What is phytic acid used for in skincare?

2022 02/27

1 Oral hygiene products: Use the complexing ability of phytic acid (salt) to prevent tartar and pigment from depositing on teeth. It is very common to add phytic acid (salt) to oral products such as toothpaste in foreign countries.

2 Prevent rancidity and deterioration of unsaturated oils: Cosmetic oils often use oils containing essential fatty acids (such as evening primrose oil). The fatty acids of these oils often contain two or more double bonds, which can easily cause oxidative rancidity. It is very common to add a little (0.02-0.4%) phytic acid as an antioxidant in vegetable oils in the food industry.
3 As an antioxidant stabilizer for reducing substances: Reducing raw materials are often used in cosmetics, such as VC, kojic acid, and polyphenols. The pharmaceutical industry has adopted phytic acid as an antioxidant stabilizer in the production process of some pharmaceutical products (such as vitamins). Of course, the process conditions are different, and the oxidation process is also complicated. Specific applications in the cosmetics industry need to explore the best conditions according to the specific conditions.

4 Other applications: 1. Prevent the formation of dandruff. There have been many reports that phytic acid can prevent the formation of dandruff. Phytic acid does not have anti-fungal properties, which may be due to its gentle peeling effect on the scalp; 2. As a stable hydrogen peroxide and peroxide An important reason for the instability of peroxides is the catalytic decomposition of divalent and trivalent metal ions. Phytic acid as a strong complexing agent can stabilize peroxides such as hydrogen peroxide; 3 complexes heavy metal ions such as mercury and lead on the skin surface .
