Cocamidopropyl Betaine (CAPB), particularly the CAPB-35 grade, stands out as a widely recognized and highly effective ampholytic surfactant in the personal care industry. Derived from natural coconut oil combined with dimethylaminopropylamine, this ingredient is a sticky, light yellow liquid known for its versatile applications and beneficial properties. Its origin from renewable resources like coconut oil makes it an attractive option for formulators seeking more natural or bio-based ingredients.

CAPB functions by reducing the surface tension of water, allowing dirt, oils, and impurities to be lifted away from skin and hair surfaces and easily rinsed off. Beyond its primary cleansing ability, it is highly valued for its exceptional foaming performance. It produces a rich, dense, and stable lather, even in the presence of oils or hard water, enhancing the sensory experience of cleansing products.

One of the most significant advantages of CAPB is its mildness. Compared to anionic surfactants like sulfates, CAPB is considerably less irritating to the skin and eyes. This makes it a preferred choice for formulating 'tear-free' baby shampoos, gentle facial cleansers, sensitive skin body washes, and mild hair care products. Its ampholytic nature means it can exhibit anionic, cationic, or nonionic characteristics depending on the pH of the formulation, contributing to its compatibility with a wide range of other surfactants and ingredients.

CAPB-35 is typically supplied as an aqueous solution with an active matter content around 28-32% and a total solid content around 34-36%. Key specifications often include a pH value in the slightly acidic to neutral range (typically 4.0-6.0 for a 10% solution) and low levels of impurities like sodium chloride and free amine. These specifications are critical for ensuring product quality, stability, and performance in final formulations.

Its applications span a broad spectrum within personal care and household products. It is a staple ingredient in shampoos, conditioners, body washes, liquid soaps, facial cleansers, bubble baths, and even some household cleaning agents where mildness and good foaming are desired. Its ability to improve viscosity, boost foam, and reduce the irritation potential of anionic surfactants makes it an invaluable co-surfactant.

As consumer demand for gentle, sulfate-free, and naturally derived products continues to grow, the importance of ingredients like CAPB-35 increases. Formulators rely on its consistent quality and performance to meet these market needs. Sourcing high-quality CAPB-35 is crucial for product efficacy and safety.

For businesses looking to procure this essential ingredient, finding a reliable manufacturer and supplier is paramount. The price of CAPB-35 can vary based on factors like purity, concentration, order volume, and market conditions. When considering where to buy or purchase, potential buyers should inquire about production capacity, quality control procedures, packaging options (such as 200kg drums or 1000kg IBC tanks), and logistics. Requesting samples before committing to a large purchase is a common and recommended practice to verify quality and suitability for specific applications. A knowledgeable supplier can also provide technical support and guidance on formulation. Ensuring the product meets international standards and relevant cosmetic regulations is also a key step in the procurement process for any serious manufacturer of finished goods.
