HYDROXYPROPYL CELLULOSE
What is HYDROXYPROPYL CELLULOSE?
Hydroxypropyl Cellulose is a semisynthetic, non-ionic, water-soluble cellulose ether derived from natural cellulose sources like wood pulp or cotton linters, modified with hydroxypropyl groups. In skincare products, it functions primarily as a film-forming agent, thickener, and stabilizer, creating a protective film on the skin or hair, enhancing texture, and improving the viscosity of formulations such as gels, creams, and serums. It is widely used in cosmetics, pharmaceuticals, and food due to its biocompatibility and ability to form flexible, transparent films.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Suspending agent
Keeps insoluble particles (pigments, beads, actives) evenly dispersed by increasing viscosity or forming a network, preventing settling and separation.
Binding
Provides cohesion by helping ingredients stick together, improving the strength and integrity of pressed powders, tablets, or solid bars.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
