AI Technical Summary
Technical Problem
Existing anti-dandruff products do not provide effective long-lasting antimicrobial protection after use, especially against Malassezia, and may have adverse effects on resident bacteria on the skin and scalp.
Method used
A combination of glycine and N-acylglycine containing 11 carbon atoms, in a weight ratio of 1:10 to 30:1, is used as a major component in cosmetic compositions to synergistically provide antimicrobial protection, particularly against Malassezia, while being harmless to Staphylococcus epidermidis and Propionibacterium acnes.
Benefits of technology
It provides synergistic antimicrobial protection on the skin and scalp, reduces dandruff, and is harmless to resident bacteria, thus enhancing the product's long-lasting anti-dandruff effect.
