Description

~0 95/04517 2 1 6 8 ~ ~ 2 PCTIUS94/08615 COSMETIC COMPOSITIONS

Field of the Invention The present invention relates to cosmetic compositions and more particularly, to pigmented foundation make-up compositions and concealers having anti-acne activity and formulation and colour stability.

Back~round of the Invention A foundation composition can be applied to the face and other parts of the body to even skin tone and texture and to hide pores, illlpelrections, fine lines and the like. A foundation composition is also applied to moisturize the skin, to b~l~nGe the oil level of the skin and to provide protection ~g~inst the adverse effects of sunlight, wind and the harsh environment.

Make-up compositions are generally available in the form of liquid or cream suspensions, emulsions, gels, pressed powders or anhydrous oil and wax compositions.

US Patent No. 3,444,291 discloses a method of filling and camo~lfl~ing skin cavities by applying a composition which includes 65 to 75 parts by weight of a microcrystalline wax and about 25 to 35 parts of a mineral oil. The composition includes a colourant, preferably a coal tar dye, for example, D &C Red No. 17, which matches the colour of the user's skin.

A spreadable, flowable and greaseless cosmetic cover-up composition is taught in US Patent No 4,486,405. That composition is characterized by wo 95/04517 216 8 8 ~ 2 PCT/US94/0861 the presence of a first and a second alkoxylated surfactant present in substantially the same concentration.

US Patent No. 4,804,532 recites a facial cosmetic powder which utilizes crystalline silica in much lower concentration than that employed in the then prior art compositions. This powder, used as a blush or a facial coating, is said to be effective in hiding skin wrinkles, lines and pores.
The composition is a mixture of a colour phase and a diluent phase. The colour phase is formed by blending crystalline silica with colourants. The resultant colour phase is mixed with the diluent phase, essentially formed from nacreous materials such as talc and mica, to form the composition.

The use of a foundation composition which has a significantly high concentration of nacreous material is taught in US Patent No. 3,978,207.
This foundation, a pressed powder composition, is characterized by the presence of a nacreous material such as mica and a binder oil which provides a frosted pearl effect, that is, a lustrous look. The colour of this foundation is provided by the nacreous material.

US Patent No. 4,659,562 discloses a cosmetic make-up composition which includes, as a binding agent therefore, an intim~te mixture of from 5 to 95 weight percent of a mixture of finely divided silica and about 5 to 95 weight percent of finely divided polyethylene fibres. The composition is recited to m~int~in its uniformity over the areas of the skin to which it is applied. That is, it is said to be "creaseproof". The composition of the '562 patent includes colourant in admixture with nacreous agents.

N~k~mllra et al., Preprints of the XIVth I.P.S.C.C. Congress, Barcelona, 1986, Vol. I, 51-63 (1986) describes a novel make-up composition utili~ing spherical silica and poly~imethyl siloxane. This combination is recited to provide a foundation which reduces wrinkle visibility to a greater extent than make-up foundations with which it was compared.
This reduction in wrinkle visibility is c~lsed by optical blurring enhanced by the novel use of spherical silica and polydimethyl siloxane.

US Patent No. 5,143,722 discloses a cosmetic make-up composition comprising water-in-oil emulsions comprising pigment coated with polysiloxane, a silcone phase, a water phase and a polydiorganosiloxane-polyoxyalkylene copolymeric surfactant.

Foundations in the form of water-in-oil emulsions are well known and provide good coverage and good skin feel, wear and appearance. At the sarne time, it would be desirable to provide a foundation composition having topical anti-acne activity. There are many compounds which are known to exhibit anti-acne properties when applie!d topically to the skin. A cor"l"only used keratolytic agent having anti-acne activity is salicylic acid. As salicylic acid is virtually insoluble in water it is diffficult to incorporate into the aqueous phase of an emulsion composition. Delivery of salicylic acid from the pigment-containing oil phase of an emulsion foundation composition can, however, lead to discoluration of the co",posilion due to interaction between the salicylic acid and pigments, especially of the iron oxide type. It woulcl therefore be desirable to deliver the salicylic acid in soluble form from the aqueous phase.

