1. Whitening effect comparison with other related cosmetic products:
Test materials:The emulsion contains 1% alpha-arbutin, kojic acid, beta-arbutin and hydroquinone
Test population and time :Two groups of 80 years old Chinese women had their forearms tested for one month .
Test method:The skin luminance parameter L was determined by spectrophotometer for comparison.The result show up by bar graph, whitening effect of kojic acid is better than other two.
2.What is the solubility of kojic acid?
Kojic acid is easily soluble in water, alcohol, acetone, hardly soluble in most other solvents.And slightly soluble in ethyl acetate,ether, chloroform, and pyridine.
Although kojic acid is soluble in water, its solubility is small, and it's great influenced by temperature, which is conducive to concentration and cooling crystallization.
The kojic acid powder solution with a concentration of 0.5% is treated at 100 ° C
for 3 hours or sunlight for 5 hours at different pH. As a result, the solution becomes pale yellow to yellow-brown in the pH range
of 5 to 7, and There was little change in pH4.
3. Flow chart of kojic acid.
Grasp every step of the production process from the source.
4. Stability data for kojic acid powder Powder :
kojic acid powder easily turns yellow when exposed to light and heat, which affects the shelf life of kojic acid powder
cosmetics. Cryopreservation and the addition of ascorbic acid and sunscreen agents such as hydroxybenzophenone
(2-hydroxy-4-methoxybenzophenone) can enhance its stability.
kojic acid powder is unstable to light and heat.
kojic acid powder interacts with ferric chloride in a special red color. This method can be used to quantify kojic acid powder.
kojic acid powder can reduce Ferrin reagent and silver ammonia nitrate.
