Salicylic acid, a type of beta hydroxy acid, softens the keratin, promotes epidermal cell proliferation, provides skin moisture, and smoothens the skin. It has effects similar to alpha hydroxy acids. Salicylic acid also possesses functions such as wrinkle reduction, anti-inflammatory properties, antibacterial and acne-fighting abilities, as well as skin cleansing effects. Therefore, it has been used as an effective ingredient in cosmetics for many years. Salicylic acid can dissolve the intercellular substance between keratinocytes, causing the shedding of aged keratin, removing excessively thickened layers of keratin, and promoting skin metabolism. However, due to its poor water solubility and potential for causing allergies, the application of salicylic acid in cosmetics has been limited.

Shandong Binzhou Zhiyuan Biotechnology utilizes supramolecular technology to encapsulate 40% water-soluble salicylic acid using microcapsule technology, greatly enhancing its water solubility, making it stable for use in cosmetic formulations.

With a salicylic acid content as high as 40%, this product features dual-release salicylic acid, minimizing irritation and providing long-lasting effects. Its low usage amount and high water solubility typically range from 7% to 8%.

40% water-soluble salicylic acid can regulate the release rate of salicylic acid on the skin surface, control the local concentration of salicylic acid on the skin surface, ensure the effective concentration of salicylic acid on the skin surface, reduce its irritancy and adverse effects, and make its action more gentle while exerting its effectiveness.
