Polysorbate 60 dissolves well in water, ethanol, benzene and its homologues. 
Polysorbate 60 has the ability to create an O/W emulsion (oil in water).


Polysorbate 60 or Tween 60, the full name polyoxyethylene (20) sorbitan monostearate, is an ingredient made from sorbitol, stearic acid (C18) and ethylene oxide. 
Polysorbate 60 is primarily used as an emulsifier in food (the European food additive number E435) and a solubilizer & surfactant in cosmetics.


Polysorbate 60 is emulsifier for pharmaceuticals and cosmetics, Stabilizer for color materials, Stabilizer for emulsion polymerizations, Emulsifier for adjuvant of agrochemicals, Emulsifier for water based metal process cutting oils, Surface coating type antistatic agents.

Polysorbate 60  is an oil-in-water emulsifier. Polysorbate 60  also acts as a spreading aid for bath oils, adds water-dispersibility to anhydrous systems and is a solubilizer for oils and fragrances.
Polysorbate 60 is used as a emulsifier for cosmetics and pharmaceuticals, dispersant for insecticides, herbicides, cattle dyes, penetrant, levelling agent, lubricant, antistat.


Polysorbate 60 is a common little helper ingredient that helps water and oil to mix together, aka emulsifier.


Polysorbate 60 is a synthetic ingredient that is used in cosmetics and skincare to improve the texture and sensory feel of formulations. It is used in products as a surfactant, emulsifier, and solubilizer.

Polysorbate 60 is produced by the ethoxylation of sorbitan. Sorbitan is the dehydrated form of sorbitol, a sugar alcohol that can naturally be found in some fruits. Ethoxylation is a chemical reaction in which ethylene oxide is added to a substrate, in this case, sorbitan. Sorbitan is reacted with 60 units of ethylene oxide, hence the 60 in the ingredient name. The final step is the reaction with fatty acids obtained from vegetable fats and oils, such as lauric acid, palmitic acid, stearic acid, or oleic acid. In addition to its function in cosmetics, polysorbate 60 can be used to prepare a wide variety of products in the food and pharmaceutical industries.

Polysorbate 60 is used to improve the texture and feel of products. 

Solubilizer
Polysorbate 60 is a solubilizer that helps other ingredients to dissolve in a solvent in which they would not normally dissolve. 
Specifically, polysorbate 60 helps to disperse oil in water as opposed to water in oil. Polysorbate 60 is an excellent solubilizer for essential oils.


Polysorbate 60 is an orangish colored oily viscous liquid at room temperature. It will be a semisolid at lower temperatures.  
Polysorbate has an HLB (hydrophilic/lipophilic balance) of 14.9.  It is slightly more lipophilic than polysorbate 20 and 40 due to the longer length of stearic acid.


Polysorbate 60 is soluble in water due to its high HLB ratio and not soluble in oils. Polysorbate 60 easily blends into water.


Polysorbate 60 is commonly used in flavors and other food products as well as cosmetics and personal care items. 
Polysorbate 60 is an excellent choice to blend fat-based flavor components into a water-based emulsion type flavor.   
Due to its very high HLB ratio, Polysorbate 60 helps water and oil-based ingredients blend and to prevent their separation.  

Polysorbate 60  can also be used with low HLB ratio emulsifiers to assist with both oil in water and water in oil emulsions. 
Applications that require foaming, aeration, and blending of oils into water-based products are where polysorbate 60 excels.  
Polysorbate 60 works great in cake batters to assist in aeration and also breads to create a silky smooth crumb.  
Polysorbate 60 is also commonly used in cake or buttercream type icings to assist with aeration and to help prevent water separation.


Chemical Properties
Polysorbate 60 has a faint, characteristic odor and a warm, somewhat bitter taste. It is a mixture of stearate and palmitate partial esters of sorbitol and sorbitol anhydrides condensed with approximately 20 mole of ethylene oxide (C2H4O) for each mole of sorbitol and its mono- and dianhydrides.

