PEG-150 Distearate is well known for its thickening abilities in some formulations, particularly those based on amphoterics and soaps.

PEG-150 Distearate is a versatile and practical thickening agent commonly used in personal care and cosmetic products. 

PEG-150 Distearate is often used in creams, lotions, and other products to improve their texture and stability. 

PEG-150 Distearate helps to create a smooth, consistent consistency that is easy to apply and feels pleasant on the skin. 

PEG-150 Distearate also has excellent emulsifying properties, helping to keep oil-based and water-based ingredients mixed in a stable, homogeneous mixture. 

PEG-150 Distearate is also highly effective at dispersing pigments, fragrances, and other active ingredients evenly throughout a product, ensuring that they are delivered effectively and consistently.

PEG-150 DISTEARATE

PEG-150 Distearate is polyethylene glycol diester of stearic acid. 

PEG-150 Distearate) is defined as the polyethylene glycol (PEG) diester of stearic acid, wherein the PEG has an average degree of polymerization of 150 oxyethylene repeat units corresponding to an average molecular weight (MW) of 6,600 g/mol. 

What is PEG-150 DISTEARATE used for?

PEG-150 Distearate is used mainly as a thickener in shampoos, conditioners, shower gels, face washes, hand washes, shaving creams, baby-care products, etc.

PEG-150 Distearate is a polyethylene glycol diester of stearic acid. HLB 18.9 (gives oil-in-water emulsions). 

PEG-150 distearate has an HLB value of about 18; thus, it can also be used as a nonionic emulsifier for o/w systems. 

In addition, the use of PEG-150 distearate in color cosmetics, hair conditioners, and shaving preparations is also known.

To overcome the need for the hot processing of formulas containing PEG-150 distearate to achieve effective dissolution, as previously described, raw material suppliers also provide the ingredient in concentrated aqueous blends with typical anionic, amphoteric, and/or nonionic surfactants such as sodium trideceth sulfate, cocamidopropyl betaine, and PEG-80 sorbitan laurate. 

Such blends simplify formulating by premixing commonly employed ingredients, such as the amphoteric and nonionic surfactants used in baby shampoos, and enabling ambient-temperature processing.
