  S-(+)-Methoprene (I) was synthesized from (+)-beta-citronellene (III) with an optical purity of about 50%. The optical purity of the key intermediate, S-(-)-7-methoxy-3,7-dimethyl-1-octanol (IV), can be increased by fractional crystallization of the optically active acid phthalate salt (VI) followed by hydrolytic regeneration of alcohol (IV). The yield of (I) at the final synthetic stage can be increased by use of interphase catalysis. S-(+)-Methoprene has a higher morphogenetic activity than the racemic form.

  A solid, particulate composition having at least one water-soluble carrier material and at least one fragrance, wherein the carrier material is a water-containing salt (hydrate) whose water vapour partial pressure at a specific temperature in the range from 30 to 100° C. corresponds to the H 2 O partial pressure of the saturated solution of this salt, such that the salt melts at this temperature in its own crystal water. The composition is characterized in that it has a distinctly improved water solubility compared to known polyethylene glycol-based compositions. The invention further relates to methods for producing the solid composition, and to a washing or cleaning product including the solid composition. In addition, the invention relates to the use of a washing or cleaning product for cleaning textiles or hard surfaces, and corresponding methods for cleaning textiles or hard surfaces using a washing or cleaning product of this kind.
