PEG-6 Caprylic/Capric Glycerides is a polyethylene glycol (PEG) derivative of medium-chain glycerides—specifically mono-, di-, and triglycerides of caprylic and capric fatty acids—that has been ethoxylated with an average of six ethylene oxide units. This structure confers a non-ionic surfactant profile with excellent emulsification, solubilization, and emollient properties, enabling it to blend oil- and water-based ingredients into stable formulations. In skincare systems, it functions as an emollient and lightweight moisturizer, helping to replenish skin lipids and deliver a smooth, non-greasy skin feel. Its solubilizing capacity facilitates the incorporation of lipophilic actives (like vitamins and essential oils) into aqueous phases, improving the bioavailability and sensory experience of creams, lotions, micellar waters, makeup removers, and other facial and body care products. Its compatibility with aqueous surfactant systems also makes it a key ingredient in gentle cleansing and makeup removal formulations, where it supports effective removal of sebum and particulate impurities without excessive stripping of natural moisture.

In haircare formulations, PEG-6 Caprylic/Capric Glycerides operates as a non-ionic surfactant, solubilizer, and emollient that contributes to improved wetting, foam quality, and conditioning performance. When included in shampoos, conditioners, and mild surfactant systems like shower gels, it can help disperse active ingredients evenly and enhance the silky after-feel on hair fibers. Its refatting and solubilizing properties help minimize dryness by supporting moisture retention on the scalp and hair cuticle, while its gentle action makes it suitable for frequent-use products designed for sensitive or reactive scalps. Because it dissolves readily in both water and oil phases, it is a popular choice in dual-phase and multi-function haircare products aimed at cleansing, conditioning, and improving texture.
