Overview
Octyl caprylate (CAS 2306-88-9 ), also known as octyl octanoate, is a synthetic ester produced from caprylic acid and octanol. Registered under FEMA 2811 , it functions as an emollient, lubricant, and solvent carrier.
This versatile chemical serves as a flavoring agent across personal care, food, and industrial applications. In personal care formulations, it acts as a lightweight emollient and solvent carrier for active ingredients.
It is commonly found in skin creams, sunscreens, and color cosmetics. Food and flavor manufacturers use it as a FEMA-approved flavoring ingredient, contributing fatty, creamy top notes to various products.
It is frequently utilized in confectionery, dairy, and beverage products. Industrial lubricant formulators incorporate it as a base fluid or additive in metalworking fluids and specialty lubricants.
These applications are ideal where low viscosity and good lubricity are required. It also functions as a solvent for fragrance compounds and lipophilic actives in both rinse-off and leave-on systems.
Octyl caprylate is supplied as a clear, low-viscosity liquid in drum and IBC quantities. Food-grade material meeting specific standards is available for flavor applications to ensure safety.
Cosmetic and technical grades serve personal care and industrial end uses. Purity levels typically range from 98% upward depending on the intended application and specific customer requirements.
