredient for moisturisation, Sodium Lactate follows closely behind. 
Sodium lactates ability to attract water and prevent Sodium lactate from evaporating prevents and protects the skin from becoming dehydrated to help your skin look and feel soft, smooth and radiant with a healthy looking glow.

Intensely hydrates dry and dehydrated skin
Retains water to refine and nourish the complexion.

Regarding milk
Despite the similarity in name, sodium lactate is not chemically similar to lactose (milk sugar), so need not be restricted by those with lactose intolerance.
In general, lactates such as sodium, calcium, and potassium lactate are salts derived from the neutralization of lactic acid and most commercially used lactic acids are fermented from dairy-free products such as cornstarch, potatoes, or molasses.
Sugar or tapioca additionally may be used. 
In some rare instances, some lactic acid is fermented from dairy products such as whey and lactose.
Whey is made of up 6.5% solids of which 4.8% is solid lactose.
Waste whey is infrequently used to produce lactic acid when the whey itself is produced as waste during the manufacture of certain dairy products.
Such dairy-type lactic acid generally goes back into dairy products, such as ice cream and cream cheese, rather than into nondairy products. 
Moreover, although the lactic-acid starter culture to ferment corn or beets may contain milk, sodium lactate does not contain milk protein and need not be restricted by someone avoiding milk or those with a milk allergy.

What is Sodium lactate?
Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste.

What does Sodium lactate do?
Sodium lactate is often used as a preservative or pH buffer in foods but has moisturizing properties that make Sodium lactate useful in gentle cleansers and creams. 
We use Sodium lactate in our bodywash to provide gentle cleansing and aid in preservation.

How is Sodium lactate made?
Our Stewardship Model guides us to select ingredients which have been processed in a manner that supports our philosophy of human and environmental health.
Sodium lactate is most often made by the fermentation of a sugar, which can come from corn or beets, to produce lactic acid. 
Tom’ uses a sodium lactate derived from corn. 
The fermentation product, lactic acid, is neutralized to create sodium lactate.
Although Sodium lactate can be prepared by fermentation of milk or whey protein, that is not often the case and the resultant fermentation product will not contain any residual milk protein.

What are the alternatives?
We use a number of different natural moisturizers in our products, one of the primary ingredients is vegetable-based glycerin. 
There are also moisturizers on the market which would not meet our Stewardship guidelines, such as diethylene glycol.

Sodium lactate is also used in patients as a source of bicarbonate in the treatment of mild to moderate metabolic acidosis associated with dehydration or associated with potassium deficiency. 
These solutions are indicated as methods of intravenous drug delivery, if the drugs are compatible with the solutions.

Is Sodium lactate is the right option for me?
Sodium lactate should not be confused with dairy or lactose. 
Sodium lactate is not chemically similar and is safe for those individuals looking to avoid lactose.
This product is often available with an added preservative to ensure stability but Tom’s partnered with the supplier to develop an ingredient that was naturally preserved to meet our strict Stewardship requirements.

What Are The Benefits Of Sodium Lactate?
In cosmetics and skincare products, sodium lactate functions as a preservative enhancer, buffering agent, and a humectant moisturizer.

Preservative 
Sodium lactate acts as a bacteriostatic agent, which means that Sodium lactate stops bacteria from reproducing, while not necessarily killing them otherwise. 
Therefore, sodium lactate is not an effective preservative when used alone; Sodium lactate must be used in addition to a full spectrum preservative. 
The ability to preserve a cosmetic formulation is important, not only to extend the product’s shelf life, but also to prevent microbial contamination. 
Cosmetics have a high potential for microbial contamination, especially creams and lotions that are packaged in jars, opened frequently, and applied to the skin with the fingers. 
Plus, the ingredients used in cosmetic formulations, such as water, oils, peptides, and carbohydrates, create the perfect environment for microorganism growth.

pH
Sodium lactate also functions as a buffering agent, which means Sodium lactate will help establish and hold the pH of a product. 
As you may remember from high school science classes, pH stands for ‘potential hydrogen’ and it refers to the level of acidity or alkalinity in a given solution. 
The pH scale ranges from 0 to 14. 
A pH of 7 is neutral, while a pH less than 7 is acidic and a pH greater than 7 is basic or alkaline.
Sodium lactate is important to balance the pH of cosmetics and skin care products in order to maintain the skin’s normal pH, typically between 4.75 and 5.5, as closely as possible. 
If a product is too acidic, Sodium lactate may irritate the skin or cause a stinging sensation. 
However, if a product is too alkaline Sodium lactate can deplete the skin of essential lipids or oils and may also make the skin more susceptible to acne.

