PEG-100 is a surfactant used in household chemicals, ceramic, paper, cosmetic and metal industries.
In products, PEG-100 acts as a plasticiser, anti-adhesive, binding substance and moisturising substance.
You can find PEG-100 in products such as cosmetics, food packaging, detergents or additives for the processing of plastics.
PEG-100 is a multitasking ingredient that can be used as an emulsifier/cleansing agent in cosmetic formulations.
PEG-100 gives a soft and moist feeling to the skin.
PEG-100 contributes to foam formation in cleaning products.
PEG or polyethylene glycol stearate is an ingredient that is used in skincare and body care products.
PEG-100 is a soft waxy substance used in moisturizers, conditioners, shampoos, cleansers, and soap-free detergents.
The 100 in PEG-100 refers to the number of ethylene oxide monomers present on the molecule.
PEG-100 is mainly utilized in your skincare products due to PEG-100 emulsifying abilities.
Emulsifiers help to mix oil and water-based ingredients so that they produce a smooth, stable texture.
This emulsifying characteristic of PEG-100 also helps to lift oil and dirt from the skin so that PEG-100 can be rinsed away, making PEG-100 a staple addition to cleansers and body washes.
Characteristics of PEG-100:
PEG-100 is an INCI name for a compound whose chemical name is polyoxyethylene glycol.
The CAS number of the compound is 25322-68-3.
PEG-100 is used in diverse applications, where PEG-100 mostly acts as an emulsifier and wetting agent.
PEG-100 is a white to light yellow agent with a faint yet characteristic odour.
Similarly to other compounds that belong to the broad PEG group, this surfactant dissolves very well in water.
PEG-100 is also soluble in organic liquids such as methanol, ethanol, chloroform or ethylene glycol.
The molar mass of PEG-100 is approx. 4500 g/mol.
PH of a 10% aqueous solution ranges from 4.6 to 7.4.
The hydroxyl number for PEG-100 is 23 to 28 mg KOH/g.
PEG-100 density at 70oC is approximately 1.08 g/ml.
Molecules of PEG-100 ignite and decompose above the temperature of 220oC.
PEG-100 is safe, non-toxic and does not cause irritation.
Advantages of PEG-100:
Major advantages are as follows:
Unique softening, lubricating and moisturising properties,
Biodegradability,
A wide range of applications,
A convenient physical form that facilitates handling under industrial conditions,
Unlimited water solubility,
Non-toxicity.
PEG-100 is a soft waxy substance used in moisturizers, conditioners, shampoos, cleansers, and soap-free detergents.

Applications of PEG-100:
Effects of PEG-100 In Cosmetics and Industrial Applications:
As a surfactant, PEG-100 is used in the cosmetic industry.
PEG-100 unlimited water solubility is employed in the design of what are known as hard cosmetics e.g. lipsticks.
PEG-100 is used as their ingredient.
When used as a humectant in cosmetic products, PEG-100 also retains water.
You can find PEG-100 in products such as creams, face wash preparations, scrubs or make-up removers.
PEG-100 is also used to increase the viscosity of a cosmetic formulation (improving PEG-100 performance and application properties), i.e. modify PEG-100 rheology.
PEG-100 is used in household chemicals.
PEG-100 is a popular additive for detergents such as dishwasher or laundry tablets.
PEG-100 is used as a binding agent and a carrier of active substances.
Besides cosmetics and detergents, PEG-100 is a popular surfactant used in metalworking processes.
As an ingredient of lubricants, primarily water-soluble synthetic machining fluids and heat transfer fluids.
The use of machining fluids that contain PEG-100 helps carry away the heat produced during the processing of metal pieces.
For the plastics industry, PEG-100 is an anti-adhesive agent used in rubber and elastomer processing.
Anti-adhesive agents on the surface of materials reduce their adherence to the mould and thus facilitate the removal of rubber or plastic casts.
Compounds such as PEG-100 are essential for the rubber industry processing, as they boost processes and increase their efficiency.
PEG-100 has a positive opinion of an international organisation, i.e. the FDA (Food and Drug Administration).
The FDA has approved the use of the surfactant as an indirect food additive.
PEG-100 is used in the production of food packaging based on biopolymers.
PEG-100 needs to be used as recommended and the maximum allowable dose may not be exceeded.
Uses of PEG-100:
PEG-100 is used in the production of food packaging based on biopolymers.
PEG-100 is used as a binding agent and a carrier of active substances.

PEG-100 is used as their ingredient.
Regions where it is used of PEG-100:
As a Emulsifier:
PEG-100 is included in skincare and beauty products for a variety of reasons, ranging from making the skin softer to helping product formulations better keep their original consistency.
As an emollient, PEG-100 is included within skincare product formulations to give the skin a softer feel.
PEG-100 achieves this through strengthening the skin’s moisture barrier by forming a thin fatty layer on the skin’s surface, which prevents moisture loss and increases overall hydration.
This moisturizing effect increases the hydration of skin cells, which in turn makes the skin softer and boosts skin health.
Texture:
Another use for PEG-100 has to do with PEG-100 emulsification properties.
Emulsifiers are valued in the skincare and personal care industries because of their ability to mix water and oils.
Without this ability, the oils in many formulations would begin to separate from the water molecules, thus undermining product texture and consistency.
PEG-100 stearate is also used to help to cleanse through mixing oil and dirt so that PEG-100 can be rinsed away.
As a Surfactant:
Lastly, PEG-100 can also act as a surfactant, when used in body and facial cleansers.
Surfactants disrupt surface tension, helping to mix water and oil.
This characteristic helps the ingredient cleanse the skin by mixing oil with water, lifting dirt trapped inside the skin’s oils, and rinsing PEG-100 away from the skin.
PEG-100 is Safe?
PEGs are a class of ingredients that have been involved in controversy over their use, particularly from the clean or green beauty industry.
This controversy is in part due to claims that PEG-100 is linked to toxicity within the body due to the presence of impurities during the manufacturing process.
This toxicity claim has been evaluated by both the US Food and Drug Administration (FDA) and the Cosmetic Ingredient Review Expert Panel, both of these groups are responsible for evaluation and regulation of skincare ingredients in the US.
Through their research, they determined PEG compounds safe for their indicated uses in skincare and personal care products.
In 2002 the Cosmetic Ingredient Review Expert Panel reviewed newly available data and reaffirmed the approval.
However, if you are concerned, discuss PEG-100 with a doctor or dermatologist, who can advise you whether your medical history may place you at risk with this ingredient.
