A process for dyeing keratinous material is disclosed. The process includes applying an agent (a) and an agent (b) to the keratinous material. The agent (a) comprises (a1) at least one organic silicon compound, and (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound. A multi-component packaging unit is also disclosed, and comprises, separately packaged, a first container comprising an agent (a′), a second container comprising an agent (a″), and a third container comprising an agent (b). The agent (a′) comprises (a1) at least one organic silicon compound. The agent (a″) comprises (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.

The inventions relate to cosmetology and are intended to increase a cosmetic effect. A mask comprises a cream-type cosmetic agent and an additional reagent, which are isolated from one another. The agent contains a water-soluble biocompatible polymer which has a mass in the range of 50,000-1,000,000 Da and is capable of entering into a cross-polymerisation reaction. The reagent consists of a substance-electrolyte solution containing multicharged ions. The mass ratio of polymer and substance-electrolyte is from 10:1 to 1:1 respectively. A method involves separately applying to the skin the cream-type agent and then the additional reagent on top.

A new composition for hair dyeing includes an amino acid, a protein, an alcohol, a mineral powder, a vegetable oil and a dye or a pigment, as well as a method for dyeing hair implementing said composition.

A capsule delivery system. The system has a first capsule containing a first capsule wall encapsulating a first active material and a second capsule containing a second capsule wall encapsulating a second active material. The first and second capsules differ in their wall materials, amounts of wall materials, ratios of wall materials, core modifiers, scavengers, active materials, curing temperatures, heating rates, curing times, or a combination thereof. Also provided is a consumer product containing this capsule delivery system.

Hypotonic microbicidal compositions including an antimicrobial, such as an antiviral compound, and a pharmaceutically acceptable carrier in a solution formulation having hypotonic osmolarity have been developed for administration rectally to the gastrointestinal mucosa. In a preferred embodiment for use in preventing or decreasing HIV infection, the microbicidal is tenofovir, or a prodrug or derivative thereof. The formulations may include additional agents such as surfactants to enhance cleansing, buffers, or preservatives. Polymers may be included for osmolarity as well as comfort.