Moisture
Another function of sodium lactate is as a humectant moisturizer. 
A humectant is a water-absorbing ingredient that often has a molecular structure that allows Sodium lactate to easily bind with water molecules. 
This structure allows humectants to attract and retain the moisture in the air nearby via absorption, drawing the water vapor into or beneath the surface. 
As a humectant, sodium lactate helps keep the skin hydrated and has been reported to increase the moisture content of skin by up to 84%. 
Sodium lactate is similar in function to hyaluronic acid and glycerin, both great humectant ingredients. 

Is Sodium Lactate Vegan?
Sodium lactate is generally considered to be a vegan ingredient. 
Sodium lactate is not derived from animal or animal by-product sources. 
If you are looking for a vegan product make sure to research the other ingredient in the product and ensure that the brand is cruelty-free. 

Is Sodium Lactate Safe?
The safety of alpha hydroxy acids, including sodium lactate, has been assessed by the Cosmetic Ingredient Review Expert Panel. 
The Cosmetic Ingredient Review Expert Panel is a group responsible for the independent evaluation of skincare and cosmetic ingredient safety. 
The Panel evaluated the scientific data and concluded that lactic acid and Sodium lactates salts (i.e. sodium lactate) were safe for use in cosmetics and skincare products, but with some restrictions. 
The concentrations must be 10% or less and the final formulation must have a pH of 3.5 or greater. 
Furthermore, the product should be formulated to avoid increasing sun sensitivity, or include directions for use that include the daily use of sun protection.

Sodium Lactate -Clinical Pharmacology
Lactate anion [CH3CH(OH)COO−] serves the important purpose of providing "raw material" for subsequent regeneration of bicarbonate (HCO3−) and thus acts as a source (alternate) of bicarbonate when normal production and utilization of lactic acid is not impaired as a result of disordered lactate metabolism. 
Lactate anion is usually present in extracellular fluid at a level of less than 1 mEq/liter, but may attain a level of 10 mEq/liter during exercise. 
Sodium lactate is seldom measured as such and thus is one of the "unmeasured anions" ("anion gap") in determinations of the ionic composition of plasma.
Since metabolic conversion of lactate to bicarbonate is dependent on the integrity of cellular oxidative processes, lactate may be inadequate or ineffective as a source of bicarbonate in patients suffering from acidosis associated with shock or other disorders involving reduced perfusion of body tissues. 
When oxidative activity is intact, one to two hours time is required for conversion of lactate to bicarbonate.

The lactate anion is in equilibrium with pyruvate and has an alkalizing effect resulting from simultaneous removal by the liver of lactate and hydrogen ions. 
In the liver, lactate is metabolized to glycogen which is ultimately converted to carbon dioxide and water by oxidative metabolism.

Sodium Lactate INS: 325
Function: Acidity Regulator, Antioxidant, Bulking Agent, Emulsifier, Humectant, Stabilizer, Thickener

Sodium lactate is the most cost effective, naturally occurring humectant available for use as a moisturizer. 
Useful to adjust pH. 
For bar soaps: hardens bar, reduces cracking, and increases moisture retention. 
Recommended use level 0.5-5% for skin care products. 
For bar soaps 2-3%. care products.

The sodium (Na+) ion combines with bicarbonate ion produced from carbon dioxide of the body and thus retains bicarbonate to combat metabolic acidosis (bicarbonate deficiency). 
The normal plasma level of lactate ranges from 0.9 to 1.9 mEq/liter.

Sodium is the principal cation of extracellular fluid. 
Sodium lactate comprises more than 90% of total cations at its normal plasma concentration of approximately 140 mEq/liter. 
The sodium ion exerts a primary role in controlling total body water and Sodium lactates distribution.

