PPG-7
Description
PPG-7, also known as Polypropylene Glycol-7, is a synthetic polymer widely used in skincare and cosmetic formulations. This versatile ingredient functions primarily as a humectant and emollient, attracting and retaining moisture in the skin while providing a smooth, non-greasy feel. PPG-7 is part of the larger family of polypropylene glycols, with the number 7 indicating its average molecular weight.
In skincare products, PPG-7 helps improve texture and spreadability, enhancing the overall user experience. Its ability to form a protective barrier on the skin's surface aids in reducing transepidermal water loss, thus promoting better hydration. This ingredient is particularly beneficial in leave-on formulations such as lotions, creams, and serums.
PPG-7 is generally well-tolerated by most skin types and is considered safe for use in cosmetics. It can be found in various products, including moisturizers, sunscreens, and hair care items. Due to its low molecular weight, PPG-7 penetrates the skin more easily than higher-weight polypropylene glycols, potentially enhancing the delivery of other active ingredients in a formulation.
