Glycols, 1,2-, C12-16, ethoxylated propoxylated
CAS 154248-98-3
What Is Glycols, 1,2-, C12-16, ethoxylated propoxylated?
1,2-Glycols, C12-16, ethoxylated propoxylated are synthetic compounds primarily used in industrial and cosmetic formulations as emulsifiers and solubilizers. Consumers may encounter them in hair conditioners, skin creams, and household cleaning products. These glycol derivatives help blend water and oil components, improving product texture and stability. While not fragrance ingredients themselves, they play a crucial role in maintaining the performance of scented products by ensuring even distribution of aromatic compounds.
Safety Profile
USE WITH AWARENESSWhat Does Glycols, 1,2-, C12-16, ethoxylated propoxylated Smell Like?
This material is essentially odorless, functioning primarily as a carrier rather than a fragrance ingredient. In formulations, it may slightly modify the overall scent profile by affecting volatility and diffusion rates of aromatic compounds, but contributes no distinct olfactory character of its own.
Chemistry, Properties & Perfumer Guide
The Chemistry
These compounds are synthetic polyether glycols created through the ethoxylation and propoxylation of C12-16 fatty alcohols. The process involves reacting the alcohol with ethylene oxide and propylene oxide under controlled conditions, resulting in a mixture of molecules with varying chain lengths. The final product is a complex mixture of polyoxyethylene-polyoxypropylene glycol ethers with amphiphilic properties, making them effective surfactants.

Alternatives & Comparisons
A common nonionic surfactant with similar emulsifying properties, often used as an alternative in cosmetic formulations.
Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. Consult current IFRA Standards Library before formulating.
IFRA Status
Not restricted by IFRA as it is not a fragrance material.
RIFM Assessment
Not evaluated by RIFM as it is not a fragrance material.
Sustainability
As synthetic compounds, these glycols are petroleum-derived, raising concerns about non-renewable resource use. However, their production is typically more controlled and consistent than natural alternatives, with potentially lower environmental impact from cultivation. Biodegradability varies with the degree of ethoxylation, with longer chains being less readily biodegradable.
