C12-14 SEC-PARETH-7 is a nonionic surfactant that belongs to the family of ethoxylated secondary alcohols, which are commonly used in cosmetic, personal care, and industrial formulations for their emulsifying, solubilizing, and dispersing properties.
The term “C12-14” refers to the number of carbon atoms in the alkyl chain of the parent alcohols, indicating that these are secondary alcohols with carbon chains ranging from 12 to 14 atoms, while “Sec” (secondary) indicates that the hydroxyl (-OH) group is attached to a secondary carbon, meaning it is connected to two other carbon atoms instead of being at a terminal position. The “-7” in the name represents the average number of ethylene oxide (EO) units attached to each molecule, which determines its hydrophilic-lipophilic balance (HLB) and overall solubility in water.
This molecule has an amphiphilic structure, meaning it contains both a hydrophobic (oil-loving) tail, derived from the C12-14 secondary alcohol, and a hydrophilic (water-loving) head, derived from the ethoxylated chain.
This structure allows C12-14 SEC-PARETH-7 to reduce the surface tension between water and oil phases, enabling the formation of stable emulsions, the solubilization of oils and fragrances, and the dispersion of other active ingredients in formulations.
C12-14 SEC-PARETH-7s moderate ethoxylation makes it particularly suitable for balanced emulsification, providing sufficient water solubility without excessively weakening interactions with oils and lipophilic components.
