An oil-in-water emulsion which includes one or more amino polyorganosiloxanes (A1), one or more silicone resins (A2), a surfactant composition (B) and water. The oil-in-water emulsion forms a film having a higher degree of crosslinking and an improved strength. Additionally, the oil-in-water emulsion is usable within hair care products to make hairstyles hold and offer a smooth, non-sticky hand feel. Furthermore, the oil-in-water emulsion also has good storage stability.

The disclosure relates to compositions comprising (a) at least one cyclodextrin or derivative thereof; (b) at least one solvent; (c) optionally at least one cationic surfactant; (c) optionally at least one emulsifier; (d) optionally at least one silicone; and (e) optionally at least one oil. The compositions can be used for imparting benefits to keratin fibers, such as elongation of hair curls. The disclosure also relates to methods of using the compositions.

A chromic composition adapted for application to a substrate comprising a reversible colour-change composition and a binder composition is provided. The colour change composition includes a leuco-dye and/or liquid crystal. The composition may be applied to keratinous material, polymers or other substrates to provide a colour change effect and other desirable properties such as natural feel and durability.

A new composition allowing straightening hair including an amino acid, a protein, an alcohol and a vegetable oil, as well as a method for straightening hair implementing the composition.

Agents and methods for coloring keratinous material, in particular human hair, are provided. In one example, the agent includes (a1) at least one amino-functionalized silicone polymer, (a2) at least one color-imparting compound, and (a3) at least one addition product of ethylene oxide to the esters of C.sub.12-C.sub.24 fatty acids and C.sub.1-C.sub.12 aliphatic alcohols.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair, comprising the following steps:

(1) Providing an agent (a), wherein the agent (a) comprises:

(a1) at least one amino-functionalized silicone polymer, and (a2) at least one colorant compound,

(2) providing an agent (b), wherein the agent (b) comprises, based on the total weight of the agent (b): (b1) 0 to about 50 wt. % water and (b2) at least one fat component,

(3) Preparation of an application mixture by mixing agents (a) and (b),

(4) Apply the application mixture prepared in step (3) to the keratinous material,

(5) Exposure of the application mixture applied in step (4) to the keratinous material; and

(6) Rinse the application mixture with water.

The present disclosure relates to silica particles comprising repeating units of (SiO.sub.4/2) that are spherical in shape, which has the benefit of compatibility with personal care components and the resulting personal care applications. The present disclosure also relates to methods of preparing silica particles.
