1 1 Claims, N0 Drawings DETERGENT COMPOSITIONS CONTAINING THE ETHERS AND ESTERS OF TETRAHYDROFURAN AND TETRAHYDROPYRAN This application is a continuation-in-part of my copending U.S. application, Ser. No. 763,374, filed Sept. 27, 1968 now abandoned.
In the manufacture of cleansing compositions containing detergents, it has been found necessary to incorporate materials having pleasant fragrances in order to mask undesirable odors in the detergent compositions so as to increase con- 1 sumer acceptance of the products. The well-known fragrant materials of the ester class, such as benzyl acetate and benzyl propionate, are examples of such additives. However, since most detergent formulations contain alkali, perfumery materials, such as the aforementioned esters, are decomposed by hydrolysis either during storage or during use in aqueous solutrons.
A further problem which has arisen in the use of perfumery materials and cleansing compositions concerns the presence of bleaching ingredients. The latter materials tend to oxidize perfumery additives and it has been found that the perfumes are decomposed upon storage in the presence of many bleaching ingredients.
It is an object of this invention to provide detergent compositions having desirable fragrances and are not discolored.
A further object is the production of detergent compositions with desirable odor characteristics which retain their fragrances in the presence of bleaching ingredients and which are stable in alkaline media.
The perfumery compounds used in the detergent compositions of the invention are the ethers and esters of tctrahydrofuran and tetrahydropyran having the structural formula C; to 0 alkyl (propyl, butyl, amyl, hexyl heptyl, octyl,
nonyl, decyl, undecyl) 45 The amyl tetrahydropyranyl ether has a lavender odor, the isoamyl tetrahydropyranyl ether has a soft lavender odor, the hexyl tetrahydropyranyl ether has a witch hazel character and the decyl tetrahydropyranyl has a clean, soapy odor. The odors of the remaining twelve non-alkyl tetrahydropyran compounds given above are respectively green, rose-slightly sharp; flowery, slightly sharp green; green, floral as apple blossom; green, linden-like, strong; green rosy, more leafy than geraniol; fragrant, lily-linden, fresh; violet leaf green, similar to methyl heptyne carbonate; strong bitter earthy, slight green galbanum type; animal-civette like, strong; fresh, etheral, earthy, strong; high-pitched, waxy violet; and clean, rosy green, spicy.
The tetrahydrofuran compounds have nearly the same odor as the tetrahydropyran compounds described above except for the following: n-hexyloxytetrahydrofuran has a natural green odor; n-heptyloxytetrahydrofuran has a fresh green jasmin odor; n-octyloxytetrahydrofuran has an intense citrus note; 2- pentyloxymethyltetrahydrofuran has a sweet, floral odor; 2- decyloxytetrahydrofuran has a clean, citrus-like odor; the 2- nonyloxytetrahydrofuran has a rosy odor; and the tetrahydrofuranyl ether of Formula 7 has a Bois de rose odor.
The tetrahydropyran and tetrahydrofuran ethers or esters may be prepared in the conventional or classical manner by reacting dihydropyran or dihydrofuran with the appropriate alcohol or carboxylic acid corresponding to the R radical above. Thus the appropriate alcohol for the compound of Formula II is phenylethanol while the appropriate alcohol for the compound of Formula VII is linalool. For example, dihydropyran or dihydrofuran (0.6 mole) and the appropriate alcohol or carboxylic acid (0.5 mole) are stirred for one hour with a catalytic amount of p-toluene sulfonic acid. The mixture is cooled, taken up in ether, washed with sodium hydroxide solution and then with water until neutral. The ether layer is dried over anhydrous magnesium sulfate and concentrated on a steam bath (with a stream of air blowing on the mixture). The structures of the dihydropyran or dihydrofuran adducts are confirmed by NMR (nuclear magnetic resonance) analysis. More specifically, for example the compound 2-decyloxytetrahydrofuran is prepared as follows:
A mixture of 2,3-dihydrofuran, 4.2 g (0.06 mole) prepared by the method of Paule et a]. [BulL Soc. Chim. France 668 (l950)]7.9 g (0.05 mole) and a spatula full of p-toluenesulphonic acid was stirred for one hour. The reaction mixture was the cooled, taken up in ether, washed with water until neutral. The ether layer was dried over anhydrous MgSO filtered and concentrated under vacuum at 40 C until all traces of ether and excess 2,3-dihydrofuran had disappeared. The residue, 2-decyloxytetrahydrofuran, has a very clean, citrus-like odor.
