PEG-33

Description

PEG-33 is a polyethylene glycol derivative widely used in cosmetic and personal care formulations. This synthetic ingredient functions primarily as an emulsifier, solubilizer, and humectant. With a molecular weight of approximately 1,500 Da, PEG-33 is a medium-chain polymer that strikes a balance between water solubility and emollient properties.

In skincare products, PEG-33 helps to improve texture and stability by creating uniform mixtures of oil and water-based ingredients. It enhances the penetration of active ingredients into the skin, potentially increasing their efficacy. As a humectant, PEG-33 attracts and retains moisture, contributing to improved skin hydration.

The safety profile of PEG-33 is generally favorable when used in concentrations typical for cosmetic formulations. However, it may cause irritation in individuals with sensitive skin or compromised skin barriers. PEG-33 is often used in cleansers, moisturizers, and hair care products due to its ability to create smooth, easily spreadable formulations. Its versatility makes it a valuable ingredient in various personal care applications, from leave-on treatments to rinse-off products.
