Abstract: A method for stabilizing a cosmetic composition containing carrageenan, specifically, a toothpaste, wherein microwave radiation, preferably in the 0.8 to 3 gigahertz frequency range, is directed onto the toothpaste so as to raise its temperature to at least the gel-sol transition temperature of the carrageenan, after which the toothpaste is quiescently cooled to room temperature. The use of microwave radiation facilitates an even heating of the toothpaste, so that temperature sensitive components thereof are not adversely affected, and promotes excellent control of temperature regulation. Heating of the dentifrice, with improved thickening and stabilization thereof, is obtainable by passing it through a conduit while directing microwave radiation onto it and then filling it into suitable dispensing containers, or by filling the dentifrice into such containers and then subjecting them to microwave radiation.

Abstract: A process for the elimination of wet surface cracking in dual extruded soaps including the steps of extruding two streams of plodded soap from a single cone dual extrusion nozzle, cutting the two streams of plodded soap at right angles to the extrusion axis to form plodder soap blanks or billets of a predetermined size, rotating the plodder soap blanks or billets 90.degree. on the extrusion axis, introducing the rotated plodder soap blanks or billets into a soap press having movable die elements so that the transverse faces of the plodder soap blanks or billets are in registry with the movable die elements, pressing the rotated plodder soap blanks or billets on their transverse faces to form pressed soap bars, and removing pressed soap bars. The process provides soap bars having an essentially laminar or parallel stress pattern.

Abstract: A particulate fabric softening detergent composition comprises certain proportions of synthetic organic detergent, builder salt, bentonite (preferably a swelling Wyoming bentonite) and water insoluble soap (preferably aluminum stearate). The detergent composition preferably comprises spray dried built detergent beads with which are blended agglomerated beads of the bentonite and water insoluble soap. The combination of water insoluble soap and bentonite greatly increases the softening action of the composition when it is employed for hand washing of laundry.

Abstract: A method of facilitating the incorporation of hydroxypropyl methyl cellulose (HPMC) into a liquid formulation containing water which comprises:1. forming a liquid premix of hydroxypropyl methyl cellulose dispersed in an aqueous-free organic liquid medium in which it does not swell or dissolve, selected from the group consisting of liquified nonionic surfactants, fatty acids, anionic surfactants and mixtures thereof, by dispersing HPMC in said liquified organic medium with mild agitation;2. adding said premix to an aqueous-containing liquid formulation and dispersing therein by means of a short mixing cycle as short as 5-10 minutes. This method has particular utility in the preparation of liquid shampoos, liquid dishwashing detergents, liquid hand soaps and other aqueous-containing liquid formulations wherein it is desirable or necessary to include hydroxypropyl methyl cellulose as a viscosity modifier.

Abstract: An absorbent article comprising a backing sheet of fluid impervious material, a fluid pervious cover sheet, and a first pad adjacent the cover sheet comprising a loosely formed fibrous mass. A separate second pad may be positioned intermediate the first pad and the backing sheet, with the second pad comprising a mass of fibers having compressed regions extending throughout a substantial part of the second pad. A polymer coating in the target area extends at least most of the width of the pads and extends between the third and the sixth tenth of the length of the pads. The polymer may be present on the top surface of the first pad (i.e. surface adjacent cover (top) sheet) and/or between the first and second pad and/or on the bottom or back surface of the second pad. Where only one pad is used, the polymer may be present on both the top and bottom surfaces thereof.
