Ratio of Cocamidopropyl Betaine and Sulfate Free Shampoo Base in Shampoo
Question
What is the ratio of Cocamidopropyl Betaine (Coco Betaine) to Sulfate Free Shampoo Base (pH 7, Clear, Foaming) in a shampoo formulation? How much should they be added together? For example, if 20% of Sulfate Free Shampoo Base (pH 7, Clear, Foaming) is used, what percentage of Cocamidopropyl Betaine (Coco Betaine) should be added?
Answer
Using Cocamidopropyl Betaine with Sulfate Free Shampoo Base
Cocamidopropyl Betaine acts as a co-surfactant when used with the Sulfate Free Shampoo Base (pH 7, Clear, Foaming). It helps to boost foam, improve foam stability, and enhance the mildness of the final product.
If you are using 20% of the Sulfate Free Shampoo Base, a typical starting range for Cocamidopropyl Betaine as a co-surfactant would be around 5-10%.
The exact percentage can be adjusted based on the desired level of foam, mildness, and overall feel of the shampoo. You may need to experiment within this range to find the balance that works best for your formulation.
