PPG-20 METHYL GLUCOSE ETHER.

Valuable CAS 61849-72-7 / HAIR CONDITIONING, SKIN CONDITIONING

PPG-20 Methyl Glucose Ether is a versatile polyether derived from glucose, functioning primarily as a humectant and emollient to enhance skin hydration and softness. It also acts as a sophisticated sensory enhancer and fragrance fixative within cosmetic formulations.

Science

Mechanism of Action

This ingredient operates through several key mechanisms to optimize skin health and product performance. As a humectant, it actively draws and binds atmospheric moisture, effectively increasing and maintaining skin hydration for a noticeably softer feel. Concurrently, its emollient properties allow it to establish a protective, non-occlusive film on the skin's surface. This barrier effectively minimizes transepidermal water loss (TEWL), lubricates the skin, and contributes to a smooth, supple texture. Beyond direct skin benefits, PPG-20 Methyl Glucose Ether functions as a skin conditioning agent, enhancing the overall texture and sensory appeal of formulations, and notably can mitigate the stinging sensation often associated with alcohol-based products. Furthermore, it acts as an effective fragrance fixative, slowing the evaporation of volatile aromatic compounds and thereby prolonging the intensity and longevity of a product's scent profile.
