Adjusting Your Formula for More and Finer Foam

To get more foam and finer bubbles in your cleansing formula, you can adjust the types and ratios of the surfactants used. Your current formula contains three main surfactants: Cond-Foam (Sodium Lauroyl Sarcosinate), Coco Betaine (Cocamidopropyl Betaine), and Lauryl Glucoside.

Here's how each surfactant contributes to the foam:

• Cond-Foam (Sodium Lauroyl Sarcosinate): This provides good foaming and has a conditioning effect. It performs best in the pH range of 5-6.
• Coco Betaine (Cocamidopropyl Betaine): This is a gentle co-surfactant that helps create smooth and fine foam. It provides the most foam at pH 7.0.
• Lauryl Glucoside: This is a gentle non-ionic surfactant but provides less foam when used alone. It works well in combination with other foaming agents.

To increase the overall foam and improve its fineness, you can increase the total concentration of surfactants and adjust their ratios to favor those known for better foam quality, specifically Cond-Foam and Coco Betaine.

Proposed Adjustment:

Consider increasing the percentage of Cond-Foam and Coco Betaine. For example, you could try the following adjustment:

• Water: 60.2%
• Glycerin: 3%
• Cond-Foam: 12% (Increased from 10%)
• Coco Betaine: 8% (Increased from 5%)
• Lauryl Glucoside: 10% (Kept the same)
• Sugar Thick: 1.5%
• Fragrance: 0.5%
• Flora Solve: 1%
• Color: 0.1%
• Microcare PHC: 0.7%

This increases the total surfactant concentration from 25% to 30% and shifts the balance towards Cond-Foam and Coco Betaine, which should result in more abundant and finer foam.

Important Consideration: pH Level

The pH of your final formula significantly impacts surfactant performance. Cond-Foam works best at pH 5-6, while Coco Betaine is optimal at pH 7. Since you are using both, aiming for a pH in the range of 5.5 to 6.5 might provide a good balance for both surfactants to contribute effectively to the foam.

Other ingredients like Sugar Thick act as a thickener and should not negatively affect foam. Flora Solve helps solubilize the fragrance, Glycerin is a humectant, and Microcare PHC is a preservative.
