Description

COMPOSITIONS FOR TREATING HAIR OR SKIN

TECHNICAL FIELD The present invention relates to compositions useful for treating hair or skin Specifically, these compositions are useful for delivering panthenol, and especially D-panthenol, to the hair or skm These compositions comprise panthenol, a polyalkyleneglycol having from 3 to about 12 repeating ethyleneglycol or propyleneglycol units, and a topical vehicle These compositions are useful as hair and skin conditioners

BACKGROUND OF THE INVENTION There exists a general need to provide compositions which are useful for treating the hair and skin to provide, for example, conditioning benefits Both hair and skin are related keratinous substances and are constantly subjected to environmental stresses such as low humidity, UV radiation, contact with with surfactants, and physical abrasion, and also to internal stresses shich are a consequence of the natural aging process Because of these stresses, the hair and the skin tend to loose their natural conditioning and moistunzing components and often appear rough, dry, and damaged Regarding the hair, it is often difficult to keep the hair from tangling after it is washed and to prevent the occurrence of fhzziness, split ends, and other undesirable effects Regarding the skin, it is often difficult to keep the skm lookmg and feeling smooth, supple, and moisturized Consequently, over the years, a wide vanety of materials have been used in an attempt to treat the hair and skm However, many conventional hair and skin conditionmg materials have drawbacks such as not bemg effective or longlasting, of bemg difficult to formulate, or of havmg negative aesthetic qualities

Panthenol is a material that has been used to treat both the hair and skm Panthenol is the alcohol form of vitamin B3, which is also knwon as pantothenic acid For example, U S Patent No 4,705,681, to Maes et al , issued November 10, 1987, discloses hair treatment compositions containing the combination of one part by weight of D-panthenol to nine parts by weight of D- panthenyl ethyl ether Compositions for providing superficial wound healing containing the combination of panthenol and zmc oxide are disclosed in H Weise et al , "Acceleration of Superficial wound Healing by Panthenol Zmc Oxide," Cosmetics and Toiletries, vol 103, pp 79-84, October 1988 The benefits that can be obtained from usmg panthenol in hair and skm care compositions, however, are not fully realized because panthenol is a relatively expensive ingredient that is difficult to formulate and deliver from a finished product composition Therefore, a need exists for developing formulation systems for efficiently and effectively delivering panthenol to the hair and skin.

It has suφrisingly been found in the present invention that the combination of panthenol and certain low molecular weight polyalkylene glycols, i.e polyethylene glycols or polypropylene glycols having from 3 to about 12 ethylene glycol or propylene glycol units, provides a highly effective and efficient, yet relatively economical system, for delivering panthenol to the hair or skin. It has been found that this combination of panthenol and polyalkylene glycol can be delived in a wide variety of nonlimiting product forms including hair conditioners, shampoos, mousses, gels, tonics, skin lotions, skin creams, and skin cleanser. It is therefore an object of the present invention to provide compositions for the treatment of hair or skin.

It is another object of the present invention to provide compositions containing panthenol in combination with a polyethyleneglycol or polypropylene glycol having from 3 to about 12 ethylene glycol or propylene glycol units. It is another object of the present inveniton to provide compositions which are useful for conditioning the hair or skin.

It is another object ofthe present invention to provide methods for treating hair or skin. These and other objects of this invention will become apparent in light of the following disclosure. SUMMARY OF THE INVENTION

(c). a topical vehicle, wherein the weight ratio of said polyalkylene glycol to panthenol is from about 40: 1 to about 1 :40.

The present invention also relates to methods for treating hair or skin with these compositions.

All percentages and ratios used herein are by weight of the total composition and all measurements made are at 25 C or ambient room temperature, unless otherwise designated. All weight percentages, unless otherwise indicated, are on an actives weight basis. The invention hereof can comprise, consist of, or consist essentially of, the essential as well as optional ingredients and components described herein.

DETAILED DESCRIPTION OF THE INVENTION It has been found in the present invention that the combination of panthenol and certain low molecular weight polyalkylene glycols, i.e polyethylene glycols or polypropylene glycols having from 3 to about 12 ethylene glycol or propylene glycol units provides compositions that are useful for treating the hair or skin. These compositions are highly effective and efficient for delivering panthenol to the hair or skin. These compositions can be formulated in a wide variety of product forms including hair conditioners, shampoos, mousses, gels, tonics, skin lotions, skin creams, skin clenasers, and the like.

The term "topical application," as used herein, means to apply or spread the compositions of the present invention to the hair or to the surface ofthe skin.

