POLYSORBATE 80


Polysorbate 80 (INCI: polyoxyethylene (20), sorbitan monooleate) is an amber/golden-colored viscous liquid used as as an emulsifier or surfactant in foods, medicines, skincare products, vaccines etc. It also acts as a surfactant in soaps and cosmetics.

Also known as tween 80, polysorbates are a class of emulsifiers used in pharmaceuticals and food preparation. They are often used in cosmetics to solubilise essential oils and fragrance oils into water-based products.

Emulsifier, dispersant, solubilizer, lubricant, detergent, antistat, wetting agent for cosmetics & pharmaceuticals, polishes, insecticides, leather degreasing and veterinary products.
A non-ionic, hydrophilic emulsifier, co-emulsifier and solubilizer for pharmaceutical preparations like emulsions and creams, gels and foams as well as softgels.

Polysorbates are non-ionic surfactants and emulsifiers derived from polyethoxylated sorbitan and stearic or oleic acid. 
Polysorbates are mainly used as a solubilizer, emulsifier or suspension stabilizer for pharmaceutical application. Depending on the HLB value of the product they can either act as solubilzer or emulsifier.
Polysorbate 80 is its high HLB value more suitable as a solubilizer of poorly water soluble drug substances in either liquid or solid dosage forms. 
It is suitable for usage in physical mixing, melt granulation, spray drying and hot melt extrusion processes.

Polysorbate 80 can be used as an emulsifier in foods, medicines, cosmetics, textiles, agriculture, and occasionally in laboratory identification of bacteria.

Use: Polysorbate 80 is a common fragrance and essential oil solublizer as well as an emulsifying agent. It is soluble in water and alcohol and insoluble in oils. 
It is typically a co-emulsifier that is used both as a viscosity modifier and a dispersing agent for fragrances and essential oils for room sprays and linen sprays.
When combined with liquid oils, Polysorbate 80 creates a blooming bath oil. 
It can also be used in a self-emulsifying sugar or salt scrub. 
In bath bombs, you can add up to 6% as a wetting agent to help prolong fizzing in the tub.

Description
Polysorbate, a substance formulated by the reaction of sorbitan fatty acid ester (a nonionic surfactant) with ethylene oxide, is used in many foreign countries, including the U.S. and the EU, where it acts as an emulsifier, a solubilizer in many foods, including bread, cake mix, salad dressing, shortening oil and chocolate 18.

Polysorbate 80 is a hydrophilic nonionic surfactant. It is utilized as a surfactant in soaps and cosmetics and also as a lubricant in eye drops. In food or pharmaceutical products, it can act as an emulsifier. Polysorbate 80 is an excipient that is used to stabilize aqueous formulations of medications for parenteral administration or vaccinations.15

A solubilizing agent acts as a surfactant and increases the solubility of one agent in another. A substance that would not normally dissolve in a particular solution is able to dissolve with the use of a solubilizing agent.15

It is also known as an emulsifier, which helps ingredients mix together and prevent separation, and water-containing small amounts of salts, and is included in several vaccines licensed in the USA.9

Uses
Food use
Polysorbate 80 is used as an emulsifier in foods.

What is it?
This is a well known synthetic compound, also known as Tween 80.

It is an amber/golden-colored viscous liquid. It is made from polyethoxylated sorbitan (chemical compounds derived from the dehydration of sugar alcohol) and oleic acid, a fatty acid found in animal and vegetable fats.

What does it do?
Polysorbate 80 is used as an emulsifier or defoamer in foods, vitamins, medicines, and vaccines.

Why is it used in food?
It is used as a defoamer for the fermenting process of some wines, and also to bind some ice-creams and other ‘puddings’, to keep their creamy texture without separating. It is also used to bulk foods up and keep sauces smooth.

Why is it used in cosmetics?
It can also act as a surfactant in soaps and cosmetics, as well as a solubilizer – helping to dissolve ingredients so that they can more easily blend together. It is used as a solubilizer. It makes products look creamier and more attractive.


