Primosil™ CS (Cyclopentasilaxane)

Primosil™ CS (Cyclopentasiloxane) is a popular silicone fluid in personal care and cosmetics, valued for its lightweight and non-greasy texture. It provides a silky and smooth feel when applied to the skin, enhancing the application of a wide range of products, including lotions, serums, and makeup foundations. It evaporates quickly, leaving behind a soft, velvety finish without any residue, making it ideal for formulations that require a clean, non-oily feel. Additionally, it helps to spread other cosmetic ingredients evenly, improving the overall performance and consistency of products. This ingredient is also beneficial in hair care, where it adds a glossy shine and reduces frizz by coating the hair strands, making them more manageable. Moreover, its barrier properties help to protect the skin and hair from moisture loss, contributing to better hydration and condition.
