The Characteristics of Potassium Citrate:
Potassium Citrate is a white powder that is odorless, with a slight saline taste. This product is highly hygroscopic and must be protected from humidity and high temperatures during storage.
The Applications of Potassium Citrate:
1.Potassium citrate is used as a buffer, chelating agent, stabilizer, antioxidant, emulsifier, flavoring agent, etc. in the food industry, like in canning, fruit juice, wine and confectionery.
2.As an ingredient in vitamin supplements, Potassium Citrate can improve health and help conditions.
3.As an ingredient in personal care products, Potassium Citrate naturally preserves cosmetics and personal care products by chelating metals. Citric acid and its salts are also added to cosmetics to help adjust the acid/base balance.
4.Potassium citrate has a washing effect because it prevents contaminants from sticking to the fabric. It is commonly used in the textile industry.Also used for decoloring.
