Description 1. Concentration: Typically used at 0.5-5% of the total formulation, depending on the specific application and desired effect. 2. Incorporation: – Add Soldoc PG410 to the oil phase of your formulation. – Heat both the oil and water phases to about 70-75°C (158-167°F). – Slowly add the water phase to the oil phase while stirring continuously. – Homogenize the mixture using a high-shear mixer for optimal emulsion stability. 3. pH Range: Effective in a wide pH range, typically 3-12, making it versatile for various formulations. 4. Compatibility: Works well with most cosmetic ingredients, including other emulsifiers, oils, and active ingredients. 5. Cold Processing: Can be used in cold-process formulations, making it energy-efficient and suitable for heat-sensitive ingredients. 6. Synergy: Often combined with co-emulsifiers or thickeners for enhanced stability and texture. Tips for Formulators: – Start with lower concentrations and adjust as needed for optimal stability and texture. – Perform stability testing at various temperatures to ensure the emulsion remains stable over time. – For extra stability in challenging formulations, consider combining with a small amount of a co-emulsifier. HLB Description: Excellent PEG-free emulsifier, which has a HLB* of 14,5. (*Hydrophilic-Lipophilic-Balance) The HLB-value can be used in order to predict the scope of a surface-active substance: HLB-values between 0 and 3 are typical for anti-foaming products. HLB-values between 2 and 8 indicate a water-in-oil emulsifier (the HLB-value is most suitable between 4 and 6) HLB-values between 8 and 18 indicate an oil-in-water emulsifier. Lavender & Rosemary Oil-to-Milk Facial Cleanser 46% (23ml) Sweet Almond Oil 20% (10ml) Sunflower Oil 10% (5ml) Castor Oil 21% (10.5ml) Emulsifier Polyglyceryl-4 Caprate 1.2% (0.6ml) ( -16 drops) Lavender Essential Oil 0.8% (0.4ml) ( -11 drops) Rosemary Essential Oil 1% (0.5ml) Vitamin E Oil Method Weigh all your carrier oils in a beaker, mix well. Weigh your essential oils and Vitamin E. Weigh your emulsifier into an empty beaker and start mixing it with a whisk. While whisking, start adding you’re your carrier oil mixture in small amounts of 1-2ml to start with. Mix well after each addition. Once all your carrier oil has been added and mixed in well, you can add your essential oil and Vit E, mixture. Transfer your product into a dropper bottle or the packaging of your choice.
