Modifying Oil Soap Formula for Increased Foam and Soft Skin Feel

Question

Regarding the following oil-based liquid soap formula for dry, easily irritated skin, which yields a clear texture:

Formula:

Oil Soap™: 45%
Fractionated Coconut Oil: 46%
Jojoba Oil: 5%
Vitamin E Acetate: 1%
Oil Blender: 3% (Necessary in the formula to prevent separation)

Steps:

Mix all ingredients together.
Heat to 70°C and stir at a low speed (not exceeding 500 rpm) until dissolved and clear.
Wait for it to cool down to no more than 50°C, then add Vitamin E.
Stir or mix until combined.

Fragrance or Essential Oil can be added to the formula as usual.

Based on this formula, if I want to increase the foam and make the skin feel softer after bathing, which ingredients should I add and approximately what percentage?

Oil Soap Formula Modification for Increased Foam and Soft Skin Feel

To increase foam and leave the skin feeling softer after using your oil-based liquid soap formula, you can add the following ingredients:

Cocamidopropyl Betaine: This is a gentle amphoteric surfactant that acts as a co-surfactant to boost foam production, creating a richer and finer lather.
Glycerin: This is a humectant and emollient that helps attract and retain moisture on the skin, contributing to a softer feel after rinsing.

Here is a suggested modified formula with example percentages. You can adjust the percentages slightly based on your desired level of foam and skin feel, ensuring the total remains 100%:

Oil Soap™: 45%
Fractionated Coconut Oil: 36% (Adjusted from 46% to make space for new ingredients)
Jojoba Oil: 5%
Vitamin E Acetate: 1%
Oil Blender: 3%
Cocamidopropyl Betaine: 7%
Glycerin: 3%

Total: 100%

Mixing Steps:

Combine Oil Soap™, Fractionated Coconut Oil, Jojoba Oil, Vitamin E Acetate, Oil Blender, Cocamidopropyl Betaine, and Glycerin.
Gently heat the mixture to 70°C and stir at a low speed (not exceeding 500 rpm) until everything is dissolved and clear.
Let the mixture cool down to below 50°C.
The formula can still accommodate fragrance or essential oils as usual.

Remember to test the modified formula in a small batch first to ensure it meets your expectations for foam and skin feel.
