PEG-25 STEARATE

Description

PEG-25 Stearate is a versatile emulsifier and surfactant commonly used in skincare and cosmetic formulations. This synthetic compound is derived from the esterification of stearic acid with polyethylene glycol (PEG). Its molecular structure consists of a hydrophobic stearate chain attached to a hydrophilic PEG chain, allowing it to effectively bridge oil and water phases in products.

In skincare formulations, PEG-25 Stearate functions as an emollient and emulsifier, helping to create stable emulsions and improving the texture and spreadability of creams and lotions. It aids in the even distribution of active ingredients throughout the product, ensuring consistent efficacy. This ingredient also contributes to the moisturizing properties of skincare products by forming a protective barrier on the skin's surface, reducing transepidermal water loss.

PEG-25 Stearate is generally well-tolerated by most skin types and is considered safe for use in cosmetic products. However, individuals with sensitive skin should perform a patch test before incorporating products containing this ingredient into their skincare routine. The concentration of PEG-25 Stearate in formulations typically ranges from 0.1% to 5%, depending on the specific product requirements and desired texture.
