Abstract
The disclosure relates to the field of reducing malodor, which is due to bacterial conversion of molecules that are present in sweat. Indeed, the disclosure describes acids, which steer the microbiome by inhibiting the growth of specific malodor-producing bacteria and/or promoting the growth of bacteria known to be beneficial in relation to malodor. The acids of the disclosure can thus be used in deodorants, washing powders, clothing finishing agents or any method to reduce malodor. The disclosure thus relates to a topical composition or textile finisher for use as a prebiotic.
Claims17
A method of selectively promoting on skin or a textile growth, metabolism, and/or colonization of good-odor associated bacteria selected from the group consisting of Staphylococcus epidermidis, Acinetobacter spp, Propionibacterium acnes and Enhydrobacter aerosaccus bacteria, and/or selectively inhibiting on skin or a textile the growth, metabolism, and/or colonization of malodor-associated bacteria comprising Corynebacterium tuberculostearicum, Corynebacterium amycolatum, Staphylococcus hominis, Micrococcus luteus, or Enterobacter cloacae, the method comprising:
- administering or applying to the skin or textile a composition comprising an acid selected from the group consisting of, fumaric acid, mucic acid, γ-aminobutyric acid, α-keto-glutaric acid, quinic acid, D-saccharic acid, glyoxylic acid, D-glucosaminic acid, D,L-α-amino-caprylic acid, N-acetyl-neuraminic acid, D,L-α-amino-N-butyric acid, orotic acid, ε-amino-N-caproic acid, β-hydroxybutyric acid, tropic acid, hippuric acid, and any combination thereof.
