INCI: Peg-90M

What is Peg-90M?

PEG-90M is polyethylene glycol, a polymer of ethylene glycol. If we look at the nomenclature, M refers to 10,0000 units so PEG 90M has 90,000 units of monomer ethylene glycol attached in the polymeric chain. For a solvent to be considered as useful in any product, it has to have some characteristics. PEG-90M has all the characteristics suitable for the ideal solvent. PEG-90M is a very mild, water-soluble, non-ionic polymer compatible with many other ingredients used in cosmetic products.

Use & Benefits:

PEG-90M can attract water molecules and make it available to use for the skin or hair. So, it is used as a binder, emulsifier, and viscosity controller in cosmetic products. Various reactive molecules it contains makes it a good stabilizer for any product. It helps calm any other reactive groups in various ingredients and thus gives stability throughout the shelf life. As an emulsifier, it inhibits the water and oil-based components to get separated from each other. This is particularly useful when the product is undergoing any temperature or humidity changes drastically. It also functions as a binder and keeps all the components of the product to stick and bonded together. PEG is a very acceptable binder with the least cross-reaction capabilities, so desirable thickness can be achieved.  For any product, viscosity is a very critical factor, too viscous or too watery may not only make it look unacceptable but also not customer-friendly. PEG-90M is used to achieve acceptable viscosity. It is generally used in shampoos, conditioners, creams, lotions, and other skin and hair care products.
