PEG-25 Castor Oil is commonly utilized as an effective oil-soluble emulsifier and solubilizer, characterized by its clear liquid form and water dispersibility. With an HLB value of 13, it serves as a versatile pigment dispersant and wetting agent. Notably resistant to hydrolysis, PEG-25 Castor Oil is suitable for use in a variety of acidic and alkaline formulations. Furthermore, it improves the gelling properties of other surfactants within water-in-oil emulsions, enhancing the stability and functionality of such formulations.
What is PEG-25 Castor Oil?
PEG-25 Castor Oil is an ethoxylated derivative of castor oil, produced through the addition of 25 moles of ethylene oxide. It is a clear liquid and functions as an oil-soluble emulsifier.
What are the primary uses of PEG-25 Castor Oil?
PEG-25 Castor Oil serves multiple functions, including acting as a pigment dispersant, solubilizer, and wetting agent. It is utilized in formulations to enhance the dispersion of pigments, improve solubility of ingredients, and increase the wetting properties of products.
Can PEG-25 Castor Oil be used in both acidic and alkaline products?
Yes, PEG-25 Castor Oil is resistant to hydrolysis, which allows it to be effectively used in a variety of formulations, including both acidic and alkaline products.
How does PEG-25 Castor Oil contribute to emulsion formulations?
In water-in-oil emulsions, PEG-25 Castor Oil enhances the gelling properties of other surfactants, contributing to a stable and effective formulation.
What is the HLB value of PEG-25 Castor Oil, and what does it signify?
The HLB (hydrophilic-lipophilic balance) value of PEG-25 Castor Oil is 13. This indicates that it is more hydrophilic, making it suitable for creating oil-in-water emulsions and improving the solubilization of oil-based ingredients in aqueous systems.
Is PEG-25 Castor Oil water-soluble?
PEG-25 Castor Oil is dispersible in water, allowing it to be incorporated into aqueous formulations while maintaining its emulsifying properties.
