Disodium monofluorophosphate, with the CAS number 10163-15-2, is a white crystalline powder. It has a molecular formula of Na₂PO₃F and a molecular weight of approximately 143.95 g/mol. This product is typically available in a high - purity form, often with a purity level of 98% or above. It is soluble in water, and its solubility at room temperature allows for easy integration into various formulations. The product is stable under normal storage conditions but should be kept away from strong acids and oxidizing agents.
One of the primary uses of disodium monofluorophosphate is in the oral care industry. It is a common ingredient in toothpaste as a fluoridating agent. Fluoride helps to prevent tooth decay by strengthening tooth enamel and making it more resistant to acid attacks from bacteria in the mouth. Additionally, it can inhibit the growth of plaque - forming bacteria, reducing the risk of gum disease.
In the food industry, disodium monofluorophosphate can be used as a preservative and a stabilizer. It can help to extend the shelf - life of certain food products by preventing the growth of microorganisms and maintaining the product's texture and quality.
It also has applications in the pharmaceutical industry. In some medications, it can be used as an additive to enhance the stability and effectiveness of the active ingredients.
When using disodium monofluorophosphate in toothpaste production, it should be added in an appropriate concentration. The typical concentration in toothpaste ranges from 0.76% to 1% by weight. First, dissolve the disodium monofluorophosphate in a small amount of water to form a homogeneous solution. Then, gradually add this solution to the main toothpaste base under gentle stirring to ensure even distribution.
In the food industry, the usage amount needs to comply with relevant food safety regulations. Usually, it is added during the mixing stage of food production. Dissolve it in a suitable solvent before adding it to the food mixture to ensure uniform dispersion.
In pharmaceutical applications, strict quality control and dosage calculation are required. It should be added according to the specific formulation and manufacturing process of the medication, under the guidance of professional pharmaceutical personnel.
Case 1: Oral Care Company
A well - known oral care company introduced a new toothpaste formula with disodium monofluorophosphate. They conducted a clinical trial on a group of 500 volunteers over a period of 6 months. The results showed that the group using the new toothpaste had a 30% reduction in new cavities compared to the control group using a non - fluoridated toothpaste. The participants also reported better oral hygiene and reduced gum inflammation.
Case 2: Food Manufacturer
A food manufacturer used disodium monofluorophosphate as a preservative in a fruit - based beverage. They compared the shelf - life of the beverage with and without the additive. The beverage with disodium monofluorophosphate remained stable and maintained its flavor and color for up to 3 months longer than the non - treated beverage, reducing product spoilage and waste.
