Emulsifier A-105 (CAS No.: 9004-96-0) is a pale yellow to yellow viscous liquid, produced by the addition reaction of nonylphenol and ethylene oxide. The synergistic effect of ether bonds and hydroxyl groups in its molecular structure imparts excellent interfacial activity, enabling rapid adsorption at the oil-water interface and significantly reducing interfacial tension, thus providing stable performance in various systems.
The most prominent advantage of this product is its "multi-functionality in a single agent": it can serve as an efficient emulsifier to stably disperse oil-phase components in water, while its excellent wetting and spreading ability accelerates liquid penetration on solid surfaces. Its dispersion performance effectively prevents agglomeration and sedimentation of solid particles, and its detergency shows outstanding removal of oil stains, waxes, and organic residues. Moreover, under a wide pH range and high hardness water conditions, A-105 maintains stable performance, which is particularly important in complex industrial conditions.
In terms of compatibility, A-105 can be flexibly compounded with anionic, cationic, and other non-ionic surfactants to achieve synergistic effects, making it a highly flexible basic raw material for formulation engineers.

Based on the comprehensive performance characteristics of A-105, its typical application scenarios cover six major fields:
Eye protection is the top priority: This product can cause severe eye irritation or even corneal damage. Always wear chemical safety goggles when handling. In case of eye contact, immediately hold eyelids open and rinse with flowing clean water or saline solution for 15-20 minutes. Do not rub eyes and seek medical attention promptly.
Environmental disposal requirements: A-105 is toxic to aquatic life (fish LC₅₀ 1-10 mg/L, daphnia EC₅₀ 1-10 mg/L) and has slow biodegradation. Do not discharge waste liquid containing this product into sewers or natural water bodies. Waste materials must be disposed of as hazardous waste by qualified units.
Storage points: Store in a cool, dry, well-ventilated area. Temperature should not exceed 40°C. Keep away from fire sources and high-temperature areas. Seal containers promptly after use to prevent moisture absorption and contamination. Store separately from incompatible substances such as strong oxidizers, strong acids, and strong bases.
