It has a melting point in the range of 77 - 79°C and is sparingly soluble in water but soluble in organic solvents such as ethanol and acetone. This product is factory - supplied at the best price, ensuring high - quality and cost - effective solutions for customers.
1. **Cosmetics and Personal Care Products**: Chlorphenesin is widely used as a preservative in cosmetics and personal care products. It has excellent antibacterial and antifungal properties, which can effectively extend the shelf life of products such as creams, lotions, shampoos, and conditioners. It helps to prevent the growth of microorganisms, ensuring the safety and stability of the product during use.
2. **Pharmaceuticals**: In the pharmaceutical industry, Chlorphenesin can be used as an intermediate in the synthesis of some drugs. It also has certain muscle - relaxant properties, which may be used in the development of related therapeutic agents.
3. **Food Industry**: Although its use in the food industry is more restricted, in some cases, Chlorphenesin can be used as a preservative in certain food products under strict regulatory requirements. It can help to maintain the quality and freshness of food.
1. **Cosmetics and Personal Care**: When using Chlorphenesin in cosmetics and personal care formulations, it is usually added at a concentration of 0.1% - 0.5%. First, dissolve the appropriate amount of Chlorphenesin in a suitable organic solvent, such as ethanol. Then, add the solution to the main formulation under stirring conditions at a temperature below 50°C to ensure uniform dispersion. It is important to follow good manufacturing practices and ensure proper mixing to achieve the best preservative effect.
2. **Pharmaceuticals**: In pharmaceutical synthesis, the use of Chlorphenesin should be carried out in accordance with strict chemical reaction procedures. Appropriate reaction conditions, such as temperature, pressure, and reaction time, need to be controlled to ensure the yield and quality of the final product. Professional chemists or technicians should be involved in these operations.
3. **Food Industry**: If used in the food industry, it must comply with relevant food safety regulations. The dosage should be strictly controlled, and appropriate food - grade solvents or carriers may be used for dissolution and dispersion. It is recommended to consult relevant regulatory authorities and follow their guidelines.
1. **Cosmetics Company A**: Company A was facing challenges with microbial contamination in their new lotion product. After adding Chlorphenesin at a concentration of 0.3% to the formulation, the product passed the microbial stability test with flying colors. The lotion could maintain its quality and safety for more than 12 months on the shelf. Customer complaints about product spoilage decreased significantly, and the product's market share increased due to its improved quality and longer shelf life.
2. **Pharmaceutical Research Institution B**: Institution B was conducting research on a new muscle - relaxant drug. Chlorphenesin was used as an important intermediate in the synthesis process. By optimizing the reaction conditions and using high - quality Chlorphenesin, they were able to achieve a high yield of the target compound. The new drug showed promising results in pre - clinical trials, demonstrating the potential of Chlorphenesin in pharmaceutical research.
