PEG-150 Pentaerythrityl Tetrastearate, identified by its CAS number 130249-48-8, is a highly versatile and valued ingredient in the personal care and cosmetic industry. This chemical compound serves as a multi-functional agent, primarily recognized for its capabilities as an effective thickener, emulsifier, and pearling agent. Its unique molecular structure allows it to significantly enhance the texture, stability, and aesthetic appeal of a wide range of formulations.

Chemically, PEG-150 Pentaerythrityl Tetrastearate is a tetraester of stearic acid and a polyethylene glycol ether of pentaerythritol, with an average of 150 moles of ethylene oxide. It typically appears as a white or off-white solid, available in powder or flake form, possessing a mild characteristic odor. The synthesis process involves reactions of pentaerythritol with ethylene oxide to form a polyethylene glycol derivative, followed by esterification with stearic acid, resulting in a compound with a high stearic acid content, contributing to its performance in various applications.

One of its primary functions is to act as a viscosity increasing agent in aqueous systems. This makes it indispensable for achieving the desired consistency in liquid cosmetic products, from thin solutions to rich, creamy textures. As an emulsifier and co-emulsifier, it plays a crucial role in stabilizing oil-in-water or water-in-oil emulsions, preventing separation and ensuring a smooth, uniform product. Furthermore, its ability to impart a luxurious, pearlescent effect makes it a preferred choice for visually appealing formulations, enhancing the overall user experience.

The applications for PEG-150 Pentaerythrityl Tetrastearate are extensive across the personal care sector. It is commonly found in a variety of products, including shampoos, conditioners, body washes, shower gels, and liquid soaps, where it contributes to desirable rheology and foam stability. In skincare, it is utilized in creams, lotions, and cleansers for its emulsion stabilizing properties. It can also be incorporated into makeup items such as foundations, as well as hair dyes, tonics, and other hair grooming aids. Notably, it is increasingly being considered as an effective alternative to other thickening agents like Cocamide DEA and Cocamide MEA, offering a robust performance profile.

Regarding safety, PEG-150 Pentaerythrityl Tetrastearate has been subject to thorough evaluation by expert panels, including the Expert Panel for Cosmetic Ingredient Safety (CIR). These assessments have concluded that the ingredient is safe for use in cosmetics under current practices and concentrations. Due to its large molecular size, absorption through the skin is generally not expected, minimizing systemic exposure. Studies have also indicated a low potential for skin irritation, allergic skin reactions, and genotoxicity.

Concerns surrounding trace impurities such as ethylene oxide and 1,4-dioxane, which can be byproducts of the ethoxylation process, have been addressed. Current good manufacturing practices (cGMPs) are in place to limit these impurities to very low concentrations (e.g., 1 part-per-million for ethylene oxide and 5 ppm for 1,4-dioxane), ensuring that the finished cosmetic products pose no significant hazard to consumers. While generally safe, it's worth noting a specific consideration for individuals prone to fungal acne; some fatty acid components, including stearic acid in this compound, might theoretically be metabolized by certain Malassezia species, although this is a niche concern for specific sensitive conditions.
