What Is Alcohols, C11-15-secondary, ethoxylated?
Alcohols, C11-15-secondary, ethoxylated is a synthetic surfactant commonly found in industrial cleaners, detergents, and some personal care products. It helps dissolve oils and improve product spreadability. While not a traditional fragrance ingredient, it may contribute subtle background notes in functional formulations where scent is secondary to performance.
Safety Profile
USE WITH AWARENESSWhat Does Alcohols, C11-15-secondary, ethoxylated Smell Like?
This ethoxylated alcohol blend has a faint, clean odor reminiscent of diluted soap or laundry detergent. The scent profile is neutral with subtle waxy undertones, lacking distinct top/middle/base evolution. In formulations, it primarily functions as a surfactant rather than a fragrance ingredient, contributing minimal olfactory impact beyond a generic ‘clean’ background note.
Chemistry, Properties & Perfumer Guide
The Chemistry
Alcohols, C11-15-secondary, ethoxylated is a synthetic surfactant produced by ethoxylation of secondary alcohols with ethylene oxide. The C11-15 carbon chain length provides balanced hydrophobicity while the ethoxylation introduces hydrophilic character. This amphiphilic structure enables effective surface tension reduction. The product is typically a mixture of molecules with varying degrees of ethoxylation.