The term "leave-on," as used herein, means a composition that is intended to be applied to and left on the hair or skin.

The term "rinse-off," as used herein, means a composition that is applied to the hair or skin and is subsequently rinsed from the hair or skin.

The term "wipe-off," as used herein, means a composition that is applied to the hair or skin and is subsequently wiped from the hair or skin. The term "safe and effective amount," as used herein means an amount of the composition or components thereof sufficient to provide the desired benefit without causing undesired side effects or reactions.

The terms "cosmetically-acceptable" and "pharmaceutically-acceptable," as used herein, means that the compositions or components so described are of sufficiently high purity and are suitable for use in contact with human hair or skin without undue toxicity, incompatibility, instability, allergic response, and the like. PANTHENOL

The compositions of the present invention comprise panthenol. The compositions should comprise a safe and effective amount of panthenol. The compositions typically comprise from about 0.001% to about 1%, preferably from about 0.005% to about 0.5%, and more preferably from about 0.01% to about 0.25%, by weight ofthe total composition of panthenol.

Panthenol is the alcohol corresponding to pantothenic acid, the acid being a member of the B complex vitamins. Panthenol is also known as pantothenol and 2,4-dihydroxy-N-(3- hydroxypropyl)-3,3-dimethylbutanamide. The material can exist as stereoisomers, e.g., the D(+) form, the L(-) form, the racemate, and other mixtures of the D(+) and L(-) forms. The D(+) form, which is also known as dexpanthenol or D-panthenol, is related to the naturally occurring form of pantothenic acid. Without being limited by theory, it is believed that the D(+) form of panthenol is the active material that is useful for treating the hair or hair. In preferred embodiments, the compositions ofthe present invention comprise D(+) panthenol (hereinafter designated simply as "D- panthenol"). POLYALKYLENE GLYCOL

The compositions of the present invention comprise at least one polyalkylene glycol. The compositions typically comprise from about 0.01% to about 20%, preferably from about 0.05% to about 10%, and more preferably from about 0.1% to about 5%, by weight ofthe total composition of at least one polyalkylene glycol.

The polyalkylene glycols useful herein are those corresponding to the following formula:

In the preceding formula, R is selected from the group consisting of H, CH3, and mixtures thereof, preferably R is H. When R is H, the polyalkylene glycol is a polyethylene glycol, i.e. the polyalkylene glycol is composed of repeating units that are derived from ethylene glycol or ethylene oxide. When R is CH3, the polyalkylene glycol is a polypropylene glycol, i.e. the polypropylene glycol is composed of repeating units that are derived from propylene glycol or propylene oxide. In the preceding formula n is an integer from 3 to about 12, preferably from about 4 to about 8, and more preferably about 4. Without being limited by theory, it is believed that the polyethylene glycol helps to plasticize or soften the hair or skin and thereby aid in the delivery and penetration of the panthenol. It has been found that polyalkylene glycols having an n value of 2 are not useful for preparing compositions ofthe present invention.

In the present invention the following nomenclature is used to designate a polyalkylene glycol. For example, a polyethylene glycol in which n is 4 is designated "polyethylene glycol 4." A polyethylene glycol in which n is 6 is desingated "polyethylene glycol 6." Similar nomeclature is used for the pol propylene glycols.

WEIGHT RATIO OF POLYALKYLENE GLYCOL TO PANTHENOL In the compositions of the present invention invention the weight ratio of the polyalkylene glycol to the panthenol is from about 40: 1 to about 1:40, prefereably from about 20: 1 to about 1 :20, more preferably from about 10 : 1 to about 1 :10, and most preferably from about 10:1 to about 1: 1. TOPICAL VEHICLE The compositions of the present invention also comprise from about 50 to about 99.989%, preferably from about 75% to about 99.9%, and more preferably from about 80% to about 99% of a topical vehicle.

Silicone fluids hereof also include polyalkyl or polyaryl siloxanes with the following structure:

R

Si O Si 0 Si

wherein R is alkyl or aryl, and x is an integer from about 7 to about 8,000 may be used. "A" represents groups which block the ends ofthe silicone chains. The alkyl or aryl groups substituted on the siloxane chain (R) or at the ends of the siloxane chains (A) may have any structure as long as the resulting silicones remain fluid at room temperature, are hydrophobic, are neither irritating, toxic nor otherwise harmful when applied to the hair or skin, are compatible with the other components of the composition, are chemically stable under normal use and storage conditions, and are capable of being deposited on and of conditioning hair or skin.

