What is PEG-45M?
PEG-45M is a polyethylene glycol polymer commonly used in hair care products. It is a type of synthetic compound derived from petroleum and composed of repeating ethylene glycol units.
In hair products, PEG-45M functions primarily as a thickener and film-former, helping to create a desirable texture and hold for styling. The health evidence on PEG-45M is generally limited, but it's largely considered safe for topical use. However, as with any synthetic compound, sensitivity in some individuals can occur.
When reading product labels, it's useful to know that PEG-45M is part of a broader class of polyethylene glycols, which vary in molecular weight and application, but generally share similar safety profiles.
Commonly found in: shampoos, conditioners, styling gels, hair sprays
