PEG-40 STEARATE

PEG-40 STEARATE; PEG-40 STEARATE is classified as : Emulsifying, Surfactant. CAS Number 9004-99-3. INN Name: macrogol ester 2000. Chem/IUPAC Name: Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxooctadecyl)-.omega.-hydroxy- (40 mol EO average molar ratio) What Is It? Polyethylene Glycol (PEG) Stearates (PEG-2 Stearate, PEG-6 Stearate, PEG-8 Stearate, PEG-12 Stearate, PEG-20 Stearate, PEG-32 Stearate, PEG-40 Stearate, PEG-50 Stearate, PEG-100 Stearate, PEG-150 Stearate) are esters of polyethylene glycol and stearic acid. The PEG Stearates are soft to waxy solids that are white to tan in color. In cosmetics and personal care products, PEG Stearates are used in skin creams, conditioners, shampoos, body cleansers and soapless detergents. Why is it used in cosmetics and personal care products? The PEG Stearates clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away. Scientific Facts: The PEG Stearates are produced from stearic acid, a naturally occurring fatty acid. The numerical value of each PEG Stearate corresponds to the average number of ethylene oxide monomers in the polyethylene chain. Polyethylene glycol ingredients may also be named with a number that indicates molecular weight, for example polyethylene glycol (400) stearate is another name for PEG-8 Stearate.What Is It?

PEG 40 Stearate * A surfactant and cleansing agent * Please read TIA’s article on What Is It: PEGs PEG 40 Stearate is used in cosmetics and beauty products primarily as a surfactant and cleansing agent, because PEG Stearates' ability to clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away, according to CosmeticsInfo.org. However, it is also seen as an emollient, because of secondary properties. * A surfactant and cleansing agent * Please read TIA’s article on What Is It: PEGs Functions: PEG 40 Stearate is used in cosmetics and beauty products primarily as a surfactant and cleansing agent, because PEG Stearates' ability to clean the skin and hair by helping water to mix with oil and dirt so that they can be rinsed away, according to CosmeticsInfo.org. However, it is also seen as an emollient, because of secondary properties. Unlike typical PEGs, (whose identifying number corresponds to their molecular weight) the numerical value of each PEG Stearate corresponds to the average number of ethylene oxide monomers in the polyethylene chain (from 2 - 150). Despite the many fears regarding PEGs, they are seen as an ingredient in a large number of products because of their diverse properties. In a study published in the Toxicology journal in 2005, entitled "Safety assessment on polyethylene glycols (PEGs) and their derivatives as used in cosmetic products," it was concluded that: "Taking into consideration all available information from related compounds, as well as the mode and mechanism of action, no safety concern with regard to these endpoints could be identified. Based on the available data it is therefore concluded that PEGs of a wide molecular weight range (200 to over 10,000), their ethers (laureths. ceteths, ceteareths, steareths, and oleths), and fatty acid esters (laurates, dilaurates, stearates, distearates) are safe for use in cosmetics." PEG 40 Stearate is not considered to be an irritant or sensitizer (it gave only minimal irritation in studies up to 100%), and are CIR and FDA approved for use, but not on broken skin. algon ST 400 2- hydroxyethyl octadecanoate (peg-40) lipopeg 39-S lipopeg 39-S flakes myrj S40 nikkol MYS-40MV nikkol MYS-40V pegosperse 1750 MS pegosperse 1750-MS poly(oxy-1,2-ethanediyl), .alpha.-(1-oxooctadecyl)-.omega.-hydroxy- (40 mol EO average molar ratio) polyethylene glycol (40) monostearate polyethylene glycol (40) stearate polyoxyethylene (40) monostearate polyoxyethylene (40) stearate polyoxyl 40 stearate NF grade polyoxyl 40 stearate regular grade
