Ceteareth 25 Ginonic
Ceteareth 25 Ginonic CSA 25 is a nonionic surfactant and emulsifier derived from the ethoxylation of cetearyl alcohol, incorporating approximately 20 ethylene oxide units per molecule. It appears as a white to off-white waxy solid or viscous liquid, depending on temperature and formulation. This emulsifier is widely used in cosmetic, pharmaceutical, and industrial formulations for its excellent ability to stabilize oil-in-water emulsions, improve texture, and enhance the sensory properties of finished products. Its high hydrophilic-lipophilic balance (HLB) makes it especially effective in forming stable emulsions and solubilizing lipophilic ingredients in aqueous phases. Ceteareth 20 is valued for its mildness, broad compatibility, and multifunctional performance.
Cocodiethanolamide (CDEA)
Cocodiethanolamide (CDEA) is a viscous, amber to dark brown liquid derived from the reaction of coconut oil fatty acids with diethanolamine. It is a non-ionic surfactant and foam stabilizer commonly used in personal care and cleaning products. CDEA enhances foam quality, viscosity, and skin conditioning properties in formulations. Due to its excellent emulsifying and thickening abilities, it is widely used as a secondary surfactant to boost the performance of primary detergents. It is valued for its biodegradability, mildness, and compatibility with various surfactants and other ingredients in cosmetics and industrial formulations.
