1. Basic Information
- Chemical Name: Cetrimonium Methyl Sulfate
- Common Abbreviation: 1631MS
- Molecular Formula: C₂₀H₄₅NO₄S
- Molecular Weight: 409.64 g/mol
2. Physical and Chemical Properties
- Appearance: At room temperature, it appears as a white to slightly yellowish, semi - solid or paste - like substance. This characteristic appearance is suitable for various applications where a semi - solid form can be easily incorporated into different formulations.
- Solubility: It has good solubility in water, ethanol, and some polar organic solvents. In water, it can form clear or slightly opalescent solutions. For example, in a 1% aqueous solution, it disperses well, and the solution shows good fluidity. This solubility property makes it versatile in applications that require mixing with different liquid media.
- pH Sensitivity: In a 1% aqueous solution, the pH value typically ranges from 6.0 to 8.0. This near - neutral pH range indicates its stability in a relatively wide pH environment, which is beneficial for applications where it needs to co - exist with other substances without significant pH - induced reactions.
- Melting Point and Boiling Point: The melting point of 1631MS - 70% is around [insert specific melting point if available] °C. Its relatively high melting point compared to some common surfactants contributes to its stability in solid - state or semi - solid - state applications. As for the boiling point, due to its decomposition at high temperatures before reaching a typical boiling point, it is not commonly reported in the traditional sense.
3. Product Specifications
- Active Ingredient Content: The product is characterized by a 70.00 ± 2.00% content of cetrimonium methyl sulfate. This high and precisely controlled active ingredient concentration ensures reliable performance in various applications. The remaining 30% mainly consists of solvents and minor impurities within the allowable range, which do not significantly affect the overall performance of the product.
- Impurity Limits: The content of free amines is strictly controlled to be ≤ 2.0%. High levels of free amines can affect the product's odor, stability, and reactivity in some applications. Other potential impurities, such as unreacted starting materials or by - products from the synthesis process, are also maintained at very low levels to guarantee product quality.
- Packaging: It is usually packaged in 50 - kg plastic drums. The plastic drums are made of high - density polyethylene (HDPE), which provides good chemical resistance, preventing any interaction between the product and the packaging material. This packaging size is convenient for handling, storage, and transportation, whether for small - scale users or large - scale industrial applications. Customized packaging options may also be available upon request, such as larger - sized containers for bulk orders or smaller sample - sized packages for product evaluation.
4. Product Performance
- Excellent Surfactant Properties: 1631MS - 70% is a high - quality cationic surfactant. It has a strong ability to reduce the surface tension between two immiscible phases, such as oil and water. In emulsion - based applications, it can effectively emulsify oils, waxes, and other hydrophobic substances in an aqueous medium. For example, in the production of emulsion - type cosmetic products like lotions and creams, it helps to form stable emulsions with small droplet sizes, resulting in a smooth and homogeneous texture.
- Softening and Antistatic Effects: In the textile and paper industries, it exhibits remarkable softening properties. When applied to fabrics, it can penetrate into the fiber structure, making the fabric feel softer and more comfortable. Its antistatic property is also significant. In synthetic fiber processing, static electricity can cause problems such as fiber entanglement and difficulty in handling. The positive charge of 1631MS - 70% can neutralize the negative charge on the fiber surface, reducing static electricity and improving the processing efficiency.
- Good Compatibility: It can be well - compatible with cationic, non - ionic, and many amphoteric surfactants. This compatibility allows for the formulation of complex surfactant systems in various applications. For instance, in detergent formulations, it can be combined with other surfactants to enhance the overall cleaning performance, including the removal of different types of stains from fabrics.
- Chemical Stability: It has good chemical stability, being resistant to heat, light, and a wide range of pH conditions. This stability makes it suitable for applications that may encounter harsh environmental factors. In industrial applications, such as in the formulation of products for high - temperature processing or long - term storage, its stability ensures that the product's performance remains consistent over time.
5. Application Fields
- Cosmetics and Personal Care:
- Hair Care Products: It is widely used in hair conditioners and hair styling products. In hair conditioners, it helps to smooth the hair cuticle, reduce tangling, and improve hair manageability. It also imparts a soft and shiny appearance to the hair. In hair styling products like gels and mousses, it can enhance the product's hold and provide antistatic properties, preventing flyaways.
- Skin Care Products: In some skin - care creams and lotions, it can act as an emulsifier and a skin - conditioning agent. As an emulsifier, it helps to create stable emulsions of oil - in - water or water - in - oil types. As a skin - conditioning agent, it can improve the skin's feel, making it smoother and more hydrated.
- Industrial Applications:
- Textile Industry: As a fabric softener and antistatic agent, it is added during the textile finishing process. It improves the quality and comfort of textiles, making them more appealing to consumers. In addition, it can also be used in textile dyeing processes to help with the dispersion of dyes and improve color fastness.
- Paper Industry: In the paper - making process, it can be used as a paper softening agent and a wet - strength agent. As a softening agent, it improves the hand - feel of paper products, making them more suitable for applications such as facial tissues and toilet paper. As a wet - strength agent, it enhances the strength of paper when it is wet, which is important for products like paper towels and some packaging papers.
- Water Treatment: It can be used as a flocculant in water treatment processes. In wastewater treatment, it can help to coagulate suspended particles, such as organic matter and colloidal substances, making them easier to remove through sedimentation or filtration. This application helps to improve water quality and meet environmental standards.
- Agriculture: In some agricultural formulations, such as pesticide emulsions, it can be used as an emulsifier. It helps to disperse pesticides evenly in water, improving their efficacy and ensuring uniform application on crops.
- Biomedical Research: In certain laboratory applications, it may be used as a surfactant in cell culture media or in the extraction and purification of biological macromolecules. Its ability to interact with biological membranes and proteins can be exploited for various research purposes.
6. Storage and Transportation
- Storage Conditions: Store in a cool, dry, and well - ventilated area. Avoid direct sunlight and high - temperature environments, as excessive heat can potentially cause the product to degrade or change its physical state. The recommended storage temperature is between 5 °C and 30 °C. Keep the product away from strong oxidizing agents and incompatible substances to prevent chemical reactions.
- Transportation Precautions: During transportation, ensure that the packaging is intact and not damaged. The 50 - kg plastic drums should be properly secured to prevent tipping or leakage. For long - distance transportation, consider using temperature - controlled vehicles if the product is likely to be exposed to extreme temperatures. Follow all relevant regulations for the transportation of chemical products to ensure safe delivery.
