Definitions

  • the present invention relates to soap and sopa-synthetic detergent bar compositions and more particularly to bar compositions containing selenium disulfide.
  • a solid soap bar containing between 2% and 25%, and preferably between 5% and 15% water and between 0.1% and 5%, and preferably between 1% and 2.5% of selenium disulfide, is privoded.
  • the bars may be provided as toilet soap bars or as abrasive bars.
  • the bars also contain up to about 35 and preferably between 20% and 30% of dicalcium phosphate.
  • the solid bars of the present invention are usually and preferably formed from the alkali metal salts of higher fatty acids, e.g., the sodium salts of fatty acids having 8- 22 carbon atoms and preferably 12-18 carbon atoms, such as sodium stearate, sodium laurate, sodium oleate, etc. Potassium salts may be employed provided that the finished bar is of suitable hardness and acceptable solubility.
  • Amine and ammonium soaps may find limited a-pplication as minor constituents of the soap mixture.
  • the fatty acid portion of the soap may be a mixture of saturated and unsaturated acids obtained from the usual soapmaking fats such as coconut oil and tallow or maybe a relatively pure fatty acid or mixture such as commercial stearic acid.
  • the preferred soaps are those predominantly sodium base soaps prepared from mixtures of substantially saturated fatty acids derived from tallow and from coconut oil and their hydrogenated materials.
  • the preferred soap making compositions are those that contain a ratio of coco to tallow derived fatty acids from about 1:9 to 1:1.
  • the solid bars of the present invention may contain up to about 60% of a synthetic detergent, although it is preferred that soap comprise the major portion.
  • the soap-synthetic detergent bars may contain -60% of soap and 10:60% of synthetic detergent.
  • the synthetic detergent should be a water-soluble solid.
  • Preferred detergents include the sulfated fatty alcohols, particularly those containing about 10 to 22 carbon atoms.
  • Other suitable detergents include 3,340,196 Patented Sept. 5, 1967 the water soluble higher fatty mono-glyceride mono-sulfates, and broadly the class of solid detergents designated as water-soluble salts of organic sulfonic acids and of aliphatic sulfuric acid esters.
  • Theselenium disulfide is available in the form of fine particles. A very fine commercial grade averages between 5 and 20 microns and a coarser commercial grade averages between 50 and 200 microns. These fine particles, usually in suspension in a liquid, are added to the soap or soap-synthetic detergent components of the desired bar during the mixing step. The selenium disulfide is uniformly incorporated into the soap. It does no affect the color or appearance of the soap. However, it has been found that when bars containing selenium disulfide are heated in an oven for several hours or when aged at room temperature for long periods of time there is a tendency for discoloration to appear.
  • this may be taken advantage of to form a bar having a speckled purplish appearance.
  • This discoloration is prevented by incorporating in the bar, an effective amount of dicalcium phosphate (Cal-IP0).
  • the anhydrous dicalcium phosphate is pre-ferred.
  • the hydrated form is also effective, although slightly higher levels are required.
  • the bars should contain between about 20% and about 35% of the dicalcium phosphate.
  • Thos bars containing between about 20% and 30% are prefered.
  • the dicalcium phosphate available may be of sufficiently coarse size that the bar has mildly abrasive characteristics. These are desirable in combination with the therapeutic effect of the selenium disulfide in application to the skin.
  • the bars may, and usually will, contain several optional ingredients such as perfumes, preservatives, pigments, emollients, antiseptics, sequestering agents, antioxidants, stabiliziers, fillers, and abrasives.
  • optional ingredients include menthol, stannic chloride solution, long chain liquid organic phosphates, hexachlorophene, trichlorocarbanilide, insoluble sodium metaphosphate, zinc chloride, lanolin,titanium dioxide, and hydrated alumina (an abrasive).
  • the selenium disulfide is readily and uniformly incorporated in the soap mixture (or soap-synthetic detergent mixture) at the time the bar-forming components are mixed.
  • the basic soap may be supplied as the dry soap chip and the remaining ingredients including the desired amount of water added. Alternatively a wet mixture of the ingredients may be mixed and dried to the desired water content.
  • the mixed components are then placed in the hopper of a soap mill which contains at least three rolls and processed through the mill at least three times producing a ribbon.
  • the ribbon is processed in a soap plodder, and extruded, cut into lengths and pressed into cake form.
  • the bars of the examples were prepared by hand mixing the solid soap chips and the other solid ingredients, such as the selenium disulfide and alumina.
  • the liquid compo nents such as the perfume, the preservative and the added water, were springled individually over the surface of the 3 mixed solids.
  • the entire mass was .then mixed with spatulas and when thoroughly mixed placed in the hopper of a three-roll soap mill and passed through the mill to produce ribbon. These were hand mixed and returned to the hopper twice, to obtain a total of three passages through the mill.
  • the mill was at ambient tem eratures.
  • the ribbon products of the mill were then passed twice through an extrusion plodder.
  • the extruded strips of soap were cut into lengths suitable for insertion into a die in a press, inserted into the die and pressed into bars.
  • Example 1 A bar was, prepared from the following components:
  • Example 2 A bar similar to that of Example 1 and containing 25 of dicalcium phosphate, was found vto provide a bar which was very mildly abrasive:
  • Example 3 Another abrasive bar was prepared from the following components:
  • Example 4 The following components are mixed and processed to form a bar:
  • the soap bars of the present invention are applied to the body, e.g., the scalp, as a lather and the lather may be allowed to remain for several minutes in contact with the body, and then rinsed 01f leaving a desirable cleansing efiect on the hair and scalp.
  • a detergent composition in bar form consisting essentially of 10 to 60% of a solid water soluble alkali metal salts of the higher fatty acids, between 2% and 25% water, between 0.1% and 5% of selenium disulfide in homogeneous dispersion in said bar, and sufiicient up to about 35% of dicalcium phosphate effective to prevent discolor ation of the bar when aged at room temperature for periods of time.
  • the detergent bar of claim 1 containing between 5% and 15% water and between 1% and 2.5% of selenium disulfide.
  • the detergent bar of claim 1 containing between 20% and 30% of dicalcium phosphate.
  • a detergent composition in bar form as defined in claim 1 which contains from 10 to 60% of at least one water soluble anionic synthetic detergent.
  • the detergent composition of claim 4 containing between 5% and 15% water.
  • the detergent composition of claim 5 containing between 1% and 2.5% selenium disulfide.
  • the detergent composition of claim 6 containing between 20% and 30% of dicalcium phosphate.
