Why Choose Transfar AAB-35 Capryl/Capramidopropyl Betaine?
Controlled AAB-35 Specification: Transfar AAB-35 is supplied with 29.0-31.0% active content, pH 7.5-8.5, sodium chloride of no more than 6.0% and free amine of no more than 0.5%, supporting consistent technical evaluation and batch review.
Mild Short-Chain Amphoteric Performance: Within Transfar's range of betaine surfactants, AAB-35 combines an octyl/decyl amidopropyl structure with low irritation, softness, antistatic performance and biodegradability. It can be evaluated with other surfactants to balance cleansing, foam, skin feel and formulation compatibility.
AAB-35 vs CAB-35 and LAB-35: AAB-35 uses shorter octyl/decyl hydrophobes, while cab 35 is based on a cocoyl fatty-acid distribution and lab 35 is based on a lauryl amidopropyl structure. Their active content, salt level, foam profile, hydrotropic behavior and viscosity response may differ, so the final grade should be selected through testing in the complete formula.
Cold-Weather Fire-Fighting Foam Applications: Transfar's TDS identifies AAB-35 as suitable for foam extinguishing formulations used in cold seasons or high-cold areas. The finished formulation must still be validated for storage temperature, foam expansion, drainage, fire performance, material compatibility and the standards required by the destination market.
Bulk Purchasing Information: Packaging type, net weight, MOQ, sample availability, lead time and container loading are not currently displayed and should be confirmed for each order. Buyers may request the TDS, SDS and batch COA for technical and quality review.
CTA: Send your application, required quantity, destination market, performance target and packaging preference to receive an AAB-35 quotation, sample arrangement and technical document package.
AAB-35 Capryl/Capramidopropyl Betaine FAQs
What is Capryl/Capramidopropyl Betaine AAB-35?
AAB-35 is a liquid amphoteric surfactant with the INCI Name Capryl/Capramidopropyl Betaine and CAS Nos. 73772-46-0 and 73772-45-9. Transfar AAB-35 contains 29.0-31.0% active matter, has a pH of 7.5-8.5 in a 5% aqueous solution, and provides mildness, foamability, softness, antistatic performance and biodegradability.
What is AAB-35 used for?
AAB-35 is used in shampoo, bath liquid, facial cleanser, shaving foam and household detergent. Transfar also identifies it for fire-fighting foam liquid formulations intended for cold-season or high-cold environments. Recommended dosage is 2-12% in shower gel and shampoo and 1-2% in cosmetics, subject to formulation and performance testing.
How is AAB-35 different from CAB-35 and LAB-35?
AAB-35 is based on shorter octyl/decyl amidopropyl groups, CAB-35 uses a cocoyl fatty-acid distribution, and LAB-35 uses a lauryl amidopropyl structure. These differences can affect active content, salt level, foam, hydrotropic behavior and viscosity response. The most suitable grade should be selected by testing the complete formulation.
Can AAB-35 be used in fire-fighting foam for cold climates?
Yes. Transfar's TDS lists AAB-35 for foam extinguishing formulations used in cold seasons or high-cold areas. However, the finished fire-fighting foam must be validated for low-temperature stability, expansion ratio, drainage time, extinguishing performance, material compatibility and the applicable standards of the destination market.