Why is it used in medicine?
It is used as an ingredient in some vaccines, as well as in some vitamins and supplements. Polysorbate 80 is used to improve the consistency of gel capsules and to make pills disperse in the stomach.

What products is it used in?
Polysorbate 80 is a versatile and useful ingredient, so it is present in quite a few products. Here is a short, generalized list of where it is most often found:

• Food shortening
• Chewing Gum
• Ice Cream
• Gelatin
• Vitamins
• Soap
• Shampoo
• Cosmetics
• Skin Creams
• Condiments
• Medicines
• Vaccines

For example, in ice cream, polysorbate is added up to 0.5% (v/v) concentration to make the ice cream smoother and easier to handle, as well as increasing its resistance to melting.
Adding this substance prevents milk proteins from completely coating the fat droplets. 
This allows them to join together in chains and nets, which hold air in the mixture, and provide a firmer texture that holds its shape as the ice cream melts.

Health and beauty use
Polysorbate 80 is also used as a surfactant in soaps and cosmetics (including eyedrops), or a solubilizer such as in a mouthwash. 
The cosmetic grade of polysorbate 80 may have more impurities than the food grade.

Medical use
Polysorbate 80 is an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the popular antiarrhythmic amiodarone.
It is also used as an excipient in some European and Canadian influenza vaccines.
Influenza vaccines contain 2.5 μg of polysorbate 80 per dose. Polysorbate 80 is found in many vaccines used in the United States.
It is also used in the culture of Mycobacterium tuberculosis in Middlebrook 7H9 broth. It is also used as an emulsifier in the estrogen-regulating drug Estrasorb.

Also used in granulation for stabilization of drug and excipients while doing IPA binding

Laboratory use
Some mycobacteria contain a type of lipase (enzyme that breaks up lipid molecules); when these species are added to a mixture of polysorbate 80 and phenol red, they cause the solution to change color, so this is used as a test to identify the phenotype of a strain or isolate.

On RODAC agar plates used in microbiological control, polysorbate 80 counteracts any disinfectants often found on sampled surfaces, thereby allowing the microbes found on these surfaces to grow.

Sorbitan Fatty Acid Esters
Polyoxyethylene sorbitan esters are synthesized by the addition, via polymerization, of ethylene oxide to sorbitan fatty acid esters. 
These nonionic hydrophilic emulsifiers are very effective antistaling agents and, thus, are used in a wide variety of bakery products. 
These emulsifiers are much more widely known as the polysorbates, e.g., polysorbate 20, 60, and 80. 
Polysorbate 20, 60, and 80 utilize lauric, stearate, and oleate, respectively, for the fatty acid portion of the molecule. 
Polysorbate 60 is a monostearate, whereas polysorbate 65 is a tristearate.

Use: Our Polysorbate 80 (polyoxyethylene sorbitan monooleate) is derived from olive oil. 
It is a non-toxic, nonionic surfactant/emulsifier and a water-soluble yellowish liquid used as a dispersing agent which allows oil and water to mix without the use of alcohol. 
It is a fragrance solubilizer and stabilizer; it lubricates and has a soothing effect on the skin. 
This skin- safe ingredient is used extensively in oil-in-water emulsions (lotions, conditioners, cream rinses, shampoos, liquid soaps, body polishes or scrubs, etc.) and also for body mists and linen sprays. 
Will be found as an ingredient in many body toiletries, cosmetics and wipes now in the market.


Emulsifier, dispersant, solubilizer, lubricant, detergent, antistat, wetting agent for cosmetics & pharmaceuticals, polishes, insecticides, leather degreasing and veterinary products.


