Caprylic/Capric Glycerides is a chemical compound obtained from glycerin and capric and caprylic acids.

The name describes the structure of the molecule:

• Caprylic/Capric indicate that the glycerides are derived from caprylic and capric fatty acids, typically extracted from coconut oil or palm kernel oil.
• Glycerides indicates that these fatty acids are esterified with glycerol, forming a triglyceride that is useful as an emollient and stabilizer in many beauty products.

Chemical Industrial Synthesis Process

• Preparation of reagents. The main reagents include glycerin and caprylic and capric fatty acids.
• Esterification. Glycerin is reacted with caprylic and capric fatty acids in the presence of an acid catalyst such as sulfuric acid. The esterification reaction forms monoglycerides, diglycerides, and triglycerides of the fatty acids.
• Transesterification reaction. The resulting mixture may be further treated via transesterification to optimize the ratio of monoglycerides, diglycerides, and triglycerides.
• Purification. The glyceride mixture is purified to remove impurities and catalyst residues using techniques such as fractional distillation or filtration.
• Stabilization. The purified glycerides are stabilized to ensure stability during transportation and storage, preventing oxidation and degradation.
• Quality control. The purified glycerides undergo rigorous quality testing to ensure they meet standards for purity, efficacy, and safety. These tests include chemical analysis, spectroscopy, and microbiological testing.

What it is used for and where

Caprylic/Capric Glycerides are known for their ability to provide a smooth, silky feel to the skin without leaving an oily residue. They are ideal for improving the texture of formulations, making them lighter and more easily absorbed. These ingredients are used in a wide range of products, including skin creams, lotions, lip balms, and foundations, where they act as solvents for insoluble ingredients and enhance the skin barrier. They are also valued for their compatibility with other ingredients and their stability in formulations.

Cosmetics - INCI Functions

• Skin conditioning agent - Emollient. Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. In practice, they have the ability to create a barrier that prevents transepidermal water loss.  Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
