PEG-9 STEARATE

Description

PEG-9 Stearate is a versatile emulsifier and surfactant commonly used in skincare and cosmetic formulations. This synthetic ingredient is derived from ethoxylated stearic acid and polyethylene glycol (PEG). Its primary function is to stabilize emulsions, allowing oil and water-based components to mix seamlessly in various products.

In skincare formulations, PEG-9 Stearate helps create smooth, uniform textures and enhances the spreadability of creams, lotions, and other topical preparations. It also acts as a mild cleansing agent, aiding in the removal of dirt and excess oils from the skin's surface. The ingredient's emollient properties contribute to improved skin feel and hydration.

PEG-9 Stearate is generally considered safe for use in cosmetics and personal care products. Its molecular structure allows it to be easily rinsed off, reducing the likelihood of residue buildup on the skin. However, individuals with sensitive skin should perform a patch test before regular use, as with any new skincare ingredient.

When formulating products containing PEG-9 Stearate, it is essential to consider its optimal pH range and compatibility with other ingredients to ensure product stability and efficacy.
