Description

Personal care composition comprising a cleansing phase and a benefit phase

field of invention

The present invention relates to personal care compositions suitable for use on mammalian skin and hair. These compositions comprise a cleansing phase and at least one benefit phase selected from fatty compound gel networks, hydrophobic gel networks, hydrophobic compounds in fatty compound gel networks Gel network, aliphatic compound gel network in hydrophobic gel network, or silicone or silicone gel. These products serve to provide a multi-phase cleansing composition that is packaged in a hands-on manner while remaining stable and providing improved in-use and post-use hair and skin benefits.

Background of the invention

Cleansing compositions are known in the art that may contain detersive surfactants and cationic polymers to enhance deposition of conditioning oils, such as silicone oils, thereby imparting conditioning or smoothing properties to the surfaces they treat. However, these conditioning oils are limited in the range of physical, optical and aesthetic benefits they provide. Rinse-off conditioning compositions comprising cationic surfactants and fatty alcohols are also known. These compositions also contain various oils and silicone compounds to provide surface smoothness, frizz control and detangling benefits. Conditioners for hair have the specific viscosity required for such products. These products are based on a combination of surfactants (usually quaternary ammonium compounds) and fatty alcohols. This combination produces a gel network structure which provides the desired rheological properties to the composition.

Typically, separate shampoo and conditioner products are used by those with higher hair conditioning needs. The hair conditioning benefits provided by conditioning-shampoos, commonly known as 2-in-1 shampoos, are not always sufficient. Treatment with individual conditioners provides excellent wet and dry hair conditioning benefits. The gel network structure of the hair conditioner is capable of producing unique in-use and post-use wet hair conditioning benefits.

There has long been a need to deliver conditioner gel network benefits from a bottle of hair cleansing-conditioning composition. Typically, when the conditioning gel network is added to a detersive/anionic surfactant containing hair cleansing composition, both the conditioning gel network and the rheological properties of the cleansing composition are disrupted. This undesired interaction between the anionic cleansing phase and the conditioning gel network has an adverse effect on the lathering effect of the product.

One attempt at providing hair conditioning and cleansing benefits from personal cleansing products while maintaining gel network structure and lather is dual chamber packaging. These packs contain separate cleansing and conditioning compositions and can be co-dispensed in one or two strands. Separate conditioning and cleansing compositions are maintained in a physically separate and stable state during long-term storage and immediately prior to application, and then mixed at or after dispensing to provide conditioning and cleansing benefits from a physically stable system. While such dual-chamber delivery systems may provide improved conditioning benefits compared to using conventional systems, consistent and uniform performance is often difficult to achieve due to the uneven distribution ratio between the cleansing and benefit phases from these dual-chamber packages . Furthermore, these packaging systems add considerable cost to the finished product.

Accordingly, there remains a need for a personal cleansing composition that provides cleansing and improved hair conditioning benefits delivered from one product. There also remains a need for a personal cleansing composition comprising two phases in physical contact which is stable over time. Accordingly, it is an object of the present invention to provide a multi-phase hair cleansing composition comprising a cleansing phase and a benefit phase (e.g., conditioning, styling, hair shine enhancement, hair coloring, hair moisturizing, hair health enhancement, etc.), the combination The composition provides improved in-use and post-use hair benefits while being packaged in a physical contact manner while remaining stable.

Summary of the invention

The present invention relates to multiphase personal care compositions comprising a cleansing phase and at least one benefit phase selected from the group consisting of a fatty compound gel network, a hydrophobic gel network, a hydrophobic gel network in a fatty compound gel network, An aliphatic compound gel network, or a silicone or silicone gel in a hydrophobic gel network. These products are used to provide multi-phase cleansing compositions that are packaged in a physical contact manner while remaining stable and providing improved in-use and post-use hair and skin benefits. In the present invention, the cleansing phase, the benefit phase, or both the cleansing and benefit phases can be visually transparent.

The present invention also relates to a method of using the multi-phase personal care composition.

Detailed description of the invention

The present invention relates to multi-phase personal care compositions suitable for use on mammalian hair or skin comprising a cleansing phase and a benefit phase. It has surprisingly been found that multiphase liquid cleansing compositions comprising a cleansing phase and an additional benefit phase can be formulated to provide improved hair benefits during and after application while also providing excellent hair conditioning and cleansing benefits Effect wherein the cleansing phase and additional benefit phase are packaged in physical contact while remaining stable. It has been found that the above compositions can be formulated with sufficiently high levels of benefit agents without compromising the lather and stability of the product. It has been discovered that multi-phase personal care compositions with enhanced stability can be formulated through density matching of the cleansing and benefit phases, and the incorporation of structurants in the cleansing phase.

The essential components of the multiphase personal care compositions are described below. Also included are non-exclusive descriptions of various optional and preferred components that may be used in embodiments of the present invention. While the specification concludes with claims particularly pointing out and distinctly claiming the invention, it is believed the invention will be better understood from the following description.

Herein, the term "weight percent" may be expressed as "wt.%".

All molecular weights used herein are weight average molecular weights expressed in grams per mole unless otherwise indicated.

The term "charge density" as used herein refers to the ratio of the number of positive charges on the monomeric units making up the polymer to the molecular weight of the monomeric units. The charge density multiplied by the polymer molecular weight determines the number of positively charged sites on a given polymer chain.

Herein, "comprising" means that other steps and other ingredients which do not affect the end result can be added. This term includes the terms "consisting of" and "consisting essentially of". The compositions and methods/processes of the invention can comprise, consist of, or consist essentially of the essential ingredients and limitations described herein, as well as any additional or optional ingredients, components, steps or limitations described herein.

