Aminobenzoic acid, also known as p-aminobenzoic acid, is a common cosmetic raw material with antioxidant, whitening, anti-inflammatory and other effects. However, improper use may cause adverse reactions, so the correct use of aminobenzoic acid is very important. The following are some precautions for the use of aminobenzoic acid:

1. Concentration selection: aminobenzoic acid can be used in skin care products and whitening products, and the general recommend concentration is 0.5%~ 2%. When making cosmetics, choose the appropriate concentration according to the formula and efficacy of different products to avoid excessive use.

2. Sunscreen formula: Aminobenzoic acid combined with other chemical ingredients such as vitamin C can enhance its antioxidant effect, but it will also increase its sensitivity to light. Therefore, in the preparation of sunscreen products, attention should be paid to avoid direct contact between aminobenzoic acid and ultraviolet rays, so as to avoid photosensitive reaction.

3. pH control: Aminobenzoic acid is more stable when the pH is low. It is recommended to add it to products with a pH of 3~5. When using, pay attention to the overall pH value of cosmetics to avoid adverse reactions with other ingredients.

4. Preservation Note: Aminophenol is sensitive to light and heat, and is easy to oxidize and discolor, so avoid direct sunlight and high temperature environment when using and storing. It is recommended to keep it in a cool, dry place, sealed to avoid moisture.

5. Allergy test: When using a new product, it is recommended to perform a skin allergy test to ensure that there is no allergic reaction to aminophenol. You can do a small area test in the earlobe or inner wrist to observe whether there are redness, itching and other adverse reactions within 24 hours.

To sum up, the use of aminobenzoic acid should pay attention to concentration selection, sunscreen formula, pH control, preservation attention and allergy testing. Proper use of aminobenzoic acid can give full play to its antioxidant, whitening and other effects, to avoid the occurrence of adverse reactions. I hope the above content can help you better understand and use aminobenzoic acid, and bring better results for skin care.
