HYDROGENATED CASTOR OIL ISOSTEARATE.

Valuable / SKIN CONDITIONING, VISCOSITY CONTROLLING

Hydrogenated Castor Oil Isostearate is a multifunctional emollient, providing deep moisturization to both skin and hair by enhancing their natural softness and elasticity. It forms a delicate, non-greasy protective film that effectively reduces transepidermal water loss. This ingredient also acts as a skin conditioning agent and contributes to the stability of cosmetic formulations.

Summary

Emollient Skin-conditioning agent Viscosity controlling

Science

Mechanism of Action

This ingredient operates as an emollient by creating a lightweight, non-occlusive barrier on the skin's surface. This film significantly prevents moisture evaporation, thereby boosting hydration, elasticity, and softness without leaving a greasy residue. Beyond its emollient properties, it functions as a skin conditioning agent, improving the tactile quality and appearance of the skin, and serves as a viscosity controlling agent to ensure uniform product texture and consistent distribution in formulations.

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

While Hydrogenated Castor Oil Isostearate itself has not been specifically reviewed by the Cosmetic Ingredient Review (CIR) Expert Panel, related ingredients like Hydrogenated Castor Oil and its PEG-derivatives (e.g., PEG-30 and PEG-40 Hydrogenated Castor Oil) have been deemed safe for cosmetic use, including at concentrations up to 100% provided they are formulated to be non-irritating. However, some individuals, particularly those with sensitive skin, may experience localized sensitivities or allergic reactions, such as itching, redness, or swelling; therefore, patch-testing a new product is advisable. No specific FDA status or SCCS review was found for this ingredient.
