Definitions
- the present invention relates to supported liquid constituents, as well as their preparation process and the detergent formulas containing said substances.
- liquid or solid detergent compositions for washing natural or synthetic textiles is today widespread. This washing can be carried out in an artisanal way by hand or automatically using machines.
- liquid component of detergent formulas defoamers, perfumes, fabric softeners, nonionic type surfactants.
- the liquid substances supported by the detergent formulas used in the solid detergent compositions must have a certain number of characteristics: - They must be presented in the pulverulent state, so that they can be incorporated into the detergent powder after the various heat treatments; because anti-foaming substances, perfumes, non-ionic substances are generally sensitive to temperature. - They must have an anti-foam function during the entire washing period and at all washing temperatures, that is to say between around 15 and 95 ° C and with all types of detergent formulas. - They must dissolve easily in the detergent medium so as to release the adsorbed liquid component. - The support must be neutral vis-à-vis the liquid substance so as not to destroy it either chemically or by an alkalinity problem.
- the support must absorb the liquid substance, it must also protect it from external elements such as the aggressive agents of the detergent formula, water which, for example, tends to hydrolyze the antifoam compound. This protection must sometimes be effective for relatively long periods.
- the support must not be of the phosphate type insofar as currently, environmental protection wants to limit the use of this type of compound in detergent compositions.
- the present invention has made it possible to achieve the characteristics described above. It relates to supported liquid constituents for washing formula characterized in that they consist of sodium sulfate adsorbing said liquid constituent which is protected by silica.
- the liquid constituent on the support of the present invention preferably has the following constitution expressed by weight: - sodium sulfate: 83-90% - liquid constituent: 8-12% - precipitated silica: 1- 4%
- the sodium sulphate used is preferably a sulphate obtained after a calcination step at a temperature between 250 ° C and 400 ° C in an oxidizing atmosphere and in a stirred medium, which has the advantage of increasing the porosity of the support.
- the liquid agent adsorbed on this support is constituted, as specified above, but not limited to, by an agent anti-foam, a fragrance, a non-ionic surfactant ...
- an antifoaming agent having a composition as defined in patent EP 210,114.
- the silica used is a precipitated amorphous silica whose particle size is less than 0.075 mm.
- precipitated silica sold by RHONE-POULENC under the brand TIXOSIL 38 A.
- the process for the preparation of the liquid constituents on a support of the present invention consists in mixing the antifoaming composition with the sodium sulphate and then in introducing the amorphous silica into a powder mixer.
- an amount of supported defoaming constituents is used such that the weight ratio of defoaming constituent supported to the detergent formula is between 1.5 and 3% and preferably about 2%.
- the mixtures were made using a 5 liter LODIGE laboratory mixer.
- the Anti-foam Compound has the following composition: - 85 to 95% silicone oil, dimethylpolysiloxane, viscosity of around 1000 mPa / s at 25 ° C, - 5 to 15% precipitated silica having a specific surface of 300 m2 / g.
- This mixture was treated for approximately 8 hours at 150 ° C., homogenized and ground in the liquid phase.
- the addition rate is uniform and equal to 0.2% of active ingredients, or 2% of the premix powders described above.
- compositions are then subjected to a foam level test in a MIELE 421 S washing machine with a graduated front window, which makes it possible to visually monitor the anti-foam effect during a complete washing cycle, the temperature changes from ambient (network water temperature) to 95 ° C.
- the "washing" is done with a load of linen of 3 kg to simulate the mechanical effects.
- H max the maximum foam height reached (0 - 22cm). The best results are found at foam levels of 12 - 14 cm.
