For formulators in the cosmetic and detergent industries, understanding the specifications of key ingredients like Cocamidopropyl Betaine (CAPB), CAS 61789-40-0, is crucial for achieving optimal product performance and stability. CAPB is an amphoteric surfactant widely recognized for its mildness, excellent foaming characteristics, and viscosity-building properties. Two common concentrations available in the market are 30% and 35% effective content. As a leading manufacturer and supplier, we aim to clarify the differences and help you decide which grade best suits your needs.

Both 30% and 35% Cocamidopropyl Betaine are colorless to light yellow transparent liquids, indicating a high level of purity. The primary distinction lies in the concentration of the active surfactant. The 35% grade contains a higher percentage of CAPB, meaning you might need a slightly lower dosage in your formulation to achieve the same level of performance, such as lather generation or viscosity modification, compared to the 30% grade. This can be a significant consideration for formulators aiming to optimize their cost-in-use.

When deciding whether to buy Cocamidopropyl Betaine at 30% or 35%, consider the following: If your formulation has very tight constraints on active ingredient concentration, or if you need to maximize the contribution of CAPB to properties like conditioning or mildness, the 35% grade might be preferable. Conversely, if your formulation already includes a high level of other surfactants or requires a slightly lower active load for other reasons, the 30% grade could be more suitable. Both grades typically maintain similar specifications for sodium chloride content (≤7.0%) and pH (ranging from 5.0 to 8.0), ensuring broad compatibility in various formulations.

As a reliable supplier from China, we offer both concentrations to cater to diverse formulation requirements. Our consistent production capacity of 3000MT per year ensures that you can purchase Cocamidopropyl Betaine in the required volume, with dependable quality. We understand that making the right choice involves evaluating specific project needs, cost targets, and desired end-product characteristics. We encourage you to consult our technical data sheets and consider requesting samples of both the 30% and 35% grades to conduct your own comparative testing. Partner with us, a trusted manufacturer, to secure the optimal Cocamidopropyl Betaine for your cosmetic and detergent products.
