Description

Technical field

The present invention relates to conditioning shampoo compositions comprising pentaerythritol ester oil, a detersive surfactant, and supplementary conditioning agents.

BACKGROUND OF THE INVENTION

Human hair is stained by its contact with the environment and the skin fat secreted by the scalp. Dirty hair makes hair look dirty or greasy and unattractive. Soiling your hair requires regular shampooing.

Shampoo cleans the hair by removing excessive soiling and skin fat. However, shampooing can leave the hair moistened, tangled, and generally uneditable. When the hair is dry, it often remains in a dry, coarse, matt or curly state due to the removal of natural hair oils and other natural conditioning and moisturizing ingredients. Hair after drying may further remain at elevated levels of static electricity, which may interfere with combing and result in a condition commonly described as rising hair.

Various approaches have been developed to alleviate these problems after shampooing. These approaches range from the use of a hair conditioner to shampooing, such as products that remain on or are washed out, to hair conditioning shampoos that attempt to both cleanse and condition the hair in one product.

A wide variety of conditioning active ingredients have been proposed to provide shampoo cleansing bases. However, many of these active ingredients have drawbacks in that they leave the hair with the appearance of soiling or waxing or interfere with the cleansing effects of the shampoo.

The formation of coacervate in the shampoo formulation is known to be suitable for obtaining hair conditioning effects. The use of cationic polymers for the formation of coacervates is known in the art, for example in PCT publications WO90 / 08787 and WO95 / 01152. However, these shampoo compositions are unable to provide a satisfactory conditioning effect when the hair is wet.

According to the foregoing, there is a need to provide a conditioning composition that can provide an improved conditioning effect when the hair is wet while not interfering with the cleansing performance nor leaving the hair with a negative appearance when it dries. Specifically, there is a need to provide the softness and ease of combing when the hair is wet, as well as to provide long-lasting moisturizing, smoothness and control of hair styling when the hair is dry, while not letting it look greasy.

All the advantages and benefits of the present invention have nothing in the art.

SUMMARY OF THE INVENTION

The present invention relates to a conditioning shampoo composition comprising

1) pentaerythritol ester oil of the following formula I,

R (I) wherein R ¹ , R ² , R ³ and R ⁴ are independently branched, straight, saturated or unsaturated alkyl, aryl and alkylaryl groups having 1 to 30 carbons,

(2) a cleaning surfactant selected from the group consisting of anionic surfactants, ampholytic surfactants, nonionic surfactants, and mixtures thereof;

(3) an additional conditioning agent selected from the group consisting of silicone compounds, cationic polymers, high melting compounds and mixtures thereof; and

4) an aqueous carrier.

These and other features, aspects, and advantages of the present invention will be readily apparent to those skilled in the art when reading the present disclosure.

Although the exact description ends with the claims that specifically disclose and clearly claim the invention, it is believed that the present invention will be better understood from the following description.

All references cited herein are incorporated by reference in their entirety. Citation of any reference is no more than an admission relating to determining its availability in the preceding parts in relation to the claimed invention.

The term "comprising" here means that additional steps and other ingredients that do not affect the end result may be added. The term includes "consisting of" and "consisting essentially of".

All percentages, parts and ratios are based on the total weight of the shampoo compositions of the present invention, unless otherwise indicated. Since all of these weights are based on the above ingredients, they are based on the level of the active ingredient and therefore do not include carriers or by-products that may be included in commercially available materials.

The aspects and embodiments of the present invention disclosed herein have many advantages. For example, the conditioning shampoo compositions of the present invention provide softness and ease of combing when the hair is wet and provide long-lasting moisturizing, smoothness, and control of hair compliance when the hair is dry, but does not leave an impression of grease.

Pentaerythritol ester oils

The hair conditioning composition of the present invention comprises pentaerythritol ester oil. Pentaerythritol ester oils useful herein are those which are insoluble in water, have a relative molecular weight of at least 800, and are in liquid form at 25 ° C. The term water insoluble, as used herein, means that the compound is not significantly soluble in water at 25 ° C when the compound is mixed with water at a concentration of above 1.0%, preferably above 0.5%, temporarily dispersed to form a continuous colloid in water, then rapidly separated from the water to form two phases.

Here, the pentaerythritol ester oil provides conditioning effects such as moisturizing, smoothness and control of hair conditionability when the hair dries and yet does not leave the hair feeling greasy. It is believed that the water-insoluble oily material is generally capable of retaining on the hair. Without wishing to be bound by theory, it is believed that, due to its bulkiness, the pentaerythritol ester oil covers the hair surface and, as a result, this pentaerythritol ester oil reduces hair friction while imparting fineness and control of hair styling. It is also believed that since it has some hydrophilic groups, the pentaerythritol ester oil provides moisturizing even when it is liquid, it does not give the hair an impression of grease. The pentaerythritol ester oil is stable under normal conditions of use and storage.

The pentaerythritol ester oil is preferably present in the composition in an amount of 0.1 to 20 wt. %, preferably 0.2 to 10 wt. %, more preferably 0.5 to 5 wt. %.

References describing suitable nonvolatile dispersion silicone compounds are disclosed in U.S. Pat. No. 2,826,551 to Geen, U.S. Pat. No. 3,964,500, Drakoff, issued Jun. 22, 1976, U.S. Pat. No. 4,364,837, Pader and GB patent no. Woolston. Silicon Compounds, distributed by Petrarch Systems, Inc, 1984, provides a comprehensive, though not the only list of suitable silicone compounds.

