Abstract: The invention relates to a topical antimicrobial formulation comprising an acidic substance comprising at least one organic acid diluted in an aqueous solvent while having an action deleterious against microbes, said acidic substance having an acidity constant pKa that is less than 6, as well as: between 1% and 10% by weight of acidic substance in the INCI base; a basic substance the quantity of which in the formulation is such that the pH is comprised between the pKa of the acidic substance and 8; between 0.1% and 15% by weight of a booster substance capable of biochemically interacting with the membrane of the microbes to facilitate the deleterious action of the acidic substance, said booster substance comprising at least one compound in the INCI base selected from amphiphilic compounds, chelating compounds having an ability to associate with divalent ions or sterols, or polyphenolic compounds.

Abstract: An aqueous formulation comprising between 0.1% and 50% by weight of lipophilic composition, said formulation further comprising between 0.1% and 10% by weight of homogenising component comprising at least microcrystalline cellulose; between 0.01% and 2% by weight of clay; and the remainder in water.

Abstract: The invention relates to an insect repellent composition comprising a compound having one or more fatty acid with between 9 and 21 carbon atoms, a non-aqueous solvent and less than 1% by weight of water.
