OA-12/Lauryl Dimethyl Amine Oxide/Ammonyxao/Cationic surfactant

OA-12 is a versatile amphoteric surfactant widely used in household and personal care products due to its unique properties. Below is a detailed breakdown of its functions:

• pH Adaptability:

• Nonionic at pH >7 (compatible with anionic surfactants).

• Cationic at pH <3 (enhances antimicrobial efficacy in disinfectants).

• Low Irritation:

• Draize test scores <1 (vs. SLES ~5), ideal for baby/mild products.

• Hard Water Tolerance:

• Maintains foaming in high Ca²⁺/Mg²⁺ water (up to 15% NaCl).

• Foam Stability (0.1% solution, 25°C):

• Initial foam height: 195 mm (vs. 180 mm for SLES alone).

• 5-min retention: 85% (vs. 70% for SLES).

• Mildness (in vitro EpiSkin test):

• Cell viability >90% at 1% OA-12 (vs. ~50% for SLES at same concentration).

• Approvals: EU CosIng, FDA 21 CFR §172.710, China INCI.

• Ecotoxicity:

• Biodegradability: >90% (OECD 301B).

• LC50 (Daphnia magna): >100 mg/L (low aquatic toxicity).

• Sulfate-Free Formulations: Replaces SLES in "no-poo" products with CAPB.

• Green Chemistry: Bio-based OA-12 variants (e.g., palm-free) gaining traction.

Pro Tip: For cost-effective formulations, blend OA-12 with sodium lauryl sulfoacetate (SLSA) to balance mildness and cleaning power.

OA-12’s multifunctionality makes it indispensable in daily chemicals, bridging performance and safety. Need formulation optimizations? Ask away!
