Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] Technical Field The present invention relates to liquid or granular composition for use in laundry applications. Here, the composition comprises certain dye-retaining polymers having a positive net charge. Standardized test means are provided for measuring the dye maintenance parameters of any given polymer. Compositions comprising the dye-retaining polymers of the present invention have a beneficial appearance and integrity effect on fabrics and fabrics washed in a washing solution made from such compositions.

[0002] inevitably in the background and worn was using a cloth and fabrics such as clothing and clothing performed alternately cycle of washing, appearance and integrity of the fabric and textile products, which was used as such washing It is, of course, well-known that this is adversely affected. Fabrics and fabrics easily age with time and over time. Washing fabrics and fabrics is necessary to remove dirt and stains that have accumulated in and on them during normal use. However, if the washing operation itself is repeated many times, such deterioration of the integrity and appearance of the fabric or the woven fabric may be noticeable or contribute to the deterioration.

[0003] Deterioration of the integrity and appearance of fabrics is evident in several ways. From the woven or knitted fabric / textile fabric, the mechanical action of washing removes short fibers. These detached fibers are easily visible on the surface of the fabric and can form lint, fluff, or "pills" that can detract from the appearance of the fabric. Also, repeated washing of fabrics and fabrics, especially with laundry products that contain bleach, results in a loss of dye from the fabric or fabric, resulting in reduced color purity and, in many cases, hue and color. Changes can result in a tinted, obscured appearance.

[0004] In view of the above, it is important to reduce the tendency of the laundry product itself to combine with the fibers of the fabric or fabric washed with the laundry product, thereby deteriorating the appearance of the washed fabric / fabric. Obviously, there is a continuing need to identify substances that could be added to the laundry product, or to a minimum. Of course, any such additive material for a detergent product can have a beneficial effect on the appearance and integrity of the fabric without unduly hindering the ability of the laundry product to perform its intended function. Must be something. The present invention is directed to the use of the dye-retaining polymer in laundering applications made in this desired manner and to a test means for measuring the dye-retaining parameters of any given polymer.

The level of unsaturation contained within tallow, canola, or other fatty acyl unit chains can be measured by the iodine value (IV) of the corresponding fatty acid. In the case of the present invention, the iodine value should preferably be in the range from 5 to 100. I
The compound is classified into two types depending on whether V is 25 or less or 25 or more.

In fact, the following formula obtained from tallow fatty acid

Embedded image Is greater than about 30/70, preferably greater than about 50/50, more preferably greater than about 70/30 when the iodine value is 5-25, preferably 15-20. It has been found that the / trans isomer weight ratio provides the optimum enrichment.

For this type of compound made from tallow fatty acids having an iodine value of 25 or more,
The ratio of the cis isomer to the lance isomer should be used unless very high concentrations are required.
Turned out to be less important. In a further preferred embodiment of the present invention, R ¹ And DEQA having an average iodine value of about 45.

R ¹ units suitable for use in the isotropic liquids of the present invention are the iodine values of the parent fatty acid (
IV) is preferably from about 10, more preferably from about 50, most preferably from about 70 to a value of about 140, preferably up to about 130, more preferably about 1
Up to 15 can be further characterized.
However, depending on the embodiment of the invention they have chosen to practice, the formulators may wish to add a certain amount of fatty acyl units having an iodine value outside the above range. For example, a "hardened stock" (iodine value of about 10 or less) may be combined with a fatty acyl mixture source to adjust the properties of the final softener active.

Preferred sources of fatty acyl units, especially fatty acyl units having “Guerbet branches”, which are branches, for example methyl units, ethyl units etc. substituted along the primary alkyl chain, have been obtained by synthesis. Sources of fatty acyl units are also suitable. For example, formulators, the "naturally impossible is" position, for example, one have a methyl branch on the third carbon of the C ₁₇ chain, one or may wish to add a more fatty acyl units might exist. As used herein, the term "impossible in nature" means that "in ordinary fats and oils that serve as a source of the triglyceride sources described herein, they are significant (about 0.1 % Of acyl units not found in amounts). If the desired branched fatty acyl units are not available from readily available natural sources, synthetic fatty acids can be combined with other synthetic substances or with other natural triglyceride-derived acyl unit sources. it can.

[0064] illustrate the compositions and methods of the present invention by the following examples examples, these examples are either to limit the scope of the present invention necessarily, otherwise not limiting.

Example I Dye Retention Parameters Test To evaluate a dye retention polymer, a 10 ppm aqueous solution of the dye retention polymer is prepared. 800 ml of this solution is placed in a 1000 ml beaker. 8g ±
A swatch of 50 mg of fabric C110 (C110 is a fabric of poplin dyed with direct black 112 and supplied by Empirical Manufacturing Company of Cincinnati, Ohio) is completely spilled over the liquid. Into the solution as described. The solution is gently stirred with a magnetic stirrer for 120 minutes. Some of the dye slowly oozes into the water from the fabric. After 120 minutes, remove an aliquot of the liquid, place it in a 5 cm path length cell, and use a Hulett-Packard Model 8453 Ultraviolet to Visible Spectrophotometer, a general method used by the manufacturer to use this device. The absorbance at a wavelength of 600 nm is measured according to the following instructions. This absorbance is called Abs _polymer .

The Abs _water is determined using the procedure outlined above and repeating this procedure using only distilled water without the addition of a dye-retaining polymer. The dye maintenance parameter ("DMP") is defined as (Abs _polymer- Abs _water ).

EXAMPLE II Calculation of Average Charge Per Molecule There are many methods known to those skilled in the art of analytical technology to calculate the charge density of a polymeric material. Is as follows.
Specifically, the charge density of a molecule whose chemical structure is known is determined by standard acid-base titration or potentiometric titration for obtaining a charge-to-mass ratio. The charge density can then be converted to an average charge per molecule by measuring the average molecular weight of the material and dividing the charge density by this average molecular weight to determine the average number of positive charges per molecule.

For low molecular weight substances, the molecular weight is measured by standard techniques such as mass spectrometry. In the case of a high molecular substance, the molecular weight is measured by gel permeation chromatography. These methods are described in "Instrumental" by Willard, Merritt, Dean, Settle.
Methods of Analysis ”in textbooks of analysis.
