BACKGROUND of INVENTION AND prior art

Modified alkylsilane have found application in many cosmetic products, especially as humidifiers in products for skin care and as liabilitiesa additive in creams and lotions from the sun.

In the patent WO91/09586 describes how certain polymethylphenylsiloxane can give your hair extra Shine and luster and gentleness and softness in the same way as polydimethylsiloxane, but which create a feeling that the hair outwardly less heavy and greasy. It is believed that these polymethylphenylsiloxane give hair more volume, fluffiness and softness thanks polydimethylsiloxane liquids.

The authors of the present invention have observed that the modified alkylsilane of this type, as described in the patent WO91/09586, tend strongly deposited on the hair when used in a regular basis tools for hair care. Excessive deposition entails a reduction in the amount of hair that is perceived by many buyers is not desirable.

The authors of the present invention have found that these problems can be is solved by combining emulsified particles modified alkylsilane with emulsified particles of a particular silicone, not containing alkyl modifying groups.

(i) emulsified particles of the modified alkylsilane,

and

(ii) emulsified particles of silicone, alkyl not containing modifier group.

Compositions according to the invention provide an effective conditioning hair, considerably hair without overloading it.

Suspendisse agent will, in General, be present in the shampoo compositions of the invention in amounts of from 0.1 to 10%, preferably from 0.5 to 6%, more preferably from 0.9 to 4% of a suspending agent by weight of the total composition.

Additional conditioning agents

Compositions of the invention can contain additional conditioning agents in addition to the substances described above, in order to optimize the advantages of wet and dry conditioning.

Examples of additional conditioning agents are volatile silicones.

The term "volatile"as used here, means that the substance has a vapor pressure under normal conditions is equal to or higher than that of ethanol.

Volatile silicones suitable for use in compositions of the present invention include both linear and cilice is such silicones. Linear volatile silicones will generally have viscosity 5 mm²s^-1(CST) or less at 25°C., while the cyclic volatile silicones are, as a rule, have a viscosity of 10 mm²s^-1or less at 25°C.

Suitable cyclic volatile silicones include Cyclopentasiloxane, such as cycloalkylcarbonyl and cycloalkylcarbonyl, where alkyl and CNS groups contain From₁-C₈alkyl groups.

The General formula of suitable cyclic volatile silicones is the following:

[(R₁)(R₂Si-O-]_n,

in which n is from 3 to 7, and R₁and R₂independently selected from alkyl With₁-C₈, aryl (in particular phenyl) and alkaryl (for example, C₁-C₈substituted aryl).

Preferably, R₁and R₂are₁-C₂alkilani. Most preferably, R₁and R₂are₁the alkyl (such substances are CFTA designation cyclomethicone).

Preferably, n is equal to the value of 4 to 6, most preferably 4 to 5.

Specific examples of preferred cyclic volatile silicones are octamethylcyclotetrasiloxane, dimethylcyclopentane and their mixture.

Linear volatile silicones include polyorganosiloxanes, such as polydiorganosiloxane and polyalkylacrylate.

The General formula for the appropriate linear volatile silicones are the following:

(R₁)(R₂)(R₃Si-O-[Si(R₄)(R₅)O]_nSi(R₆)(R₇)(R₈),

in which n is equal to values from 1 to 7, and R₁, R₂, R₃, R₄, R₅, R₆, R₇and R₈are₁-C₂alkilani. More preferably, R₁, R₂, R₃, R₄, R₅, R₆, R₇and R₈was₁the alkyl (such substances are CFTA designation Dimethicone).

Silicones of the above described types of commercially available, for example, from Dow Corning Corporation as DC 244, 245, 344, 345 and 200.

Other optional ingredients

The composition of the present invention may contain other ingredients to improve and/or consumer acceptance. Such components include fragrances, dyes and pigments, substances that regulate the pH of the medium, the substance that gives the pearl effect and cloud emulsions, viscosity modifiers, preservatives and natural nutrients for hair, such as botanicals, fruit extracts, sugar derivatives and amino acids.

Method of use

The compositions of this invention are primarily intended for topical application to the hair and/or scalp of a person in compositions for washing, in order to better t the VA hairline, such as moisturizing hair, smoothness, softness, flexibility, manageability and Shine.

Compositions presented in the present invention, generally are conditioning compositions for hair care (usually after shampooing) with subsequent flushing.

Or compositions presented in the invention can be aqueous compositions shampoos used by massaging them into the hair, followed by flushing with clean water before drying the hair. Optionally, a separate conditioning composition can be used after washing to drying, but this may not be necessary, as it is assumed that the composition of water shampoo invention provides both cleansing and conditioning the hair.

This invention is further illustrated by reference to the following, non-limiting examples in which all percentages are mass of the total weight, except in those cases where specified. Examples of the invention are numbered. Comparative examples not in accordance with this invention) are indicated by letters.

EXAMPLES

Composition for conditioning hair was prepared having ingredients as shown in the following table 1:

The compositions of table 1 were evaluated for their ability to straighten the hair and on the deposition of silicone on the hair. To study hair straightening test composition is applied to hair lining with the hair standard weight and volume. Make pictures as soon as these pads are dried under controlled conditions. Experts are asked to make pairwise comparisons of the degree of discrepancy n the clutches of these photos with the sample. Done 36 comparisons for each test composition.

The deposition of silicone was measured by x-ray fluorescence spectroscopy.

Also measured the amount of hairpieces after processing the test compositions.

The results of the above analyses are presented in the following table 2:

For mismatch scoring for the hair of the smallest ball score is preferred. It is also desirable to avoid excessive levels of silicone deposition on hair. From the above data you can see how high levels of silicone deposition correlate with reduced dimensions of the overlay.

Example 1 (according to the invention) and Examples A-C (comparative) all used a modified alkylsilane⁽³⁾at various activity levels. Within these series Example 1 and Example To give the best (i.e. lowest) discrepancy score for the hair. However, the Example demonstrates junk 11-fold increase in the deposition of silicone on the hair and significantly reduces the volume of the pads, as compared with Example 1.

Example 2 (according to the invention) and examples D-F (comparative) all use a modified alkylsilane⁽⁴⁾at various activity levels. Within these series Example 2 and Example F give the best (i.e. lowest) discrepancy score for the hair. However, the Example F shows unwanted 24-KRA is increase of deposition of silicone and significantly reduces the volume of the pads, compared with Example 2.

Comparative Example G gives this level of deposition of silicone, which is approximately equal to the level of Example 2. However, the characteristics of the Example G mismatch ball estimates for the hair significantly inferior to those same characteristics of Example 2.

Therefore, the compositions of this invention provide excellent balance alignment hair, deposition of silicone and the amount of hair in comparison with comparative examples.
