Hydroxyethyl Cellulose (HEC) is a non-ionic cellulose ether that is derived from cellulose by introducing hydoxyethyl groups to its structure through a chemical reaction with ethylene oxide. The degree of substitution (DS) of hydroxyethyl groups in HEC can vary depending on the desired properties of the final product. It is white in colour and the final product is in a powder form.
Hydroxyethyl Cellulose (HEC) is a water-soluble polymer that is highly soluble in water and has several desirable properties, including good water solubility, non-toxicity, biodegradability and high compatibility with other ingredients. It is widely used in various personal care products, pharmaceuticals, paints and coatings, construction materials and oil and gas drilling.
As a non-ionic polymer, HEC is compatible with:
Salts and electrolytes - Surfactants (anionic, cationic, non-ionic) - Latex emulsions - Pigments and fillers.
HEC is widely used in cosmetics formulations due to its mild nature. This makes it highly versatile in complex formulaitons.
WIDE PH STABILITY
HEC remians stable in a wide PH range, (approximately 2-12), making it suitable for:
Acidic formulations (cleaners), Neutral systems (cosmetics), Alkaline systems (cement mortars).
Applications
Shampoo, Conditioner, Skin lotions and creams, Facial cleansers, Toothpast.
Functions
Thickener, stabilizer, Emulsion enhancer, Provides smooth texture and feel.
