EDTA-3K is a chemical substance also known as tripotassium ethylenediaminetetraacetic acid or 3K (EDTA). It is a white crystalline powder, odorless, easily soluble in water, and has stable performance. It has good chelating ability and can combine with cations such as calcium ions in the blood to form stable chelates, effectively controlling the concentration of calcium ions in the blood and preventing coagulation for a certain period of time. And EDTA-3K is also used in cosmetics as a moisturizer, stabilizer, etc. It helps to keep the skin hydrated and protect skin cells from free radical damage. At the same time, it is often used to prepare some special cosmetic additives, such as whitening agents.
（1） The reason why potassium ethylenediaminetetraacetate is used in cosmetics:
1. High safety: Tripotassium ethylenediaminetetraacetate is a safe and suitable chelating agent for cosmetics. It is considered non-toxic in many places and is therefore often added to various cosmetics.
2. Efficient chelation ability: Tripotassium ethylenediaminetetraacetate can effectively chelate metal ions, preventing their oxidation on cosmetics, thereby ensuring product quality and stability.
3. Good compatibility: Tripotassium ethylenediaminetetraacetate has good compatibility with other cosmetic ingredients, making it easier to use in combination with other ingredients during the formulation process, reducing production difficulty and cost.
4. Multiple functions: Tripotassium ethylenediaminetetraacetate has various functions, such as moisturizing and anticoagulating, so it can play an important role in the cosmetics field.
5. Good stability: The chemical properties of potassium ethylenediaminetetraacetate are stable, which enables it to play an important role in various application fields. Whether it is food processing, pharmaceutical preparation, or cosmetic production, it can maintain its effectiveness under harsh conditions.
Please note that although potassium ethylenediaminetetraacetate has many applications in cosmetics, its specific use must comply with relevant regulations, and the amount added must comply with relevant requirements and standards.
（2） Tripotassium ethylenediaminetetraacetate can be used as a variety of ingredients in cosmetics, such as moisturizers, antioxidants, anticoagulants, chelating agents, etc. The following are some types of cosmetics that may have added potassium ethylenediaminetetraacetate:
1. Skin care products: EDTA can be added to skin care products as humectant and antioxidant, such as face cream, lotion, essence, etc. It can enhance the moisturizing effect of the product while preventing the oxidation of metal ions in the product.
2. Cosmetics: EDTA can be used as stabilizer and humectant in cosmetics, such as lipstick, eye shadow, liquid foundation, etc. It can improve the stability of the product, extend its service life, and maintain the skin's hydration.
3. Shampoo and shower gel: Tripotassium ethylenediaminetetraacetate can serve as a chelating agent in shampoo and shower gel, removing metal ions from the skin and providing a cleansing effect. At the same time, it can also enhance the moisturizing effect of the product.
4. Anti aging products: EDTA can be used as antioxidant and humectant in anti-aging products, such as eye cream, facial essence, etc. It can effectively prevent the damage of free radicals to the skin while maintaining a hydrated feeling.
It should be noted that the amount of potassium ethylenediaminetetraacetate added to different cosmetics needs to comply with relevant requirements and standards to ensure the safety and effectiveness of the product. Meanwhile, for certain special groups of people, such as those with allergies or sensitive skin, skin testing should be conducted before using cosmetics with added potassium ethylenediaminetetraacetate.
