Simmondsia Chinensis (Jojoba) Oil PEG-8 Esters
What is Simmondsia Chinensis (Jojoba) Oil PEG-8 Esters?
Simmondsia Chinensis (Jojoba) Oil PEG-8 Esters is produced by esterifying fatty acids from jojoba seed oil, sourced from the seeds of the Simmondsia chinensis shrub native to arid regions. Jojoba oil consists of long-chain wax esters chemically similar to human sebum. The PEG-8 modification involves reacting these esters with polyethylene glycol (PEG-8), a short-chain polymer, to create a more water-dispersible form. In cosmetics, it serves primarily as a skin and hair conditioning agent, emollient, and emulsifying surfactant. It deposits a lightweight film on skin and hair, enhancing softness and smoothness while aiding in the stabilization of emulsions in creams, lotions, shampoos, and conditioners. This dual hydrophilic-lipophilic nature allows it to improve product spreadability and provide a non-greasy texture.
