CAS 24938-91-8
What Is Poly(oxy-_1,_2-_ethanediyl)_, _-_tridecyl-__-_hydroxy-?
This synthetic polymer is primarily used in industrial applications and personal care products as an emulsifier or surfactant. You might encounter it in shampoos, conditioners, or cleaning products where it helps blend oil and water components. While not a traditional fragrance ingredient, its functional properties make it valuable in product formulations where texture and stability are key.
Safety Profile
GENERALLY SAFEWhat Does Poly(oxy-_1,_2-_ethanediyl)_, _-_tridecyl-__-_hydroxy- Smell Like?
This ingredient is virtually odorless, functioning primarily as a non-fragrant component in formulations. It may impart a very faint, clean, slightly waxy character at high concentrations, but generally has no significant olfactory impact. Its role is structural rather than aromatic, helping to stabilize fragrance compositions without contributing top, heart, or base notes.

Chemistry, Properties & Perfumer Guide
The Chemistry
This polyethylene glycol derivative is a synthetic polymer created through the ethoxylation of tridecyl alcohol. The resulting molecule features a hydrophilic polyoxyethylene chain and a lipophilic tridecyl group, giving it amphiphilic properties. Industrial synthesis typically involves reacting the alcohol with ethylene oxide under controlled conditions. The degree of ethoxylation can vary, affecting the molecule’s solubility and surfactant properties.
