PPG-33

Description

PPG-33, also known as Polypropylene Glycol-33, is a synthetic polymer widely used in skincare and personal care formulations. This versatile ingredient functions primarily as an emollient, humectant, and solvent. Its molecular structure allows it to form a protective barrier on the skin, helping to reduce transepidermal water loss and maintain hydration.

In skincare products, PPG-33 enhances texture and spreadability, contributing to a smooth, non-greasy feel upon application. It aids in the even distribution of active ingredients throughout formulations, ensuring consistent product efficacy. As a humectant, it attracts and retains moisture, promoting skin hydration and potentially improving overall skin texture.

PPG-33 is compatible with a wide range of cosmetic ingredients, making it valuable in various product types, including lotions, creams, and serums. Its solvent properties assist in dissolving and stabilizing other ingredients, particularly oil-soluble components. This characteristic is especially useful in creating stable emulsions and suspensions.

While generally considered safe for topical use, as with any synthetic ingredient, some individuals may experience sensitivity. It's advisable to perform patch tests when introducing new products containing PPG-33 into a skincare routine.
