2022年12月26日 · The combination of silicone with methyl groups tends to make it extremely resistant to water, yet it keeps them flexible and moving free, ideal properties for a lubricant. Upon application to the skin, PEG/PPG-18/18 dimethicone forms a film on the surface while still allowing skin to “breathe”.

PEG/PPG-18/18 Dimethicone is a synthetic ingredient that has polyethylene glycol (PEG) and polypropylene glycol (PPG) polymer, a silicone based polymer and dimethicone. During the manufacturing process, it may get contaminated with toxic impurities like 1,4-dioxane - which is properly filtered out before usage in the cosmetic industry.

This ingredient is a synthetic chemical consisting of dimethicone, a silicon-based polymer and polyethylene glycol (PEG)-polypropylene glycol (PPG) polymer. May be contaminated with potentially toxic manufacturing impurities such as 1,4-dioxane. See how this product scores for common concerns.

PEG/PPG-18/18 dimethicone is a type of silicone that plays a variety of roles in cosmetic products, including functioning as a texture enhancer and cleansing (emulsifying) agent. Of note, PEG/PPG-18/18 dimethicone is described as enhancing the spreadability of formulations.

PEG/PPG-18/18 Dimethicone is a commonly used silicone-based compound that is found in many skincare and cosmetic products. It is primarily used as an emollient and skin-conditioning agent, providing a smooth and silky texture to the products it is used in.

PEG/PPG-18/18 Dimethicone imparts lubricity and softness to personal care formulations. Due to its water solubility, it can be used to formulate clear products.
