The present invention relates to dust-free preparations dispersible in cold water. These preparations consist of particles comprising water-insoluble or only sparingly water-soluble active substance(s), said particles being coated with one or more layers, the outermost layer comprising as principal component one or more hydrophobic powdering agents on which at least one dispersant is absorbed. The invention also relates to a process for producing these particles and to the use thereof in food supplements, foodstuffs, animal feeds, personal-care products, and medicaments.

Dust-free cold-water-dispersible preparations

Thermoplastic elastomer compositions can be use for medical applications, Comprising: a) 97.1 to 90.9 wt.-% star-shaped block copolymer A with identical arms of the structure [S-(S/B)-(S/B)-(S/B)-S2]-X, where Sand Sare vinylaromatic hard polymer and S/B are soft random vinylaromatic/diene copolymer blocks; X is a coupling center; and b) 2.9 to 9.1 wt.-% plasticizer B.

Non-sticky, soft and transparent styrenic thermoplastic elastomers

Polymer compositions comprising stiff and tough star shaped styrene butadiene block-copolymers A1 and A2 can be used for making shrink films. Block copolymer A2 preferably has the structure with hard blocks Sand S, hard random copolymer blocks (B/S), soft random copolymer blocks (B/S)coupled by a coupling agent X.
