CAPB（CAB）30%：Cocamidopropyl Betaine

CAPB 35%: The Versatile Amphoteric Surfactant for Mild and High-Performance Personal Care

CAPB 35% (Cocamidopropyl Betaine) is a high-purity amphoteric surfactant derived from coconut oil, featuring an active matter content of 35%. Renowned for its exceptional mildness and outstanding compatibility, it serves as an indispensable "gentle partner" in personal care formulations, effectively balancing cleansing performance with skin friendliness. Its multifunctional properties make it a cornerstone ingredient for a wide range of products, from daily essentials to specialized sensitive skin solutions.

Validated Mildness and Superior Safety

A key attribute of CAPB 35% is its proven safety profile. It has undergone rigorous testing, including the OECD Test Guideline 404 for ocular irritation, where it achieved a score of ≤2, classifying it as a mild ingredient. This makes it exceptionally suitable for the most delicate formulations, such as baby shampoos, sensitive skin body washes, and facial cleansers. Its amphoteric nature allows it to maintain stability and mildness across a wide pH range, ensuring compatibility with the skin's natural balance.

Synergistic Irritation Reduction and Foam Enhancement

CAPB 35% excels in its ability to modify and improve surfactant systems. When combined with anionic surfactants like SLES (Sodium Laureth Sulfate) at a recommended ratio of 1:3, it demonstrates a powerful synergistic effect. This blend can reduce the potential irritation of SLES by 30% to 50%, significantly enhancing the overall mildness of the final product. Furthermore, CAPB 35% contributes to a superior sensory experience by boosting foam volume and stability. It helps create a dense, creamy, and luxurious lather that rinses off easily without leaving a sticky residue, greatly improving consumer perception.

Inherent Antimicrobial Efficacy

Beyond its primary surfactant functions, CAPB 35% offers valuable secondary benefits as a mild preservative booster. At incorporation levels of ≥0.5%, it exhibits inhibitory effects against common bacteria such as Staphylococcus aureus. This intrinsic activity contributes to the microbial stability of the finished product, aiding in shelf-life extension and supporting the formulation of milder preservation systems.

Strong Environmental Credentials

Aligned with the demand for sustainable ingredients, CAPB 35% demonstrates a favorable environmental profile. It meets the criteria for ready biodegradability as per OECD 301A, achieving a high degradation rate of 98% within just 5 days. Certain grades of CAPB are also available via mass balance approaches under certifications like ISCC PLUS (e.g., utilizing BASF's biomass balance technology), providing a pathway for brands to incorporate renewable carbon content into their formulations and reduce their fossil footprint.

Conclusion

CAPB 35% is a multifunctional and technologically advanced amphoteric surfactant that masterfully combines confirmed mildness, enhanced performance, and modern sustainability. Its role as a foam booster, irritation mitigator, and mildness enhancer makes it an essential component for creating next-generation personal care products that are both effective and gentle for the skin and the environment.
