Description:

2,184,951 MOTHPROOFING DETERGENT COMPOSITION Hermann Stotter, Leverkusen I. G. Werk, and Theodor Hermann, Frankfort-on-the-MainHochst, Germany, assignors to Winthrop Chemical Company, Inc., New York, N. Y., a corporation of New York No Drawing. Application August 13, 1936, Serial No. 95,840, now Patent No. 2,130,435, dated September 20, 1938, which is a division of application Serial No. 535,564, May 6, 1931, now Patent No. 2,082,188, dated June 1, 1937. Divided and this application June 8, 1937, Serial No. 147,036. In Germany May 30, 1930 3 Claims. (CI. 87-5) The present invention relates to new watersoluble soaps, being compositions consisting of acid soapy washing agents and organic mothproofing agents having an affinity for wool, said soaps being suitable for cleaning and rendering mothproof wool, feathers, hair and the like in one and the same process.

We mean by acid washing agents, the alkyl esters of sulfurized castor oil or sulfurized oleic acid or oleyl-methyl-amino-methane sulfonic acid or oleyl-hydroxy-ethane-sulfonic acid (sodium salt) or similar washing agents resistant to acid reaction. We mean by organic mothproofing agents having affinity for wool the salts 16 of quaternary phosphonium bases such as triphenyl - dichloro - benzyl-phosphonium chloride,. aromatic hydroxy-carboxylic acids or their halogenated substitution compounds, and aryl-sulfamldes, in which hydrogen atoms connected to the nitrogen atom of the amino group can be replaced by alkyl or aryl radicals.

The new compositions are obtainable in a known manner by incorporating into such neutral or acid washing agents mothproofing agents as above described.

The new compositions thus produced- are colorless or slightly colored in the dry. state, and are soluble in water. All these soaps, in the form of lumps, powders, pastes or solutions, can be 80o used for simultaneously cleaning and mothproofing materials liable to attack by moths.

The following examples will illustrate our invention but without limiting it thereto. The parts are by weight.

To 80 parts of a neutral or acid soap 20 parts of triphenyl-dichloro-benzyl-phophohnium chloride are added, and the whole is intimately 40 mixed.

Instead of the triphenyl-dichloro-benzyl-phosphonium chloride also other salts of quaternary phosphonium bases can be used either alone or mixed with one another, the quantity depending 45 on the efficacy of selected compounds. 10 parts of this special soap dissolved in 1000 parts of water are used for washing woolen material in the customary manner at about 40 to 50' C. The material treated in such a manner is cleaned and 50 mothproofed at the same time.

Example 2 80 parts of oleyl-hydroxy-ethane-sulfonli acid in the form of its sodium salt and 20 parts of dichloro-salicylic acid are intimately mixed.

Wool treated in a solution of 20 parts of such a soap in 1000 parts of water/is cleaned and rendered mothproof in this way.

Example 3 20 parts of bis-1.3-dichloro-benzene-4-sulfo1.3-phenylene-diamide are emulsified in 80 parts of the alkyl ester of sulfurized castor oil.

Wool treated in a solution of 20 parts of such a soap in 1000 parts of water at 60* C. is cleaned and rendered mothproof at the same time. A mixture of different soaps may be applied, and the process may be varied within wide limits according to requirements. It will be, of course, understood that when the new process is applied to fur, care must be taken not to attack the skin. This application is a divisional application of our U. S. application Serial No. 95,840, filed August 13, 1936, now Patent No. 2,130,435, issued September 20, 1938, which on its part, is a divisional I application of our U. S. application Serial No. 535,564, filed May 6, 1931, now Patent No. 2,082,188 issued June 1, 1931.

We claim: 1. A mothproofing detergent composition consisting essentially of an acid soapy washing agent in preponderating proportion and a water-soluble organic mothproofing agent having an affinity for wool selected from the group consisting of salts of quaternary phosphonium bases, aromatic hydroxy-carboxylic acids, the halogen-substituted products of the latter, aryl sulfamides and derivatives thereof in which hydrogen atoms connected to the nitrogen atom of the amino group are replaced by aryl or alkyl radicals. 2. A mothproofing detergent composition consisting essentially of an acid soapy washing agent in preponderating proportion and triphenyldichloro-benzyl phosphonium chloride, said com- 45 position being at the most only slightly colored in the dry state, being soluble in water, and being adapted for simultaneously cleaning and rendering mothproof wool, feathers, hair and like materials. 3. A mothproofing detergent composition consisting essentially of the sodium salt of oleylhydroxyethane sulfonic acid in preponderating proportion and dichloro-salicylic acid, said composition being at the most only slightly colored in the dry state, being soluble in water, and being adapted for simultaneously cleaning and rendering mothproof wool, feathers, hair and like materials.
