hydrogenated polyisobutene

Description

Hydrogenated polyisobutene is a synthetic oil widely used in cosmetic and personal care products. This colorless, odorless substance is derived from the hydrogenation of polyisobutene, a polymer of isobutylene. Its molecular structure allows it to function as an emollient, moisturizer, and viscosity control agent in various skincare formulations.

The ingredient's low molecular weight enables it to spread easily on the skin, creating a smooth, non-greasy feel. It forms a protective barrier on the skin's surface, helping to reduce transepidermal water loss and maintain hydration. Hydrogenated polyisobutene is particularly valued for its ability to enhance the texture and spreadability of products such as lip balms, lotions, and foundations.

In addition to its moisturizing properties, hydrogenated polyisobutene acts as a replacement for silicone oils in some formulations. It provides similar sensory benefits without the potential environmental concerns associated with silicones. The ingredient is generally considered safe for use in cosmetics and is non-comedogenic, making it suitable for a wide range of skin types. Its stability and resistance to oxidation contribute to the extended shelf life of products containing this versatile compound.
