  • Publication number: 20230200380
    Abstract: Compositions containing at least one compound of Formula (I) are useful as carriers for at least one active ingredient. In Formula (I), R1 is a monovalent aliphatic radical having 1 to 22 carbon atoms; R2 is in each case independently a hydrogen radical or a methyl radical; n is a number from 1 to 300; and at least one R2 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.

  • Publication number: 20220211036
    Abstract: Compositions containing at least one polyglycerol ester and preferably, at least one emulsifier, can be used as a carrier for an active microbiological ingredient. Compositions containing both the carrier and the active microbiological ingredient are useful; and methods of increasing the storage stability of the active microbiological ingredient can be used with the composition. These compositions can be also used for the treatment of plants, for the treatment of seed, for the treatment of soils, as a biostimulant, as a probiotic food supplement, or as a probiotic animal feed additive.