Polyvinylpyrrolidone is known for use as a solubilizing/col"~'-.xing agent in a variety of compositions.

GB-A-2,041,963 dis~,loses an aqueous detergent composition for cleansing oily skin con,pri~i"g a water-soluble salt of an N-acyl ester of sarcosine, a polyvinylpyrrolidone cosolubilizer and a protein and/or protein hydrolysate. The con,position can also contain salicylic acid as a keratolytic agent and a buffer such as citric acid/citrate. There is no disclosure, however, of cos",etic compositions containing solubilized acidic anti-acne actives in fully protonated form as specified herein.

Since acidic anti-acne agents are most active at low pH (when a high concentration of free acid is present in solution) it would be desirable to deliver the agent from an aqueous phase at a pH at which it exists significantly in p,otondlc3d form. It is accordingly a primary aspect of this invention to provide a cosmetic composition c,or"~risi"g a low pH aqueous solution of an anti-acne active.

It is also an aspect of the invention to provide a cosmetic composition having improved anti-acne activity and stability.

It is a further aspect of the invention to provide a cos~"etic composition in the form of an oil-in-water or water-in-oil emulsion having improved colour stability and pigmenVanti-acne active co" ,p~"~ 'ity.

SummarV of the Invention In accordance with one aspect of the present invention, there is provided a cosmetic composition in the form of an emulsion, gel or lotion comprising an aqueous/alcoholic solution of an acidic anti-acne active and a pyrrolidone-based comFI~ xirlg agent therefor, and wherein theaqueous/alcoholic solution has a pH of less than about PKa + 1, where PKa is the logarithmic acidity constant for the fully protonated anti-acne active.

The cosmetic compositions of the present invention provide anti-acne efficacy together with improved product and colour stability.

According to another aspect of the present invention there is provided a make-up composition in the form of a water-in-oil or oil-in-water emulsion cornprising an acidic anti-acne active dissolved in the aqueous phase and a pigment or mixture of pi~menl~ dispersed in the oil phase.

All levels and ratios are by weight of total con,position, unless otherwise indicated. Chain length and degrees of alkoxylation are also specified on a weight average basis.

Detailed DescriPtion of the Invention The cosmetic COI I ~posilion according to one aspect of the present invention comprises an aqueouc/alcoholic solution of an acidic anti-acne active and a pyrrolidone-based complexing agent. The col"posilion is in the form of an emulsion, gel or lotion.

-~ 95/04S17 88~,~ PCT/US94/08615 According to this first aspect of the present invention a first essential component is an aqueous/alcoholic solution of an anti-acne active.
Suitable anti-acne actives for use herein include salicylic acid, retinoic acid and its derivatives, azelaic acid and its derivatives, lactic acid, glycolic acid, pyruvic acid, flavonoids, and mixtures thereof.

The anti-acne active used in the composition herein is preferably selected from salicylic acid and azelaic acid, and mixtures thereof, more preferably salicyclic acid. The anti-acne active is present at a level of from about 0.1% to about 10%, preferably from about 0.1% to about 5%, more preferably from about 0.5 % to about 3 %, by weight of composition.

The anti-acne active is solubilized in water or an alcoholic solution, for example, solutions based upon C2-C6 alcohols, diols and polyols, preferred alcohols being selected from ethanol, dipropylene glycol, butylene glycol, hexylene glycol, and mixtures thereof. Alcohol is preferably present in the compositions herein at a level of from about 1%
to about 20%. The final aqueous/alcoholic anti-acne active solution preferably has a pH at ambient temperature (25~C) of less than about pKa + 1, where pKa is the logarithmic acidity constant for the fully protonated anti-acne active. In preferred embodiments, the pH of the final solution is less than about pKa~