Suitable A groups include methyl, methoxy, ethoxy, propoxy, and aryloxy. The two R groups on the silicone atom may represent the same group or different groups. Preferably, the two R groups represent the same group. Suitable R groups include methyl, ethyl, propyl, phenyl, methylphenyl and phenylmethyl. The preferred silicones are polydimethyl siloxane, polydiethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxane is especially preferred.

The nonvolatile polyalkylsiloxane fluids that can be used include, for example, polydimethylsiloxanes. These siloxanes are available, for example, from the General Electric Company in their Viscasil R® and SF96® series, and from Dow Corning in their Dow Corning 200® series.

The polyalkylaryl siloxane fluids that can be used, also include, for example, polymethylphenylsiloxanes. These siloxanes are available, for example, from the General Electric Company as SF1075® methyl phenyl fluid or from Dow Coming as 556 Cosmetic Grade Fluid®.

References disclosing suitable silicone fluids include U.S. Patent 2,826,551, Geen; U.S. Patent 3,964,500, Drakoff, issued June 22, 1976; U.S. Patent 4,364,837, Pader; and British Patent 849,433,'Woolston. All of these patents are incoφorated herein by reference in their entirety.

Another silicone conditioning material that can be especially useful in the compositions is insoluble silicone gum. The term "silicone gum", as used herein, means polyorganosiloxane materials having a viscosity at 25°C of greater than or equal to 1,000,000 centistokes. Silicone gums are described by Petrarch and others including U.S. Patent 4,152,416, Spitzer et al., issued May 1, 1979 and Noll, Walter, Chemistry and Technology of Silicones, New York: Academic Press 1968. The "silicone gums" will typically have a mass molecular weight in excess of about 200,000, generally between about 200,000 and about 1,000,000. Specific examples include polydimethylsiloxane, (polydimethylsiloxane) (methylvinylsiloxane) copolymer, poly(dimethylsiloxane) (diphenyl siloxane)(methylvinylsiloxane) copolymer and mixtures thereof. Preferably the silicone hair conditioning agent compnses a mixture of a polydimethylsiloxane gum, havmg a viscosity greater than about 1,000.000 centistokes and polydimethylsiloxane fluid havmg a viscosity of from about 10 centistokes to about 100,000 centistokes. wherein the ratio of gum to fluid is from about 30:70 to about 70.30, preferably from about 40:60 to about 60:40 The polydimethylsiloxane gum/polydimethylsiloxane fluid can be used alone or m a suitable carrier such as polysorbate 80

Also, a silicone resin can be mcluded in the silicone conditioning agent. Silicone res s are highly crosslinked polymeric siloxane systems The crosslinking is introduced through the incoφoration of trifunctional and tetrafunctional silanes with monofunctional or difunctional, or both, silanes dunng manufacture of the silicone resin. As is well understood in the art, the degree of crosslinking that is required in order to result tn a silicone resin will vary according to the specific silane units incoφorated into the silicone resin, ln general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units (and hence, a sufficient level of crosslinking) such that they dry down to a rigid, or hard, film are considered to be silicone resms The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen: silicon atoms is at least about 1.2: 1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyi-, diphenyl-, methylphenyl-, monovinyl-, and methylvinyl-chlorosilanes, and tetrachlorosilane, with the methyl-substituted silanes bemg most commonly utilized. Preferred resms are offered by General Electnc as GE SS4230® and SS4267®. Commercially available silicone resms will generally be supplied in a dissolved form in a low viscosity volatile or nonvolatile silicone fluid. The silicone resms for use herein should be supplied and incoφorated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art.

Another optional silicone conditioning agent is a volatile silicone solvent The volatile silicone allows for easier and more even dispersion of silicone gums and resins in the compositions. The silicones can be either cyclic or linear polydimethyl siloxanes. The number of silicon atoms in the cyclic silicones is from about 3 to about 7, most preferably 4 or 5. These materials are also known as cyclomethicones. Linear polydimethyl siloxanes useful in the present invention generally contain from about 3 to about 9 silicon atoms and have the general formula:

(CH₃)3Si-0-[Si(CH₃)2θ]_rn-Si(CH3)3

wherein m= 1-7.

Volatile silicone solvents of the above described types are widely available, e.g. from Dow Coming as 344, 345 and 200 Fluids®: Union Carbide as Silicone 7202 and 7158®;and Stauffer Chemical as SWS-03314®.