What is Polysorbate 60 (E435) in Food ?


Polysorbate 60 or Tween 60, the full name polyoxyethylene (20) sorbitan monostearate, is an ingredient made from sorbitol, stearic acid (C18) and ethylene oxide. 

Polysorbate 60 is primarily used as an emulsifier in food (the European food additive number E435) and a solubilizer & surfactant in cosmetics.


Like other polysorbates, the number 60 after polysorbate means the type of fatty acid, here is monostearate; the number 20 following polyoxyethylene indicates the total number of oxyethylene groups in the molecule structure.

How is it made?
According to the FDA, polysorbate 60 is manufactured by reacting stearic acid with sorbitol to obtain sorbitan monostearate first and then condensed with ethylene oxide. (1)

What is it made of?
As the commercial food grade stearic acid usually contains palmitic acid, so polysorbate 60 is a mixture of ethoxylated ethers of stearic and palmitic acid esters of sorbitol and its mono- and dianhydrides and other related compounds. 


Polysorbate 60 is the common name for polyoxyethylene sorbitan monostearate, it is a hydrophilic (water-loving) surfactant.  
Polysorbate 60 is made by reacting stearic acid with sorbitol and then ethylene oxide.  
Polysorbate 60 is a common food grade emulsifier used as a solubilizer and surfactant.

 
Use: Hydrophilic emulsifier; solubilizer; dispersant; water soluble; plant-derived

Polysorbate 60 is a highly hydrophilic surfactant and approved as a food additives. Polysorbate 60 is a usuful emulsifier, dispersant and solubilizer for aroma chemicals and oils. 

    
Tween 60 
Polyoxyethylene (20) sorbitan monostearate (IUPAC)
E 435 
Molecular formula: C 64 H 126 O 26 
Brief description: dark yellow, viscous liquid 

Tween 60 is oil/water type emulsifier. It is soluble in 40℃ water, organic solvents, and insoluble in oil. HLB value: 14.9.

Tween 60 is used as emulsifier in food, medicine, plastic and cosmetics. Tween 60 is also used as softener for fiber processing.


Properties 
The derivative of sorbitol as a complex compound with fatty acids (mainly stearic acid 50) and ethylene oxide is produced in a multi-stage process from usually vegetable fats. 
Polysorbate 60 has an HLB value of 14.9 and is therefore suitable for the production of oil-in-water emulsions. 
The emulsifying effect is strong and independent of acidity and temperature.

Usage 
Polysorbate 60 is approved in the EU as a food additive with the number E 435 for certain foods in quantities of up to five, in shortening also up to ten grams per kilogram and in food supplements without maximum quantity restrictions ( quantum satis ). 
The permitted daily dose is 10 milligrams per kilogram of body weight for all polysorbates combined. 
It acts as an emulsifier, foaming agent and complexing agent.

Why Is Polysorbate Used In Skincare?
In cosmetics and skincare products, polysorbate 60 functions as a surfactant, emulsifier, and solubilizer.

Surfactant
As a surfactant, polysorbate 60 works by lowering the surface tension between two substances, such as two liquids or a liquid and a solid. A surfactant molecule contains one end that is hydrophilic or attracted to water and one end that is lipophilic or attracted to oil. This allows surfactants to attract and suspends oils, dirt, and other impurities that have accumulated on the skin and wash them away. Due to these properties, polysorbate 60 can be found in many different cleansers, shampoos, and body washes.

Emulsifier
As an emulsifier, polysorbate 60 is often used in formulations that contain both water and oil components. Mixing water and oil-based ingredients can be difficult as they will often separate and split. To address this problem, an emulsifier like polysorbate 60 can be added to improve the consistency of a product, which enables an even distribution of topical skincare benefits.

