Definitions

  • the present invention relates to the use as a fabric damage inhibitor or fibre protector of a fabric softening composition comprising a biodegradable quaternary ammonium material.
  • Rinse added fabric softening compositions are well known. Typically such compositions contain a water insoluble quaternary ammonium fabric softening material dispersed in water at a level of quaternary ammonium material up to 7% by weight in which case the compositions are considered dilute, or at levels from 7% to 50% in which case the compositions are considered concentrates.
  • fabric softening compositions desirably have other benefits. Such other benefits are particularly important for consumers who believe that the use of fabric softening compositions causes damage to the environment and that the damage outweighs the softening benefit obtained.
  • a typical wash will include some fabric containing cotton fibres. Abrasion of cotton fibres under wet conditions results in cotton fibre fibrillation whereby the cotton fibres are gradually broken down into their component fibrils and into fibrillar sheets. Such fibrillation is an important mechanism by which fabrics are damaged during wash processes. Damaged fabrics scatter light to a greater extent than undamaged fabrics and the scattering causes dulling of fabric colours. Ultimately the damage will result in mechanical disintegration of the fibre and the consequent failure of cotton garments. The main causes of fibrillation have been found to be swelling of the fibres when wet and friction. Both wet and dry friction cause damage.
  • a fabric damage inhibitor or reducer of a fabric softening composition comprising a quaternary ammonium material having two C12 ⁇ 28 alkyl or alkenyl groups connected via an ester link to the quaternary nitrogen atom.
  • inhibitor includes a component which confers protective care or protection on a fibre.
  • it encompasses those materials which reduce the damage to the fibre which would otherwise occur during the course of wearing and washing a garment.
  • composition is a liquid comprising an aqueous base.
  • a preferred type of ester-linked quaternary ammonium material for use in the compositions according to the invention is represented by the formula: wherein each R1 group is independently selected from C1 ⁇ 4 alkyl, alkenyl or hydroxyalkyl groups; and wherein each R2 group is independently selected from C8 ⁇ 28 alkyl or alkenyl groups; and n is an integer from 0 to 5.
  • the level of ester linked quaternary ammonium compound is at least 1% by weight of the composition, more preferably more than 3% by weight of the composition; especially interesting are concentrated compositions which comprise more than 7% of ester-linked quaternary ammonium compound.
  • the level of ester-linked quaternary ammonium compound is preferably is between 1% and 80% by weight, more preferably 3% to 50%, most preferably 8% to 50%.
  • the softening composition may be stabilised at low temperatures by the addition of nonionic stabilisers.
  • Suitable nonionic stabilisers which can be used include the condensation products of C8 - C22 primary linear alcohols with 10 to 20 moles of ethylene oxide.
  • the alcohols may be saturated or unsaturated.
  • Genapol T-110, Genapol T-150, Genapol T-200, Genapol C-200 all ex Hoeschst AG, Lutensol AT18 ex BASF, Genapol 0-100 and Genapol 0-150 ex Hoechst, or fatty alcohols for example Laurex CS, ex Albright and Wilson or Adol 340 ex Sherex.
  • the nonionic stabiliser has an HLB of between 10 and 20, more preferably between 12 and 20.
  • the level of nonionic stabiliser is within the range from 0.1 to 10% by weight, more preferably from 0.5 to 5% by weight, most preferably from 1 to 4% by weight.
  • the mole ratio of the quaternary ammonium compound to the nonionic stabilising agent is within the range from 40:1 to about 1:1, preferably within the range from 18:1 to about 3:1.
  • the composition can also contain fatty acids for example C8 - C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • fatty acids for example C8 - C24 alkyl or alkenyl monocarboxylic acids or polymers thereof.
  • saturated fatty acids are used, in particular, hardened tallow C16-C18 fatty acids.
  • the fatty acid is non-saponified, more preferably the fatty acid is free; for example oleic acid, lauric acid or tallow fatty acid.
