The product we are introducing here is high - quality p - Hydroxybenzoic acid with the CAS number 99 - 96 - 7. It is a white crystalline powder with a molecular formula of C7H6O3 and a molecular weight of 138.12 g/mol. The melting point of p - Hydroxybenzoic acid ranges from 213 - 217 °C. It is sparingly soluble in cold water but more soluble in hot water, alcohol, and ether. This product is carefully manufactured to meet high - quality standards and is available at the best price in the market.
1. **Cosmetics and Personal Care Products**: p - Hydroxybenzoic acid is widely used as a preservative in cosmetics and personal care items such as creams, lotions, and shampoos. It can effectively inhibit the growth of bacteria, molds, and yeasts, extending the shelf - life of these products and ensuring product safety.
2. **Pharmaceutical Industry**: In the pharmaceutical field, it can be used as an intermediate for the synthesis of various drugs. For example, it can be used in the production of some local anesthetics and antibacterial drugs.
3. **Food Industry**: Although its use in food is more restricted compared to other applications, it can still be used as a food preservative in some regions. It helps prevent food spoilage and maintain food quality.
1. **Cosmetics and Personal Care Products**: When using p - Hydroxybenzoic acid in cosmetics, it is usually added at the appropriate stage of the production process. First, it needs to be dissolved in a suitable solvent such as alcohol or propylene glycol. The recommended concentration is generally between 0.1% - 0.5% depending on the type of product and the expected level of preservation. After dissolution, it should be mixed evenly with other ingredients of the cosmetic formulation.
2. **Pharmaceutical Synthesis**: In pharmaceutical synthesis, p - Hydroxybenzoic acid is used as a raw material. The reaction conditions need to be carefully controlled according to the specific synthesis route. Appropriate catalysts, solvents, and reaction temperatures should be selected to ensure the efficiency and yield of the reaction.
3. **Food Industry**: If used in food, it should be added in strict accordance with relevant food safety regulations. The amount added should be accurately measured to ensure that it does not exceed the permitted limits. It is often added during the food processing stage and thoroughly mixed with the food ingredients.
1. **Cosmetics Case**: A well - known cosmetics brand was facing the problem of short - shelf life of its moisturizing cream due to microbial growth. After adding p - Hydroxybenzoic acid at a concentration of 0.3%, the shelf - life of the cream was extended from 6 months to 12 months. Consumers reported fewer complaints about product spoilage, and the brand's reputation for product quality was enhanced.
2. **Pharmaceutical Case**: A pharmaceutical company was developing a new antibacterial drug. By using p - Hydroxybenzoic acid as an intermediate in the synthesis process, they were able to achieve a high - yield synthesis. The new drug showed excellent antibacterial activity in pre - clinical trials, and the use of this high - quality p - Hydroxybenzoic acid contributed to the success of the drug development project.
3. **Food Case**: A small - scale food producer of fruit jams was struggling with mold growth in their products. After adding p - Hydroxybenzoic acid within the permitted limits, the jams remained mold - free for a longer period. This not only reduced the producer's product waste but also increased customer satisfaction.