Solubilizer
A solubilizer helps other ingredients to dissolve in a solvent in which they would not normally dissolve. Specifically, polysorbate 60 helps to disperse oil in water as opposed to water in oil. Polysorbate 60 is an excellent solubilizer for essential oils.

Is Polysorbate 60 Safe?
The United States Food and Drug Administration (FDA) allows polysorbate 60 to be directly added to food as a flavoring agent or as a multipurpose additive. The safety of polysorbate 60 has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel, a group responsible for evaluating the safety of skincare and cosmetic ingredients. The Expert Panel evaluated the scientific data and concluded that polysorbate 60 was safe as used in cosmetics and personal care products.

Despite the approval of polysorbate 60 by the CIR Expert Panel, there are concerns about the presence of ethylene oxide in this ingredient. This is because the process of ethoxylation may lead to contamination with 1,4-dioxane, a potentially dangerous by-product. 1,4-dioxane is a known animal carcinogen that penetrates readily into the skin. According to the National Toxicology Program, ‘1,4-dioxane is reasonably anticipated to be a human carcinogen.’ It has also been linked with skin allergies. However, the potential presence of 1,4-dioxane can be controlled through purification steps to remove it before blending polysorbate 60 into cosmetic formulations.


Polysorbates are metabolized like fatty acids in the human organism and are biodegraded in nature like natural fat.

What Is It?
Polysorbate 20 and the other Polysorbate ingredients (Polysorbate 21, Polysorbate 40, Polysorbate 60, Polysorbate 61, Polysorbate 65, Polysorbate 65, Polysorbate 80, Polysorbate 81, Polysorbate 85) are a series of general purpose hydrophilic, nonionic surfactants. The Polysorbates are used in a variety of products including skin fresheners, skin care products, skin cleansing products, makeup bases and foundations, shampoos, permanent waves and fragrance powders.

Why is it used in cosmetics and personal care products?
The Polysorbate ingredients help other ingredients to dissolve in a solvent in which they would not normally dissolve. They also help to form emulsions by reducing the surface tension of the substances to be emulsified.

Scientific Facts: 
Polysorbates are surfactants that are produced by reacting the polyol, sorbitol, with ethylene oxide. The number in the name of the Polysorbate indicates the average number of moles of ethylene oxide that has been reacted per mole of sorbitol. The polyoxyethylenated sorbitan is then reacted with fatty acids obtained from vegetable fats and oils such as lauric acid, palmitic acid, stearic acid and oleic acid. Polysorbates function to disperse oil in water as opposed to water in oil

Hydrophile-Lipophile Balance (HLB)
14.9, gives oil-in-water emulsions, O/W.

It is more lipophilic than polysorbate 20 and 40 due to the long length of the fatty acids – stearic acid, compared with other fatty acids, lauric acid (C14) and palmitic acid (C16) that linked to the polyoxyethylene sorbitan part of the molecule, respectively.

Solubility
Soluble in water, insoluble in mineral oil and vegetable oils.
Soluble in ethyl acetate and toluene. 
What’re the Uses of Polysorbate 60?
Polysorbate 60 is a synthetic multi-ingredient that can be used as a surfactant, emulsifier, solubilizer, stabilizer in food, cosmetics and personal care products.

Food
Polysorbate 60 helps water-based and oil-based ingredients blend easily and prevent their separation in food. Polysorbate 60 and 80 are mostly used in food among the category of polysorbates, but the latter is used more than 60 in food. 

As a high HLB emulsifier, its food grade can be blended with a low HLB emulsifier (e.g. sorbitan stearate, mono and diglycerides) to provide a suitable HLB value for the various food uses, either oil in water, or water in oil emulsion.

Cosmetics
Its general purpose in cosmetics is to mix water and oil together. Polysorbate 60 functions as a surfactant, emulsifier, solubilizer and dispersing agent.

