Recently, with the continuous upgrading of consumers' demand for "mildness, functionality and environmental friendliness" of daily chemical products, Cocamidopropyl Hydroxysultaine (CAPHS for short) has become a core raw material for mid-to-high-end cleaning and personal care products, thanks to its natural origin, diverse efficacy and excellent compatibility. It has set off an application boom in fields such as personal care and household cleaning. As a new type of amphoteric surfactant, CAPHS perfectly balances cleaning power and mildness, and injects new momentum into the high-quality development of the daily chemical industry by virtue of mature synthesis technology.
Cocamidopropyl Hydroxysultaine (CAS No.: 68139-30-0) is an inner salt-type amphoteric surfactant synthesized from natural coconut oil fatty acids. Its chemical name is N-Cocoylaminopropyl-N,N-dimethyl-2-hydroxy-3-sulfopropylammonium inner salt, with a molecular formula of C₂₀H₄₂N₂O₅S and a molecular weight of 422.62. Its core structure has both cationic and anionic hydrophilic groups, and its unique molecular configuration endows it with mildness, surface activity and conditioning properties. Compared with traditional surfactants, it is more suitable for the formula requirements of current daily chemical products. In terms of product characteristics and production, CAPHS is mostly a colorless to pale yellow transparent liquid at 25℃ with a light odor, a density of 1.18g/cm³ (20℃), and excellent water solubility with a solubility of up to 520g/L. The pH value of its 1% aqueous solution is stably between 5.0 and 7.0, which is close to the pH value of human skin, making it mild and non-irritating.
As a surfactant with multiple advantages, CAPHS has core effects such as mild cleaning, high-efficiency foaming, conditioning and repair, antistatic property, thickening and stabilization. It also has excellent compatibility with anionic, cationic and non-ionic surfactants, featuring strong formula adaptability. Widely used in mid-to-high-end personal care and household cleaning products, it has gained increasing market recognition.
Mild cleaning is one of CAPHS's core advantages. Its amphoteric ionic structure results in extremely low irritation to skin and hair. Compared with traditional soap-based and synthetic surfactants, it can effectively remove dirt and oil without damaging the skin barrier and hair cuticles, reducing discomfort such as dryness, tightness and itching. It is especially suitable for people with sensitive skin, infants and young children, and damaged hair. Added to facial cleansers, body washes and baby care products, it can achieve a "clean yet mild" user experience, solving the industry pain point of traditional cleaning products that "strong cleaning is inevitably irritating".
The high-efficiency foaming and foam stabilization effects endow products with excellent usability. CAPHS can quickly produce fine and dense foam with strong stability that is not easy to dissipate, which can improve the cleaning coverage and user pleasure of cleaning and care products. In shampoos, body washes, bubble baths, hand soaps and other products, an addition amount of 2%-12% can achieve the ideal foaming effect. Meanwhile, the foam is easy to rinse without residue, avoiding skin irritation and hair dryness caused by residue.
Its conditioning, repair and antistatic properties make it stand out in the hair care field. CAPHS molecules can adhere to the hair surface, forming a breathable protective film that fills the damaged parts of hair cuticles, reduces hair friction and split ends, and significantly reduces hair static electricity, preventing dryness, frizz and tangling, making the hair softer and easier to manage. Applied in shampoos, conditioners, hair masks and other products, it can synergize with other nutritional ingredients to enhance repair effects, improving the moisture and luster of damaged hair.
In addition, CAPHS also has excellent thickening and stabilizing effects. It can effectively increase the viscosity of cleaning and care products, improve product texture and fluidity, enhance the stability of the formula system, avoid problems such as stratification and precipitation, reduce the dosage of additives such as preservatives, and further improve product safety. In the field of household detergents, its good hard water resistance and decontamination ability make it applicable to mild laundry detergents, kitchen cleaners and other products. It can maintain stable cleaning efficacy even in hard water environments, and has excellent biodegradability, being friendly to the water environment and conforming to the green cleaning trend.
