Definitions

  • This invention relates to the manufacture of soaps which are especially adapted for dissolving fats, oils, resins and contaminations of any kind.
  • "F or this purpose it has been proposed to incorporate chlorinated hydrocarbons in a water-soluble form into soap, and such preparations which are put up for sale in the form of liquids have been used to a great extent in textile industries. However, they have not been adopted ,in households and workshops for-the following reasons. v
  • monoalkyl ethers for instance, diethyleneglycol, triethyleneglycol and mixtures there'- of.
  • C H OHOR for instance, an ethylene-, propyleneor butylene-glycolether
  • ethers of polyethyleneglycols which are good solvents for certain substances, such as fatty oils of vegetable or animal origin or mineral oils and resins,.soda or potash soaps are obtained having an increased cleaning capacity.
  • the said-ethers are soluble in water and this property also belongs to the aqueous solutions of such soaps.
  • glycolmonoalkylethers are easily soluble in glycolmonoalkylethers; their solubility is increased bya small addition of water. Therefore glycolmonoalkylethers may be mixed within wide limits with var ing amounts of potash oaps to form liqui or jelly-like products.
  • a further advantage consists in that no- Soda soaps are, as a rule, rather. diflicultly soluble in the liquid glycolmonoalkylethers when cold; they are more soluble at temperatures from about to 100 C. In this case the solubility may also be increased by a slight addition of water; Even with a small percentage of soap, amounting to about I have further found that the presence of i the said. glycolor polyglycolethers in, the soap facilitates the incorporation of numerous other fat-solvents, such as liquid hydrocarbon compounds, including their halogen substitution products as, for instance, chlorinated hydrocarbons of, the aliphatic, aromatic or hydroaromatic series. By varying the proportions of the ingredients (including water) either solid or jelly-like or unguentary products may be obtained.
  • the new soap I may pro ceed in such a way that the soda or potash soap or the soap-paste is first stirred with the glycolether at temperatures from about 50 to 100?" G. and then the other ingredients are added in'a closed vessel, stirring'and heating being continued. Thereafter the mass is allowed to solidify or to gelatinize, as the case may be.
  • the said-'glycolethers or polyglycolethers and the liquid hydrocarbon compounds may be added to the finished soaps, or the ethers and, if desired, also the other ingredients or mixtures or both may be added or incorporated to the raw materials from .which the soap is produced.
  • the final products are distinguished by-the same qualities as the products obtained by adding the same ingredients to the finished soap, but are es-/ pecially characterized by their strong frothing or lathering power andby their agree-.
  • the abovenamed ethers are not attacked, ⁇ when present while the process of saponifying oils or fats is performed.
  • I may proceed in such a way that the fat or oil to be saponified is first dissolved in the ether to be employed, then the saponification is effected and thereafter, if desired, a li uid hydrocarbon or a liquid chlorinated hy rocarbon is added.
  • a li uid hydrocarbon or a liquid chlorinated hy rocarbon is added.
  • glycolalkylethers have a higher boiling point than the liquid hydrocarbons o-r chlorinated hydrocarbons employed, the former perform the action of decreasing the vapor tension of the latter whereby the smell of the preparations is reduced to such a degree that it is no longer perceived as offensive when using the products.
  • the slight proper odour of the ethers does not appear at all.
  • glycolalkylethers and the (individual or mixed) polyglycolalkylethers are furthermore characterized by the fact that they largely repress the feeling of fat-extracting from the skin.
  • the properties of soaps even containing, for instance, more than 30% of chlorinated hydrocarbons are altered to such an extent that no roughness or hardness of the skin is brought about, but on the contrary the skin gets a soft, tender and pliable character which is preserved unchanged even after repeated washing.
  • the new soaps are distinguished by a superior cleaning power, as glycerine is no solvent for fatty oils, resins and the like.
  • Soda soaps may be produced according to my invention and pressed into moulds.
  • Emamples 1 250 parts of soft soap are, at temperatures from about 50 to 100 C. mixed, while stirring, with 40 parts of glycolmonobutylether, and, while further stirring, 200 parts of carbon tetrachloride are added. The appearance of the soft soap remains unaltered. On dissolving the product in water, no carbon tetrachloride is separated.
  • potash 0r soda soaps a mixture of both may be used.
  • cocoa-nut fat 100 parts are dissolved in a mixture of 60 parts of glycolmonoethyh ether and 90 parts of carbontetrachloride. Then the fat is saponified with 52 parts of a hot caustic soda solution showing 38 B. On cooling-down, the product solidifies as a hard soap.
  • cocoa-nut fat 100 parts are dissolved in a mixture of 60 parts of glycolmonoethylether and parts of tetraline.- Then the fat is saponified with 52 parts of'a caustic soda solution of 38 B while heating. On cooling-down, the product solidifies as a hard soap.
  • cocoa-nut fat 100 parts are dissolved in a mixture of 60 parts of glycolmonoethylether and 60 parts of toluene. Then the fat is saponified with 52 parts of a caustic soda solution of 38 B while heating. After cooling-down, the mixture solidifies as a hard soap.
  • cocoa-nut fat 100 parts are dissolved in a mixture of 60 parts of glycolmonoethylether and 60 ports of benzene.
  • the fat is saponified with 52 parts of a caustic soda droca'rbon compound wherever it occurs in the following claims is to include those hydrocarbons and their halogen substitution products which are in common use as volatile solvents.
  • a soap containing a monoalkylether of the group comprising glycols and polyglycols and a'liquid chlorinated hydrocarbon As a new article of manufacture and trade, a soap containing a monoalkylether of the group comprising glycols and polyglycols and a'liquid chlorinated hydrocarbon.
  • a soap containing a monoalkylether of the group comprising glycols and polyglycols and carbon tetrachloride As a new article of manufacture and trade, a soap containing a monoalkylether of the group comprising glycols and polyglycols and carbon tetrachloride.
  • the product solidifies forming a hard soap.
