Use of polyethers as carrier for active ingredients
Compositions containing at least one compound of Formula (I) are useful as carriers for at least one active ingredient. R 1 O—[(C 2 H 3 R 2 )—O] n —H Formula (I). In Formula (I), R 1 is a monovalent aliphatic radical having 1 to 22 carbon atoms; R 2 is in each case independently a hydrogen radical or a methyl radical; n is a number from 1 to 300; and at least one R 2 radical is a methyl radical. Methods can be used for storing the active ingredient in the carrier and active ingredient compositions contain both the carrier and the active ingredient. The active ingredient compositions can be used for the treatment of plants, seed, and soils; and can be used as a biostimulant, a probiotic food supplement, a probiotic animal feed additive, a plant protection product, or a probiotic medicament. The active ingredient compositions can be used in corresponding methods of treating plants, seed, or soils.
