Liquid Body Soap Formulation: Cleansing Effectiveness, Fragrance, and pH Adjustment

Subject: Re: Inquiry about making liquid body soap

Hello,

Regarding the formula you provided for liquid body soap:

• Coco Wash™ (PEG-7 Glyceryl Cocoate) 5%
• Cocamidopropyl Betaine (Coco Betaine) 25%
• Glycerin 5%
• AQUA 60%
• Perfume 5%

This formula may not be suitable for body cleansing as its effectiveness might be too low.

Based on the staff's advice:

• Coco Wash™ is not ideal for body wash; it is more suitable for makeup remover formulas.
• Using only Coco Betaine might not provide sufficient cleansing.
• A high concentration of perfume (5%) requires a solubilizer to prevent separation.

Recommendations for improvement:

1. Remove Coco Wash™ from the formula.
2. Reduce the percentage of Coco Betaine to 15-20%.
3. Add another surfactant with better cleansing performance, such as Clarify-Wash™ (Sodium C14-16 Olefin Sulfonate) at least 5%, to ensure adequate cleansing.
4. For the 5% perfume concentration, you will need a solubilizer like Flora Foam or Flora Solve to help it blend into the formula and prevent separation.
5. To enhance fragrance longevity, consider using fragrance fixatives such as Sugar Fix, Flora Fix, or Last Fix.

Regarding pH adjustment:

• After mixing the formula, measure the pH.
• If the pH is higher than 7, add a small amount of Lactic Acid or Citric Acid to adjust it down to the range of 5-7, which is more suitable for the skin.

Hope this information is helpful.

Thank you.