To form the compounds where R, is CH O the following procedures are used:
Tetrahydropyran-2-methanol, 35 g (0.3 mole) was dissolved in 80 ml of benzene and reacted with 7 g (0.3 mole) of metallic sodium at refluxing temperature for eight hours. n- Hexyl bromide, 50 g (0.3 mole) was then added and the reaction mixture refluxed for three more hours. The reaction mixture was then filtered to remove sodium bromide, concentrated in vacuo, and the residue distilled to yield 26.1 g of the desired 2-hexyloxymethyltetrahydropyran, b.p. 144-l 46 C/33 mm., which has apowerful, green stem, ivy-like odor.
Using the procedure for preparing 2-hexyloxymethyltetrahydropyran l, 31 g (0.3 mole) of tetrahydrofurfuryl alcohol, 7 g of sodium and 45 g (0.3 mole) of n-pentyl bromide were reacted to product 19.6 g of the desired 2-pentyloxymethyl-tetrahydrofuran, b.p. l l6l 18 C/30 mm., which has a sweet, floral odor.
The detergent compositions of the invention may take any desired physical form, such as liquids, pastes, flakes, beads, powders, bars, tablets and the like. The compositions may be either heavy-duty or light-duty formulations and can be prepared in the conventional manner.
The detergent compositions contain conventional amounts, such as 5 to 99 percent by weight of an organic detergent and from about 0.01 to about 2 percent weight of the dihydropyran ether or ester. The organic detergent component can be soap, i.e., a salt of a higher fatty acid and/or a non-soap organic detergent including the anionic, cationic, nonionic, ampholytic, and zwitterionic detergent compounds. These organic detergent materials are well known and the chemical nature thereof is not a feature of the invention. Typical suitable organic detergents are set forth in Surface Active Agents" by Schwartz and Perry and Surface Active Agents and Detergents" by Schwartz, Perry and Berch, the disclosures of which are incorporated by reference herein.
The detergent compositions can contain conventional compounding materials in the usual amounts therefor, such as chlorine releasing bleaching agents, typical examples of which include chlorocyanurates, chlorinated trisodium phosphate, N-chlorosuccinimide, calcium hypochlorite, and N,N- dichloroazocarbonamidine; alkali, such as sodium hydroxide, potassium hydroxide, sodium carbonate, and the like; builders, typical examples of which are pentasodium and pentapotassium tripolyphosphate, tetrasodium and tetrapotassium pyrophosphate, trisodium nitrilotriacetate, and the like; sequesterants such as ethylene diamine tetraacetic acid and the like; soil suspending agents, for example, sodium carboxymethylcellulose and the like; fillers, representative examples of which include sodium carbonate, sodium sulfate and the like; suds boosters, such as lauric diethanolamide and the like; suds depressants, for example, long-chain monohydric alcohols; germicides, representative examples of which include 3,4,S-tribromosalicylanilide, hexachlorophene and the like; colorants; abrasives; enzymes; etc.
Although the ethers and esters of tetrahydropyran and tetrahydrofuran can be used as the sole perfumery ingredient for detergent compositions, they are more usually used, as is the custom, in a perfumery blend therefor. Representative examples of such perfume blends for detergent compositions are set forth in the following examples.

lngredients Parts by Weight Silica, 90 mesh 70 Chlorinated trisodium phosphate i0 Sodium alkylbenzene sulfonate 3.33
Sodium tripolyphosphate 16.67
Total After storage, as per Example 11, the perfume odors of these four formulations were unaffected.
Comparable Storage stability was achieved with the other tetrahydropyran and tetrahydrofuran ethers and esters given above.
All the tetrahydropyran and tetrahydrofuran ethers and esters also passed the following soap bar stability test. The perfumery material is incorporated at the 1 percent level (or the 0.5 percent level if the odor is very intense as is the case for some of the acetylenic tetra-hydropyran ethers) in an 80-20 percent tallow-coconut soap base. The perfumed soap chips are extruded and cut into' minirectangular bars (about '45 grams each). The bars are enclosed in foil-laminated white cartons and aged at room temperature for 2-4 weeks. The bars are then rated for odor intensity, odor quality and any discoloration that may have taken place. Perfumery materials which satisfactorily cover the normal soapy base odor without causing significant discoloration of the bars are judged useful for incorporation in soap bar perfumes as well as in perfumes for use in alkaline detergent products.
The detergent compositions of the invention are thus provided with perfumery materials which are unaffected in their stability toward alkali or chlorine releasing bleach agents, which stability properties are not possessed by many present day perfumery materials. Any undesirable odors present in the detergent compositions of the invention are thus masked by the pleasant fragrances or notes of the tetrahydropyran and tetrahydrofuran ether and ester perfumery ingredients. Moreover, the tetrahydropyran and tetrahydrofuran ether and ester perfumery ingredients can be very readily prepared by simple conventional chemical means and at a relatively inexpensive cost.
It will be appreciated that various modifications and changes can be made in the products of the invention by those skilled in the art without departing from the essence of the invention and that accordingly the invention is to be limited only within the scope of the appended claims.
