LMEO-18

Chemical composition: long-chain carboxylic acid ester and ethylene oxide adduct

Content and appearance: 75% liquid

Characteristic:

        Long-chain carboxylate polyoxyethylene LMEO-18, the appearance is a light yellow viscous liquid, the effective active substance content is about 75%; it is a new type of non-ionic surfactant with low foam performance, excellent emulsification, dispersion, moisturizing Wet, clean and other superior performance;

       LMEO is an 18-carbon fatty acid ester with an ester-based molecular structure similar to that of oil and wax. According to the principle of similar miscibility, it has a strong ability to dissolve and remove oil, mineral oil, and paraffin wax; it has a more reasonable dual Bond structure, better dispersion and removal of lipids; high temperature and low temperature conditions have the same excellent detergency, oil solubilization, dispersibility, and wettability.

Technical Index：

General properties:

Solubility: soluble in water, ethanol, ethylene glycol, etc.

Chemical properties: 10% aqueous solution is clear and transparent at 25°C. It is stable to acid, alkali solution and hard water. It has good emulsifying and dispersing properties.

Product Features:

1) The molecular formula has an ester group and a double bond structure, which is similar to the structure of oil and wax;

2) It has a high cloud point, the cloud point is above 100 degrees, it has excellent performance in high temperature process, and has low foam and high cleaning ability;

3) Good fluidity at low temperature, fluidity at zero temperature, excellent performance at low temperature

4) With strong dispersing performance, it can disperse oil, wax, dirt, etc. in the working fluid to prevent dirt and anti-contamination, so it is also suitable for degreasing and wax removal under low temperature conditions, and can make up for the weakening of the dispersion force of the working fluid caused by low temperature The resulting cleaning ability is reduced.

5) Good biodegradability, environmentally friendly, non-irritating to the skin; LMEO is an excellent penetrating, emulsifying agent, wetting and cleaning agent, and does not contain APEO, has good biodegradability and is environmentally friendly;

6) It has good compatibility and can be compounded with other types of anionic, nonionic, and cationic surfactants. It has outstanding synergistic effects, can greatly reduce the consumption of additives, and achieve good cost performance; it can improve the additives used in paints. Thickener efficacy and improved flushing of solvent-based systems.

7) Low-foaming, high-efficiency, easy-to-rinse, low skin irritation, low ecotoxicity, and strong oil solubilizing power

8) Disadvantage: Because it is non-ionic, the strong alkali resistance is slightly poor

Comparison:

1. Degreasing property: LMEO-18 degreasing power is 1.5 times that of isomerized alcohol, nonylphenol and fatty alcohol polyoxyethylene ether, and 2.5 times that of triethanolamine oleic acid soap.

2. Wax removal: LMEO-18 wax removal power is 1.6 times that of isomeric alcohols, nonylphenols, and fatty alcohol polyoxyethylene ethers, and 1.4 times that of triethanolamine oleic acid soap;

       LMEO-18 is used as refining agent for degreasing and waxing of knitted fabrics, refining agent for printing and dyeing knitted fabrics, chemical fiber degreasing agent, high-efficiency degreasing emulsifier, leather degreasing agent, metal degreasing and degreasing agent, civil detergent, kitchen utensil cleaning Agent, used as industrial emulsifier and metal cleaning agent, etc.

     The superior performance of LMEO-18 has been widely used in daily chemical washing, textile printing and dyeing, leather auxiliaries, surface treatment, paint coatings, paper making, pesticides, plastics, mineral processing and oil field mining and other fields.
