PEG-100 Hydrogenated Castor Oil
What PEG-100 Hydrogenated Castor Oil is & what it does
PEG-100 Hydrogenated Castor Oil is a polyethylene glycol derivative of hydrogenated castor oil, made by reacting the oil with ethylene oxide. It functions mainly as a nonionic surfactant and emulsifier, helping to mix oil and water phases and to solubilize fragrances or oily actives into a stable formula. In sunscreens it can help disperse oil-soluble UV filters evenly throughout the product.
What does PEG-100 Hydrogenated Castor Oil do in skincare?
PEG-100 Hydrogenated Castor Oil acts as a surfactant and emulsifier in skincare and sunscreen formulas. It helps blend oil and water, solubilize fragrances or oily actives, and keep the product stable and uniform. It is a functional formulation ingredient rather than an active with a direct skin benefit.
Is PEG-100 Hydrogenated Castor Oil comedogenic?
PEG-100 Hydrogenated Castor Oil is generally considered low on the comedogenic scale and is widely used in lightweight and facial products. Individual responses vary, so a product's overall formula matters more than any single ingredient. If you are acne-prone, patch testing a new product is a reasonable precaution.
Is PEG-100 Hydrogenated Castor Oil natural or synthetic?
PEG-100 Hydrogenated Castor Oil is semi-synthetic. It starts from castor oil, a natural plant oil, which is then hydrogenated and reacted with ethylene oxide to add polyethylene glycol units. The result is a processed ingredient derived from a natural base.
