PEG-40 Hydrogenated Castor Oil – Solubilizer for Essential Oils, Fragrance Oils, Skincare & Personal Care Formulations

PEG-40 Hydrogenated Castor Oil – Cosmetic Solubilizer & Formulation Ingredient

PEG-40 Hydrogenated Castor Oil is a polyethylene glycol derivative of hydrogenated castor oil used in a variety of cosmetic and personal care applications. It functions primarily as a solubilizer and surfactant, helping disperse suitable oil-based ingredients in aqueous formulations.

For cosmetic formulators, it can be useful when developing products that combine water with compatible fragrance oils, essential oils, or other lipophilic ingredients. Depending on the ingredient blend and formulation conditions, it can help improve the uniformity and appearance of the finished product.

PEG-40 Hydrogenated Castor Oil is used in selected skincare, hair care, cleansing, and fragrance-related formulations. The amount required depends on the oil being solubilized, the target appearance, and the complete formulation. Compatibility and stability testing are recommended before commercial production.

Whether you are manufacturing a facial mist, a personal care solution, or another compatible cosmetic product, consult the supplier’s technical documentation to select the correct grade and processing method.

Formulation & Usage Guidelines

• Determine the appropriate amount based on the oil or fragrance being solubilized.

• Conduct small-scale trials to establish a suitable solubilizer-to-oil ratio.

• Add the ingredient using the method recommended by the supplier.

• Check the final formulation for clarity, separation, odour changes, and stability.

• Test compatibility with other surfactants, preservatives, and active ingredients.

• Follow the supplier’s recommended storage and handling instructions.

Formulation note: There is no single universal solubilizer ratio for every essential oil or fragrance. The required amount can vary considerably with the oil composition and the desired final appearance.
