PEG-40 Hydrogenated Castor Oil | Emulsifier | CAS# 61788-85-0

• Origin: Italy
• CAS Number: 61788-85-0

PEG-40 Hydrogenated Castor Oil It is an ethoxylated derivative of hydrogenated castor oil, commonly used in the cosmetics, personal care, and fragrance industries. It is notable for its ability to dissolve, emulsify, and aid in the dispersion of oil components in a water-based substrate.

Thanks to its structure containing both oil-loving and water-loving components, PEG-40 Hydrogenated Castor Oil helps combine previously insoluble ingredients, thereby creating a more homogeneous and stable formulation. It is also a common ingredient in formulations containing fragrances, essential oils, vegetable oils, and other oil-based components.

1. Description and characteristics of PEG-40 Hydrogenated Castor Oil

PEG-40 Hydrogenated Castor Oil is typically used in liquid or semi-solid form, ranging in color from white to pale yellow depending on quality grade and storage conditions. The material exhibits non-ionic surfactant properties, which reduce the surface tension between the oil and water phases, thereby aiding in mixing and dispersion.

A notable characteristic of PEG-40 Hydrogenated Castor Oil is its ability to solubilize poorly water-soluble substances. Therefore, this ingredient is often chosen when formulations require adding small amounts of oil, essential oils, or fragrances to a water-based system while maintaining appropriate clarity or consistency.

2. What are the uses of PEG-40 Hydrogenated Castor Oil?

PEG-40 Hydrogenated Castor Oil has many functions in formulations, the most common of which are:

• Emulsifier: It helps to form and maintain an emulsion between oil and water.
• Solubler: It helps to introduce oil, fragrance, or essential oil components into a water-based solution.
• Non-ionic surfactants: It helps reduce surface tension and improve dispersion.
• Dispersant: This helps distribute the poorly soluble ingredients more evenly throughout the formula.
• Formula stabilizing agent: This helps to reduce the phenomenon of delamination in some product systems.

In practice, the specific function of an ingredient depends on the ratio of use, the formulation system, and accompanying ingredients. Therefore, PEG-40 Hydrogenated Castor Oil should not be considered a substitute for all other emulsifiers.

3. Applications in cosmetics

PEG-40 Hydrogenated Castor Oil is widely used in cosmetics and personal care products, especially in formulations containing oil ingredients but requiring a water base or stable dispersion system.

The raw materials can be used in product groups such as:

• Facial cleanser and cleansing gel
• Toner and facial lotion
• Hair conditioning spray and hair care spray
• Shampoo, conditioner
• Skincare products
• Creams and lotions
• Deodorant products
• Perfumes and fragrance products
• Cosmetic formulas containing essential oils or fragrance oils.

In liquid-based products, PEG-40 Hydrogenated Castor Oil is particularly useful when manufacturers need to disperse a quantity of flavoring or oil into a water base, helping to prevent oil from floating or separating.
