CYPERUS ESCULENTUS ROOT OIL.

Valuable CAS 223748-92-3 / FRAGRANCE

This nourishing plant-derived oil, extracted from the roots of Cyperus esculentus, is a rich source of unsaturated fatty acids (60-70% oleic acid, 8-12% linoleic acid), tocopherols, phytosterols, and polyphenols. It provides robust antioxidant protection, enhances skin barrier function, and delivers emollient and anti-inflammatory benefits to the skin and scalp.

Summary

Masking Fragrance Emollient Antioxidant Anti-inflammatory

Science

Mechanism of Action

Cyperus esculentus root oil acts as a potent antioxidant, primarily due to its high concentration of tocopherols (including alpha- and gamma-tocopherol), which effectively neutralize free radicals in skin tissues. Its abundant unsaturated fatty acids, including 60-70% oleic acid and 8-12% linoleic acid, contribute to its emollient properties, helping to soften the skin, reinforce the skin barrier, and minimize transepidermal water loss. The oil also exhibits anti-inflammatory effects and can deeply hydrate and protect both the scalp and hair.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

While generally regarded as safe for cosmetic use and rated low for general concerns by EWG Skin Deep, the CIR classified it as 'safe with restrictions'. One source raises concerns about potential interaction with androgen receptors and a plausible risk of inducing cancer if absorbed at concentrations higher than typically found in safely assessed cosmetics, advising against its use on large surface areas or areas with high absorption. A cream containing this oil has elicited 'some level of allergic reactions'. However, SkinSAFE deems it suitable for Teen, Baby, and Eyelid applications.

Verdict

Valuable

Cyperus Esculentus Root Oil offers valuable antioxidant, emollient, and anti-inflammatory benefits across all skin types, though its use requires careful consideration of the CIR's 'safe with restrictions' classification and reported allergic reactions.
