B~CXGROllND OF TIIE INVENTION
The present invention relates to cosmetic compositions comprising select conjugated dienes, which, when topically applied to animal, including human, skin provide protection from the chronic effects of prolonged exposure to sunlight.
A variety of physiological responses to ultraviolet radiation have been observed, and various methods of con-trolling the harmful responses have been provided. The most well recogniæed responses include, for example, immediate responses such as the generation of erythema (sunburn) followed by reversible pigmentation or melanization, and chronic responses such as wrinkling, creasing, and carcinoma of the skin. In general, it is believed that both immediate and chronic responses occur as a consequence of varying ~- degrees of exposure to ultraviolet radiation in the range of 2950A to 4000 A. Within this range, ultraviolet radiation is able to penetrate the outer protective layers of the skin.

One means of controlling undesirable responses to ultraviolet radiation is to avoid exposure to sunlight for more than short periods of time. However, most people enjoy outdoor recreation and admire melanization of the skin. Moreover, some degree of insolation is desLrable to insure adequate Vitamin D synthesis. Accordingly, previous research has focused on methods of control?ing the more immediate erythemogenic responses, thus enabling people to enjoy exposure without undue discomfort or irritation. Commercially available "suntanning" prepara-tions mitigate the dosage of erythemogenic radiation ; which penetrates the outer skin thereby allowing the . ~
tanning response while preventing severe erythema. A
wide variety of ultraviolet reflecting and absorbing is agents are known and disclosed in the prior art~
Although suntanning preparations enable people ~, to enjoy outdoor activities without discomfort, such prep-arations also mute the natural warning system which calls . ': .
- attention to the prospect o~ c~ronic damage. As a -consequence of the prolonged periods of exposure, encouraged by reduced erythemogenic response, absorbed ultraviolet radiation is believed to cause chronic changes in the epidermis. Hyperkeratinization, which constitutes the major natural defense to prolonged exposure, increased marking of the skin; areas of pigmentation and atrophy;
superficial scaling and telangiectasls or tumorous swelling ~ ~ .

of the small blood vessels constitute some of the visible. ~
signs of chronic damage. The development of skin cancer or ~ ~.
pre-cancerous lesions (actinic keratoses) is also known to be induced by extensive exposure to erythemogenic radiation.
Accordingly, while known compositions comprising sunscreening and ultraviole~ radiation absorbing agents provide relief from the more immediate erythemogenic response, . the chronic effects of prolonged exposure to sunlight remain ~.
substantially unaffected.

The present invention provides cosmetic compositions .~ which, when topically applied, provide substantially complete .
relief from the chronic effects of exposure to sunlight, comprising a select con~ugated diene in combination with a .
. ~
topical pharmaceutically acceptable surfactant containing vehicle. Thus, the present invention in its broadest aspect relates to a composition adapted for topical application and :
. capable of inhibiting chronic damage to skin induced by ultra-violet radiation in the range of 2,950 A to 4000 A, comprising an effective ultraviolet absorbing amount from about 0.001%

DESCRIPTION OF THE PREFERRED EMBODIMENTS
,, I :
The essence of the instant invention resides in the discovery that certain con~ugated dienes, more thoroughly described hereinafter, when topically applied prevent the undesirable chronic effects of prolonged exposure to sunlight.
Cosmetic compositions comprising these conjugated dienes 30 can be topically applied :~
`' - - 3b -:: ~
: ~ -.. ...

1~71~2~4 to prevent chronic damage to the skin without inhibiting the desirable responses to insolation.
; The select conjugated dienes suitable for use in the compositions of this invention are those capable of quenching the excited-states of biogenic chromophores con-tained in aromatic amino and nucleic acids. Although not , wishing to be bound by theory, it is believed that undesirable `~ ~ell change resulting ~rom exposuxe to sunlight can be --. . - .
controlled by inhibiting one or more of the usual photo-chemical reactions that affect DNA and RNA syntheses.
One of the known ,photochemical reactions that in~luences ,~ `
DNA and RNA syntheses is the photodimerization of ; pyrimidine bases, thymine and cytosine in the case of DNA, i,,,,, and uracil and cytosine in the case of RNA. Photodimeriza-tion reactions can be broadly described as the photocyclo-addition of a ground-state molecule with an excited-state ,, .
` molecule. Certain conjugated diene~ are known excited- ~ ~
.~, st~te quenchers, see, for example, Lamola, Pure AP~1. Chem.
3~, No. 2, (1973), "Photochemistry and Structure in Nucleic Acids". Thus, it has been fowld that by utilizing , conjugated dienes to quench the excited-state of the , biogenic chromophores, it is possible to inhibit photo-~, dimerization of the bases and consequently control . . . undesirable cellular change, i.e., chronic damage.
The class o~ conjugated dienes capable of quenching the excited-state of biologic chromophores can be generically described by the following formulae:

: It has been found that suitable conjugated dienes can be structurally tailored to provide not only protection from chronic damage but also protection from more immediate erythemo-genic responses by incorporating a sunscreening or ultraviolet radiation absorbing moiety into the basic diene structure.
Thus, t~e present invention encompasses compositions for topical protectLon from both erythema and chronic damage.
Especially preferred conjugated dienes structurally tailored to provide, as`an additional benefit, protection from erythemogenic responses include, for example, esters and amides prepared by reaction of conjugated dieneols and amines, such as those enumexated above, with the acid of an ultraviolet radia-.
tion screening or absorbing compoundO Specific acids suitable for use in preparing tailored conjugated dienes include, for example, p-methoxy cinnamic acid, p~aminobenzoic acid, salicylic acid, p-dimethyl amino benzoic acid, and uraconic acid.
The composltions of the present invention comprise from about 0.001% to about 25%, preferably 0.01% to 15%, by weight, of a con~ugated diene. It has been found that below about 0.001%, by weight, the conjugated dienes do not provide significant protection from the chronic damage o~ prolonged exposure to ultraviolet radiation; and that concentrations above about 25%~ by weight, do not significantly enhance th~
efficacity of the compositions of this invention.
As noted, the present invention encompasses composi-tions for topically controlling chronlc skin damage '' ~, ~[)70Z~

comprising a conjugated diene, a~ described above, and a surfactant-containing vehicle. It has been found that the surface active agent provides a more ef~icient absorp-tion and retention by the skin of the active ingredient of the compositions of this invention. Various vehicles have been employed to carry the active, and the make-up of the vehicle profoundly affects the efficacy o~ the product.
Suitable vehicles, once spread on the skin, should remain in place as a continuous film, closely adhering to or penetrating the skin surface, and should resist washing off either by perspiration or by immersion in fresh or salt water. The characteristics cf a suitable vehicle vary greatly aepending es~entially upon the ideas and .
prejudices of the formulator. Creams, cream lotions, oils, 15 gels, hydroalcoholic lotions, jellies, lipsticks and aerosol foams and sprays are common formulations. In any event, suitable vehicles contain from about 0.1% to about 10%
of a nonionic, cationic, or amphoteric sur~ace active agent; the preferred amount is in the range of about 0.1%
to about 2%. The upper limit of such surface active agent (surfactant) is critical where large amounts may result in excessive foaming. Cationic, and particularly nonionic, surface active agents are desirable although anionic non-soap surfactants are also suitable. Anionic non-soap sur-factants are preferably used at concentrations of about 0.01% to about 0.5% and desirably below about 0.1%.
l Water-soluble nonionic surfactants are highly suitable - for use in this invention; they include detergent co~pounds , produced by the condensation of alkylene oxide groups ~l 30 (hydrophilic in nature) with an organic hydrophobic -i compound which may be aliphatic or alkyl aromatic in ,~

The preferred nonionic surfactant is available on the market under the trademark of "Pluronic". These compounds are formed by condensing ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with ~ropylene glycol. The hydrophobic portion of the molecule exhibits water insolubility. Its molecular weight is of the order of lS00 to 1800. The addition of polyoxyethylene radicals to this hydrophobic portion tends to increase the water solubility of the molecule as a whole. Liquid products are obtained up to the point where the polyethylene content is about 50% of the total weight of the condensation product.
Further increase in the relative content of polyoxyethylene to hydrophobic portion renders the final product wax-like ~ -or solid in consistency. The molecular weights of Pluronic L-61, L-64 and F-68 which find particular utility in the practice of the present invention are about 2000, 3000 and 8000 respectively.
Examples of cationic surfactants suitable for practice ~i of this invention are the detergent quaternary ammonium salts.

In addition to a surfactant, the vehicle used herein may contain solid or liquid diluents, penetrants, thickeners, stabilizers, preservatives, and the like or mixtures thereof.
Diluents which are suitable for use herein include, for example, water, ethanol, glycerin, and saline. Particularly useful diluents are hydrophilic, water-soluble or miscible diluents, which term, for the sake of convenience, is intended to include water itself. Hydrophilic diluents generally lower the freezing point of the diene component so that the - compositions are useful at temperatures encountered during cold weather use and storage.
Penetrants which are suitable fox use herein include, for example, the dialkyl sulfoxides, and the polyoxyethylene sorbitan higher atty acid monoesters. U.S. Patent 3,740,420 granted July 1~, 1973, describes in detail pharmaceutical penetration and the use of dialkyl sulfoxides as penetrants.
For various applications, the compositions herein may be formulated into convenient form for appli-cation with thic~ening agents. Such forms include thickened solutions or lotions, ointments, creams, gels, and the like.
These forms are advantageously employed to lessen the run-off , from the skin that may occur ~ith the most fluid composition ~ '' ' , .

It is advantageous to use water dispersihle thickening agents (i.e., agents dispersible in water to form a homo-geneous distribution or solution), such as the polyethylene glycols, as they are readily compatible with water or other diluents and may be readily washed from the skin. Alter-10 natively, an emulsion base may be employed to Lmpart the ~ ;~
desired thickening effect, a better spreading and wetting effect, and a retardation of the skin-drying effect of certain penetrants.
The water-soluble thickening bases utilize, for example, a variety of polyethylene glycols having differing viscosities, depending upon the desired consistency; water-:, .
dispersible gums; carboxy vinyl polymers, methyl cellulose, alginates, and the like. The compositions incorporating ~
;~emulsion bases may contain the usual adjuvants such as a ;
`20 fatty alcohol, an emulsifier, and water. ~`
The required application of conjugated diene will vary with the particular circumstances of application, the ; duration of anticipated exposure, and effectiveness of the . ,:
