Sodium Perborate Tetrahydrate, with the CAS number 10486-00-7, is a white, odorless, crystalline powder. It has a molecular formula of NaBO₃·4H₂O and a molecular weight of approximately 153.86 g/mol. This compound is highly soluble in water, and the solubility increases with temperature. It is stable under normal storage conditions but may decompose when exposed to heat, strong acids, or reducing agents.
The density of Sodium Perborate Tetrahydrate is around 1.73 g/cm³. It is a mild oxidizing agent, which makes it useful in various applications. The product is typically supplied in high - purity form from the factory, ensuring its quality and consistency for different industrial and consumer uses.
1. **Detergent Industry**: Sodium Perborate Tetrahydrate is widely used as a bleaching agent in laundry detergents. It releases active oxygen in solution, which helps to remove stains, whiten fabrics, and brighten colors. It is particularly effective in removing organic stains such as coffee, tea, and fruit juices.
2. **Toothpaste and Oral Hygiene Products**: In the oral care industry, it can be used as a mild abrasive and oxidizing agent. It helps to remove dental plaque and stains, and it also has some antibacterial properties, contributing to better oral health.
3. **Textile Industry**: It is used for bleaching textiles, especially natural fibers like cotton and linen. It can achieve a high level of whiteness without causing excessive damage to the fabric compared to some other bleaching agents.
4. **Disinfectant and Sanitizer**: Due to its oxidizing properties, it can be used as a disinfectant in various settings, such as in swimming pools, water treatment, and surface cleaning to kill bacteria and viruses.
**In Laundry Detergents**: Add the appropriate amount of detergent containing Sodium Perborate Tetrahydrate to the washing machine according to the load size and the degree of soiling. For heavily soiled clothes, a higher concentration may be required. The optimal washing temperature is usually between 40 - 60°C, as the compound releases active oxygen more efficiently at these temperatures.
**In Toothpaste**: When using toothpaste with Sodium Perborate Tetrahydrate, follow the normal tooth - brushing routine. Apply a small amount of toothpaste to the toothbrush and brush your teeth for at least two minutes, twice a day.
**In Textile Bleaching**: Prepare a bleaching solution by dissolving the appropriate amount of Sodium Perborate Tetrahydrate in warm water. The concentration depends on the type of fabric and the desired level of bleaching. Immerse the textile in the solution for a certain period, usually 30 minutes to a few hours, and then rinse thoroughly with water.
**In Disinfection**: For surface disinfection, dissolve the compound in water to form a disinfectant solution. Use a cloth or sprayer to apply the solution to the surface, and let it sit for a sufficient contact time (usually 10 - 15 minutes) before wiping or rinsing.
**Case 1: Laundry Cleaning**
A family had a set of white tablecloths stained with red wine. They added a laundry detergent containing Sodium Perborate Tetrahydrate to the washing machine and set the temperature to 50°C. After a normal wash cycle, the red wine stains were almost completely removed, and the tablecloths regained their original white color.
**Case 2: Oral Hygiene**
A person with tea - stained teeth started using a toothpaste containing Sodium Perborate Tetrahydrate. After two weeks of regular use, the tea stains on the teeth became significantly lighter, and the overall appearance of the teeth improved.
**Case 3: Textile Bleaching**
A textile factory needed to bleach a batch of cotton fabric. They prepared a bleaching solution with Sodium Perborate Tetrahydrate at a concentration of 5 g/L. The fabric was immersed in the solution for 2 hours at 50°C. After bleaching and rinsing, the cotton fabric achieved a high level of whiteness suitable for further dyeing and finishing processes.
