Substitute for PEG-40 Sorbitan Peroleate in Body Oil

It appears that PEG-40 Sorbitan Peroleate is not currently available. For your body oil formulation containing Isopropyl Myristate and Sesame Oil, a suitable alternative emulsifier/solubilizer can be used to achieve a similar texture or rinse-off property.

Suggested Substitutes

• PEG-40 Hydrogenated Castor Oil: This is a common and versatile solubilizer and emulsifier often used in oil-based products to help them disperse in water or rinse off more easily. It is a good potential replacement.
• Polysorbate 85: Another option from the Polysorbate family, which can function as an emulsifier in oil systems.

Suggested Proportions

The exact proportions will depend on the desired feel and rinse-off properties of the body oil. However, a typical starting point for a body oil formulation using these components could be:

• Sesame Oil: 50-60%
• Isopropyl Myristate: 20-30%
• Substitute Emulsifier (e.g., PEG-40 Hydrogenated Castor Oil or Polysorbate 85): 10-20%

For example, you could start with:

• Sesame Oil: 60%
• Isopropyl Myristate: 20%
• PEG-40 Hydrogenated Castor Oil: 20%

Always test the formulation in small batches and adjust the proportions based on your desired results. Isopropyl Myristate helps provide a light, non-greasy feel and improves spreading, while Sesame Oil acts as a nourishing carrier oil. The emulsifier helps to blend the oils and potentially allows the product to be more easily rinsed off with water.
