    Product Description

    Cocamidopropyl Betaine (CAPB), CAS 61789-40-0 and EC 263-058-8, is an amphoteric surfactant derived from coconut fatty acids. Powder grades are used in solid and concentrated personal-care and cleaning formulations.

    Synonyms: CAPB; Cocoamidopropyl betaine; CADG; Cocamidopropyl dimethyl glycine.

    CAS: 61789-40-0.

    CAPB comprises fatty-acyl homologues derived from coconut fatty acids. Their proportions depend on the raw material and grade, so the commercial product has no single fixed molecular formula or molecular weight.

    EC number: 263-058-8.

    Powder grades concentrate CAPB for dry-blend and low-water formulations. Active matter, total solids and sodium chloride are distinct specification items; a solids result alone does not establish the active surfactant content.

    pH is reported for an aqueous solution at a stated concentration and temperature. Water content and sodium chloride limits are specified for the selected grade; the same limits do not apply to every CAPB powder.

    Appearance, solution color and dissolution behavior are grade-specific. Color results require a stated dilution and scale; Hazen/APHA and Gardner values should not be compared as identical numbers.

    It is used as a mild secondary surfactant in shampoos, 2-in-1 products, body wash, shower gel, liquid soap, facial cleansers, micellar products and baby shampoos; it boosts foam richness and stability, builds viscosity and reduces irritation from primary anionic surfactants such as SLES or SLS.

    It is also used in dishwashing liquids, foam cleaners, household surface and bathroom cleaners, and high-foam car-wash products.

    It is used in industrial detergents and degreasers, textile and leather auxiliaries, and as a wetting agent in certain agricultural or specialty formulations.

    For personal-care grades, quality control includes residual DMAPA and amidoamine, as well as active matter, water, salt and any agreed microbial limits. An amine-value result is not a compound-specific measurement of both residues; impurity results are reported with the test method and reporting limit.

    Keep the powder dry in tightly closed, moisture-protected containers. Storage temperature, incompatible materials and handling controls follow the supplied grade’s SDS; use suitable dust control and protective equipment.

    Confirm the current product-specific specification.

    Confirm packaging with the requested quantity and destination requirements.

    COA (Certificate of Analysis), TDS (Technical Data Sheet) and SDS (Safety Data Sheet) are available for the supplied grade. The TDS states the specification and test conditions; the COA reports batch results, and the SDS covers safe handling.

    For an RFQ, state the intended use, required specification, quantity, packaging, destination and document needs.

    FAQ - Technical & Supply Chain

    • Q:

      What is Cocamidopropyl Betaine Powder CAS 61789-40-0?

      A: Cocamidopropyl Betaine Powder CAS 61789-40-0 is a coconut-derived amphoteric surfactant supplied as a high-active solid. Its INCI name is Cocamidopropyl Betaine, and it is commonly used in concentrated solid cleansing and dry-blend formulations.
    • Q:

      How does the powder form differ from liquid Cocamidopropyl Betaine?

      A: Powder grades introduce less water than aqueous CAPB grades and are useful in solid or low-water formulations. Active matter, water and salt still vary by grade. Formulation dosage is based on active content and composition, so a liquid grade cannot be replaced by powder on an equal-mass basis.
    • Q:

      Is Cocamidopropyl Betaine compatible with anionic surfactants?

      A: Yes. Cocamidopropyl Betaine is amphoteric and works well with anionic surfactants such as SLES and SLS. This combination improves foam quality, viscosity building and mildness while reducing irritation in personal-care and cleaning products.
    • Q:

      What applications are suitable for Cocamidopropyl Betaine Powder CAS 61789-40-0?

      A: It is suitable for solid shampoo bars, facial cleansers, body washes, baby-care products, hand soaps, foaming toilet blocks and high-end household or industrial cleaners. It is especially useful where a mild amphoteric surfactant is needed in a dry or concentrated system.
    • Q:

      What key specifications should be checked before ordering?

      A: Active matter, total solids, sodium chloride, water and pH under defined test conditions help compare grades. For personal-care applications, residual DMAPA and amidoamine need compound-specific results and reporting limits. Specifications and impurity results are available with the grade-specific COA and TDS.
    • Q:

      How should Cocamidopropyl Betaine Powder be stored and handled?

      A: Store it in tightly closed, moisture-protected containers in a cool, dry area away from direct sunlight and strong oxidizers. Use dust-control measures and suitable PPE during weighing, transfer and processing.
