HPMCHydroxypropyl methylcellulose (HPMC) is a polymer used in skin care as a film-forming substance, binding agent, emulsion stabilizer and texture enhancer. It also boosts foaming abilities in cleansing products.
Through its many properties and uses, it can help a skin care formula’s appearance and usability, giving cosmetics desirable, homogenous textures that are easy to apply to skin.
Hydroxypropyl methylcellulose is a hydrophilic (water-loving) modified cellulose polymer that’s water soluble. It appears as a white or off-white powder in its raw material form and is typically sourced from cotton.
In recent research, it’s been tested as a material used in the creation of hydrogels to promote wound healing. Beyond this, hydroxypropyl methylcellulose is a common food additive.
The Cosmetic Ingredient Review Expert Panel determined it’s safe for use in cosmetics. Usage levels of hydroxypropyl methylcellulose range from 0.2–1% depending on desired texture (higher amounts are used in gel formulations).
