PEG-33 CASTOR OIL

Description

PEG-33 Castor Oil is a versatile ingredient widely used in skincare and cosmetic formulations. This modified castor oil is created through the process of ethoxylation, where ethylene oxide is added to castor oil, resulting in a water-soluble compound. The number 33 indicates the average number of ethylene oxide units added per molecule of castor oil.

As an emollient and surfactant, PEG-33 Castor Oil helps to improve the texture and spreadability of products while enhancing their moisturizing properties. It acts as a solubilizer, aiding in the incorporation of fragrances and essential oils into water-based formulations. This ingredient also functions as an emulsifier, facilitating the mixing of oil and water-based components in cosmetic products.

PEG-33 Castor Oil is particularly beneficial in cleansing formulations, such as facial cleansers and shampoos, where it helps to remove dirt and oil without overly stripping the skin or hair. Its mild nature makes it suitable for sensitive skin types. In haircare products, it can improve manageability and add shine to the hair shaft. While generally considered safe for cosmetic use, individuals with sensitive skin should perform a patch test before regular application.
