Hydrogenated Castor Oil (CAS 8001-78-3), commonly known as HCO or Castor Wax, is a hard, brittle, high-melting-point waxy solid produced by the controlled hydrogenation of pure castor oil, primarily utilized as a critical rheology modifier and thixotropic agent in industrial coatings, greases, and personal care formulations. This Castor wax compound functions as an effective structural stabilizer and thickener in Hydrogenated castor oil based systems, providing superior anti-settling properties for pigments in paints and improving the consistency of high-viscosity lubricants and cosmetic sticks. To support industrial-scale requirements, we provide bulk supply with competitive factory pricing and ensure rigorous quality control through customized specifications alongside standard technical documentation, including MSDS, TDS, COA.

Applications:
It is one of the superior emulsifying solubilizers at present, and is an ideal emulsifying and volume enhancer for clear transparent serum, toner, mouthwash, shampoo, shampoo skin care and other products, which can be used for oil-soluble fragrance, fungicide, coolant, mosquito repellent, insecticide, sunscreen, various animal and plant extracts and other water-insoluble substances. It is used for the production and manufacture of all kinds of transparent water-based washing, makeup, and daily necessities. Polyoxyethylene-40 hydrogenated castor oil is extremely safe, without any irritation and allergy to the skin, is a commonly used emulsifying and volume enhancer in intravenous injection and large infusion in pharmaceutical preparations, and is a commonly used emulsifying volume enhancer in intravenous nutritional fat emulsion, vitamin fat emulsion and other large infusions, so the safety of use in skin care products is needless to say.
How to use:
This product can be used in water, alcohol solutions, and lotions to solubilize essential oils, synthetic fragrances, and functional skin care ingredients. When using, the solid powder or viscous liquid should be dissolved and diluted with a small amount of solvent first, then added to the product to be dissolved, and mixed with the solubilized substance at 30~50 degrees in a ratio of 1:4~1:10 and stirred well until clear and transparent. The dosage of CO-40 can be gradually increased from 1:4 to 1:10, and the appropriate ratio and required dosage to meet the solubilization requirements can be explored. In addition, the following mixing sequence is also extremely important, which is the key to maintaining efficient solubilization and emulsification: the solubilization and emulsification of oily liquid components can be directly mixed with CO-40 first, and the solubilization of solid components should be dissolved with a small amount of appropriate solvent, and then mixed evenly with CO-40, so that the components to be solubilized and CO-40 are dissolved, and then mixed with a small amount of water (about 3~4 times the amount) evenly, and the solution is in a clear and transparent state, and then diluted with a large amount of water to the required concentration.
FAQ - Technical & Supply Chain
-
Q:
Is Hydrogenated Castor Oil (CAS 8001-78-3) the same as PEG-40 Hydrogenated Castor Oil?
A: No, CAS 8001-78-3 refers to the pure, water-insoluble waxy solid (HCO) used as a thickener, whereas PEG-40 Hydrogenated Castor Oil is a water-soluble ethoxylated derivative used as an emulsifier or solubilizer. -
Q:
What is the primary function of HCO in coating applications?
A: It acts as a thixotropic additive that prevents pigment sedimentation during storage and controls sagging during application by building a viscosity network that breaks down under shear stress.
