## Background
This application claims benefit of U.S. Provisional Application No. 60/377,593, filed May 6, 2002.


Disclosed herein is the use of at least one agent chosen from cyclodextrins and the derivatives thereof as a pearlescent agent, in a composition, for example, a cosmetic composition, comprising, in a physiologically acceptable aqueous medium, at least one surfactant. Also disclosed herein are pearlescent compositions comprising, in a physiologically acceptable aqueous medium, at least one agent chosen from cyclodextrins and the derivatives thereof and at least one surfactant; further disclosed herein are pearlescent compositions comprising, in a physiologically acceptable aqueous medium, at least one agent chosen from cyclodextrins and the derivatives thereof, at least one surfactant, and at least one conditioning agent. Also disclosed herein is the use of at least one agent chosen from cyclodextrins and the derivatives thereof for suspending an insoluble conditioning agent.
As used herein, the term “pearling agent” or “pearlescent agent” means an agent producing at least one of pearlescent, iridescent, shimmering and metallic appearances and effects.
It is well-known that hair which has been sensitized (i.e. damaged and/or embrittled) to various degrees under the action of atmospheric agents or under the action of mechanical or chemical treatments, such as dyeing, bleaching and/or permanent waving, may often be difficult to disentangle and to style, and may lack softness.
The use of conditioning agents, for example, insoluble conditioning agents that can facilitate the disentanglement of hair and can make hair soft, shiny and supple has already been recommended in compositions for washing or care of a keratinous material such as hair.
Given the insoluble character of certain conditioning agents such as silicones and oils, it is sought to be able to maintain the conditioning agents in a uniform dispersion in the medium without, however, causing a drop in the viscosity, and the detergent and foaming properties of the compositions. The conditioning agents, such as silicones and oils, can also be carried to the treated keratinous materials and may confer on them, following the application, at least one property of softness, sheen and disentanglement.
It is also well-known that products, for example, cosmetic products, having an iridescent, shimmering or metallic appearance or effect are widely appreciated by consumers for their esthetic appearance which can give an appearance of richness to the product. The agents which can provide this effect are pearling agents which may be in the form of crystals which can remain dispersed in the compositions and which can reflect light.
Long-chain ester derivatives are widely used for pearling compositions, for example, pearling cosmetic compositions. However, these derivatives can exhibit problems of crystallization which may cause a variation in the viscosity of the compositions over time.
Long-chain ether or thioether derivatives such as those described in Patent Application Nos. EP457688 and WO98/03155 are also known. However, they can opacify the compositions and may not give or not sufficiently give the compositions pearliness.
To obtain the pearlescent effect, the compositions comprising the pearlescent agents can be heated to above the melting point of the pearlescent agents and then cooled in order to cause them to crystallize.
It has been observed that these pearlescent agents, because of their low density, may have the disadvantage of rising to the surface of a shampoo and may form, as a result, a layer on the surface which can be inesthetic to the consumer.
Furthermore, these fatty chain compounds may have, in some cases, the disadvantages of giving a charged feel to the hair, and a lack of lightness and volume of the hair.
A need therefore still exists for novel pearlescent agents which may not exhibit at least one of the disadvantages mentioned above and which may also allow the use of constituents such as insoluble conditioning agents, for example, silicones.
The inventor has discovered, surprisingly, that it was possible to formulate compositions, such as cosmetic compositions, for the treatment of a keratinous material, for example, shampoos having a pearlescent appearance while having at least one of the desired esthetic and cosmetic properties, comprising, in these compositions, at least one agent chosen from cyclodextrins and the derivatives thereof and, for example, at least one surfactant.
The inventor has discovered that the use of at least one agent chosen from cyclodextrins and the derivatives thereof may make it possible to pearl and/or enhance pearling of compositions, for example, cosmetic compositions, comprising at least one surfactant.
The pearlescence obtained may be very shiny. Moreover, the preparation of the compositions may be carried out in the cold state, which can be very advantageous.
Furthermore, the at least one agent chosen from cyclodextrins and the derivatives thereof may make it possible to maintain in suspension conditioning agents which are insoluble in water and/or the composition. The at least one agent chosen from cyclodextrins and the derivatives thereof may also make it possible to stabilize the viscosity of the composition according to the temperature, i.e., it may reduce the variation in the viscosity with the temperature.
Disclosed herein is the use of at least one agent chosen from cyclodextrins and the derivatives thereof as a novel pearlescent and/or opacifying agent. Further disclosed herein is the use of at least one agent chosen from cyclodextrins and the derivatives thereof as a novel pearlescent and/or opacifying agent in a cosmetic composition, for example, a washing and/or conditioning composition, comprising a physiologically acceptable aqueous medium and at least one surfactant.
Also disclosed herein are pearlescent compositions, for example, pearlescent cosmetic compositions, comprising, in an aqueous medium, for example, a physiologically acceptable aqueous medium, at least one surfactant and at least one agent chosen from cyclodextrins and the derivatives thereof, wherein the at least one agent chosen from cyclodextrins and the derivatives thereof and the at least one surfactant are present at effective concentrations to pearl the compositions.
Further disclosed herein are pearlescent compositions, for example, pearlescent cosmetic compositions, comprising, in an aqueous medium, for example, a physiologically acceptable aqueous medium, at least one surfactant and at least one agent chosen from cyclodextrins and the derivatives thereof, wherein the at least one agent chosen from cyclodextrins and the derivatives thereof and the at least one surfactant are present at effective concentrations to form an insoluble complex in the compositions.
The compositions disclosed herein may at least satisfactorily exhibit at least one of following properties: homogeneity, stability of the pearlescence, and a viscosity for application to a keratinous material.

When they are chosen from volatile polyorganosiloxanes, the silicones may, for example, be chosen from those volatile polyorganosiloxanes having a boiling point ranging from 60° C. to 260° C., and further, for example, may be chosen from:
(i) at least one of cyclic silicones comprising, for example, from 3 to 7 silicon atoms, for example, from 4 to 5 silicon atoms. They may, for example, be chosen from octamethylcyclotetrasiloxane marketed, for example, under the name “VOLATILE SILICONE 7207” by UNION CARBIDE and “SILBIONE 70045 V 2” by RHODIA CHIMIE, and decamethylcyclopentasiloxane marketed under the name “VOLATILE SILICONE 7158” by UNION CARBIDE, “SILBIONE 70045 V 5” by RHODIA CHIMIE and mixtures thereof.
The cyclic silicones may also be chosen from cyclocopolymers of the dimethylsiloxane/methylalkylsiloxane type, such as the “SILICONE VOLATILE FZ 3109” marketed by the company UNION CARBIDE, having the chemical structure:

(ii) linear volatile silicones comprising from 2 to 9 silicon atoms and having a viscosity of less than or equal to 5×10−6 m2/s at 25° C. For example, decamethyltetrasiloxane marketed, for example, under the name “SH 200” by the company TORAY SILICONE can be used. Silicones chosen from this class are also described in the article published in Cosmetics and Toiletries, Vol. 91, January 76, p. 27-32—TODD & BYERS “Volatile Silicone fluids for cosmetics”.
The nonvolatile silicones may, for example, be chosen from at least one of polyalkylsiloxanes, polyarylsiloxanes, polyalkylarylsiloxanes, silicone gums and resins, and polyorganosiloxanes modified by organofunctional groups.
