1. Basic Information
MES, short for Fatty Acid Methyl Ester Sulfonate, is a promising anionic surfactant. Its CAS No. is 93348 - 22 - 2 (for the typical sodium - based form). Derived from renewable natural resources like palm oil, it stands out as an eco - friendly and sustainable ingredient for detergents.

Physical Appearance
MES - 86 (Pure Powder):
Presents as a white or light yellow powder at 25°C, with a fine texture that ensures easy dispersion in detergent formulations
MES - 86 (Flake):
Appears as a light yellow flake, offering convenience in handling and storage, and also facilitating uniform mixing during production
MES - 86 Powder (15% Zeolite): Exhibits a white or light yellow powder form, integrating the properties of MES with the advantages of zeolite, which is beneficial for certain detergent applications.
2. Key Properties
Biodegradability: Fully biodegradable, aligning with green chemistry principles and reducing environmental impact after use.
Detergency: Exhibits strong cleaning power even at low concentrations. In hard water conditions, its detergency outperforms many traditional surfactants (e.g., linear alkylbenzene sulfonate - LAS). Tests show MES - formulated detergents can achieve comparable or better stain removal with less surfactant dosage.
Hard Water Tolerance: Superior ability to work in hard water. It resists forming insoluble complexes with calcium/magnesium ions, maintaining effective cleaning without excessive limescale residues.
Mildness: Low irritation to skin and fabrics. Gentler than alkylbenzene sulfonic acid, suitable for formulating personal care detergents (shampoos, body washes) and household cleaners.
Compatibility: Works well with other surfactants (e.g., LAS, AES, AOS) and enzymes. Enhances formulation stability and synergistically boosts overall cleaning performance.
3.Performance Advantages
High Detergency: Compared with traditional anionic surfactants, MES achieves the same level of cleaning power with a lower dosage. This not only reduces the amount of organic matter used in detergents but also contributes to a decrease in carbon dioxide emissions during the production and use of detergents, making it an environmentally - friendly option.
Excellent Hard - Water Resistance: MES shows outstanding performance in hard - water conditions. It can effectively complex with calcium and magnesium ions in hard water, preventing the formation of soap scum and maintaining high - quality cleaning effects. This property makes detergents formulated with MES suitable for use in areas with hard water supplies.
Low Skin Irritation: With its mild nature, MES causes minimal irritation to the skin. This makes it an ideal choice for detergents used in applications where skin contact is frequent, such as hand - wash detergents and baby - care detergents. It provides a safe and comfortable cleaning experience for consumers.
Biodegradability: As a surfactant derived from renewable resources, MES is biodegradable. It can be decomposed by microorganisms in the environment, reducing the potential for environmental pollution and aligning with the requirements of sustainable development.
4. Applications in Detergents
Laundry Detergents:
Powder Detergents: Improves anti - hard - water performance, reduces the need for softening agents (e.g., zeolites), and minimizes inorganic salt deposits on clothes. Enables softer, less graying fabric after washing. Ideal for concentrated powder formulas, solving drying/forming challenges of traditional concentrates.
Liquid Detergents: When compounded with polyols, oleic acid, etc., it solves low - temperature stability issues. Suitable for concentrated liquid detergents, delivering efficient cleaning in various water qualities.
Personal Care Cleansers: Used in shampoos, body washes, hand soaps. Its mildness and foaming properties (moderate, easy - to - rinse bubbles) provide a comfortable user experience.
Industrial & Specialty Cleaners: Applied in leather degreasing, wool washing, ore flotation auxiliaries, etc., leveraging its emulsifying, dispersing, and cleaning capabilities.
5. Packaging and Storage
Packaging: MES is usually packaged in multi - layer kraft paper bags with inner plastic liners for the powder and flake forms. This packaging provides good protection against moisture, dust, and other contaminants, ensuring the quality of the product during storage and transportation.
Storage: It should be stored in a cool, dry, and well - ventilated warehouse. Avoid direct sunlight, high temperatures, and humidity to prevent the product from deteriorating, hydrolyzing (especially for the powder form), or losing its performance characteristics.
