Suggested is a cosmetic or pharmaceutical or detergent composition comprising 1,2 pentanediol, wherein said 1,2-pentanediol is obtained from a process comprising the following steps: (a) providing at least one starting material selected from furfuryl alcohol and furfural; (b) reacting at least one of said starting materials with hydrogen in the presence of a heterogeneous catalyst to form 1,2-pentanediol, wherein said heterogeneous catalyst comprises: one or more metals selected from the group consisting of platinum, rhodium, ruthenium, nickel, palladium and iridium in metallic form and/or one or more compounds of metals selected from the group consisting of platinum, rhodium, ruthenium, nickel, palladium and iridium; and one or more support materials selected from the group consisting of activated carbon, aluminum oxide, silicon dioxide, and silicon carbide; and (c) removing the 1,2-pentanediol thus obtained from the reaction mixture.

Compositions comprising odorless 1,2-pentanediol

Suggested is a detergent composition, comprising or consisting of: (a) at least one surfactant and (b) at least one 1,2 alkanediol having 5 to 14 carbon atoms.

Detergent composition

Suggested is an antimicrobial mixture comprising or consisting of (a) at least one monocyclic sesquiterpene alcohol, (b) at least one active selected from the group consisting of 4-hydroxyacetophenone, sorbitan caprylate, cocamidopropyl PG-dimonium chloride phosphate, tetrasodium glutamate diacetate, glyceryl caprylate and glyceryl caprate, and optionally (c) at least one additional antimicrobial agent different from components (a) and (b).
