Definitions
- the invention relates to a liquid fabric softening composition with trialkanolamine-based esterquat.
- Fabric softeners are added to the laundry in the last rinse of the machine wash to eliminate the "dry staring" effect of drying laundry Dry rigidity is due to the formation of hydrogen bonds between the cellulosic fibers
- the softener cationic softening compounds penetrate the fiber On the surface of the fiber, they bond with the negative charges, thus weakening the interactions, thus reducing the stiffness of the item of laundry and thus reducing the effort required for ironing and increasing the wearing comfort.
- Liquid fabric softeners are divided into two types: "normal” fabric softeners containing from 1 to 5% by weight of softening compounds and "concentrated” fabric softeners containing from 5 to 80% by weight of softening compounds.
- the acceptance of a fabric softener product by the users is determined not only by the actual performance but also strongly by the viscosity of the product, with medium to high viscosities preferred by the users.
- viscosities in the range of 10 to 400 mPas and for concentrated fabric softeners in the range of 100 to 600 mPas (each determined with a Brookfield viscometer RV DV II + P, spindle 2 at 20 rpm and 20 ° C).
- WO 2004/050812 A1 discloses the use of homo- and / or copolymers as thickeners in fabric softeners.
- the thickeners used often do not themselves show any softening performance and increase the production costs of the softener. Also, not all thickeners are compatible with the ingredients used in fabric softeners.
- An object of this invention was therefore to provide a liquid
- a fabric softening composition containing from 0.5% to 40% by weight, based on the total fabric softening composition, of a softening mixture of trialkanolamine-based ester quat and trialkanolamine-based ester, wherein the liquid fabric softening composition is free of methanol.
- liquid fabric softening compositions comprising a mixture of a trialkanolamine-based esterquat and a trialkanolamine-based ester and which are further free of methanol have higher viscosities than liquid ones
- Fabric softener composition were treated, increased / improved softness.
- a particularly strong increase in viscosity can be obtained in liquid fabric softening compositions in which the amount of fabric softening mixture is from 3 to 18% by weight, based on the total liquid fabric softening composition.
- the invention also relates to the use of a methanol-free, softening mixture of trialkanolamine-based ester quat and trialkanolamine-based ester for increasing the viscosity of a liquid fabric softening composition.
- the invention relates to the use of a methanol-free, softening mixture of trialkanolamine-based esterquat and trialkanolamine-based ester in a liquid
- liquid fabric softening compositions according to the invention are described in detail, inter alia, by way of examples.
- Liquid fabric softening compositions according to the invention comprise a softening mixture which necessarily comprises a trialkanolamine-based esterquat and a trialkanolamine-based ester.
- Understood fatty acid trialkanolamine amine ester salts The preparation of trialkanolamine-based esterquats is usually carried out in two stages: 1) esterification of trialkanolamine with fatty acids for Trialkanolamine-based ester and 2) quaternization of the resulting esters with dimethyl sulfate or chloromethane.
- fatty acids RCOOH are used in which RCO is an aliphatic, saturated and / or unsaturated acyl radical having 6 to 22 carbon atoms.
- Typical examples are caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselinic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidic acid, gadoleic acid, behenic acid and erucic acid, and technical mixtures thereof ,
- fatty acids having 12 to 18 carbon atoms such as partially cured palm and / or tallow fatty acids having an iodine value in the range of 0.5 to 50 are used.
- Particularly preferred tallow fatty acid is used as the fatty acid.
- the esterification takes place in the presence of hypophosphorous acid or its salts and
- the trialkanolamine and the fatty acids are used in a molar ratio of 1: 1, 1 to 1: 2.4, preferably the ratio is in the range 1: 1, 4 to 1: 1, 9.
- the reaction is carried out at temperatures in the range of 120 to 180 ° C.
- Suitable trialkanolamines include, for example, triethanolamine, diethanolpropanolamine and tripropanolamine, with triethanolamine being preferred. Accordingly, it is particularly preferred that the trialkanolamine-based ester is a triethanolamine-based ester.
- alcoholic solution for example in isopropyl alcohol or ethanol.
- the alkylation is carried out with dimethyl sulfate.
- a trialkanolamine-based esterquat particularly preferably obtained by the alkylation is a triethanolamine-based esterquat.
- trialkanolamine-based esterquats in which the quaternizing agent is used equimolar or in a slight excess to the trialkanolamine-based ester, may contain an increased amount of methanol in the raw material.
- the methanol can be detected in the raw material as well as in finished formulations, in particular fabric softeners.
- the content of methanol may be 0.1 to 3 wt .-%.
- finished formulations depending on the amount of raw material used, 50 to 300 ppm of methanol are contained.
- trialkanolamine-based esterquat and trialkanolamine-based ester are obtained, which is free of methanol and, when used in liquid fabric softening compositions, also results in a higher viscosity and increased softening of the composition. Therefore, it is particularly preferred that in the softening mixture obtained after the alkylation, the ratio of trialkanolamine-based ester quat to trialkanolamine-based ester be between 2: 1 and 4: 1. This procedure has the advantage that the resulting mixture can be used directly, without further treatment in the liquid fabric softener compositions and in the alkylation resulting methanol must not be removed later.
- trialkanolamine-based esterquat is a compound of the following formula:
- R 4 is an aliphatic alk (en) yl radical having 6 to 22 carbon atoms with 0, 1, 2 or 3 double bonds and / or optionally with substituents;
- R 5 is OH or O (CO) R 7
- R 6 is, independently of R 5, OH or O (CO) R 8
- R 7 and R 8 are each independently an aliphatic alk (en) yl radical with 1 1 to 21 carbon atoms with 0, 1, 2 or 3 double bonds, m, n and p can each independently of one another have the value 1, 2 or 3 and
- X " can either a halide, methosulfate, methophosphate or phosphate ion and mixtures of
- R 4 , R 7 and R 8 are derived from tallow fatty acid and X " is one
- Preferred trialkanolamine-based esters are N- (2-hydroxyethyl) -N, N-di (tallowacyloxyethyl) amine, N- (2-hydroxyethyl) -N, N-di (palmacyloxyethyl) amine or N- (2-hydroxyethyl) hydroxyethyl) -N, N-di (stearoyloxyethyl) amine.
- Preferred trialkanolamine-based ester quats are correspondingly methyl N- (2-hydroxyethyl) -N, N-di (tallowacyloxyethyl) ammonium methosulfate, methyl N- (2-hydroxyethyl) -N, N-di (palmacyloxyethyl) ammonium methosulfate or methyl N- (2-hydroxyethyl) -N, N-di (stearoyloxyethyl) ammonium methosulfate.
- the trialkanolamine-based ester quat is a mixture of monoester compound, diester compound and triester compound. A mixture of mono-, diester- and triester compounds has the best performance in terms of softness performance and scavenging of anionic residues, such as anionic surfactants, which have undesirably remained in the washing drum from the washing process.
- the liquid fabric softening composition contains the softening mixture
- Trialkanolamine-based esterquat and trialkanolamine-based ester in an amount of 0.5 to 40 wt .-%, more preferably in an amount of 1 to 30 wt .-% and even more preferably in an amount of 2 to 25 wt. %, in each case based on the total liquid
