BIS-PEG/PPG-15/5 DIMETHICONE

Description

BIS-PEG/PPG-15/5 DIMETHICONE is a multifunctional silicone-based ingredient widely used in skincare and cosmetic formulations. This synthetic compound belongs to the silicone elastomer family and is prized for its versatile properties. It acts as an emollient, emulsifier, and texture enhancer, contributing to the smooth, silky feel of products.

The ingredient's molecular structure combines silicone with polyethylene glycol (PEG) and polypropylene glycol (PPG) chains, resulting in enhanced compatibility with both water and oil-based components. This unique composition allows BIS-PEG/PPG-15/5 DIMETHICONE to function as an effective emulsion stabilizer, helping to prevent separation in formulations.

In skincare applications, it forms a breathable, non-occlusive film on the skin's surface, which helps to reduce transepidermal water loss and improve product spreadability. Its lightweight nature makes it suitable for various skin types, including oily and acne-prone skin. The ingredient also demonstrates mild conditioning properties, leaving the skin feeling soft and smooth without excessive greasiness.

BIS-PEG/PPG-15/5 DIMETHICONE is commonly found in foundations, sunscreens, moisturizers, and other leave-on skincare products, where it contributes to improved texture, stability, and overall performance.
