PEG-45M

Last update on Feb 2, 2023
Peg-45M is a stabilizing ingredient used in a wide range of personal care and cosmetic products. It is a white powdery substance that is soluble in water and is silica free. Further, Peg-45M can also be used as a binder in the formulations. It is good for increasing the viscosity of personal care and cosmetic products and improving their textures. The chemical formula of Peg-45M is (C2H4O)mult-H2O.

What is PEG-45M used for?

Peg-45M is a useful ingredient in the cosmetic and personal care industry. It can be found in products such as shampoos, cleansers, and moisturizers.
  • Hair care: It is a good viscosity-increasing ingredient that thickens hair care formulations and improves their texture. The addition of this ingredient also enhances the spreadability of the product
  • Skin care: It binds the ingredients present in a formulation and improves the quality of the final product. It is also used to obtain the desired viscosity
  • Cosmetic products: It acts as an emulsion stabilizer that works well with the other ingredients present in the formulation and makes it more stable. It prevents the oil-based and water-based ingredients from separating, thus increasing the quality of the product

Origin

The ingredient Peg-45M is ethylene glycol’s polymer. The number here indicates the units of ethylene glycol present in the ingredient and the letter ‘M’ along with it represents 1000. So, Peg-45M contains 45000 units of ethylene glycol.

Safety Profile

Peg-45M is safe to be used in personal care and cosmetic products in small quantities. It is sometimes considered toxic because of the production of 1,4-dioxane during the manufacturing process. However, proper filtration processes eliminate this issue. Peg-45M is good for all skin and hair types. But, a patch test should be performed prior to full usage.
