Dry Shampoo Formulation using Rice Starch

Subject: Dry Shampoo Formula using Rice Starch

Based on the information provided by the staff, a dry shampoo formula using rice starch primarily consists of:

• Powder Base: RiceSorb™ (Rice Starch) (Product ID 648) - This is the main component, making up approximately 95-99% of the formula. It helps absorb oil.
• Anti-Static/Conditioning Agent: Cetrimonium Chloride (Product ID 161) - Used at a very low concentration, typically 0.5-2%. It helps reduce static and provides a smooth feel to the hair. Since it's a liquid, it should be added slowly while blending.
• Color: Iron Oxides or other cosmetic pigments can be added to match hair color. You can blend different shades of pigments to achieve the desired color.

Regarding your specific questions:

1. Ratio: As mentioned above, RiceSorb is 95-99%, and Cetrimonium Chloride is 0.5-2%. The color percentage would depend on the desired intensity, but it would be a small amount relative to the powder base.
2. Other ingredients: The staff's recommendation focuses on these core components (powder base, anti-static, color). Other ingredients were not mentioned as essential for this basic formula.
3. Mixing with baking soda: Baking soda was not included in the components recommended by the staff for this formula.
4. Choosing color: Use cosmetic-grade pigments like Iron Oxides. You can mix different colors (e.g., brown, black, red iron oxides) to create a shade that blends with your hair color.
5. Special blending: This refers to using a high-speed grinder (like the ones linked by the staff, Product IDs 1452 or 735) to ensure all components, especially the liquid Cetrimonium Chloride and the pigments, are thoroughly and evenly dispersed within the fine powder base. This prevents clumping and ensures uniform color distribution.
6. Shop's recommended formula: The staff has provided the general composition and recommended ratios as detailed above. You can purchase the ingredients (RiceSorb, Cetrimonium Chloride, and Iron Oxides/pigments) from the shop to create this formula.
