Shower Oil Formulation Review

Regarding your proposed shower oil formula based on the previous forum discussion, using Cyclomethicone to dissolve fragrance is a valid approach, and the overall structure of your formula is feasible for creating a lightweight shower oil.

Here's a review of the ingredients and percentages you proposed:

• Oil Soap (25%): This is the primary cleansing ingredient for your oil-based shower product. The percentage is within the recommended range (15-40%) for Oil Soap.
• Cyclomethicone (50%): Cyclomethicone is a lightweight silicone that can help provide a very light feel and aid in dissolving fragrance. While it can be used at high percentages, 50% is quite high compared to typical recommendations (1-20%) in some product types. This high level will contribute significantly to the thin, light feel you desire, but you might experiment with lower percentages if needed.
• Fractionated Coconut Oil (10%): This is a suitable carrier oil for fragrance and provides moisturizing properties. 10% is a reasonable amount.
• Oil Blender (3.5%): Oil Blender is necessary when using Oil Soap to prevent separation. Your proposed percentage is within the recommended range (1-5%, with 3.0-3.5% recommended).
• Tocopheryl Acetate (0.5%): This is Vitamin E, included as an antioxidant to help protect the oils in the formula from going rancid. The percentage is within the typical usage rate (0.1-1%).
• Ethylhexyl Salicylate (1%): This ingredient is a chemical sunscreen. Including a sunscreen in a wash-off product like shower oil is generally not necessary as it will be rinsed off and not provide sun protection benefits. You may consider omitting this ingredient.
• Fragrance (10%): While Cyclomethicone and Fractionated Coconut Oil can help dissolve fragrance, a 10% concentration of fragrance is quite high for a wash-off product and could potentially cause skin irritation for some individuals. You might consider reducing the fragrance level.

Mixing Instructions:

Based on the ingredient properties, you would typically mix the Oil Soap, Cyclomethicone, Fractionated Coconut Oil, and Oil Blender together and heat to around 70°C while stirring gently until fully combined. Allow the mixture to cool to below 50°C before adding the Tocopheryl Acetate and Fragrance, stirring well after each addition.

In summary, your formula provides a good starting point for a lightweight shower oil, leveraging the properties of Cyclomethicone and Oil Soap. Consider the points raised about the percentages of Cyclomethicone and Fragrance, and the inclusion of Ethylhexyl Salicylate, and adjust according to your desired outcome and skin sensitivity.