  • the level of fatty acid material is preferably more than 0.1% by weight, more preferably more than 0.2% by weight. Especially preferred are concentrates comprising from 0.5 to 20% by weight of fatty acid, more preferably 1% to 10% by weight.
  • the weight ratio of quaternary ammonium material to fatty acid material is preferably from 10:1 to 1:10.
  • compositions of the invention preferably have a pH of more than 2, more preferably between 2 and 5.
  • the composition can also contain one or more optional ingredients, selected from non-aqueous solvents, pH buffering agents, perfumes, perfume carriers, fluorescers, colorants, hydrotropes, anti-foaming agents, anti-redeposition agents, enzymes, freeze-thaw stabilisers, optical brightening agents, opacifiers, anti-shrinking agents, anti-wrinkle agents, anti-spotting agents, germicides, fungicides, anti-oxidants, anti-corrosion agents, drape imparting agents, antistatic agents and ironing aids.
  • optional ingredients selected from non-aqueous solvents, pH buffering agents, perfumes, perfume carriers, fluorescers, colorants, hydrotropes, anti-foaming agents, anti-redeposition agents, enzymes, freeze-thaw stabilisers, optical brightening agents, opacifiers, anti-shrinking agents, anti-wrinkle agents, anti-spotting agents, germicides, fungicides, anti-oxidants, anti-corrosion agents
  • composition may also contain nonionic fabric softening agents such as lanolin and derivatives thereof.
  • the figure shows a yarn on yarn abrasion tester with a test yarn 1 comprising fibres.
  • the two ends of the yarn are attached to metal links 2 and 3.
  • Metal link 2 joins the yarn to a cord 4 which passes over a first upper yarn guide pulley 4A and is attached to a tensioning weight 5. Typically a 20g tensioning weight is used.
  • the other end of the yarn is attached to a second cord 6 by the metal link 3.
  • the yarn is twisted about itself in the test region 7 and is weighed down by passing the yarn around a lower yarn guide pulley 8.
  • the second cord 6 passes over a second upper yarn guide pulley 9 and is attached to an electrically driven reciprocating means 10.
  • a beaker 11 is provided for containing water or aqueous media used to test the yarn in wet conditions.
  • the test method consists of attaching the yarn to be tested to one of the metal links, passing the yarn around the lower yarn guide pulley 9 and then twisting the yarn around itself a predetermined number of times to form the test region 7, before attaching it to the other metal link. If required, the beaker is filled with an aqueous test medium. The reciprocating means is then switched on. A record is kept of the number of oscillations of the reciprocating means before failure. In each of the following examples the test was repeated a number of times and very high or low results discarded before a statistical analysis was made of the remaining data.
  • the yarns were then rinsed. Some yarns were rinsed in water as a control and others were rinsed in fabric softening compositionsr. Two fabric softening compositions were used, one containing the cationic quaternary ammonium Arquad 2HT as the quaternary ammonium material and the other containing HT TMAPC as the biodegradable cationic quaternary ammonium material.
  • compositions of the two fabric softening compositions were as follows:
  • compositions were used at recommended concentrations in cold water. After rinsing, the yarns were allowed to dry for 24 hours at room temperature. They were then individually abraided on the yarn on yarn abrasion tester. Abrasion tests were carried out dry and in washing powder solution. All tests were carried out using tap water at room temperature.
  • Table 1 shows the mean number of cycles before 24 samples of yarn failed in a dry abrasion test. TABLE 1 Treatment Number of cycles to failure Water 964 DHTDMAC 1503 HT TMAPC 2407
  • Example 1 was repeated with the yarn immersed in a solution of "New Persil automatic". This simulated the effect of a faric softening composition on fibre damage caused during the next wash. The variation in the number of cycles until breakage in this example was found to be less than that for example 1. This means that smaller differences in the mean number of cycles to failure become statistically significant. The results are given in table 2. TABLE 2 Treatment Number of cycles to failure Water 1487 DHTDMAC 1533 HT TMAC 1615
