PEG-16 HYDROGENATED CASTOR OIL.

This ingredient expertly functions as an emulsifier, enabling the stable incorporation of immiscible oil and water phases within cosmetic formulations. It further acts as a solubilizer, facilitating the homogenous dispersion of oil-soluble components like fragrances into water-based solutions. As a surfactant, it effectively reduces surface tension, promoting even product distribution and aiding in cleansing processes. Applied to the skin, it serves as both an emollient, forming a mildly occlusive layer to minimize transepidermal water loss, and a humectant, drawing moisture from the environment to the skin, resulting in enhanced moisturization and a noticeably softer feel. Notably, related PEGylated castor oils have demonstrated potential to bolster skin barrier function, support stratum corneum repair, and exhibit anti-inflammatory and anti-itching benefits.