Some of its applications as follows:

Polysorbates are an emulsifier and food additive that comes from a reaction of sorbitan fatty acid with ethylene oxide. The name includes a range of polysorbates, such as 20, 60, 65 and 80. However, Polysorbates 60 and 80 are the most commonly used in food production. They are used in baked goods and frozen desserts to help with:

Extended shelf life
Improved crumb color and strength
Increased volume1
How do Polysorbates Work?
Polysorbates are very surface active, with a HLB value ranging from 14 to 16. They cause similar reactions as monoglycerides and diglycerides, but smaller quantities are used to produce the same results. Polysorbates are created by reacting stearic acid, sorbitol and ethylene oxide. They create a nonionic surfactant, with hydrophilic and hydrophobic ends. So it allows water and oil to mix, and gives oil-in-water emulsions. It can be combined with other HLB emulsifiers to create stable products, and works best with fatty alcohols.

Types of Polysorbates
The most common types of polysorbates are 20, 40, 60, 65, and 80, with the number representing the fatty acid associated with the polyoxyethylene sorbitan component of the molecule. The fatty acids are lauric (C14), palmitic (C16), stearic (C18:0), and oleic (C18:1). The lower numbers are more hydrophilic, while higher ones have higher lipophilic properties.

Application
Polysorbates are sold as a waxy, yellow paste that mixes easily. They are found in shortening, margarine, peanut butter, dry mixes, ice cream, dairy products, and baked goods.

Polysorbate 60 can be an effective dough conditioning agent at a level as low as 0.2 percent based on flour weight.2 Even better results can be reached if mono and diglycerides are used along with Polysorbate 60. 
To be soluble in water, it must be at 25 oC or 77oF.2

FDA Regulations
Polysorbates 60, 80, and 85 are allowed as a direct food additive in the United States, under clearly restricted levels and applications. 
While they are used around the world, some countries in the Middle East and Japan have not approved polysorbates.

As a food additive, Polysorbates 60 and 80 must have an acid number between 0 to 2. 
There are different regulations on the amounts to be used as an emulsifier and coating agent or combined with other emulsifiers for polysorbate 60 and limitations on polysorbate 80 as a solubilizing, dispersing, and emulsifying agent, so be sure to check the full FDA stipulations.

Processing at room temperature to save time and energy
Besides the well known emulsifying process with two hot phases there is also the possibility to formulate an emulsion with a processing temperature at room temperature. 
The processing of O/W emulsions at room temperature has several significant benefits. 
For example, it is no longer necessary to heat the water and oil phase to 70-80 °C. 
This saves considerable amounts of energy and reduces the production time as the cooling step is eliminated. 
Another very important advantage is that head-sensitive APIs can be added to the emulsion at any point. 
Kolliphor PS 60 is very suitable for this kind of application.

The MONTANOX range is composed of different grades of polysorbates that can be used to solubilize active pharmaceutical and/or biological ingredients and to formulate oil-in-water emulsions for oral, topical and injectable products.

The triple action of polysorbates
MONTANOX products are polyethoxylated sorbitan esters.
These hydrophilic surfactants play a triple role: They are used as emulsifiers to formulate oil in water emulsions but also as solubilizers for active ingredients with low solubility and also as antiaggregants for biological active ingredients.
MONTANOX products are stable in acidic or basic media and in the presence of electrolytes and are compatible with other surfactants.
They can be combined with MONTANE to produce highly stable emulsions.

A suitable grade for every application
The MONTANOX range is composed of monoesters of lauric, stearate or oleic fatty acids. 
They each have a degree of ethoxylation of 20 and are characterized by their HLB (Hydrophilic-Lipophilic Balance).
There are two pharmaceutical grades: PPI and PHA PREMIUM.

The PPI grade is designed for injectable administration and products are manufactured according to the Good Manufacturing Practices “GMP part II” and comply with the EP, USP and JP or JPE pharmacopoeia.
The PHA PREMIUM grade is designed for oral and topical administration and products are manufactured according to IPEC’s GMPs and comply with the EP and USP pharmacopoeia.
