PEG-30 CASTOR OIL

Last update on Jul 3, 2025

PEG-30 Castor Oil is a potent surfactant that helps blend oil- and water-based ingredients in cosmetic products. It improves the texture of formulations to create smooth and stable products that feel light and oil-free. Common in cleansers, micellar waters, and makeup removers, it helps dissolve impurities on the skin and provides residue-free cleansing. In hair care products like shampoos, PEG-30 Castor Oil improves foam quality and reduces the harshness of other surfactants present in a formulation. In its raw form, this ingredient appears as a clear yellow liquid. It is safe for both rinse-off and leave-on products but is not suitable for natural or clean beauty applications due to its synthetic production.

What is PEG-30 CASTOR OIL used for?

PEG-30 Castor Oil is a versatile ingredient offering benefits to both skin and hair care industries. Primarily, it is a surfactant and allows for proper mixing of oil- and water-based ingredients in formulations.

Skin care: In skin care products like creams and lotions, PEG-30 Castor Oil is responsible for improving the texture and spreadability. As a dispersing agent, it aids in the even distribution of pigments and fragrances in a product. PEG-30 Castor Oil also helps lift oil and dirt from the skin when used in cleansers. It is gentle and lightweight on the skin.

Hair care: PEG-30 Castor Oil is used in hair care products to aid the thorough cleansing of the scalp and shafts without stripping off the natural oils. It provides good foaming properties that enhance the cleansing experience. PEG-30 Castor Oil is a common ingredient in shampoos and hair conditioners.

Origin

PEG-30 Castor Oil comes from natural castor oil which undergoes ethoxylation to add 30 molecules of ethylene oxide. This process increases the water-solubility of castor oil and changes it from hydrophobic to amphiphilic - having both water-loving and oil-loving properties.

Safety Profile

PEG-30 Castor Oil is safe for topical application when used within the recommended usage levels of 1% - 5%. In low concentrations, it is non-irritating and non-sensitizing. However, PEG compounds contain contamination risks and can be dangerous if not purified properly during manufacturing. Additionally, PEG-30 Castor Oil is a non-biodegradable ingredient and is avoided by green cosmetics.
