Description

I wm ’ Ca ie i. The invention relates to fabric softening

I compositions adapted to be used in the rinse cycle ’ . of an automatic dishwashing machine. More partie Co oularly, this invention is concerned with aqueous . fabric softening compositions which impart improved ‘ softness and other desirable attributes such as bet tar rewettability to the compositions. Speciticale - : 1y, the invention is based on the combination’ of a ’ cationic softener and a unique class of polysiloxanes. - Compositions containing quaternary anmonium - salts having at least one long chain hydrocarboxyl : group such as distearyl dimethyl ammonium chigride or long-chain imidazolinkum salts are commonly used oo to provide fabric softening benefits when employed © 15 | in a laundry rinse operation: for example, see U.S.

Fat. Nos. 3,349,033) 3,644,2031 3,946:1151 3,997,453 4,073,735, and 4,119,545, among many others.

Cr The quaternary ammonium compounds, while . . they are salts, are nevertheless generally charace terized ae water-insoluble since their solubility in water under normal conditions is less than about 5%

Ce "by weight. The usual concentration used by the con- sumer and accepted as the "standard" is 6% by weight. }

“ wap : CE Xe gE % - 0 -

At this and higher concentrations these cationic salte are generally present as ngols" or dispersions, } and stability becomes =a major problem. See for exam- ple U.S. Pat. No. 5,526,299 col. 1, lines 11 to 22.

S As a matter of fact stability and viscosity problems become major ones at higher concentrations e.g. above about 7% by weight of the cationic. There have been : oo many proclaimed solutions to providing concentrated (1.0. 5 6-7%) stable cationic formulations within usable and consumer accepteble viscosity ranges e.g. 30 ops to 500 ops. Cee for example U.3. Pate. Nos. bh, 442,013 and 4,661,270. While such concentrated formulations may afford stable and acceptable vis- cosity products their softening characteristics of : 15 gourse at equivalent concentrations, are essentially the same as the 6-7% products. - . It is desirable to provide cationic soften= : | , ing compositions, particularly for use in the rinse ‘cycle of a clothes washing machine, which are of im- proved softening not only at equal concentrations | : with older formulations, but even at lower concen- trations. This concept is not new as evidenced e.g. by U.S. Pat. No, 4,000,077 to Wixon wherein cationic i quaternary softener is combined with alcohol or al- oohol ether sulfate. This patent also demonstrates

/ - that with improved softening, another plus is achieved in terms of enhanced whiteness, the late a “ aw ter often being adversely affected hy cationics. ;

Th Ee It has also been known to employ silicone . - 5 based composition for treating fibers or yarns and - . ‘textiles to soften them. See, in this regard, an / Co article in Colorage-June 29, 1972 entitled "Silicones in the Textile Industry" by H. J. pald p 46 and 53.

Also attention is directed to U.S. Pat. Nos. 3,968,042 and 4,020,212 wherein compositions of or- : oo gano polyxiloxane (and predominantly a poly [dimethyl siloxane/) with a cationic softening surfactant (e.g. distearyl dimethyl ammonium chloride) or conventional imidazolinium softener (Varisoft 475) are described for the treatment of polyolefin fibers. The organo polysiloxanes sre liquid, water-dispersible products with viscosities ranging from "about 100 to about

Co KOO" cps at 77°F. (25°C.). .

Co In British 1,549,180, combinations of cationic and silicone are described, with the silicone proe : | viding in addition to some of the previously known benefits as waterproofing agent and "ironing aids" anti-stat, soil release etc..., softening benefits as well, The silicones are siloxsnes with visco- 2% sities at 25°C. of "at least 100 centistokes and up

Cu vl . to B(XX) centistokes". While this patent appears

Limited to siloxanes with viscosities not abowe 8000 sentistokes disclosures of higher viscosities (e.g. up to 17000 centistokes) are given but data is given allegedly establishing optimum performance in the range of 3000 to 8000 cc. (Ex. 1). In other foreign patents corresponding to British, 1549180, such es French, 2318268, there is generally a similar disclosure but in addition additional examples are given (see also Canadian 1085563, 1102511 and 1118965) : indicating "high viscosity silicones may give supe= rior softeners'. . oo l Further reference is made to U.S. Pat. Nos 3,376,161 which discloses compositions of quaternary ammonium salts and polysiloxanes for impregnating ‘ fibrous material to impart "anti-scruff" charaoteris- : “tios. The only specific viscosity given for ‘a polysilo- ; : 1. Xane is 10,000 cs at 25° C. None of the priof art

Co ispectally in the laundry softener field discldaes a co 20 - copss-linked polysiloxane. J co It has now been discovered that improved softening compositions are provided by a combinae tion of a cationic softener or mixture of cationio . éofteners or mixtures of cationics with anionics (ego alcohol sulfates or alcohol ether sulfates)

The 11quids may have viseosities in the range of less : 8 Ahan about 100 40 several hunired to several thousand to the tens of thousands and up to where it becomes urmeseur- able} the preferred polyeiloxnnes have viscosities about 10,000 cs (25%. ) up to elastomeric types (1.8. no messur- . able viscosity). : The compositions of this invention not only give superior softering, but quite unexpectedly yield treated textiles with improved rewsttebility: : : As 12 well mown, the ontioniec softeners tend to pro- vide Patrios with a degree of wnter-recietmmee or in other 18 words these softensrs tend to render the fabric somewhat hydrophobic, Silicones (or polywiloxanes) also would be - expboted to increase the hydrophobicity of fabrics treated with then as described in British 1,549,180, Notwdihwtend- ne nach tenchings snd expeotations it has now been dis- covered that the compositions of this invention not oly ‘provide improved end outstanding softening of textile es- pecially in the rinse oyole of a washing machine but also do #0 without incrensing the hydrophobicity of the textile.
