Ribes nigrum, or black currant, is a small fruiting shrub native to Europe and northern Asia. The edible fruit is a dark purple color and typically grows 1 cm in diameter. Often used in jam, candy and juices, the popularity of black currants has recently increased due to its high concentration of antioxidants and vitamins, such as vitamin C.
nterestingly, black currants are also an excellent source of phytochemicals that exhibit antimicrobial properties. These phytochemicals can be isolated from the fruit for use as antimicrobial agents in cosmetic and personal care products. The desire for alternatives to traditional preservatives is not novel, however the notion of an antimicrobial with a secondary active that provides value-added benefits is relatively new. Active Micro Technologies developed PhytoCide Black Currant Powder, an extract rich in phytochemicals that not only inhibits microbial growth, but also have anti-inflammatory benefits.
Black currants are rich in both ellagitannins and anthocyanins which are polyphenols with anti-inflammatory properties. Useful in an array of aqueous systems and emulsions specifically designed for sensitive skin, PhytoCide Black Currant Powder is an effective antimicrobial that can also act to preserve systems.
This incorporation will either reduce the level of traditional preservatives being used or help create a blend of natural antimicrobials. Additionally the anti-inflammatory properties of the black currant may help quell mild irritation associated with both sensitive and problem skin.
Minimum Inhibitory Concentrations (MIC), using a standard growth media dilution method in addition to both bacterial and fungal cultures, were determined in order to evaluate the ability of PhytoCide Black Currant Powder to protect against microbial proliferation.
