PEG-40 Hydrogenated Castor Oil

CAS Number:

61788-85-0

Chemical Formula:

Mixture (Polyethylene glycol derivative of hydrogenated castor oil)

EINECS/ELINCS No:

500-147-5

Description:

PEG-40 Hydrogenated Castor Oil is a versatile,non-ionic surfactant, solubilizer, and emulsifier derived from castor oil. It is valued for its ability to combine oil and water, enhance product clarity, and provide mild cleansing and moisturizing properties.

Uses:

It is a multifunctional ingredient used across cosmetic and personal care formulations for its emulsifying and solubilizing power.

· Skin & Body Care: Used in face creams, lotions, sunscreens, cleansers, body washes, and shower gels to stabilize emulsions and solubilize oils or fragrances into water-based formulas.

· Hair Care: Found in shampoos and conditioners as a gentle surfactant and emollient that helps cleanse while imparting softness.

· Makeup & Fragrance: Essential for suspending pigments, essential oils, and perfumes in aqueous systems, ensuring product clarity and stability.

Origin:

It is a semi-synthetic ingredient. It is produced through a two-step process:

1. Hydrogenation: Castor oil (from the Ricinus communis plant) is hydrogenated to increase its chemical stability.

2. Ethoxylation: The hydrogenated oil is reacted with an average of 40 moles of ethylene oxide (the "40" in the name), which makes it water-soluble.

What does PEG-40 HYDROGENATED CASTOR OIL do in a formulation?

Its primary functions are:

• Solubilizing (primary function for fragrances and oils)
• Emulsifying (Oil-in-Water)
• Surfactant / Cleansing
• Emollient

Safety Profile:

· General Assessment: Considered safe for cosmetic use. It is typically non-irritating and well-tolerated by the skin at standard use levels.

· Key Considerations: As an ethoxylated ingredient, high-purity grades are processed to minimize residual impurities like 1,4-dioxane and ethylene oxide. It is generally not a significant skin sensitizer.

· Use Concentration: Recommended usage in final formulations typically ranges from 1% to 25%, with a common level for solubilizing fragrances being 3-5%
