The reaction is carried out in the presence of an acid, with or without the addition of one or more solvents at a reaction temperature of from 0 to 200°C.

Generally from 0.8 to 2.0 mol of the compound of formula (1 b) and from 0.8 to 2.0 mol of a compound of formula (1 c) are used per free amino group of compound (1 a).

The reaction is preferably carried out in DMSO, N-methylpyrrolidone, DMF or DMA. It is also possible, however, to use protic solvents, such as ethanol, methanol, isobutanol or iso- propanol. The reaction can also be carried out in an aliphatic or aromatic solvent, such as hexane, toluene or xylene. It is also possible to use ethers, such as diethyl ether and tetrahy- drofuran, or halogenated solvents, such as chloroform or dichloromethane.

The reaction is preferably carried out as a one-pot reaction. The individual reactants may, however, be added in any desired order. For example, the catalyst may be present from the beginning or may be introduced only later. It is also possible first to start the reaction be- tween (1 b) and (1 c) in the presence of the catalyst and only later to add the triazine com- pound of formula (1 a). It is equally possible first to react the compound of formula (1 a) with the compound of formula (1 b) in the presence of a catalyst and to add (1 c) later.

The reaction can be carried out at a temperature of from 0 to 200°C, preferably at from 20 to 100°C and especially from 50 to 80°C.

The reaction times are dependent upon the reaction temperature. Within the preferred tem- perature range, the reactions are generally completed within from 1 to 6 hours. At low tem- peratures, the reaction time increases considerably and may be 48 hours or more.

As catalysts there are used organic and inorganic Brönstedt or Lewis acids or mixtures thereof. Examples of typical acids are phosphoric acid, trifluoroacetic acid, oxalic acid, methanesulfonic acid, toluenesulfonic acid, phenylsulfonic acid and trifluoromethanesulfonic acid.

Preference is given, however, to the use of Lewis acids, such as phosphorus oxychloride, copper chlorides, zinc chloride, lanthanum chloride, chromium chlorides, iron chlorides, aluminium chloride, titanium chlorides, ger- manium chloride, and hydrates thereof. It is also possible to use acidic ion exchangers.

The product is isolated according to conventional techniques, such as filtration, centrifuga- tion, phase separation and liquid extraction. The products are purified, inter alia, by recrys- tallisation from a solvent or from a solvent mixture, preference being given to solvents or solvent mixtures containing alcohols. Purification can also be carried out by chroma- tographic methods and by distillation.

It will be understood in that connection that, in addition to the UV absorbers according to the invention, it is also possible for more than one of the additional light-protective agents to be used, for example, two, three, four, five or six further light- protective agents.

Preference is given to the use of mixing ratios of UV absorbers according to the inven- tion/further light-protective agents of from 1: 99 to 99: 1, especially from 1: 95 to 95: 1 and preferably from 10: 90 to 90: 10, based on weight. Of special interest are mixing ratios of from 20: 80 to 80: 20, especially from 40: 60 to 60: 40 and preferably of approximately 50: 50.

Such mixtures can be used, inter alia, to improve solubility or increase UV absorption.

Appropriate mixtures can be used especially advantageously in the cosmetic preparations described below.

The cosmetic preparations are suitable especially as UV filters, that is to say for the protec- tion of organic materials that are sensitive to ultraviolet light, especially skin and hair, against the damaging effect of UV radiation.

The UV absorbers can be used either in the dissolved state or in the micronised state.

Any known process suitable for the preparation of microparticles can be used for the prepa- ration of the micronised UV absorbers, for example: - wet-grinding with a hard grinding medium, for example zirconium silicate and a protective surfactant or a protective polymer in water or in a suitable organic solvent; - spray-drying from a suitable solvent, for example aqueous suspensions or suspensions containing organic solvents, or true solutions in water, ethanol, dichloroethane, toluene, N-methylpyrrolidone inter alia ; - by the expansion according to the RESS process (Rapid Expansion of Supercritical Solu- tions) of supercritical fluids (e. g. CO2) in which the UV filter or filters is/are dissolved or the expansion of fluid carbon dioxide together with a solution of one or more UV filters in a suitable organic solvent; - by reprecipitation from suitable solvents, including supercritical fluids (GASR process = Gas Anti-Solvent Recrystallisation/PCA process = Precipitation with Compressed Anisol- vents).

As grinding apparatus for the preparation of the micronised organic UV absorbers there may be used, for example, a jet mill, ball mill, vibratory mill or hammer mill, preferably a high- speed mixing mill. The grinding is preferably carried out with a grinding aid, for example an alkylated vinylpyrrolidone polymer, a vinylpyrrolidone/vinyl acetate copolymer, an acyl glu- tamate, an alkyl polyglucoside, ceteareth-25 or a phospholipid.