The logarithmic acidity constant is thus defined by reference to the equilibrium H+ + Hn-lA = HnA

where HnA is the fully protonated acid, n is the number of protons in the fully protonated acid and Hn 1 A is the conjugate base of the acid corresponding to loss of one proton.

wo 95/04517 ?,~6~ PCT/US94/0861'-The acidity constant for this equilibrium is therefore Kn = [HnA]
[H+] [Hn-1A]
and pKa = logloKn For the purposes of this specification, acidity con~t~nts are defined- at 25~C and at zero ionic strength. Literature values are taken where possible (see Stability Constants of Metal-Ion Complexes, Special Publication No. 25, The Chemical Society, London); where doubt arises they are determined by potentiometric titration using a glass electrode.

The pKa of the acidic anti-acne active used herein is preferably in the range of from about 1 to about 6, more preferably from about 1 to about 4.5, especially from about 1.5 to about 4Ø

The pH of the final aqueous/alcoholic anti-acne active solution is preferably in the range of from about 1 to about 7, more preferably from about 2 to about 5, especially from about 2 to about 4. At pH values of less than about 5 the aqueous phase is preferably free of acid labile species such as acrylic acid/ethyl acrylate copolymers and polyglycerylmethacrylate .

A second essential component of the compositions of the first aspect of the present invention is a pyrrolidone-based complexing agent.

The pyrrolidone-based complexing agent is useful herein from the viewpoint of aiding solubilization of the anti-acne active. The pyrrolidone-based complexing agent used herein is preferably selected from polyvinylpyrrolidone complexing agents or C1-C4 alkyl polyvinylpyrrolidone complexing agents having a molecular weight (viscosity average) in the range from about 1500 to about 1,500,000, preferably from about 3000 to about 700,000, more preferably from about 5000 to about 100,000. Suitable examples of pyrrolidone-based complexing agents are polyvinylpyrrolidone (PVP) (or povidone) and ~6g ~o 95/04517 ( ~ ~ ~ PCT/US94/08615 butylated polyvinylpyrrolidone. The most preferred pyrrolidone-based complexing agent herein is a polyvinylpyrrolidone complexing agent.
PVP is commercially available under the trade name Luviskol (RTM) from BASF. A preferred PVP complexing agent herein is Luviskol K17 which has a viscosity-average molecular weight of about 9,000. Other pyrrolidone-based complexing agents for use herein include C1-C1g alkyl or hydroxyalkyl pyrrolidones such as lauryl pyrrolidone.

The pyrrolidone-based complexing agent is present in the composition herein in a level of from about 0.1% to about 10%, preferably from about 0.1 % to about 5 % by weight of composition. The weight ratio of anti-acne active: pyrrolidone-based complexing agent is in the range from about 10:1 to about 1:10, preferably from about 5:1 to about 1:5.

Preferred embodiments of the invention additionally comprise from about 0.01% to about 5% by weight of an acid or salt thereof which is soluble in water at pH values of less than or equal to the pKa of the corresponding acid, for example, an acid selected from citric acid, boric acid, and salts, and mixtures thereof. These materials are valuable herein in combination with the pyrrolidone-based complexing agent from the viewpoint of aiding solubilization of the anti-acne active. Particularly preferred herein from this viewpoint is a sodium salt of citric acid. In ~refelled embo~liments~ the acid or salt thereof is soluble to a level of at least 5% w/w at 25~C.

The composition of the present invention can be in emulsion (w/o or o/w), gel or lotion form but is preferably in the form of a water-in-oil emulsion, wherein in prefer~ed embo~liment~ the oil phase comprises a mixture of volatile silicones and non-volatile silicones. The silicone oil is present in an amount of from about 1% to about 50% by weight. Suitable volatile silicone oils include cyclic and linear volatile polyorganosiloxanes (as used herein, "volatile" refers to those materials which have a measurable vapour pressure at ambient conditions).

A description of various volatile silicones is found in Todd, et al..
