LMES

Sodium long chain carboxylate polyoxyethylene sulfonate

Chemical composition: long-chain carboxylate and ethylene oxide addition sulfonate

       Long chain carboxylate sodium polyoxyethylene sulfonate, the appearance is light yellow transparent viscous liquid, it is a new type of surfactant, it is the product of sulfonated LMEO, it is an anionic surfactant with comprehensive and efficient performance, Low foam and alkali resistance, excellent emulsification, dispersion, wetting, cleaning and other superior properties, not only has the characteristics of LMEO's efficient oil and wax removal, but also has high alkali resistance after sulfonation; high temperature and low temperature Conditions have the same excellent detergency, grease solubilization, dispersibility, and wettability.

Technical Index:

General properties: Solubility: Easily soluble in water, ethanol, ethylene glycol, etc.

Chemical properties: 10% aqueous solution is clear and transparent at 25°C. It has excellent alkali resistance, good emulsifying and dispersing properties.

Product Features:

1. Among the anionic surfactants, LMES has the best emulsifying power, the best oil and wax removal effect, and the best cleaning ability.

2. Excellent alkali resistance, no need to compound phosphate esters, high detergency, low foam.

3. LMES has excellent cleaning and decontamination ability with low foam.

4. It has good fluidity at low temperature, and it still has fluidity at minus 2 degrees.

5. Low-foaming, high-efficiency, easy-to-rinse, low skin irritation, low ecotoxicity and strong oil solubilizing ability.

6. Good biodegradability, environmentally friendly, non-irritating to the skin.

7. LMES is an excellent penetrating, emulsifying, wetting and cleaning agent, and does not contain APEO, has good biodegradability and is environmentally friendly.

8. Disadvantage: Due to its high carbon number structure, its permeability is not as good as that of traditional anionic surfactants.

Comparison:

1. LMES can withstand 100℃ hot alkali up to 55g/L, and 30℃ hot alkali can reach 100g/L.

2. The calcium soap dispersibility of LMES is 320ppm, the calcium soap dispersibility of LAS is only 95-100ppm, and the calcium soap dispersibility of AES is 200-210ppm, so the long-chain carboxylate polyoxyethylene sulfonate sodium LMES has excellent Dispersion performance, suitable for cleaning working liquid with small liquor ratio, evenly dispersing dirt in cleaning liquid to prevent anti-contamination.

      LMES 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 and kitchen utensil cleaning agent, Used as industrial emulsifier and metal cleaning agent, etc.; long-chain carboxylate polyoxyethylene sulfonate sodium LMES has superior performance in daily chemical and civil washing, textile printing and dyeing, leather auxiliaries, surface treatment, paint coatings, papermaking, pesticides, plastics It has been widely used in fields such as mineral processing and oil field exploitation.
