Bamboo vinegar, containing numerous organic compounds, shows promise in cosmetics for its anti-acne properties through a refined, controlled-release system that minimizes skin irritation and enhances bacteriostatic effects, with potential for broader cosmetic uses.
Bamboo vinegar is a concentrated liquid derived from bamboo through a high-temperature, anaerobic process. It comprises over 200 organic compounds, including organic acids, phenols, ketones, alcohols, and esters, with acetic Nevertheless, bamboo vinegar has anti-acne potential, especially against the inhibitory effect of Propionibacterium acnes, the key microorganism in the pathogenesis of acne. While antibiotics are commonly used to treat acne, the concerns for drug resistance have limited their use. In a study published in the Journal of Dermatologic Science and Cosmetic Technology, a team of researchers from Central South University of Forestry and Technology in China explored the mechanism of the controlled-release system of bamboo vinegar and its application potential in cosmetics. “Bamboo vinegar was refined through reduced-pressure distillation, which increased the content of organic acids, reduced tar content, and enhanced the active ingredients while minimizing harmful components,” explains corresponding author Sheng Zhang. “We used activated bamboo charcoal to adsorb the bamboo vinegar, allowing for a gradual release over a period exceeding two hours, effectively demonstrating a slow-release effect.” The findings suggest that refined bamboo vinegar could be a promising raw material for anti-acne cosmetic formulations. The release rate of the bamboo charcoal/bamboo vinegar complex in water reached 70.57% within 15 minutes and then slowed to a plateau. This slow-release behavior aligns with the Ritger-Peppas model, which is advantageous for reducing skin irritation and extending the bacteriostatic duration. “The findings present a novel concept for anti-acne cosmetics and lay the groundwork for further research into the use of bamboo vinegar slow-release systems with bamboo charcoal as a carrier,” adds Zhang. “Future studies should explore additional cosmetic benefits of bamboo vinegar, such as dandruff removal, anti-wrinkle effects, and more.” Reference: “Inhibition of Propionibacterium acnes by refined bamboo vinegar and preparation of the slow-release system with bamboo charcoal as the carrier” by Ziyi Li, Yanan Wang and Sheng Zhang, 29 February 2024, Journal of Dermatologic Science and Cosmetic Technology.
