Description

COMPOSITIONS FOR HAIR CARE COMPRISING POLYISIOXANE RESINS WITH DELOCALIZED ELECTRONS FIELD OF THE INVENTION The present invention relates to hair care compositions. In particular it relates to hair care compositions which provide good conditioning / shine to the hair with reduced tackiness and greasy feel.

BACKGROUND OF THE INVENTION Usually the hair is subjected to a variety of attacks that can cause damage. This includes washing, rinsing, drying, curling, combing stylized, applying permanent, bleaching, exposing elements, etc. In this way, the hair is usually in a dry, rough, non-glossy condition, due to the abrasion of the hair surface and the removal of natural hair oils and other natural conditioning and wetting. A variety of aspects have been developed to mitigate these conditions. These include the use of ultra-mild shampoo compositions, the use of hair conditioning shampoos that attempt to both cleanse and condition hair from a single product and the use of hair conditioning formulations such as products that are rinsed and left on. The hair. Hair care formulations, which remain on hair, provide additional advantages over the other aspects. For example, the formulations for the hair that are left on it are of higher cost effective and work for a longer period since the conditioning ingredients remain in the hair. They are more convenient since the consumer can use the product at any time and do not have to wait to rinse the product. The product can also be applied to the parts of the hair that need the most conditioning benefits. Commonly, the conditioning benefit is provided through the use of hair conditioning agents, such as cationic active surfactants, cationic polymers, silicone conditioning agents, hydrocarbons, other organic and solid aliphatic oils, such as fatty alcohols. These conditioning agents are well known in the art See, for example, WO-A-97/35542 WO-A97 / 35545, WO-A-9735546, all of which describe the use of conditioning agents in shampoo compositions. Ideally, these conditioning agents are deposited on the hair fibers and make the hair have a soft feel and glossy appearance. Preferably, the compositions should be easy to work through the hair to ensure that the agents are completely and uniformly throughout. the arrow d hair. However, conditioning compositions, especially the compositions that are left on the hair, where the rinse step does not exist are usually difficult to spread and may deposit too much conditioning agent in an uneven form. This causes the hair to develop a dirty, coating sensation and leaves the hair limp and disembodied. This is particularly noticeable when the compositions are used repeatedly when the hair is not washed daily. Therefore, it is desirable to formulate compositions comprising as little conditioning agent as possible to obtain the desired benefits while ensuring that the agent is deposited as evenly as possible along the hair shaft.

It has recently been suggested that polysiloxane resins can be used as hair conditioning agents. For example, GB-A-2,297,757, incorporated herein by reference, discloses orgafunctionalized low viscosity siloxilicates and provides examples of their use in hair care compositions. However, this reference does not address the problem of providing hair care compositions to provide shine and conditioning benefits and to work easily through the hair, and that they do not cause to the hair an excessively sticky or greasy sensation. Surprisingly, it has now been found that hair care compositions that are left on it comprise from about 0.001% to about 5% polysiloxane resin, wherein at least one substituent group on the resin possesses delocalized electrons, they have reduced stickiness while providing good conditioning / gloss benefits.

BRIEF DESCRIPTION OF THE INVENTION According to the present invention, there is provided a hair care composition comprising from about 0.001% to 5% polysiloxane resin, wherein at least one substituent group of the resin possesses delocalized electrons, and wherein the composition It is a composition that is left on the hair. The compositions of the present invention have reduced tackiness and greasy appearance while providing good conditioning / gloss benefits. All concentrations and ratios herein are by weight of the hair care composition, unless otherwise indicated.

All averages herein are averages by weight unless otherwise indicated.

DETAILED DESCRIPTION OF THE INVENTION The hair care compositions that are left on the hair of the present invention comprise a polysiloxane resin, wherein at least one substituent group of the resin possesses delocalized electrons. This will be described in more detail later. As used herein, the terms "sticky" and "stickiness" represent the sticky, viscous feel of the hair after the application of some hair care compositions.As used herein, the term "leave over" means A composition for hair care that is intended to be used without a step of rinsing, Therefore the compositions that are left on the hair will generally be left on it until the next hair washing of the user as part of his / her regimen. The compositions that are left on the hair of the present invention will preferably comprise at least about 5% d anionic surfactant and will generally comprise less than 5% nonionic surfactant.

POLYSYLXOXANE RESINS The compositions of the present invention comprise a polysiloxane resin in which at least one substituent group of the resin possesses delocalised electrone.

Polysiloxane resins are highly entangled polymeric siloxane systems. Entanglement is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional or difunctional silanes, or both, during the manufacture of the silicone resin. As is well understood in the art, the degree of entanglement that is required in order to result in a silicone resin will vary according to the specific silane units incorporated in the silicone resin. In general, silicone materials having a sufficient level of trifunctional and tetrafunctional siloxane monomer units, (and therefore, a sufficient level of entanglement) so that they dry to a rigid, or hard film, are considered as silicone resins.

Preferred alkyl groups include, but are not limited to, methyl, ethyl, propyl isopropyl and butyl. Most preferred are methyl, ethyl and propyl. As used herein, the term "alkaryl" represents a substituent comprising an alkyl portion and an aryl portion, wherein the alkyl portion is attached to the siloxane resin. As used herein, the term "arylalkyl" means a substituent comprising an aryl portion and an alkyl portion, wherein the aryl portion is attached to the desiloxane resin. Silicone materials and silicone resins in particular, suitably they can be identified according to a shorthand nomenclature system, well known to those skilled in the art as "MDTQ" nomenclature. Under this system, the silicone is described according to the presence of several units of monomer deiloxane, which form the silicone. In summary, the symbol M denotes the monofunctional unit (CH3) 3SiOo.5; D denotes the functional unit (CH3) 2SiO; T denotes the trifunctional unit (CH3) s, or? .5; and Q denotes the quatri or tetra-functional unit SiO2.
