ABSTRACT:
BACKGROUND OF THE INVENTION
Using hair fixatives in hair styling products to afford hold and control benefits to hair is well known. Hair styling product is applied to hair which is then treated with heat through the use of a blow dryer or a curling iron, for example. This type of treatment has been termed heat styling.
Unfortunately, heat styling only affords the consumer, styling, control, and hold benefits. Hair which has only been stiffened by such treatment is not always desired by the consumer. It is an object of the present invention to provide a hair styling composition which can be used for the heat styling of hair, but which also conditions the hair after such heat styling.
It is another object of the present invention to provide a hair styling composition which can be used for the heat styling of hair, but which also provides a hair softening and a hair bodifying benefit.
The following patents and publications are related to the field of the invention.
U.S. Pat. No. 5,756,106 discloses a hair care composition for treatment of hair before heat styling comprising a discrete first composition having at least one moisture holding ingredient, an emulsifier, and an ingredient which is a salt that helps break the emulsion after use, and a discrete second composition having at least one lubricant.
U.S. Pat. No. 5,968,495 discloses relatively high VOC hair styling compositions which provide good style retention without unacceptable stickiness or stiffness. The compositions comprise from about 0.01% to about 20% of a hair styling polymer, and from about 0.5% to about 95% of a carrier comprising:
(i) from about 0.5% to 55% of the carrier of a first solvent selected form water, water soluble organic solvents, other organic solvents; and
(ii) from about 40% to 95% by weight of the carrier of C

SUMMARY OF THE INVENTION
The invention relates to dual phase hair styling compositions which afford hair style, control and hold benefits, while at the same time providing hair conditioning, softening and bodifying benefits.
The hair styling compositions of the invention comprise dual-layers or phases which are shaken or mixed just prior to use to form a single-phase composition that is applied often to wet hair, which is then heated in a heat styling procedure. The composition returns to its dual-layer appearance an hour or more after use.
The first layer is a hydro-alcoholic layer containing hair fixatives in order to supply the desired hold and control and styling benefits. The second layer is anhydrous and comprises a volatile silicone such as a volatile cyclosiloxane like cyclomethicone; or a volatile linear dimethylsiloxane such as dimethicone. These silicones deliver conditioning benefits. The second layer may also be a volatile hydrocarbon.
Another aspect of the invention is to provide a hair styling and conditioning composition which affords, in storage, a pleasing dual-phased appearance.
Another aspect of the invention is to provide a method for styling and conditioning hair which comprises contacting said hair with a composition of the invention followed by applying heat to said hair with a heating appliance.
DETAILED DESCRIPTION OF THE INVENTION
Unless indicated otherwise, as used herein, % means weight %. As used herein the term “volatile” refers to materials that are liquid under ambient conditions and have a vapor pressure as measured at 25° C. of at least about 0.01 mm Hg, typically from about 0.01 mm Hg to 6.0 mm Hg. The starting materials set forth herein are either known or can be prepared in accordance with known methods.
The invention relates to hair styling and conditioning compositions, which are for use in heat styling hair, and which are dual phased in storage, and upon shaking or mixture becomes one-phased, and thereafter return to dual phase; wherein said composition comprises:
(a) a hydroalcoholic phase comprising at least one hair fixative; a salt which functions to break the emulsion made when the composition is shaken; and an emulsifier which functions to keep the fragrance solubilized in the hydro alcoholic phase; and
(b) an anhydrous phase comprising a volatile silicone or a volatile hydrocarbon, or mixtures thereof.
More specifically, the compositions of the invention comprise:
(a) from about 50% to about 95% of a hydroalcoholic phase which comprises:
(i) about 40% to about 90% of the total composition of water;
(ii) about 0.1 to about 15%, of the total composition of monohydric alcohol; and
(iii) about 0.01 to about 10.0%, or more preferably about 2 to about 5% of a hair fixative; and
(iv) a salt
(v) and an emulsifier;
(b) an anhydrous phase which comprises about 5% to about 50% of a volatile silicone or selected from the group consisting of dimethicone, cyclomethicone, and mixtures thereof, or a volatile hydrocarbon selected from the group consisting of isododecane, isohexadecane, and C13-C14 isoparaffin.
The hydroalcoholic phase is present at a most preferred range of about 65% to 85%.
The anhydrous phase is present at a most preferred range of about 35% to about 15%.
What follows now is a description of the ingredients which are included in the compositions of the invention.
Hydroalcoholic Phase
The hydroalcoholic phase of compositions of the invention comprises water and a monohydric alcohol.
Monohydric Alcohol
The monohydric alcohol that is used in compositions of the invention is a C
1
to C
4
monohydric alcohol. The monohydric alcohol is more preferably selected from the group consisting of ethanol, propanol, and butanol—most preferably ethanol.
A function of the monohydric alcohol in compositions of the invention is to solubilize the hair fixative in the hydroalcoholic phase.
Hair Fixative
The composition of the present invention comprises a hair fixative which can be a hair styling polymer for providing stylability to the hair. Hair styling polymers posses adhesive properties such that they are capable of shaping or styling the hair, and should be removable by shampooing or rinsing the hair. One or more hair styling polymers may be used. The total amount of hair styling polymer is generally from about 0.01% to about 10%, preferably from about 0.1% to about 5%, more preferably from about 2% to about 5%. A variety of hair styling polymers are suitable in the present invention. Particular polymers will be selected by the skilled artisan considering the solubility of the polymer in the composition and the ionicity of the composition
Suitable hairstyling polymers are those which are soluble or dispersible (preferably micro dispersible) in the carrier described herein in the weight ratios employed in the composition.
Hair styling polymers include silicone-containing hair styling copolymers such as graft and block copolymers of silicone with a non-silicone adhesive polymer; sulfur-linked silicone containing copolymers; and non-silicone-containing hair styling polymers.
Non-silicone-containing hairstyling polymers include nonionic, anionic, cationic, and amphoteric polymers, and mixtures thereof. When used, the non-silicone-containing hair styling polymers are preferably present in a combined amount of from about 0.01% to about 10%, more preferably from about 0.1% to about 5% by weight of composition.
Suitable cationic polymers include Polyquaternium-4 (Celquat H-100; L200—supplier National Starch); Polyquaternium-11 (Gafquat 734; 755N—supplier ISP); Polyquaternium-16 (Luviquat FC370; FC550; FC905; HM-552 supplier by BASF); PVP/Dimethylaminoethyl methacrylate (Copolymer 845; 937; 958—ISP supplier); Vinyl Caprolactam/PVP/Dimethylaminoethyl Methacrylate copolymer (Gaffix VC-713; H2 OLD EP-1—supplier ISP); Chitosan (Kytamer L; Kytamer PC—supplier Amerchol); Polyquaternium-18 (Mirapol AZ-1 supplied by Rhone-Poulenc); Polyquaternium-24 (Quatrisoft Polymer LM-200—supplier Amerchol); Polyquaternium-28 (Gafquat HS-100 —supplier ISP) Polyquaternium-46 (Luviquat Hold—supplier BASF); and Chitosan Glycolate (Hadagen CMF; CMFP—supplier Henkel).
Preferred cationic polymers are Polyquaternium-4; Polyqu