Sorbitol is a white, sweetish, hygroscopic, crystalline sugar alcohol of six-carbon. It is found naturally in various berries and fruits. Or it is prepared synthetically by high-pressure catalytic hydrogenation of glucose sugar derived from cornstarch. It melts at 93 to 98 C depending on the form. It is used as a a sweetening agent, food additive, toothpaste, tobacco, toiletries and in cosmetics. It is used for vitamin-C fermentation. It is used as a excipient and intravenous osmotic diuretic in pharmaceutical fields. It is also used in the manufacture of polyethers for polyurethanes and surfactants. The term sorbitan describes the anhydride form of sorbitol, whose fatty acids are lipophilic whereas sorbitol body is hydrophilic. This bifunctionality in one molecule provides the basic properties useful in cleaners, detergents, polymer additives, and textile industry as emulsifiers, wetting agents, and viscosity modifiers. Sorbitan esters are rather lipophilic (or hydrophobic) surfactants exhibiting low HLB (Hydrophilic-Lipophilic Balance) values; having an affinity for, tending to combine with, or capable of dissolving in lipids (or water-insoluble). While, the ethoxylated sorbitan esters are hydrophilics exhibiting high HLB values; having an affinity for water; readily absorbing or dissolving in water. The type of fatty acid and the mole number of ethylene oxide provides diverse HLB values for proper applications.
HLB numbers describe following characterestics:

<10 : Lipid soluble (or water-insoluble)
>10 : Water Soluble
4-8 : Antifoaming
7-11 : Water-in-oil emulsion
12-16 : Oil-in-water emulsion
11-14 : Good Wetting
12-15 : Good detergency
16-20 : Stabilizing

This is a safety assessment of polysorbates as used in cosmetics. These ingredients mostly function as surfactants in
cosmetics. The safety assessment combined the polysorbates reviewed in 3 former safety assessments with polysorbates that
had not been assessed for safety into 1 report. The Panel reviewed relevant data related to these ingredients. The Cosmetic
Ingredient Review (CIR) Expert Panel (Panel) concluded that polysorbates were safe as cosmetic ingredients in the practices
of use and concentration of this safety assessment when formulated to be nonirritating. This conclusion supersedes the
conclusion reached in the 3 former safety assessments.
INTRODUCTION
This is a re-review of the available scientific literature and unpublished data relevant to assessing the safety of
polysorbates as used in cosmetics (Table 1). This safety assessment combines polysorbates reviewed previously in 3 safety
assessments with other polysorbates that have not been reviewed by the CIR Panel into a group of 82 polyethoxylated
sorbitan or sorbitol esters of fatty acids (Table 2). These ingredients have a common core structure of sorbitan or sorbitol,
etherified with polyethyoxy (PEG) chains, and esterified with fatty acids. These ingredients mostly function as surfactants in
cosmetics.
In the original safety assessment published in 1984, the CIR Panel concluded that 9 polysorbates were safe as used
These ingredients are:
1
Polysorbate 20
Polysorbate 21
Polysorbate 40
Polysorbate 60
Polysorbate 61
Polysorbate 65
Polysorbate 80
Polysorbate 81
Polysorbate 85
Other polysorbates, which are also polyethoxylated sorbitan or sorbitol esters of fatty acids and contain a PEG
moiety, have been reviewed by the CIR Panel. In 20002
, a safety assessment was published with a safe-as-used conclusion
for the following 33 PEG sorbitan/sorbitol fatty acid esters:
PEG-20 sorbitan cocoate
PEG-40 sorbitan diisostearate
PEG-2 sorbitan isostearate
PEG-5 sorbitan isostearate
PEG-20 sorbitan isostearate
PEG-40 sorbitan lanolate
PEG-75 sorbitan lanolate
PEG-10 sorbitan laurate
PEG-40 sorbitan laurate
PEG-44 sorbitan laurate
PEG-75 sorbitan laurate
PEG-80 sorbitan laurate
PEG-3 sorbitan oleate
PEG-6 sorbitan oleate
PEG-80 sorbitan palmitate
PEG-40 sorbitan perisostearate
PEG-40 sorbitan peroleate
PEG-3 sorbitan stearate
PEG-6 sorbitan stearate
PEG-40 sorbitan stearate
PEG-60 sorbitan stearate
PEG-20 sorbitan tetraoleate
PEG-30 sorbitan tetraoleate
PEG-40 sorbitan tetraoleate
PEG-60 sorbitan tetraoleate
PEG-60 sorbitan tetrastearate
PEG-20 sorbitan triisostearate
PEG-160 sorbitan triisostearate
PEG-18 sorbitan trioleate
Sorbeth-40 hexaoleate (previously PEG-40 sorbitol
hexaoleate)
Sorbeth-50 hexaoleate (previously PEG-50 sorbitol
hexaoleate)
Sorbeth-30 tetraoleate laurate (previously PEG-30
sorbitol tetraoleate laurate)
Sorbeth-60 tetrastearate (previously PEG-60 sorbitol
tetrastearate)

