A-Hydroxy Acid Test

α-hydroxy acids (AHAs) constitute a category of organic acids distinguished by the presence of a hydroxyl group on a carbon atom adjacent to a carboxylic acid group. These compounds possess the ability to effectively stimulate skin cells, which is why they are favored in cosmetics.

Cosmetics containing AHAs offer a multitude of benefits, including the reduction of fine lines and superficial wrinkles, enhancements in skin texture and tone, the unclogging of pores, and overall improvements in skin condition.

However, it's noted that cosmetic products containing AHAs for topical application can render the skin more sensitive to sunlight during usage and for a period of up to one week after discontinuation. This heightened sensitivity makes individuals more prone to sunburn.

Moreover, AHAs may induce allergic reactions for some people, resulting in symptoms like redness, swelling, itching, or other allergic responses.

Professional Sample Preparation

Sample preparation for cosmetics, including emulsions, serums, and moisturizers to ensure accurate analysis.

• For liquid, it needs to be diluted to the appropriate concentration.
• For solid and powder, grind further to obtain finer particles.
• For cream and oil, extraction, concentration, centrifugation, filtration, washing, dissolving and other operations as appropriate.

Precise Analysis

We use cutting-edge methods to ensure accurate detection of AHAs in cosmetics, including the following technologies.

• High-performance liquid chromatography (HPLC) is usually used to quantitatively detect the components of a substance by comparing it to a standard.
• Gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry (GCMS&LCMS) are used to qualitatively identify certain compounds.

Detailed Reports

We provide detailed reports that not only specify the AHAs content but also offer supplementary explanations about official regulations or restrictions outlined in relevant authorities' documents.