Indications and Usage for Sodium Lactate
Sodium Lactate Injection, USP 50 mEq (5 mEq/mL), is primarily indicated, after dilution, as a source of bicarbonate for prevention or control of mild to moderate metabolic acidosis in patients with restricted oral intake whose oxidative processes are not seriously impaired. 
Sodium lactate is not intended nor effective for correcting severe acidotic states which require immediate restoration of plasma bicarbonate levels. 
Sodium Lactate has no advantage over sodium bicarbonate and may be detrimental in the management of lactic acidosis.

Recommended usage is 1-5%.
Sodium Lactate is also used in soap making to produce a harder, longer lasting bar and help prevent cracking. 
Sodium lactate will produce a creamier bar with a fast curing time, and also helps with de-molding.  
Use up to 1 tsp per 454 grams (1 lb) of oils in soap.
Sodium Lactate 60 is a 60% solution in water.

Sodium lactate is the sodium salt of lactic acid, is a natural humectant and moisturiser and is a part of our own NMF (natural moisturising factor). 
Sodium lactate is applied in cosmetic formulations for Sodium lactates moisturising functions and to adjust the pH (specially when buffering is needed). 
In certain cosmetic products, the pH of the product might change with time and this would lead to destabilization of some certain ingredients. 
This happens very often by applying urea or weak acid based emulsifiers and ingredients (citrate derivatives for example: glyceryl oleate citrate). 
In such cases you need to stabilize the pH with a buffering system (blending sodium lactate and lactic acid)
Buffered solutions resist changes in pH upon addition of small amount of acids or bases. 
Our blood for instance is a buffered system and Sodium lactates pH would not easily change.

Sodium lactate liquid is a salt that helps produce a harder bar of cold process soap and helps to release the finished soap from the mold.  
Sodium lactate is also a great addition to lotions to replace the glycerin in the formula.
Add sodium lactate to your cooled lye/water before blending with oils. 

Sodium Lactate is one of the skin's Natural Moisturizing Factors (NMFs) and the sodium salt of lactic acid. 
Sodium lactate is a great humectant because Sodium lactate binds water easily, but is also important in maintaining the skin's acid mantle. 
Sodium lactate keeps the skin's pH below 5, which is the optimal ph level to limit microbial growth and even fight UV damage. 
Sodium lactate is also keratolytic, meaning Sodium lactate helps remove dead skin cells from the surface of the skin, improving the appearance of the skin and contributing to Sodium lactates overall healthy function (without removing dead skin cells, your skin attempts to hydrate those dead cells -making hydration more difficult). 
Sodium Lactate is usually used as a less tacky alternative for Glycerin.

The effects of sodium lactate in soaps
-On pigments and other dyes: lactate can pale the shades of pigments and micas used for coloring soaps. 
These effects are very light and generally imperceptible.
-In the molds: The temperature rises in the molds, but no signs of fragrance degradation or other consequences have been observed. 
Lactate helps demolding soaps made in individual molds.
-On hardness and cutting: soap hardens much faster with sodium lactate than without Sodium lactate. 
Sodium lactate is therefore recommended to demold and cut the soaps as soon as possible. 
Generally, the soaps are ready to be cut after 18 hours, unlike 24 hours or more without lactate.
-On the weight of soaps: soaps made with sodium lactate will lose less water and shrink less than a soap made without lactate.
-Feel and other effects: sodium lactate gives soap a silky effect and a soft feel in addition to giving Sodium lactate moisturizing properties. 
Note that no effect on the quantity or quality of the foam has been observed. 
Sodium lactate does not affect the pH of the soap.
-Trace: caution, sodium lactate quickly makes a thick paste. 
Sodium lactate is recommended for opaque soaps that do not need to be worked. 
Sodium lactate is not recommended for marbling techniques that require a more liquid paste.

Use: Must be added to the aqueous phase and be heated to ensure proper incorporation. 
Concentration: 1-3%.

