Application Notes
|
|
Plastics industry
|
Cetearyl alcohol can be used as an additive for plastics to improve their flowability and processing properties.
|
|
Coatings and inks
|
Cetearyl alcohol can be used as a dispersant and stabilizer in coatings and inks to improve their performance .
|
|
Candle Industry
|
Due to its waxy properties, cetearyl alcohol is sometimes used in the preparation of candles.
|
|
Pharmaceutical manufacturing
|
In topical formulations, cetearyl alcohol increases the viscosity of w/o and o/w emulsions. It stabilizes the emulsion and has a co-emulsifying effect, thus reducing the amount of surfactant required to form a stable emulsion.
Hexadecyl alcohol is used in pharmaceuticals to reduce the release of water-soluble drugs.
|
|
Daily chemical industry
|
In cosmetics and personal care products, cetearyl alcohol can be used to make surfactants, such as acetone, natural fatty alcohols and ethylene oxide adducts. It can also be used to manufacture defoamers, flotation agents, softeners, paddy field heat-insulating agents, water surface covering agents, raw materials for pharmaceutical ointments, and colorants for color films.
