Abstract:
Described is a mixture for producing a combi-bar floating in water at 20° C. (floating combi-bar), the mixture comprising or (essentially) consisting of: v) 20-50 wt. %, preferably 25-40 wt. %, of one or more non-soap surfactants, preferably solid non-soap surfactants, vi) 25-60 wt. %, preferably 35-55 wt. %, of one or more free C14-C18 fatty acids, vii) 2-40 wt. %, preferably 5-25 wt. %, of one or more metal C8-C24 fatty acid soaps, and viii) 0-20 wt. %, preferably 2-20 wt. %, of further ingredients, said mixture containing less than 10 wt. % of water as a further ingredient. Further described are methods for producing a combi-bar and a combi-bar itself.
Abstract:
A process for the manufacture of aerated solid shaped detergent compositions comprising the steps of: i) preparation of a melt of the detergent composition to be cast; ii) addition of fatty alcohol to the melt either prior to or after the air or gas has been incorporated into the melt; iii) mixing the melt in a high shear mixer; iv) pouring the melt into a mould; v) cooling the mould; vi) demoulding the solidified-shaped article. Preferably, the detergent composition comprises 20% to 60% by weight of detergent active, 0.1% to 10% by weight fatty alcohol and 30% to 60% by weight water and/or polyhydric alcohol.
Abstract:
A slip-resistant floating bar soap having two outer convex-shaped layers of soap connected to an inner layer of concave-shaped rigid water-impermeable buoyant material having an exposed slip-resistant outer surface extending around the outer perimeter of the floating soap bar to provide a gripping surface for the hand of the user to aid in preventing the floating soap bar from slipping from the hands of the user.
Abstract:
A machine dishwashing detergent composition is disclosed. The composition includes delayed-release solid particles comprising at least one ingredient that is intended to perform its function during the rinse cycle of an automatic dishwashing cycle wherein the particles float in water and have no more than one dimension bigger than 1 cm.
Abstract:
An elastic detergent bar of improved elevated temperature stability, so that it better maintains its shape on storage at temperatures somewhat higher than normal, includes an amphoteric synthetic organic detergent in mixture with an anionic synthetic organic detergent, gelatin, water and insoluble gas in very small bubble form distributed throughout the bar. The bars are substantially form-retaining during storage and although they wear away during use, substantially retain their initial forms and elasticities for major proportions of their useful lives. Compared to similar bars in which the insoluble gas, such as air, is not present, the invented bars are stable at higher storage temperatures, e.g., 5.degree. to 10.degree. C. higher, making them commercially much more acceptable. Additionally, the elastic detergent bars are resistant to breakage during shipment and use, exhibit less surface tackiness than similar control bars, are very easily molded to finely figured and detailed shapes and of course, because of their lower density, float. Also within the invention is a process for making the described products.
Abstract:
A bar element intended for personal washing use only once or a few times, after which minimal soap remains on the element. The soap bar element includes an inexpensive, preferably inert, core supporting a relatively thin shell of soap. The core may be formed of any convenient material, such as rigid or foam polyurethane or polystyrene, or of water-soluble or biodegradable material such as oxycellulose polymers. The soap may be any solid soap material. The core may extend through one or more surfaces of the soap shell. The core comprises at least about 25%, and preferably greater than about 80%, by volume of the bar element.
Abstract:
The invention relates to washing or cleaning agent shaped bodies that are mechanically stable, have an excellent rate of dissolution and a completely novel appearance. The novel washing or cleaning agent shaped bodies comprise solid(s) and gas(es) and optionally other washing or cleaning agent components. The shaped body consists of gas-filled cells (pores) that are defined by solid dividing walls. Preferred washing or cleaning agent shaped bodies in the form of solid foams have a content of 40 to 90% by weight of one or more water-soluble polymers, 10 to 60% by weight of one or more substances from the group of builders, acidifying agents, chelate complexing agents, plaque-inhibiting polymers or non-ionic tensides as well as 0 to 50% by weight of one or more adjuvants and/or fillers.
