Clarifying Usage Percentage for Liquid Cocamidopropyl Betaine (30% Active)
Question
When using liquid Cocamidopropyl Betaine (Coco Betaine) which is sold as a solution with 30% active matter, does the recommended usage percentage refer to the percentage of the liquid product itself or the percentage of the pure active matter in the final formulation?
For example, if the recommended usage is 10%, does this mean 10% of the liquid product or 10% active matter?
Answer
Based on the conversation and the staff's confirmation, the usage rate percentages provided for Cocamidopropyl Betaine (Coco Betaine), which is sold as a liquid with 30% active matter, refer to the percentage of the liquid product to be used in your formulation.
For example, if the recommended usage rate is 10%, you should add 10g of the liquid Cocamidopropyl Betaine (30% active matter) per 100g of your final formula. This means your final formula will contain 10% of the liquid product, which is equivalent to 10% * 30% = 3% active matter from Cocamidopropyl Betaine.
Using the liquid product "pure" (100% concentration of the liquid product) would indeed result in a formula with 30% active matter, but the typical usage rates are much lower and refer to the liquid product itself.
