Definitions

• the invention relates to alkoxylated natural oils and fats as nitrogen-free active ingredient components in fabric softener formulations and their use therefor.
• the alkoxylated natural oils and fats can be used both alone and in admixture with customary nitrogen-containing active components with and without the addition of dispersants, emulsifiers and / or solubilizers.
• N-distearyl-N, N-dimethylammonium chloride DSDMAC
• substitutes such as Imidazoline derivatives (see US Pat. No. 4,762,685, EP-A 0 199 383), quaternized fatty acid esters of triethanolamine (so-called esterquats, see US Pat. No. 4,830,771) or 2,3-dihydroxypropyl-1-trimethylammonium salt.
• Derivatives (DE-OS 27 28 841) replaced.
• the invention is therefore based on the object of finding nitrogen-free active ingredient components which are an alternative to sole use nitrogen-containing fabric softener active ingredient components or in combination with these, if appropriate after appropriate emulsification or dispersion and / or addition of solubilizers. They should not only be miscible and compatible with them, but should also act synergistically if possible, or else have softening properties on their own.
• the object is achieved by the use of alkoxylated natural oils and fats as nitrogen-free active ingredient.
• the oils and fats which can be used as starting material according to the invention basically include all triglycerides and their mixtures with free fatty acids, mono- and / or diglycerides.
• the alkoxylation can be carried out in accordance with DE-OS 36 17 657 and DE-OS 38 26 179.
• the invention therefore relates to a nitrogen-free active ingredient component for fabric softener formulations consisting of alkoxylated natural fats, oils and their mixtures with free fatty acids, mono- and / or diglycerides.
• Another object of the invention is the use of alkoxylated natural fats, oils and their mixtures with free fatty acids, mono- and / or diglycerides alone as a nitrogen-free fabric softener active ingredient or in mixtures with nitrogen-containing cationic active fabric softener ingredients and optionally dispersants, emulsifiers and / or solubilizers.
• the proportion of the alkoxylated natural fats, oils and their mixtures with free fatty acids, mono- and / or diglycerides as fabric softener active ingredient is 1 to 100%, preferably 20 to 80%, of the total amount of fabric softener active ingredient.
• epoxides are mentioned as examples for the alkoxylation: Ethylene oxide, propylene oxide, butylene oxide, 2-methyl-2-butene oxide, 3,3-dimethyl-1-butene oxide, C6-C24 epoxides, styrene oxide, 1,2-epoxy butadiene, 1,2-epoxy cyclohexene, and glycide esters and ethers. If more than one epoxy is used, these can be reacted with the fatty substances either in succession or simultaneously.
• the proportion of the cationic nitrogen-containing fabric softener active ingredients and their mixtures with one another as a fabric softener active ingredient component is 0 to 99%, preferably 20 to 80%, based on the total amount of fabric softener active ingredient.
• cationic nitrogen-containing fabric softener active ingredient components are: N, N-distearyl-N, N-dimethylammonium salts, imidazoline derivatives (quaternized or protonated), quaternized fatty acid esters of triethanolamine and 2,3-dihydroxypropyl-1-trimethylammonium salt derivatives.
• Both the alkoxylated natural oils and fats alone and their mixtures with the cationic nitrogen-containing fabric softener active ingredient components can optionally be used with dispersants, emulsifiers and / or solubilizers to further increase the activity.
• the ratio of dispersants, emulsifiers and / or solubilizers or mixtures thereof to the fabric softener active ingredient components mentioned is 0 to 10: 1.
• the softening effect of the alkoxylated fats, oils or their mixtures with free fatty acids and / or mono- and / or diglycerides or their blends with commercially available fabric softener active ingredients was determined as follows: A batch of 72 terry towels (44 cm x 30 cm, approx. 60 g, from WFK-Testgewebe GmbH), even if not all 72 wipes were used (for reasons of uniform wear), were machine washed, rinsed and spun once with 100 g of a commercially available full detergent (PERSIL, Henkel) at 95 ° C. This was followed by a wash cycle at 95 ° C. without detergent, including a rinse cycle and a brief spin-on, so that clean, moist cloths containing about 2.5 times their dry weight of water could be removed for manual fabric softening.
• PERSIL commercially available full detergent
• test subjects were each presented with 3 wipes in encrypted form according to the test plan according to Table A (so-called triangular test).
• the task for the examiner was to find out the differently treated cloth after sensory assessment.
• the result is expressed with the help of 3 numbers: The 1st number indicates the number of examiners who found the wipes treated with the standard to be softer or those with the test substance as harder. The second number indicates the number of examiners who found the wipes treated with the standard to be harder or those with the test substance as softer. The 3rd number finally indicates the number of examiners who are due the slight sensory differences of the wipes treated with the test substance or the standard could not determine the wipe treated differently or did not give the correct answer.
• Wipes treated with 0.2-0.5 g of the product from the reaction of skin fat with 15% by weight of propylene oxide per liter of washing liquor were tested in comparison with wipes which had not been treated with a fabric softener.
• the result is summarized in Table 2.
• test substance With the help of the test substance, it is even possible to significantly improve the softening properties if 1 40 to 60% by weight of the test substance is added (see sample numbers 25 and 26). If a test substance / 1 - (4: 1) mixture used, the softening properties are the same as those of pure 1 (see sample no. 27).
• test substance can be mixed with 2 in all the mixtures examined, the softness of the treated wipes not deteriorating, in some cases even being improved (see sample numbers 34-36).
• test substance can be evaluated in all ratios with 3 mix, keeping the soft feel of the treated wipes the same.
• Table 11 shows the determined rise heights of the terry fabrics treated with samples 1-47 from examples 1-10. These are mean values from duplicate determinations.
• the rising heights of the O-sample should be treated after 5 minutes: 10.2 cm, after 65 minutes: 18.5 cm ) with those of the sample no. 13 or 18 (treated with pure ester quat, after 5 min: 6.9 cm, after 65 min: 12.2 cm), 23 or 28 (treated with pure 1 , after 5 min: 4.8 cm, after 65 min.8.6 cm), 33 (treated with pure 2 , after 5 min: 6.0 cm, after 65 min: 10.0 cm) and 38 or 43 (treated with pure 3 , after 5 min .: 3.9 cm, after 65 min .: 5.3 cm) can be compared.
• PERSIL commercial heavy-duty detergent
• alkoxylated natural fats, oils and their mixtures with free fatty acids, mono- and / or diglycerides are used in a mixture with the above-mentioned cation-active nitrogen-containing fabric softener active ingredients or their ready-to-use formulations, it can be seen after considering the rise heights after 5 and 65 min. the following: None of the mixtures recommended in Examples 1-10 brings about a reduction in the rise heights in comparison to the corresponding cation-active substances. There is often a significant increase.
