Buy Kojic acid powder, Best Kojic acid powder for Skin Care
1. Is best kojic acid powder safe in cosmetics?
(1) Best Kojic acid powder is not an acute, chronic, reproductive toxic substance. Although some animal
data suggest tumor promotion and weak carcinogenesis, kojic acid is very slowly absorbed from the human
skin into the circulation, and it is likely that the thresholds for these effects are not reached. Kojic acid powder
is safe in cosmetics at concentrations below 2%.
(2) In a patch test conducted on 220 female patients, there was no evidence that less than 2% of "kojic acid"
products caused contact dermatitis. In terms of phototoxicity, it was confirmed that "Kojic acid" had no phototoxicity
and did not cause a delayed contact reaction. Therefore, products containing kojic acid can be used during the day.
2. What is the solubility of Best kojic acid powder ?
Best Kojic acid is easily soluble in water, alcohol, acetone, slightly soluble in ether, ethyl acetate, chloroform,
and pyridine, and hardly soluble in most other solvents.
Although kojic acid is soluble in water, its solubility is not large. Temperature has a great influence on its solubility,
which is conducive to concentration and cooling crystallization.
3. How should Best kojic acid powder be used? How does it work with other products?
Best Kojic acid and placenta extract are used together on the market, which has a better whitening and freckle effect.
Many freckles creams on the market are formulated with these two ingredients.
Best Kojic acid can also be used with VC, but the concentration of VC should not be too large.
Best Kojic acid and silk fibroin (a good elastin) can also be well matched
4. The stability of Best kojic acid powder
Best Kojic acid powder has relatively high requirements for pH. In an environment with a pH of 4, it can withstand
high temperature challenges. If the pH of the product exceeds 5, it is easy to oxidize and deteriorate.
If you use products containing kojic acid during the day, take sun protection to protect kojic acid from acting on your skin.
If it is not used for a long time, put it in the refrigerator to help keep the kojic acid active and extend the shelf life
