PEG-5 Castor Oil is a versatile ethoxylated derivative of castor oil, distinguished as an oil-soluble liquid emulsifier with limited water solubility due to its short polyethylene glycol chain and an HLB value of 4. It serves as a pigment dispersant, solubilizer, and wetting agent, recognized under the trade name Lumulse™ CO-5. This product offers remarkable resistance to hydrolysis and is compatible with both acidic and alkaline formulations, making it suitable for a diverse range of applications. Additionally, PEG-5 Castor Oil can enhance the gelling properties of other surfactants in water-in-oil emulsions, broadening its utility in various industrial and cosmetic formulations.
What is PEG-5 Castor Oil and what are its primary uses?
PEG-5 Castor Oil is an ethoxylated castor oil derivative, specifically a liquid emulsifier, with a short polyethylene glycol chain. Its primary applications include use as a pigment dispersant, solubilizer, and wetting agent. Due to its oil solubility and water insolubility, it is particularly effective in formulations that require emulsification in oil-based systems.
How soluble is PEG-5 Castor Oil in oils and water?
PEG-5 Castor Oil is soluble in oils but insoluble in water. This property makes it suitable for use in oil-based formulations where it acts as an effective emulsifier.
What is the HLB value of PEG-5 Castor Oil and what does it signify?
The hydrophilic-lipophilic balance (HLB) value of PEG-5 Castor Oil is 4, indicating it is more lipophilic (oil-loving) than hydrophilic (water-loving). This makes it particularly useful in creating water-in-oil emulsions.
Can PEG-5 Castor Oil be used in both acidic and alkaline formulations?
Yes, PEG-5 Castor Oil is resistant to hydrolysis and can be utilized in both acidic and alkaline formulations. This property allows it to maintain stability and efficacy across a wide pH range.
In what type of emulsions does PEG-5 Castor Oil enhance surfactant properties?
PEG-5 Castor Oil enhances the gelling properties of other surfactants specifically in water-in-oil emulsions. This can help in achieving a more stable and effective emulsion, improving product performance.
