Definitions

• Quaternized fatty acid triethanolamine ester salts which belong to the group of esterquats, are cationic surfactants which are readily taken up by synthetic and natural fibers and which provide them with substantivity and a pleasant soft feel. Accordingly, aqueous dispersions of these compounds are used as fabric softeners and as hair conditioners. They are generally produced from fatty acids which are partly esterified with triethanolamine in the presence of hypophosphorous acid and then quaternized with alkyl halides or dialkyl sulfates, preferably methyl chloride or dimethyl sulfate, in a solution of lower alcohols or polyols. A molar ratio of triethanolamine to fatty acid of 1:1.2 to 1:2.2 is generally described in the literature, a ratio of 1:1.5 to 1:1.9 being preferred for performance reasons.
• the problem addressed by the present invention was to provide new water-containing preparations based on quaternized fatty acid triethanolamine ester salts which would have pearlescent properties without the addition of waxes and which would match known products in their performance properties.
• the present invention relates to pearlescent water-containing preparations which can be obtained by: (a) reacting triethanolamine and C 12-22 fatty acids in a molar ratio of 1:1.3 to 1:1.4, (b) subsequently quaternizing the esterification products in known manner and (c) dispersing the quaternization products in water.
• esterquats which have pearlescent properties in the form of aqueous dispersions can be produced by controlling the degree of esterification and the fatty acid, so that there is no need to use typical pearlizing waxes, for example of the glycol fatty acid ester type.
• the invention includes the observation that the molar ratio between triethanolamine and the fatty acids selected is the critical parameter: too low a ratio would lead to low pearlescence and, in particular, to unsatisfactory performance properties whereas, if the ratio is too high, no pearlescent effect at all is observed.
• the present invention also relates to a process for the production of pearlescent water-containing preparations, in which (a) triethanolamine and C 12-22 fatty acids are reacted in a molar ratio of 1:1.3 to 1:1.4, (b) the esterification products are then quaternized in known manner and (c) the quaternization products are dispersed in water.
• the preparations preferably contain 1 to 20% by weight, preferably 3 to 15% by weight and more particularly 5 to 10% by weight of free C 12-22 fatty acids.
• the esterquats may be produced both from fatty acids and from the corresponding triglycerides.
• the condensation of the alkanolamines with the fatty acids may also be carried out in the presence of defined quantities of dicarboxylic acids such as, for example, oxalic acid, malonic acid, succinic acid, maleic acid, fumaric acid, glutaric acid, adipic acid, sorbic acid, pimelic acid, azelaic acid, sebacic acid and/or dodecanedioic acid. This results in a partly oligomeric structure of the esterquats.
• the quaternized fatty acid triethanolamine ester salts according to the invention are produced in the presence of lower aliphatic alcohols or polyols which are added to the intermediate products before the quaternization.
• C 1-4 alcohols and C 2-10 alkylene glycols, especially isopropyl alcohol or propylene glycol, are suitable for this purpose. Their production is described, for example, in DE 19738645 C1 (Cognis).
• the quaternization generally gives 60 to 95% by weight and preferably 75 to 85% by weight preparations of the quaternized fatty acid triethanolamine ester salts in the lower alcohols or polyols which are then diluted with water to a solids concentration of 5 to 40% by weight and preferably 10 to 30% by weight and show pearlescence even in this concentration range.
• the present invention also relates to the use of the new pearlescent water-containing preparations for the production of softeners for synthetic and/or natural fibers in which they may be present in quantities of 10 to 100% by weight, based on the final preparation.
• the preparations themselves may be used as softeners, although they may also be further diluted with water and/or other typical auxiliaries and additives may be incorporated. This is particularly the case when the preparations are to be used as hair conditioners. So far as the additives in question are concerned, reference is again made to the above-cited DE 19738645 C1.
• 1 kg terry towelling was washed at 60° C. in a standard domestic washing machine of the Miele type and a measuring capful of the softener dispersions was added to the liquor.
• the results are set out in Table 1. Examples 1 to 3 correspond to the invention, Examples C1 to C3 are intended for comparison.
