Peg-80 Hydrogenated Castor Oil

PEG-80 Hydrogenated Castor Oil is a polyethylene-glycol derivative of hydrogenated castor oil used as a nonionic surfactant, emulsifier, and solubilizer.

What it is

PEG-80 Hydrogenated Castor Oil is made by reacting hydrogenated castor oil with roughly 80 units of ethylene oxide, producing a highly water-dispersible nonionic surfactant. It helps blend oils and water and is used to solubilize fragrances and oily actives into aqueous or gel formulas. In sunscreens it can support emulsion stability and contribute to a light, water-rinsable texture.

Safety & warnings

PEG-80 Hydrogenated Castor Oil is generally well tolerated and is widely used in rinse-off and leave-on products. As with other ethoxylated ingredients, it can occasionally contribute to sensitivity in individuals reactive to PEG compounds. It is not a recognized fragrance allergen.

Origin & sourcing

It is a semi-synthetic ingredient derived from castor oil (from Ricinus communis seeds) that is hydrogenated and then ethoxylated with ethylene oxide.

Questions everyone asks

What does PEG-80 Hydrogenated Castor Oil do?

It is a nonionic surfactant that emulsifies oils with water and helps dissolve fragrances and oily ingredients into the formula.

Is it derived from castor oil?

Yes. It is made from hydrogenated castor oil that has been reacted with ethylene oxide to make it water-dispersible.
