Cetearyl Alcohol

Cetearyl alcohol functions to inhibit greasy sensation, reduce the viscosity of waxy raw materials, and stabilize cosmetic emulsions. It is a versatile ingredient that plays a significant role in cosmetics, food, and pharmaceuticals. Its application helps enhance product quality and stability, and it also contributes positively to skin moisturization and protection.

Application Fields
1. Plastic Industry: Cetearyl alcohol can be used as an additive in plastics to improve fluidity and processing performance.
2. Coatings and Inks: In coatings and inks, cetearyl alcohol acts as a dispersant and stabilizer to enhance their properties.
3. Candle Industry: Due to its waxy nature, cetearyl alcohol is sometimes used in candle making.
4. Pharmaceutical Manufacturing: In topical formulations, cetearyl alcohol increases the viscosity of both w/o and o/w emulsions. It stabilizes emulsions and has a co-emulsifying effect, thereby reducing the amount of surfactant needed to form a stable emulsion. Cetearyl alcohol is used in pharmaceuticals to slow the release of water-soluble drugs.
5. Daily Chemical Industry: In cosmetics and personal care products, cetearyl alcohol is used to produce surfactants such as平平加 (Pingpingjia), natural fatty alcohol ethoxylates, etc. It is also utilized in making defoamers, flotation agents, softeners, paddy field insulation agents, water surface covering agents, and as a raw material for pharmaceutical ointments.

Stability and Storage Conditions
Storage Conditions: Store in a cool, well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Keep containers sealed. Separate from oxidizers, acids, acid anhydrides, and acyl chlorides. Avoid mixed storage. Equip with appropriate types and quantities of fire-fighting equipment. The storage area should have leak emergency handling equipment and suitable containment materials.