The micronised UV absorbers so obtained usually have an average particle size that is from 0.02 to 2, preferably from 0.05 to 1.5, and more especially from 0.1 to 1.0, nm.

The UV absorbers can also be used dry in powder form. For that purpose the UV absorbers are subjected to known grinding methods, such as vacuum atomization, countercurrent spray-drying etc.. Such powders have a particle size of from 0.1 nm to 2, um. To avoid the occurrence of agglomeration, the UV absorbers can be coated with a surface-active com- pound prior to the pulverisation process, for example with an anionic, non-ionic or ampho- teric surfactant, e. g. a phospholipid or a known polymer, such as PVP, an acrylate etc..

The cosmetic preparations contain, for example, from 0.1 to 30 % by weight, preferably from 0.1 to 15 % by weight and especially from 0.5 to 10 % by weight, based on the total weight of the composition, of one or more UV absorbers and at least one cosmetically toler- able adjuvant.

The cosmetic preparations can be prepared by physically mixing the UV absorber (s) with the adjuvant using customary methods, for example by simply stirring together the individual components, especially by making use of the dissolution properties of already known cos- metic UV absorbers, for example OMC, salicylic acid isooctyl ester, inter alia. The UV ab- sorber can be used, for example, without further treatment, or in the micronised state, or in the form of a powder.

The cosmetic preparations may be, for example, creams, gels, lotions, alcoholic and aque- ous/alcoholic solutions, emulsions, wax/fat compositions, stick preparations, powders or ointments.

As water-and oil-containing emulsions (e. g. W/O, O/W, O/W/O and W/O/W emulsions or microemulsions) the preparations contain, for example, from 0.1 to 30 % by weight, preferably from 0.1 to 15 % by weight and especially from 0.5 to 10 % by weight, based on the total weight of the composition, of one or more UV ab- sorbers, from 1 to 60 % by weight, especially from 5 to 50 % by weight and preferably from 10 to 35 % by weight, based on the total weight of the composition, of at least one oil compo- nent, from 0 to 30 % by weight, especially from 1 to 30 % by weight und preferably from 4 to 20 % by weight, based on the total weight of the composition, of at least one emulsifier, from 10 to 90 % by weight, especially from 30 to 90 % by weight, based on the total weight of the composition, of water, and from 0 to 88.9 % by weight, especially from 1 to 50 % by weight, of further cosmetically tolerable adjuvants.

The addition products of ethylene oxide and/or of propylene oxide with fatty alcohols, fatty acids, alkylphenols, glycerol mono-and di-esters and also sorbitan mono-and di-esters of fatty acids, or with castor oil, are known, commercially available products. They are usually homologue mixtures, the average degree of alkoxylation of which corresponds to the ratio of the amounts of ethylene oxide and/or propylene oxide and substrate with which the ad- dition reaction is carried out. C12-C, 8 fatty acid mono-and di-esters of addition products of ethylene oxide with glycerol are known, for example, from DE-A-2 024 051 as fat-restoring substances for cosmetic preparations.

C8-Cl3Alkyl-mono-and-oligo-glycosides, their preparation and their use are known from the prior art. They are prepared especially by reacting glucose or oligosaccharides with primary alcohols having from 8 to 18 carbon atoms. Suitable glycoside radicals include mono- glycosides in which a cyclic sugar radical is glycosidically bonded to the fatty alcohol and also oligomeric glycosides having a degree of oligomerisation of up to preferably about 8.

The degree of oligomerisation is a statistical average value based on a homologue distribu- tion customary for such technical-grade products.

It is also possible to use zwitterionic surfactants as emulsifiers. The term"zwitterionic surfac- tants"denotes especially surface-active compounds that carry at least one quaternary am- monium group and at least one carboxylate and/or sulfonate group in the molecule. Zwit- terionic surfactants that are especially suitable are the so-called betaines, such as N-alkyl- N, N-dimethylammonium glycinates, for example cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N, N-dimethylammonium glycinates, for example cocoacylaminopropyl- dimethylammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines each having from 8 to 18 carbon atoms in the alkyl or acyl group and also cocoacylamino- ethylhydroxyethylcarboxymethylglycinate. Special preference is given to the fatty acid am- ide derivative known by the CTFA name cocamidopropyl betaine. Likewise suitable as emul- sifiers are ampholytic surfactants. Ampholytic surfactants are to be understood as meaning especially those which, in addition to containing a C8-C, 8-alkyl or-acyl group, contain at least one free amino group and at least one-COOH or-SO3H group in the molecule and are capable of forming internal salts. Examples of suitable ampholytic surfactants include N- alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic ac- ids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids, each having approximately from 8 to 18 carbon atoms in the alkyl group. Ampholytic surfactants to which special preference is given are N-cocoalkylaminopropionate, cocoacylaminoethylaminopropionate and C12-C, 8- acylsarcosine. In addition to the ampholytic emulsifiers there also come into consideration quaternary emulsifiers, special preference being given to those of the esterquat type, pref- erably methyl-quaternised di-fatty acid triethanolamine ester salts.

