The present disclosure is directed to dissolvable objects that are configurable. The dissolvable objects are dissolvable in a solvent, such as water in a bath tub. The dissolvable objects are further configured to receive a seletable additive, which can be an insertion of another object and/or liquid. The present disclosure is also directed to methods of manufacturing dissolvable objects that are configurable.

The subject of the present disclosure is a method for dyeing keratinous material, in particular human hair. The method includes applying an agent (a) to the keratinous material. The agent (a) includes one or more organic silicon compound selected from the group of silanes having one, two or three silicon atoms, (a2) a first colorant compound including one or more lenticular substrate platelet-based pigment, and (a3) a second coloring compound. The method further includes applying an agent (b) to the keratinous material. The agent (b) includes at least one sealing reagent. Also disclosed are multi-component packaging unit (kit-of-parts) for dyeing keratinous material.

Microcapsules can be formed of a phosphate ester and a multivalent ion. The microcapsules can encapsulate a core material having a C log P value of about 0 or greater. The phosphate ester can be lipophilic and insoluble in aqueous solutions.

Microcapsule slurries can be formed from a phosphate ester and a multivalent ion. The microcapsules can encapsulate a core material misicible with the phosphate ester. The phosphate ester can be lipophilic and insoluble in aqueous solutions.
