Cocamidopropyl Betaine, commonly known as CAPB or CAB, stands as a cornerstone ingredient in the formulation of modern personal care and household cleaning products. As an amphoteric surfactant, it possesses the unique ability to exhibit both positive and negative charges depending on the pH level, offering exceptional versatility and performance benefits. Its chemical structure, with the CAS number 61789-40-0 and chemical formula C19H38N2O3, underpins its efficacy and mild profile, making it indispensable for creating gentle yet effective formulations.

One of the primary reasons for CAPB's widespread adoption is its remarkable mildness. It demonstrates significantly lower irritation potential compared to many other common surfactants, particularly anionic ones. This characteristic makes it an ideal choice for leave-on products and wash-off applications intended for sensitive skin, including baby shampoos, facial cleansers, and intimate washes. Its ability to reduce the overall irritation potential of surfactant blends while maintaining cleaning performance is a key advantage for formulators striving for consumer safety and comfort.

Beyond its mildness, Cocamidopropyl Betaine is highly valued for its excellent foaming properties. It helps to generate rich, dense, and stable lather, which is a desirable attribute in shampoos, body washes, and hand soaps. This robust foam enhances the sensory experience for the user and aids in the distribution and effectiveness of the product. When used in combination with anionic surfactants, CAPB exhibits synergistic effects, boosting foam volume and stability while simultaneously mitigating the anionic surfactant's potential for irritation.

The compatibility of CAPB with other surfactant classes – anionic, cationic, and nonionic – further contributes to its utility. This broad compatibility allows formulators greater flexibility in developing complex formulations with specific performance profiles, whether focusing on cleaning efficacy, conditioning, or aesthetics. It also possesses good conditioning and antistatic properties, particularly beneficial in hair care applications, helping to leave hair feeling soft and manageable.

CAPB also plays a crucial role in adjusting the viscosity of liquid formulations. By interacting with other ingredients, it can help achieve desired product textures, from thin liquids to thicker gels, which is essential for product stability, pourability, and consumer preference. Its stability across a wide pH range means that formulations containing CAPB maintain their integrity and performance under various conditions, offering reliability from manufacturing through to consumer use.

The product is typically supplied as a transparent liquid, ranging from colorless to light yellow, at concentrations often between 30% and 35% active matter. Key specifications include solid content, pH value (typically between 5.0 and 8.0), and limits on impurities such as sodium chloride and free amine. Ensuring strict quality control on these parameters is vital for consistent product performance and safety. Packaging is commonly in 200kg drums or 1000kg IBC tanks, designed for safe storage and transport. When stored in a cool, dry, well-ventilated area away from direct sunlight, it typically has a shelf life of 24 months.

The global demand for high-quality Cocamidopropyl Betaine continues to grow, driven by the expanding personal care market and the increasing consumer preference for gentle, effective, and aesthetically pleasing products. As a critical raw material, its consistent availability and quality are paramount for manufacturers in the cosmetics, detergent, and industrial cleaning sectors.

For companies looking to source this essential ingredient, finding a reliable supplier is crucial. A reputable manufacturer and supplier understands the importance of product purity, consistency, and technical support. When considering a purchase, potential buyers should inquire about detailed specifications, production capacity, and quality assurance processes. Understanding the current market price and logistical capabilities is also key to a successful procurement strategy. Securing a long-term supply requires partnering with a provider capable of meeting demand efficiently and reliably. Information on how to buy or purchase different quantities, whether small samples for testing or large bulk orders, should be readily available to facilitate seamless transactions. Obtaining competitive price quotes is a standard part of the process for any bulk chemical purchase. Selecting a trusted manufacturer and supplier ensures not only access to high-quality Cocamidopropyl Betaine but also supports the integrity and performance of the final consumer products.
