Toothpaste Thickenning Precipitated Silica
What are the characteristics of silicon dioxide used in toothpaste?
1. The baisi dioxide used in toothpaste has stable chemical properties and does not react with other ingredients in zhi toothpaste (such as fluoride, Chinese herbal medicine, spices, etc.), so it has the best compatibility.
2. Silica for toothpaste is a safe and non-toxic food additive and pharmaceutical auxiliary widely used in the world. Because of its stable physicochemical properties, it will not react with human gastric juice and saliva, so it has the best safety.
3. As an excellent stabilizer, silicon dioxide for toothpaste has been widely used in food, drink, medicine and other aspects. For example, as a beer stabilizer, tens of thousands of tons will be consumed worldwide every year. Silica gel for toothpaste has excellent storage stabilizer, especially to improve the stability of fluoride in anti caries toothpastes. It is most appropriate.
This thickenning silicon dioxide is a high structure product with high oil absorption value, large specific surface area, high refractive index and light transmittance, generally greater than 90%. It has good compatibility, extremely fine particle size and superior water force.
