Description

FIELD OF THE INVENTION

[0001] The present invention relates to the preservation of personal care formulations with synergistic blends of three types of ingredients that offer a broad spectrum of activity against the microbes namely, an undecylenic acid derivative of Formula (I), an octanoic acid component of Formula (II) and a liquid alcohol ether, 2-phenoxy ethanol or 2-ethyl hexyl glyceryl ether or blend of the two. Further, the invention relates to the use of the combinations of three types of cosmetic ingredients.BACKGROUND AND PRIOR ART OF THE INVENTION

[0002] Preservation of personal care products from microbial contamination has become a difficult task since the available approved antimicrobials are very few and those which have good antimicrobial activity are quite toxic. Consumers want products meant for topical applications to be free from toxic antimicrobials that are used as preservatives. This situation is partly addressed by exploiting the synergy between disparate of anti...
