Definitions

• This invention relates to textile treatment compositions. More particularly it relates to textile treatment compositions suitable for use in the rinse cycle of a textile laundering operation to provide fabric softening/static control benefits, the compositions being characterized by excellent softening, water dispersibility and storage properties after prolonged storage at both elevated and sub-normal temperatures.
• rinse-added fabric softening compositions contain, as the active component, substantially water-insoluble cationic materials having two long alkyl chains. Typical of such materials are di-hardened tallow dimethylammonium chloride, and imidazolinium compounds substituted with two tallow groups. These materials are normally prepared in the form of a dispersion in water and it is generally not possible to prepare such aqueous dispersions with more than about 10 % of cationic softener without encountering severe product viscosity and storage-stability problems. Although more concentrated dispersions of softener materials can be prepared as described in European Patent Application No.
• U.S. Patent 4 454 049 issued June 12, 1984 to MacGilp et al discloses concentrated liquid fabric softeners comprising substantial amounts at least . 10%, more typically about 30 -40%, of water miscible organic solvent.
• U.S. Patent 2 995 520 issued August 8, 1961 to Luvisi et al discloses the use of the acid salts of certain imidazoline derivatives for softening of fibrous materials such as cotton and paper.
• the treatment baths used for treating textiles contain from 0.001% to 1% of an acid salt of an imidazoline derivative.
• compositions of the present invention have excellent stability at both elevated and sub-normal temperatures, even under prolonged storage conditions. These compositions further provide excellent softening, antistatic and fabric rewettabifity characteristics across a broad range of fabric types.
• the present invention provides a stable aqueous dispersion comprising:
• compositions of the present invention are based upon the discovery that stable aqueous dispersion can be formulated with certain cyclic amines, even at high amine concentration, and a conventional di(higher alkyl) quartemary ammonium salt, without the use of substantial amounts of organic solvent.
• compositions of the present invention are selected from the group consisting of:
• compositions of the present invention comprise from 1 % to 40% by weight of the amine, preferably from 2% to 35%, and more preferably from 2% to 20%.
• the dispersions herein contain a conventional di(higher alkyl) quaternary ammonium softening agent.
• “higher alkyl” as used in the context of the quarternary ammonium salts herein is meant alkyl groups having from 8 to 30 carbon atoms, preferably from 11 to 22 carbon atoms.
• Examples of such conventional quaternary ammonium salts include (i) acyclic quaternary ammonium salts having the formula: wherein R 2 is an acyclic aliphatic C 15 -C 22 hydrocarbon group.
• R 3 is a C 1 -C 4 saturated alkyl or hydrox- yaikyi group, R 4 is selected from R 2 and R 3 , and A is an anion.
• Component (i) are the well-known dialkyldimethylammoniums salts such as ditallowdimethylammonium chloride, ditallowdimethylammonium methylsulfate, di-(hydrodrogenated tallow) dimethylammonium chloride, distearyldimethylammonium chloride, dibehendyldimethylammonium chloride.
• Component (ii) are methylbis-(tallowamidoethyl) (2-hydroxyethyl) ammonium methylsulfate and methylbis(hydrogenated tal- lowamidoethyl) (2-hydroxyethyl) ammonium methylsulfate wherein R, is an acyclic aliphatic C 15 -C 17 hydrocarbon group, R 2 is an ethylene group, R 5 is a methyl group, R 8 is a hydroxyalkyl group and A is a methylsulfate anion; these materials are available from Sherex Chemical Company under the trade names Varisoft (R) 222 and Varisoft (R) 110, respectively.
• Examples of (iv) are 1-methyl-1-tallowamido-ethyl-2-tallowimidazolinium methylsulfate and 1-methyl-1 -(hydrogenated tallowamidoethyl)-methylsulfate.
• the weight ration amine (a): quaternary ammonium salt (b) is in the range from 10:1 to 1:10, preferably from 3:1 to 1:3.
• di(higher alkyl)imidazolinium compounds are preferred for use herein, in particular the 1-(lower alkyl)-1-(higher alkyl)amidoethyl-2-(higher alkyl)imidazolinium compounds, wherein “lower alkyl” signifies alkyl having from 1 to 4 carbon atoms, and “higher alkyl” signifies alkyl having from 11 to 22 carbon atoms.
• the dispersion may further comprise Bronstedt acids having a pKa value of 6 or less.
• suitable acids include the inorganic mineral acids, carboxylic acids, in particular the low molecular weight (C I- C s ) carboxylic acids, aromatic carboxylic acids, like benzoic acid, and alkylsulfonic acids.
• compositions of the present invention can be formulated without the use of any organic solvent.
• organic solvents - for example, low molecular weight, water mascible aliphatic alcohols, does not harm the storage stability, the viscosity, or the softening performance of the compositions of this invention.
• the amine will be obtained from a supplier of bulk chemicals in solid form of as a solution in an organic solvent, e.g. isopropanol. There is no need, whatsoever, to remove such a solvent in making the compositions of this invention. Indeed, additional solvent may be added, if this is deemed desirable.
• organic solvent e.g. isopropanol
• organic solvents are expensive, and difficult to handle because of their flammability and, sometimes, toxicity. It is therefore desirable to formulate the present compositions with low levels of organic solvent, i.e., less than 10%, preferably less than 2%.
• compositions herein can optionally contain an aqueous emulsion of a predominantly linear polydialkyl or alkyl, aryl siloxane in which the alkyl groups can have from one to five carbon atoms and may be wholly or partially fluorinated.
• Suitable silicones are polydimethyl siloxanes having a viscosity at 25°C in the range from 100 to 100,000 centistokes, preferably in the range from 300 to 6,000 centistokes.
• Silicones having cationic character show an enhanced tendency to deposit. Silicones found to be of value in providing fabric feel benefits have a predominantly linear character and are preferably polydialkyl siloxanes in which the alkyl group is most commonly methyl. Such silicone polymers are frequently manufactured commercially by emulsion polymerisation using a strong acid or strong alkali catalyst in the presence of a nonionic or mixed nonionic-anionic emulsifier system.
• the optional silicone component embraces a silicone of cationic character. which is defined as being one of
• the weight ratio of the siloxane to the amine component of the composition herein typically ranges from 5:1 to 1:100, preferably from 2:1 to 1:10.
• silicone component suitable for use herein are more fully disclosed in British Patent No. 1.549.180.
• compositions optionally contain nonionics as have been disclosed for use in softener compositions.
• nonionics and their usage levels have been disclosed in U.S. Patent 4,454,049, issued June 12,1984 to Mac Gilp et al., the disclosures of which are incorporated herein by reference.
• these compositions can contain relatively small amounts of electrolyte.
• a highly preferred electrolyte is CaCl 2 . It has been found that the Brookfield viscosities of highly concentrated dispersions can be reduced to less than 100 cps, using relatively small amounts of CaCl 2 (e.g., 600 ppm).
• compositions herein can optionally contain other ingredients known to be suitable for use in textile softeners.
• adjuvents include perfumes, preservatives, germicides, colorants, dyes, fungicides, stabilizers, brighteners and opacifiers. These adjuvents, if used, are normally added at their conventional levels
