DETERGENT.

No Drawing.

New York, and State of New York, have invented new and useful Improvements in Detergents, of which the following is a full, clear, and exact specification. Our invention relates to detergents and refers particularly to detergent soaps.

We have found that cymene and the salts of the sulphoacids of cymene possess extraordinary and highly valuable detergent properties capable of practical application in the production of soaps and similar products. The value of these products for detergent purposes is enhanced by our discovery that they are soluble in saponaceous bodies, thus making them suitable for incorporation with saponified fat and saponified oil soaps with the production of products having detergent values greatly in excess of the soaps not so incorporated. I i

Without entering into a discussion of the several theories regarding the chemical and physical conditions and reactions incident to detergent bodies and their use, we,would state that cymene and these cymene compounds have the characteristics of colloids, possessing high viscosity and low surface tension, in addition to which they possess strong emulsifying properties. i

We have found that cymene and the salts of the sulphoacids of cymene may be incorporated with saponaceous bodies, either after, or during, their emulsification, producing resulting compounds, or mixtures, possessing high detergent, antiseptic and germicidal properties. e

We have further found that cymene and 41 the salts of the sulphoacids of cymene have strong odor destroyin properties and that their use in conjunctlon with odoriferous saponaceous bodies will destroy the odors, thus producin odorless, or practically odorless, compoun s. 7

Application filed August 26, 1921.

Serial No. 495,760.

We have found, for example, that when 2% of sodium cymene sulphonic acid are added to a soap composed of saponified fat, the detergent properties of the original saponified fatshave been increased 65% and that, at the same time, the resulting product is odorless, antiseptic and ermicldal, thus possessing greatly increased value over the original saponified fats.

The addition of cymene and the salts of the sulphoacids of cymene will convert soft soaps, such as oleic acid soaps, into hard soaps, irrespective of whether the cymene or the salt of the sulphoacid of cymene is added during, or after, the production of the soap. This is a most valuable attribute of these chemicals.

By cymene we mean either the chemically, or commercially, pure cymene, or the crude cymene-of the waste sulphite turpentine, obtained as a by-product in the production of paper. 1

By salts of the sulphoacids of cymene we mean those salts of the mono-, or multi-, sulphoacids of cymene which are dissolvable, or miscible, with the particular saponaceous body with which they are employed, producing results having detergent powers greater than the employed saponaceous body.

Among the salts of the sulphoacids of cymene which we have found particularly valuable are the alkali salts, such as sodium,

potassium and ammonium salts of the sulphoacids, although other salts have valuable properties for particular uses.

For clearness of definition and classification, we employ the words cymene bodies in our claims to mean cymene and salts of the sulphoacids of cymene, as described A above.

. or one salt of a su phoacid of cymene, or'a mixture of several, may be employed and a singlesaponaceous body, or a mixture. of several, may also be employed WVe do not limit ourselves to the particular 2.
