Lauryl Alcohol Polyoxyethylene Ether LAE-9 is a high-performance nonionic surfactant, with core features including efficient emulsification and solubilization capabilities, broad chemical compatibility, and excellent multifunctionality in wetting, penetration, and dispersion. \n\nDetailed Description
\n
Lauryl Alcohol Polyoxyethylene Ether LAE-9 (Chemical name: PEG-9 Laurate, CAS: 9004-81-3) is a classic nonionic surfactant provided by Guoli Chemical. Its primary feature lies in its outstanding emulsifying ability, especially adept at constructing stable oil-in-water (O/W) formula systems, while also offering excellent solubilization effects, significantly enhancing the solubility of oily components in water-based products and the clarity of the finished product. \n\n
The second significant feature of this product is its excellent chemical stability and broad compatibility with other ingredients. It remains stable in acid, alkali, and high-concentration hard water environments, and can be well compounded with anionic, cationic, and other nonionic surfactants. This allows LAE-9 to be flexibly applied in various complex formula systems from acidic to highly alkaline, greatly expanding its application range. \n\n
In addition, LAE-9 integrates multiple auxiliary functions such as wetting, penetration, and dispersion. It effectively reduces the surface tension of the system, promoting rapid spreading and penetration of liquids on solid surfaces such as textiles, metals, and leather, which is crucial for improving the efficiency and uniformity of industrial processes like washing, dyeing, and fatliquoring. \n\n

Application Suggestions
\n
Based on its HLB value (13.6) and multifunctional characteristics, LAE-9 is used as a core auxiliary agent in multiple industries:
\n
\n - Daily Chemical Products: Used as an O/W emulsifier in creams and lotions, and as a solubilizer for fragrances and oily active ingredients in shampoos and lotions, improving product transparency and stable skin feel.
\n - Detergents: In household laundry detergents, dishwashing liquids, and industrial heavy-duty cleaning formulations, it acts as a detergency enhancing component, demonstrating excellent emulsification and removal ability for oil stains and sebum.
\n - Textiles and Leather: As a leveling agent to promote uniform dye uptake; as a softening and antistatic agent to improve fabric hand feel; as an emulsifying and dispersing carrier for fatliquors, enabling uniform absorption of oils by leather and enhancing softness.
\n - Agrochemicals and Metalworking: As an efficient and environmentally friendly emulsifier in pesticide emulsifiable concentrates and microemulsions; providing lubrication, cooling, and rust prevention functions in metal cutting and grinding fluids.

Precautions
\n
When using this product, safety operating procedures must be followed:
\n
\n - Hazards: Harmful if swallowed (H302), causes skin irritation (H315), causes serious eye damage (H318), and is very toxic to aquatic life with long-lasting effects (H410).
\n - Personal Protection: Wear chemical safety goggles, impermeable gloves, and protective clothing during operation. Avoid contact with eyes and skin.
\n - Environmental Protection: Do not discharge the product directly into water bodies, sewers, or soil. Spills should be absorbed with inert material and disposed of in accordance with hazardous waste regulations.
\n - First Aid: In case of skin contact, wash immediately with plenty of soap and water. In case of eye contact, flush with water for several minutes and seek medical attention. If swallowed, do not induce vomiting; rinse mouth with water and seek medical advice.
