POLY(1,4-BUTANEDIOL)-8

Description

POLY(1,4-BUTANEDIOL)-8, also known as polybutylene glycol-8, is a synthetic polymer derived from 1,4-butanediol. This versatile compound serves as a humectant and emollient in various skincare formulations. Its primary function is to attract and retain moisture, helping to maintain skin hydration and improve overall texture.

The molecule's structure allows it to form a thin, non-occlusive film on the skin's surface, which helps reduce transepidermal water loss without impeding skin breathability. This property makes it particularly beneficial for individuals with dry or dehydrated skin conditions. POLY(1,4-BUTANEDIOL)-8 also exhibits a low molecular weight, enabling it to penetrate the upper layers of the epidermis and deliver hydration more effectively than larger molecules.

In addition to its moisturizing properties, this ingredient demonstrates excellent compatibility with a wide range of cosmetic ingredients, enhancing the stability and texture of formulations. It is generally well-tolerated by most skin types and is considered non-irritating and non-sensitizing. POLY(1,4-BUTANEDIOL)-8 is commonly found in moisturizers, serums, and other hydrating skincare products, particularly those designed for dry or mature skin.