Non-ionic emulsifiers are preferred. Of the non-ionic emulsifiers mentioned, special prefer- ence is given to ethoxylated fatty alcohols having from 8 to 22 carbon atoms and from 4 to 30 EO units.

The emulsifiers may be used in an amount of, for example, from 1 to 30 % by weight, espe- cially from 4 to 20 % by weight and preferably from 5 to 10 % by weight, based on the to- tal weight of the composition. It is, however, also possible in principle to dispense with the use of emulsifiers.

Also suitable are simethicones, which are mixtures of dimethicones having an average chain length of from 200 to 300 dimethylsiloxane units with hydrogenated silicates. A detailed survey by Todd et al. of suitable volatile silicones may in addition be found in Cosm. Toil. 91,27 (1976).

Typical examples of fats are glycerides, and as waxes there come into consideration, inter alia, beeswax, carnauba wax, candelilla wax, montan wax, paraffin wax, hydrogenated cas- tor oils and fatty acid esters or microwaxes solid at room temperature optionally in combina- tion with hydrophilic waxes, e. g. cetylstearyl alcohol or partial glycerides.

Under the trade mark Locron of Hoechst AG, Frankfurt (FRG), there is available commercially, for example, an aluminium chlorohydrate corresponding to formula Al, (OH), Cl x 2.5 H, O, the use of which is especially preferred (see J. Pharm. Pharmacol. 26, 531 (1975) ). Besides the chlorohydrates, it is also possible to use aluminium hydroxy- acetates and acidic aluminium/zirconium salts. Esterase inhibitors may be added as further deodorising active ingredients. Such inhibitors are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and especially triethyl citrate (HydagenS CAT, Henkel KGaA, Düsseldorf/FRG), which inhibit enzyme activity and hence reduce odour formation.

Natural aromatic substances are, for example, extracts from blossom (lilies, laven- der, roses, jasmine, neroli, ylang-ylang), from stems and leaves (geranium, patchouli, petit- grain), from fruit (aniseed, coriander, caraway, juniper), from fruit peel (bergamot, lemons, oranges), from roots (mace, angelica, celery, cardamom, costus, iris, calmus), from wood (pinewood, sandalwood, guaiacum wood, cedarwood, rosewood), from herbs and grasses (tarragon, lemon grass, sage, thyme), from needles and twigs (spruce, pine, Scots pine, mountain pine), from resins and balsams (galbanum, elemi, benzoin, myrrh, olibanum, opoponax). Animal raw materials also come into consideration, for example civet and cas- toreum. Typical synthetic aromatic substances are, for example, products of the ester, ether, aldehyde, ketone, alcohol or hydrocarbon type.

It is preferable, however, to use mixtures of various aromatic substances that together produce an attractive scent. Ethereal oils of relatively low volatility, which are chiefly used as aroma components, are also suitable as perfume oils, e. g. sage oil, camomile oil, clove oil, melissa oil, oil of cinnamon leaves, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, gal- banum oil, labolanum oil and lavandin oil.

The colourants are usually used in concentrations of from 0.001 to 0.1 % by weight, based on the total mixture.

Typical examples of bacteria-inhibiting agents are preservatives that have a specific action against gram-positive bacteria, such as 2,4, 4'-trichloro-2'-hydroxydiphenyl ether, chlor- hexidine (1,6-di (4-chlorophenyl-biguanido) hexane) or TCC (3,4, 4'-trichlorocarbanilide).

A large number of aromatic substances and ethereal oils also have antimicrobial properties.

Typical examples are the active ingredients eugenol, menthol and thymol in clove oil, mint oil and thyme oil. A natural deodorising agent of interest is the terpene alcohol farnesol (3,7, 11-trimethyl-2, 6, 1 0-dodecatrien-1-ol), which is present in lime blossom oil. Glycerol monolaurate has also proved to be a bacteriostatic agent. The amount of the additional bac- teria-inhibiting agents present is usually from 0.1 to 2 % by weight, based on the solids con- tent of the preparations.
