PEG 40 hydrogenated castor oil is used in cosmetics as a solubiliser, emulsifier, surfactant and emollient. It is derived from Castor oil and is useful in producing products that disperse in water whilst offering good moisturising properties.
Characteristics of Peg 40 Hydrogenated Castor Oil
PEG 40 Hydrogenated Castor Oil is not seen as an irritant or sensitiser and has been shown to only cause minimal irritation in concentrations up to 100%. PEG 40 Hydrogenated Castor Oil allows oil and water to combine and it has a surfactant ability which acts as a cleansing agent, lifting dirt from the skin and hair. Peg 40 has the additional property of being an emollient.
How to Use Peg-40 Hydrogenated Castor Oil
For optimal results, use PEG-40 Hydrogenated Castor Oil at a concentration of 3-10% within your formulation. This range is ideal for achieving both emulsification and solubilisation.
Step-by-Step Guide to Using PEG-40 Hydrogenated Castor Oil
- Measure the Ingredient
Accurately measure PEG-40 Hydrogenated Castor Oil to be within the 3-10% concentration range based on the total weight of your formulation.
- Combine with Oil Phase
Add PEG-40 Hydrogenated Castor Oil to the oil phase of your formulation. Ensure thorough mixing to blend it well with other oil-soluble ingredients.
- Heat and Mix
Heat the oil phase to the recommended temperature (usually around 70-75°C) while stirring continuously to ensure even distribution and solubilization of ingredients.
- Combine Oil and Water Phases
Gradually add the water phase to the oil phase while continuing to mix. PEG-40 Hydrogenated Castor Oil will help to form a stable emulsion, preventing separation of oil and water components.
- Cool and Continue Mixing
Allow the mixture to cool while stirring. This process ensures that the emulsion remains stable and that the final product has a smooth, consistent texture.
- Final Adjustments
Once the mixture has cooled to room temperature, you can add any heat-sensitive ingredients, such as essential oils or active botanicals. Mix thoroughly to ensure even distribution.