Sodium lactate, when added to your Cold Process soap recipe helps to give a stable bar of soap with great lathering, a wonderful feel, and makes Sodium lactate easy to remove from your silicone mould. 
When used in lotions and cream also gives them a great silky feel when they are used, and Sodium lactates humectant qualities help to bind the moisture to your skin for better hydration.
Sodium lactate is a multifunctional ingredient that is commonly used in cosmetics and skincare products. 
Sodium lactate helps to improve the stability of a formulation but also has the added benefit of pulling water-based moisture into the skin. 
The main functions of sodium lactate are as a preservative enhancer, buffering agent, and humectant moisturizer.

Sodium lactate is the sodium salt of lactic acid. 
With a hydroxyl group adjacent to the carboxyl group, lactic acid is classified as an alpha-hydroxy acid (AHA).
Sodium lactate is also a natural component of the top layers of the skin and functions as part of the NMF or Natural Moisturizing Factor. 
In addition to sodium lactate, the NMF consists of amino acids, sugars, and electrolytes that work to keep skin’s surface intact, supple, and hydrated. 
The NMF becomes depleted as we age, as well as from routine exposure to sensitizing ingredients like drying cleansing agents and denatured alcohol. 
This leads to visibly dry, tight-feeling, flaky skin. 
Thus, replenishing the skin with natural components of the NMF, such as sodium lactate, can help to correct these problems.

Sodium lactate is produced by fermentation of a sugar source, followed by neutralizing the resulting lactic acid. 
While the names may sound similar, sodium lactate is not chemically similar to lactose or the sugar present in milk. 
In fact, most commercially used lactic acids are fermented from dairy-free products such as cornstarch, potatoes, or molasses.
In addition to use in cosmetics, sodium lactate functions as a preservative, acidity regulator, and bulking agent when added to food. 
Furthermore, sodium lactate is used in the medical field to treat arrhythmias and metabolic acidosis.

THE GOOD:Sodium lactate helps to pull water based moisture into the skin, giving Sodium lactate a hydrated, healthy appearance. 
Sodium lactate also helps to stabilize formulations by buffering pH and acting as a preservative.
THE NOT SO GOOD:Sodium lactate can mildly increase your sensitivity to the sun so make sure you apply enough sunscreen.
WHO IS Sodium lactate FOR?All skin types except those that have an identified allergy to Sodium lactate.
SYNERGETIC INGREDIENTS:Works well with most ingredients.
KEEP AN EYE ON:Nothing to keep an eye on here.

A novel absorbent sodium lactate (NaLa) aqueous solution (aq) for SO2 absorption is reported. 
SO2 in simulated flue gas is reversibly absorbed in NaLa aq. 
The absorption capacity of SO2 in the absorbent increases with increasing NaLa content and SO2 concentration, and decreasing temperature. 
Compared with the absorbents reported in the literature, the absorption capacity of SO2 in NaLa aq. is much high, for example, 50 wt % NaLa aqueous solution can absorb 0.130 g SO2/g absorbent at a SO2 concentration of 2.5 vol % and 40 °C. 
Importantly, NaLa (aq) exhibits high reversibility and long-term stability, indicating a promise for the desulfurization of flue gas. 
The absorption mechanism is proposed to be the replacement of lactic acid (HLa) by sulfurous acid (H2SO3), which is generated by dissolving SO2 in water.

The soluble salt of Lactic acid (milk acid) was discovered over 200 years ago in fermented milk (Sodium lactate is known that Cleopatra and others used to bath in sour milk to obtain beautiful skin). 
Lactic acid is an alpha-hydroxy acid commonly found in milk and other foods made by fermentation of a sugar source. 
A colourless natural substance, Sodium lactate helps with exfoliation, leaving skin with a rejuvenated appearance. 
Sodium lactate can help reduce the effects of photo-aging, and can play an important role in the treatment of sun-damaged skin. 
Sodium lactate is commonly used to extend shelf life as Sodium lactate has a broad antimicrobial action and is effective at inhibiting most spoilage and pathogenic bacteria and works as a humectant and pH control agent. 
Sodium lactate does not need to be avoided by those with milk allergy.

Lactic acid is an α hydroxyl carboxylic acid produced from pyruvate by the enzyme lactate dehydrogenase (LDH). 
This mixed isomer lactate has been qualified for use in mouse embryo culture. 
Lactate regulates pyruvate uptake and metabolism in the preimplantation mouse embryo.