The term "visually clear" as used herein means that the composition has a transmittance greater than 60%, preferably greater than 80%. The clarity of the composition is determined using ultraviolet/visible (UV/VIS) spectrophotometry, which measures the absorption and transmission of UV/VIS light by sampling. It has been proven that a light wavelength of 600 nm is sufficient to characterize the transparency of cosmetic compositions. Typically, it is best to follow the specific instructions for use associated with the particular spectrophotometer used. Typically, the process of determining percent transmission begins with setting the spectrophotometer to 600 nm. Then, run a calibration "blank" to calibrate the reading to 100% transmission. The test sample is then placed in a cuvette designed to fit that particular spectrophotometer, and the percent transmission is measured with the spectrophotometer at 600 nm.

The terms "multiphase" and "multiphase" as used herein mean that at least two phases occupy separate and distinct physical spaces in the packaging in which they are stored, but are in direct contact with each other (i.e., they are not separated by a barrier, and They are not emulsified). In a preferred embodiment of the present invention, a "multi-phase" personal care composition comprising at least two phases is present in a container in visually distinct patterns. The pattern results from the mixing or homogenization of the "heterogeneous" composition. These patterns include, but are not limited to, the following examples: striped, marbled, straight, interrupted stripes, crackled, mottled, veined, tufted, speckled, geometric, mottled banded, spiral, swirly, aligned, variegated, textured, grooved, ridged, wavy, sinusoidal, helical, twisted , curved, looped, striped, striped, contoured, heterogeneous, lacy, interwoven or braided, basketweave, speckled, and tessellated .

Unless otherwise indicated, the term "ambient conditions" as used herein relates to ambient conditions of 101 kPa (one (1) atmosphere), 50% relative humidity and 25°C.

Unless otherwise indicated, the term "stable" as used herein refers to a composition that does not change significantly over time in the visible pattern or arrangement of phases at different locations in the package when left in contact with ambient conditions for a period of at least about 180 days. Furthermore, it means that no separation, creaming or precipitation occurs. "Separate" means that the intact distribution of visually distinct phases is disrupted such that a larger region of at least one phase aggregates until the equilibrium distribution ratio of two or more compositions with respect to each other is disrupted.

Unless otherwise indicated, the term "personal care composition" as used herein relates to compositions of the present invention, wherein said compositions are intended to include only those compositions for topical application to the hair or skin, and in particular excluding those primarily intended for other applications ( such as hard surface cleaning, fabric or clothing cleaning, and similar other applications) that are not primarily intended for topical application to the hair or skin.

An optional ingredient that may be included in the silicone conditioning agent is a silicone resin. The silicone resins are highly crosslinked polysiloxane systems. The crosslinking is introduced by incorporation of trifunctional and tetrafunctional silanes together with monofunctional or difunctional silanes or both during silicone resin production. As understood in the art, the degree of crosslinking required to obtain a silicone resin will vary depending on the particular silane units incorporated into the silicone resin. In general, polysiloxane materials having sufficient amounts of trifunctional and tetrafunctional siloxane monomer units (and thus, sufficient levels of crosslinking) to form rigid or hard films when dry are considered polysiloxanes. oxane resin. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking of a particular silicone material. The silicone resins of the present invention are generally silicone materials having at least about 1.1 oxygen atoms per silicon atom.

Silanes used to make silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, methylvinyl -Chlorosilanes, as well as tetrachlorosilanes, methyl-substituted silanes are the most commonly used. Preferred resins are GESS4230 and SS4267 supplied by General Electric. Commercially available silicone resins are generally supplied in dissolved form in low viscosity volatile or nonvolatile silicone fluids. It will be apparent to those skilled in the art that the silicone resins suitable for use herein should be provided in such dissolved form and incorporated into the compositions of the present invention. The silicone resin enhances the deposition of silicone on the hair and enhances the shine of hair with high refractive index volume.

Background information on siloxanes and their preparation, including chapters discussing silicone fluids, silicone gums, and silicone resins, can be found in Encyclopaedia of Polymer Science and Engineering, Vol. 15, 2nd Edition, 204- 308 pages, John Wiley & Sons, Inc., 1989.

Silicone materials, and especially silicone resins, are conveniently identified by a shorthand nomenclature well known to those skilled in the art, namely the "MDTQ" nomenclature. Under this system, siloxanes are described in terms of the presence of the various siloxane monomer units that make up the siloxane. Briefly, the symbol M represents the monofunctional unit (CH ₃ ) ₃ SiO _0.5 ; D represents the difunctional unit (CH ₃ ) ₂ SiO; T represents the trifunctional unit (CH ₃ ) SiO _1.5 ; Q represents the quadruple or tetrafunctional unit SiO ₂ . Major parts in the unit symbols such as M', D', T' and Q' represent substituents other than methyl, with specific definitions for each case. Typical other substituents include groups such as vinyl, phenyl, amino, hydroxyl, and the like. The molar ratio of each unit, or the total number (or its average number) of each type of unit in the polysiloxane is indicated by the symbol subscript, or expressed in a specific ratio and combined with molecular weight, so that the polysiloxane can be adjusted according to the MDTQ system. Description of alkanes. A higher molar amount of T, Q, T' and/or Q' relative to D, D', M and/or M' in a silicone resin means a higher level of crosslinking. However, the overall degree of crosslinking can also be expressed by the ratio of oxygen to silicon.

The silicone resins useful herein are preferably MQ, MT, MTQ, MQ and MDTQ resins. Accordingly, the preferred siloxane substituent is methyl. Especially preferred are MQ resins wherein the M:Q ratio is from about 0.5:1.0 to about 1.5:1.0 and the resins have an average molecular weight of from about 1000 to about 10,000.
