Werk, and Theodor Hermann, Frankfort-on-the-Main Hochst, Germany, assignors to Winthrop Chemical Company, Inc., New York, N. Y., a corporation of New York No Drawing. Original application May 6, 1931, Serial No. 535,564. Divided and this applica-, tion August 13, 1936, Serial No. 95,840. In Germany May 30, 1930 3 Claims. The present invention relates to new water (01. 87-5) I Example 1.--To 80 parts of a neutral or acid soluble soaps, being compositions consisting of soap 20 parts of triphenyl-dichloro-benzyl-phos- ' neutral or acid soapy washing agents and moth phonium chloride are added, and the whole is proo?ng agents having an a?lnity for W001, said ‘intimately mixed. 5 soaps being suitable for cleaning and rendering moth proof Wool, feathers, hair and the like in one and the same process. - We mean by neutral washing agents, for in- stance, the neutral alkali salts of palmitic, stearic 10 and oleic acids as contained in the usual soaps and by acid washing agents, the alkyl esters of sulfurized castor oil or of sulfurized oleic acid or oleyl-methyl-amino-methane sulfonic acid or oleyl-hydroxy—ethane-suiionic acid (sodium salt) 5 or similar washing agents resistant to acid reaction. We mean by moth proo?ng agents having a?inity for W001 the salts of quaternary phos- 0 ~ phosphonium bases can be used either alone or mixed with another one, the quantity depending on the e?icacy of selected compounds. 10 parts of this special soap dissolved in 1,000 parts of 10 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 moth-proofed at the same time. Example 2.—To 80 parts of oleyl-methyl-ami- 1‘ no-ethane-sulfonic acid 20 parts of sodium-silico ?uoride are added, and the whole is intimately phonium bases such as triphenyl-dichloro-benzyl- mixed- phosphonium chloride, salts of hydro?uoric acid, hydro-silico-?uoric acid, hydro-?uoro-titanic acid, boro-?uoro-acetic acid, selenic acid, selenious acid or the free acids, aromatic hydroxy- Instead of sodium-silico-?uoride other acid 20 moth proo?ng- agents such as potassium-hydro ?uoride, boro-?uoro-acetic acid, acid salts of selenic acid canbe used.

The speci?c moth proo?ng agent incorporated with 40 the soapy Component depends on the chemical behavior Of Said soapy Component, which is more fully described hereafter. Thus, when using as moth-proo?ng agent the free selenic acid or selenious acid itself or acid or acid salts of hydro45 ?uoric acid or hydro-fluo-silicic acid or their soluble salts or suitable mixtures of the above agents, a soapy component resistant to the acid reaction is required, for example,‘ oleyl-methyl-aminoethane sulfonic acid, while the salts of quaternary 50 phosphonium bases may be combined with the neutral alkali salts of palmitic, stearic, oleic acid 1 and the like. The following c'zamples will illustrate our in- ' vention but without limiting it thereto. 55 parts are by weight. ' of 10 parts of this special soap in 1,000 parts of 25 water will be cleaned and moth proofed at the same time. Example 3.-80 parts of oleyl-hydroxy-ethane The new compositions are obtainable in a _ known manner by incorporating into such neu3O tral or acid washing agents moth proo?ng agents as above described. The new compositions thus produced are colorless or slightly colored-in the dry state, and are n, soluble in water. All these soaps, in the iorm "'2 of lumps, powders, pastes or solutions, can be \ - Instead of the triphenyl-dichloro-benzyl-phos- 5 phonium chloride also other salts of quaternary The sulfonic acid in the form of its sodium salt and 20 parts of dichloro-salicylic acid are intimately 30 mixed. Wool treated in a solution of 20 parts of such a soap in 1,000 parts of water is cleaned and ren dered moth proof in this way. Example 4.-—20 parts of bis-1.3-dichloro-ben- 35 zene-4-sulfo-1.3-phenylene-diamide are emulsi ?ed in 80 parts of the alkyl ester of sulfurized castor oil. Wool treated in a solution of 20 parts of such a soap in 1,000 parts of water at 60° C'. is cleaned 40 and rendered moth proof at the same time. A mixture of diiferent 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 45 to fur,‘care must be taken not to attack the skin. This application is a divisional application of our U, S. application Serial No. 535,564, which is now Patent No. 2,082,188, issued June 1, 1937. We claim: 50‘ 1. A moth-proo?ng detergent composition con sisting essentially of oleyl-methyl-amino-ethane sulfonic acid in preponderating proportion and sodium silico-?uoride, said composition being at the most only slightly colored in the dry state, 55 2,130,435 2 being soluble in water, and being adapted for simultaneously cleaning and rendering moth proof wool, feathers, hair and like materials. 2. A moth-proo?ng detergent composition con sisting essentially of the sodium salt of the oleyl hydroxyethane sulfonic acid in prepondering pro portion and potassium hydro?uoride, said com position being at the most only slightly colored in the dry state, being soluble in water, and be 10 ing adapted for simultaneously cleaning and rendering moth-proof 'wool, feathers, hair and like materials. ‘ 3. A moth-proo?ng detergent composition con sisting essentially of an acid soapy washing agent in'preponderating proportion and of a water soluble moth-proo?ng agent having an amnity for W001 selected from the group consisting of acid hydro?uoric acid salts, hydrosilico-?uoric acid, hydro?uoro-titanic acid, boro-?uoro-acetic acid, selenious acid, selenic acid, and salts of the said acids, said composition being at the most only slightly colored in the dry state, being sol uble in water, and being adapted for simultane ously cleaning and rendering mothiproof wool, 10 feathers, hair and like materials.