There were 2 ingredients that were included in the 2000 report, but were not listed in the International Cosmetic Ingredient
Dictionary and Handbook3 (Dictionary) at the time of the original review, and are not listed as cosmetic ingredients in the
current Dictionary.

 One is PEG-18 sorbitan trioleate, which has 1 use listed in the Food and Drug Administration’s (FDA)
Voluntary Cosmetic Registration Program (VCRP)5 and is therefore included in this safety assessment. However, PEG-20
sorbitan tetraoleate has no uses listed in the VCRP, so is not included in this safety assessment.
In 20016, a safety assessment was published with a safe-as-used conclusion for the following sorbitan beeswaxes:
Sorbeth-6 beeswax (formerly PEG-6 sorbitan beeswax)
Sorbeth-8 beeswax (formerly PEG-8 sorbitan beeswax)
Sorbeth-20 beeswax (formerly PEG-20 sorbitan beeswax)


At the time of this safety assessment, the Panel had recommended that cosmetic formulations containing PEGs (specifically
PEG-6, PEG-20, and PEG-75) not be used on damaged skin. Since then, PEGs have been re-reviewed and the Panel has
removed the caveat that PEGs should not be used on damaged skin.

A brief summary of pertinent data from each report is provided below. The original polysorbate reports can be found
on the CIR website, http://www.cir-safety.org/ingredients. Please refer to the original reports for detailed information.
The following 35 ingredients, which are also polyethoxylated sorbitan or sorbitol esters of fatty acids, are proposed
as additions to this group:
PEG-20 sorbitan oleate
PEG-40 sorbitan oleate
PEG-4 sorbitan stearate
PEG-4 sorbitan triisostearate
PEG-2 sorbitan trioleate
PEG-3 sorbitan tristearate

Sorbeth-30 tetraoleate
Sorbeth-40 tetraoleate
Sorbeth-60 tetraoleate
Sorbeth-3 tristearate
Sorbeth-160 tristearate
Sorbeth-450 tristearate
The VCRP reported single uses for 3 other ingredients that are not listed in the Dictionary.8
 Since there are reported
uses for these 3 ingredients, they are also included in this safety assessment:
PEG-30 sorbitan beeswax
PEG-20 sorbitan laurate
PEG-20 sorbitan stearate
CIR has conducted safety assessments of the acids and related chemical structure moieties of these ingredients
(Table 2). The Panel concluded that beeswax, coconut acid, isostearic acid, lanolin acid, oleic acid, lauric acid, myristic acid,
stearic acid, and multiple stearates were safe-as-used.9-17 An array of alkyl esters and numerous PEGs were also assessed to
be safe as used.7,18,19 Sorbitan esters have been reviewed with safe-as-used conclusions.20-22
Much of the new data included in this safety assessment were found on the European Chemicals Agency (ECHA)
website.
23-25 The ECHA website provides robust summaries of information generated by industry, and it is those summary
data that are reported in this safety assessment when ECHA is cited. Some of this data are for generic sorbitan monolaurate,
ethoxylated and sorbitan monostearate, ethoxylate; these chemicals fit the general definition of several of these ingredients
with the same CAS No. (ie, polysorbate 21, PEG-10 sorbitan laurate, PEG-40 sorbitan laurate, polysorbate 20, PEG-44
sorbitan laurate, PEG-75 sorbitan laurate, and PEG-80 sorbitan laurate all have the CAS No. 9005-64-5). It is expected that
data under these chemicals names are for one or some mixture of the ingredients with that CAS No and are useful for read
across information.
