PEG 40 hydrogenated castor oil (HCO) is soluble in a range of solvents, including water, ethanol, and propylene glycol. It is a nonionic surfactant and solubilizing agent that is commonly used in the formulation of cosmetic and personal care products, pharmaceuticals, and food products.
In water, PEG 40 HCO is soluble over a wide range of concentrations, making it an effective solubilizing agent for water-soluble ingredients. It can also be used as a co-solvent to improve the solubility of poorly soluble ingredients in water.
In ethanol, PEG 40 HCO is also soluble and can be used as a solubilizing agent for ethanol-soluble ingredients.
In propylene glycol, PEG 40 HCO is soluble and can be used as a solubilizing agent for propylene glycol-soluble ingredients. It can also be used in combination with water to improve the solubility of ingredients in propylene glycol-water mixtures.
In summary, PEG 40 HCO is soluble in water, ethanol, and propylene glycol, making it a versatile solubilizing agent for a range of ingredients in different solvents.
