Embodiment 1

[0150] This example will demonstrate the effect of the concentration of active softening components (A) and (B) on the viscosity of softener compositions for compositions formulated in accordance with US Patent 5,501,806 (Farooq et al.). A 75 / 25 weight ratio (Varisoft 510 / Varisoft 511 ) mixture of the aforementioned Varisoft-510 and Varisoft-511 was used as component (A) in the composition. Component (B) is a diester quaternary ammonium compound (DEQ) Tetranyl AT-75 from Japan Kao Company, which is named methyl triethanolamine-tallow diester methyl sulfate quaternary ammonium salt. The alkyl hydrocarbyl in DEQ is based on approximately 75% soft tallow and 25% hard tallow. Thus, based on soft tallow having about 45% unsaturated alkyl chains, the DEQ product contains about 34% unsaturated alkyl chains (45 / 100 x 75). In the formula shown in the following table 1, component (A) (amidoamine) and component (B) (DEQ) are included, and its weight ratio is (A): (B)=1.67: 1, so the com...

Embodiment 2

[0156] This example demonstrates that, except softening compositions (A) and (B) which do not contain unsaturated hydrocarbon groups (contrary to the requirements of the present invention), other softening compositions formulated according to the present invention suffer from gelling problems at higher concentrations. Liquid compositions containing more than 35% by weight active ingredient cannot be formulated.

[0157] The compounds shown in Table 2 were prepared using Varisoft 510 as the amidoamine component (A) and Hiopchem X-89107 from High Point Chemical Company as the diesterquat component (B) (the tallow portion of which was 100% saturated). Composition 6. Method of Preparation According to the present invention, the oil phase portion containing (A) and (B) is heated to 70° C. and then mixed with the water phase portion containing PEG polymer and HCl in a glass container by stirring to form a thick emulsion. Stirring was provided by a propeller stirrer with three 7 cm ...

Embodiment 3

[0160] This example will demonstrate that compositions having an active material concentration of greater than 35% by weight can be prepared in accordance with the present invention and still remain easy to pour and provide effective softening.

Abstract

Super-concentrated liquid rinse cycle fabric softeners are provided which contain more than 35 %, by weight, of a fabric softening system based on an amidoamine fabric softener, such as bis(tallow amidoethyl)-2-hydroxyethyl amine and a quaternary diester fabric softener, such as N-methyl, N,N,N-triethanolamine ditallow ester quaternary ammonium salt. A fatty alcohol ethoxylate surfactant and a polyethylene glycol polymer or a polyethylene glycol alkyl ether polymer are integral components of the liquid composition. The super-concentrated compositions may be used at low levels or may be further diluted prior to use.

Description

field of invention [0001] The present invention relates to liquid fabric softening compositions. More particularly, the present invention relates to ultra-concentrated liquid fabric softening compositions which are effective for softening fabrics in both soft and hard water and which are primarily intended for use as rinse-process fabric softening compositions as a reduced dosage Undiluted concentrate for ready-to-use products, or as a product to be diluted with water before use, so that it can be used in the same amount as a regular ready-to-use product. Background of the invention [0002] Compositions containing quaternary ammonium salts or imidazolinium compounds having at least one long chain hydrocarbyl group are commonly used to provide fabric softening benefits when in the rinse operation of laundry. Numerous patents have been filed on these types of compounds and compositions. [0003] Recently, however, many conventional formulations have been...
