PEG-7 Glyceryl Cocoate (CAS 68201-46-7) — Citrus None Note Fragrance Ingredient
PEG-7 Glyceryl Cocoate
CAS 68201-46-7
What Is PEG-7 Glyceryl Cocoate?
PEG-7 Glyceryl Cocoate is a synthetic ingredient commonly found in personal care products like shampoos, conditioners, and body washes. It acts as a gentle emulsifier and skin conditioner. This ingredient helps blend water and oil-based components while providing a silky feel to formulations. Its mild nature makes it suitable for sensitive skin applications where traditional surfactants might be too harsh.
Safety Profile
GENERALLY SAFEWhat Does PEG-7 Glyceryl Cocoate Smell Like?
PEG-7 Glyceryl Cocoate is nearly odorless, with a faint, clean, slightly waxy character that doesn’t interfere with fragrance compositions. Its neutral scent profile makes it an excellent base for perfumed formulations where it won’t compete with or distort delicate top notes. The material has no significant olfactory evolution or dry-down characteristics, functioning purely as a functional carrier in fragrance systems.
Chemistry, Properties & Perfumer Guide
The Chemistry
PEG-7 Glyceryl Cocoate is a synthetic ester formed by reacting coconut fatty acids with glycerin and ethylene oxide. The PEG-7 designation indicates an average of 7 ethylene oxide units per molecule. This structure creates an amphiphilic molecule with both hydrophilic (polyethylene glycol) and lipophilic (coconut fatty acid) portions. The material is typically produced through base-catalyzed ethoxylation reactions under controlled conditions to achieve the desired degree of ethoxylation.

A more water-soluble option for clear formulations requiring excellent fragrance solubilization.
Safety, Regulatory & Sustainability
⚠ Regulatory Disclaimer
General reference only. Consult current IFRA Standards Library before formulating.
IFRA Status
No IFRA restrictions apply to PEG-7 Glyceryl Cocoate.
RIFM Assessment
Considered safe for use in cosmetic applications according to RIFM standards.
Sustainability
As a synthetic material, PEG-7 Glyceryl Cocoate’s environmental impact depends on manufacturing processes. The coconut oil feedstock is renewable, but ethylene oxide production has significant energy requirements. Biodegradability is moderate due to the polyethylene glycol chains. Formulators should balance performance needs with environmental considerations when selecting this ingredient.
