Definitions

• This invention relates to a fabric softening preparation and more particularly to a fabric softening preparation for use in drying tumblers.
• a fabric softening preparation for use in drying tumblers.
• Such a treatment is ordinarily carried out by adding an aqueous emulsion of a softening composition (rinsing composition) to the last portion of rinsing water.
• softening compositions which are used for this purpose are quaternary ammonium compounds having the general formula
• R R R R N X in which R and R are lower al kyl groups and pre-
• R and R are higher al kyl groups, such as stearyl groups, and wherein X is Cl or Br .
• quaternary ammonium compounds do not only exert a softening effect on the fabrics but also counteract the charging of such fabrics with static electricity. Therefore, they are particularly suitable for the treatment of fabrics containing synthetic fibres.
• the supply of softening compositions to a fabric through the rinsing water may present dosage problems .
• the required amount of softening composition does not only depend on the weight of the fabric but also on the type of fibres from which it has been prepared .
• polyester fibres require 5-10 times more softening composition than cotton fibres .
• the dosage problem is aggravated .
• the consequen ⁇ ce of these problems is that excessive amounts of rinsing composition are used .
• rinsing composition is not only unsatisfactory for economic reasons but may also have the effect that some fabrics, e. g . cotton goods, become so hydrophoblc that their ability to absorb water is significantly reduced . Furthermore, the use of excessive amounts of rinsing composition causes fabrics which are used in direct contact with the skin , such as underwear, to be soiled more rapidly than with normal dosage of rinsing compo ⁇ sition .
• drying tumblers the laundry is subjected to the influence of a dry, hot stream of air while being mechanically whirled in such a stream of air.
• the major advantages of this drying method are that it is quick, requires only a small space and that the laundry is worked and consequently softened simultaneously with the drying operation .
• the method also have significant drawbacks .
• the method causes the laundry to be substantially worn, a wear which is evidenced by the formation of very substantial amounts of fluff. Therefore, drying tumblers are equipped with fluff filters which serve to prevent the fluff from adhering to the heating elements of the drying tumblers and being ignited .
• the object of the invention is to provide a softening com ⁇ position of the above mentioned type which , apart from softening the fabrics, counteracts carding and fading of the fabrics in sunlight.
• a further object of the invention is to provide a fabric softening composition contained in a liquid absorbent carrier which carrier, if desired , has been impregnated with the softening compo ⁇ sition in the form of a solution containing no organic solvent. According to the invention these and other objects are ob ⁇ tained with a composition which is characterized in that it comprises (a) 20-89.5% by weight of an alkoxylated ⁇ -sitosterol having the ge ⁇ neral formula:
• n is an integer of from 10 to 100, and R is a hydro ⁇ gen atom or a methyl or ethyl group, (b) 10-79.9% by weight of a di(C 12 -C 22 *-al kyl )dimethylammonium chloride or an imidazoline derivative having the general formula:
• R and R each is a saturated or unsaturated hydro-
• additives such as agents for the control of the melting point of the softening composition , agents for controlling the solubility of the composition in water and/or agents for reducing the carding or wear of the fabrics .
• Preferred UV-absorbers are a distyrylbisphenyl derivative having the formula:
• additives mentioned sub item (d) are ⁇ - ⁇ p" -alkylmonoglyceride, sorbitanmonostearate, alkylmonoalkanol amides having the formula:
• R 5 CO NH R 6 OH wherein R is an alkyl group containing 11 to 21 carbon atoms and R is an alkyl group containing from 1 to 6 carbon atoms, and alkoxylated ethylene dia ines.
• composition according to the invention can be used in the form of a solution in a suitable solvent, such as water.
• a suitable solvent such as water.
• the composition preferably constitutes from 5 to 70% by weight of the solution .
• Such a solution is particularly suitable in automatic washing machines in which a given amount of a liquid softening composition is automatically added to the rinsing water.
• the composition according to the invention is preferably used in the form of a fabric softening preparation consist ⁇ ing of a liquid absorbent carrier impregnated with a solution of the softening composition according to the invention .
• a preparation is particularly suitable for use in the above mentioned drying tumb ⁇ lers in which a softening composition is supplied to the laundry while it is being dried , the softening composition being gradually transfer ⁇ red from the impregnated carrier to the laundry during the whirling movement of the laundry.
• a preparation prepared by such an impregnation is pre ⁇ ferably composed in such a manner that the melting point range is above 48°C and below 52°C in dried state in order to ensure that it is uniformly distributed ' over the fabric.
• Such a preparation is preferably manufactured by introduc- Ing the liquid absorbent carrier In the form of single pieces or as a web in a solution , including an aqueous solution , of the above men ⁇ tioned components and by subsequently drying the carrier and optionally cutting it into suitable pieces.
• Another portion of laundry having the same composition as the above mentioned one was also washed at 60°C using the same detergent, and the laundry was dried in a drying tumbler with hot air at 60 C for ⁇ _ hour. Furthermore, an additional portion of laundry having the same com ⁇ position as the above mentioned one was washed in the above men ⁇ tioned manner, but the clean laundry thus obtained was treated with a commercially available rinsing composition containing distearyldi- methylammonium chloride in the manner prescribed by the manufac ⁇ turer before the laundry was dried by hanging .
• Non-treated laundry 20 (10 x 2) 12 (6 x 2)
• the laundry treated with a composition according to the invention has a substantially better feel than laundry treated in the conventional manner with a rinsing composition and subsequently dried by hanging and a better feel than non-treated laundry.
• Non-treated laundry 0.76 g
• the data show that the laundry treated with the composi ⁇ tion according to the invention reflects substantially more light of a wavelength of 440 nm (blue light) than the non-treated laundry and the laundry treated with a rinsing composition . Therefore, the risk of fading of the first mentioned laundry is substantially reduced .
• ethoxylated ⁇ -sitosterol 60 parts by weight contain ⁇ ing 75 moles of ethylene oxide per mole of ⁇ -sitosterol 20 - an al koxylated d ⁇ amine having the formula:
• Amount of fluff Laundry treated with the composition according to the invention ⁇ 0.01 g
• Non-treated laundry 0.71 g
• 20 ethoxylated ⁇ -sitosterol contain- 75 moles of ethylene oxide per mole of ⁇ -sitosterol
• Non-treated laundry 1 .03 g 0.81 g
