Hydroxyethylcellulose (HEC) is a modified cellulose polymer used as a gelling and thickening agent in skincare and personal care products. It is known for its ability to produce crystal clear gel products and thicken the aqueous phase of cosmetic emulsions. HEC is also commonly used to thicken shampoos, body washes, and shower gels. It is a water-soluble polymer derived from cellulose, a natural sugar found in plant cell walls. HEC is synthetically made by reacting ethylene oxide with alkali-cellulose.
HEC is a sustainable, nonionic, bio-based and biodegradable water-soluble high quality rheology modifier. It allows to thicken, improve emulsion stability and enhance the sensory experience for hair and skin care applications. Proven performance in delighting consumers for more than 30 years.
All skin types except those that have an identified allergy to it.
Potential safety concern with hydroxyethylcellulose: contamination with 1,4-dioxane, a substance known to potentially contribute to some cancers.
It is recommended to add HEC to room temperature water with a neutral pH to prevent lumping. Once hydrated, it can be heated, and the pH can be adjusted as needed.

HEC is a modified cellulose polymer; used as a gelling and thickening agent. It is also used in food, pharmaceutical, and industrial applications. Hydroxyethylcellulose is also considered to be a rheology modifier, which means it can adjust the flow of a product. It is often used in shampoos and cleansers to enhance foam creaminess and richness, and in hair gels to provide a soft hold without stickiness or flaking.
