ABSTRACT A hydrophilic gel of a polymeric fat acid polyamide. and a diethanolumide of a fatty acid or a branched chain fatty acid.
14 Claims. N0 Drawings WASHING POLYMERS This invention relates to polymerized fatty acid poly amides and diethanolamide of fatty acids which can be used as detergent and detergent soap type washing polymers.
More particularly. this invention relates to washing polymers in the form of gels derived from polyamide resins which may be either transparent, translucent r opaque and which have many properties that make them unique.
As used herein. the term gel" is meant to include hydrophilic compositions which range from solids to liquids of the type encountered in the liquid household detergents. However, the viscosity of the composition of this invention is readily controlled during processing depending upon the use desired for the composition.
When practicing a preferred embodiment of this invention, a washing polymer is obtained by mixing. while heating. 0.5-95 parts by weight of a polymeric fat acid polyamide. preferably polymerized tall oil fat acid polyamide, and l-95, preferably -80, and most preferably 25-60. parts by weight of a fatty acid compound such as diethanolamide of a fatty acid or a branched chain fatty acid neutralized with dior tri-ethanolamine or mixtures thereof. The dicthanolamide of the fatty acid or the branched chain fatty acid contains 6-22 carbon atoms, preferably 8-12 carbon atoms. The polymeric fat acid polyamidc and either the diethanolamide or the branched chain fatty acid are heated to the melting point of the polyamide and then held for a period of time, up to 4 hours, preferably -30 minutes, at the melting point of the polyamide. The heated mixture is allowed to cool and form a gel which can be used as a washing polymer.
The subject matter of the present invention is substantially disclosed in applicants US. Pat. No. 3,654,167, dated Apr. 4, 1972. which patent is incorporated by reference herein.
In the aforesaid US. Pat. No. 3,654,167, the disclosure and claims indicated that it was necessary to use 5-95 parts by weight of a polymeric fat acid polyamide. It has now been found that the desired results are also satisfactorily obtained when the proportion of the polymeric fat acid polyamide is as low as 0.5 parts by weight.
The following examples illustrate other compositions embodying the present invention in addition to those disclosed in the aforesaid US. Pat. No. 3,654,167:

The same procedure is used as in Examples 1 and 2 except that the temperature of the mixture of the first three components is first brought down to about C, at which temperature the polyethylene granules are added with agitation. The mixture is then cooled to room temperature. The resultant product. wherein the polyethylene granules are suspended in the gel, may be most satisfactorily used as an acne scrub.
EXAMPLE 4 Components Parts by Weight Versalon 1200 "Standopol 7021 Concentrate The same procedure is used as in Example 1 except that the Versalon 1200" is substituted for the Emerez 1530". The resultant product is a flowable gel; that is, although it does not pour like water, if the fingers are inserted therein it feels like a liquid. It has the consistency of a Carbopol type or free-flowing,
The first three components are heated to at least the melting point of the Versalon 1200", preferably about C. It is held at that temperature for about 1 hour. The Standopol 7021 Concentrate" is then added with agitation. The mixture is then cooled with agitation to about 65C. at which time it is poured into a mold or tube where it is permitted to cool to room temperature.