Another non-volatile dispersion silicone which may be particularly suitable is silicone rubber. The term "silicone rubber, as used herein," means a polyorganosiloxane material having a viscosity of greater than or equal to 1 m ² · s ^-1 (1 000 000 centistokes) at 25 ° C. It is understood that the silicone rubbers described herein may also overlap with the silicone compounds described above. This overlap is not to be construed as limiting any of these materials. Silicone rubbers are described by Petrarch et al., Including U.S. Pat. No. 4,152,416, Spitzer et al. published May 1, 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York, Academic Press 1968. Silicone rubbers are also described in General Eletric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54, and SE 76. Silicone rubbers typically have a relative molecular weight of greater than 200,000 to 1,000,000. Particular examples include poly (dimethylsiloxane), copoly copolymers (dimethylsiloxane / methylvinylsiloxane), copolymers (dimethylsiloxane / diphenylsiloxane / methylvinylsiloxane), and mixtures thereof.

Silicone resins, which are highly crosslinked polymeric siloxane systems, are also suitable. Crosslinking is accomplished by incorporating trifunctional and tetrafunctional silanes into monofunctional or bifunctional silane, or both, during the production of the silicone resin. As is well known in the art, the degree of crosslinking required to obtain the resulting silicone resin varies according to the particular silane units incorporated into the silicone resin. In general, those silicone materials having a sufficient level of trifunctional siloxane monomer unit and hence a sufficient level of crosslinking to dry to a solid or hard film are considered to be silicone resins. A measure of the level of crosslinking of a particular silicone material is the ratio of oxygen atoms to silicon atoms. Silicone materials having an oxygen atom to silicon atom ratio of at least 1.1 here will generally be silicone resins. The ratio of oxygen to silicon atoms is preferably at least 1.2: 1.0. Silanes used in the production of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl- and methylvinylchlorosilanes and tetrachlorosilane, with methylsubstituted silanes being most commonly used. Preferred resins are offered by General Elektric as GE SS4230 and SS4267. Commercially available silicone resins are generally supplied in dissolved form as a low viscosity volatile or nonvolatile silicone fluid. Silicone resins for use herein should be supplied and incorporated into the composition of the present invention in a soluble form as will be readily apparent to those skilled in the art. Without wishing to be bound by theory, it is believed that silicone resins can increase hair coverage by other silicone compounds and can significantly increase hair shine through a high refractive index.

Other suitable silicone resins are silicone resin powders, such as the material listed under CTFA designation as polymethylsilsequioxane, which is commercially available as Tospearl ™ from Toshiba Silicones.

A method for producing these silicone compounds can be found in the Encyclopedia of Polymer Science and Engineering, Volume 15, second edition, pages 204-308, John Wiley & Sons, Inc., 1989.

Silicone materials, and especially silicone resins, can be conveniently identified by an abbreviated nomenclature system well known to those skilled in the art as MDTQ nomenclature. In this system, silicone is described according to the presence of various siloxane monomer units that form silicone. Briefly, M denotes monofunctional (CH ₃ ) ₃ SiO 5, D denotes bifunctional (CH ₃ ) 2 SiO, T denotes the trifunctional unit (CH ₃ ) SiO _15, and Q denotes the tetrafunctional unit S1O2. Superscripts of unit symbols, e.g. M ', D', T 'and Q' designate substituents different from the methyl group and must be specifically defined for each occurrence thereof. Typical alternative substituents include groups such as vinyl, phenyl, amino, hydroxy, and the like. The molar ratios of the various units, whether as subscripts in the symbols indicating the total number of each type of unit in the silicone or its diameter, or specifically designated ratios in combination with the molecular weight, complete the description of the silicone material in the MDTQ system. Higher relative molar amounts of T, Q, T 'and / or Q' to D, D 'M and / or M' in the silicone resin indicate a high level of crosslinking. However, as discussed above, the overall level of crosslinking can also be indicated by the ratio of oxygen to silicon.

Preferred silicone resins for use herein are MQ, MT, MTQ, MQ and MDTQ resins. Thus, a preferred silicone substituent is methyl. Particularly preferred are MQ resins wherein the M: Q ratio is 0.5: 1.0 to 1.5: 1.0 and the average relative molecular weight of the resin is 1000 to 10,000.

Method of preparation

The shampoo formulations of Examples 1 to 6, as shown above, can be made by any conventional method well known in the art. A preferred method is described below.

Pentaerythritol ester oils, cleaning surfactants, and, if present, cationic polymers and high melting point compounds are dissolved and dispersed in water to form a homogeneous premix at elevated temperature, e.g. above 70 ° C. If a silicone compound is present, a silicone emulsion is made which includes a silicone compound, a small amount of a cleaning surfactant, and a portion of water. The remaining components can be added either to the premix or in the last step of the process. The premix and the remaining ingredients, if present, are thoroughly mixed at elevated temperature and then pumped through a mixing calender and then through a heat exchanger to cool to ambient temperature. Perfume and, if present, inorganic salts and silicone emulsions are added to this cooled mixture. Alternatively, the remaining ingredients may be added at this step.

The embodiments described and represented by the preceding examples have many advantages. For example, they can provide the hair with softness and ease of combing when the hair is wet, as well as providing long-lasting moisturizing, softness and control of hair styling when the hair is dry without leaving hair greasy.

It is to be understood that the examples and embodiments described herein are for illustrative purposes only, and that various modifications or changes will be suggested by those skilled in the art without departing from its spirit and scope.
