Triethylhexanoin description

A synthetic mixture of glycerine and a triglyceride fatty acid known as 2-ethylhexanoic acid. Triethylhexanoin functions primarily as a solvent, occlusive agent, skin-conditioning emollient, and hair conditioner. Triethylhexanoin is considered safe as used in cosmetics, where it is used in amounts up to 100% (in certain face and neck treatments) and 63% in lipsticks. Despite such high concentrations, many leave-on skin care products with triethylhexanoin use it in amounts between 3–5%.
