lines, l'eau dure provoque l'apparition de dépôts de carbonate de calcium qui ont un effet néfaste sur le toucher des articles lavés et peuvent perturber le fonctionnement du lave-linge par la formation d'une croûte dure sur les é.éments de chauffage et sur les autres parties. On a essayé de résoudre ce problème en ajoutant des substances acides pendant le cycle de lavage, mais il est difficile de choisir le bon moment pour une telle addition et il est gênant, spécialement pour la ménagère, de devoir interrompre le cycle de lines, hard water causes the appearance of calcium carbonate deposits which have a detrimental effect on the touch of the washed articles and can disturb the functioning of the washing machine by the formation of a hard crust on the elements. heating and on the other parts. We have tried to solve this problem by adding acidic substances during the washing cycle, but it is difficult to choose the right time for such an addition and it is inconvenient, especially for the housewife, to have to interrupt the washing cycle.

De tels essais relèvent cependant de la routine et sont à la portée de l'homme de métier. Généralement, des quantités de 1 à 4 g de générateur d'acide par litre de bain de lavage acid generator necessary to obtain the desired final pH; this will depend on various factors, including alkalinity, amount and buffering capacity of the detergent composition used. However, such tests are routine and are within the reach of the skilled person. Generally 1 to 4 g of acid generator per liter of washing bath

La composition détergente utilisée peut être l'une quelconque des lessives sous forme liquide ou de poudre, qui peuvent contenir des composants habituels, par exemple des builders, des agents tensio-actifs, des agents de blanchiment, des véhicules, des agents adoucissants, des agents anti-microbiens, des enzymes, des azurants optiques et des parfums. Le procédé de l'invention est particulièrement avantageux lorsque la composition détergente contient un agent adoucissant usuel. Le générateur d'acide utilisé peut être liquide ou solide. S'il s'agit d'un produit solide qui The detergent composition used can be any of the detergents in liquid or powder form, which may contain common components, for example builders, surfactants, bleaches, vehicles, softeners, anti-microbial agents, enzymes, optical brighteners and perfumes. The process of the invention is particularly advantageous when the detergent composition contains a usual softening agent. The acid generator used can be liquid or solid. If it is a solid product that

copique, comme la lactone de l'acide polyhydroxy- copic, such as polyhydroxy acid lactone-

Selon un autre aspect, l'invention concerne donc un produit de lavage sous forme de poudre contenant de 5 à 35 % en poids d'un générateur d'acide sous forme d'une poudre non hygroscopique. Un tel acrylic, it can advantageously be mixed with the detergent composition which is in the form of powder. According to another aspect, the invention therefore relates to a washing product in powder form containing from 5 to 35% by weight of an acid generator in the form of a non-hygroscopic powder. Such

Le lavage selon l'invention des textiles sales en présence d'un générateur d'acide, peut être Washing dirty textiles according to the invention in the presence of an acid generator can be
effectué selon les méthodes classiques et aux tempé- carried out according to conventional methods and at temperatures
ratures habituelles. Le procédé est approprié pour le lavage domestique ou industriel. Après le cycle de lavage, les articles sont rincés selon les méthodes habituelles. L'abaissement du pH pendant le cycle de lavage réduit les dépôts de calcium et confère un toucher plus doux aux articles lavés. L'effet sur le toucher des articles est particulièrement prononcé lorsqu'on utilise des compositions détergentes usual erasures. The process is suitable for domestic or industrial washing. After the washing cycle, the articles are rinsed according to the usual methods. Lowering the pH during the wash cycle reduces calcium deposits and gives a softer feel to the items being washed. The effect on the touch of the articles is particularly pronounced when using detergent compositions

A washing cycle of 60 is chosen and 8 g / l of a usual commercial washing powder, containing a fabric softener, and 1 g / l of the reaction product of 1.7 mole of ethylene oxide are added. on 1 mole of 85% formic acid. When the wash cycle at 600 is finished after 23 minutes, we
rince et on sèche les articles.rinse and dry items.
Au début du cycle de lavage, immédiatement après l'addition du générateur d'acide, le pH.est de At the start of the wash cycle, immediately after the addition of the acid generator, the pH is
9,3 et de 8,8 à la fin du cycle.9.3 and 8.8 at the end of the cycle.
Lorsqu'on utilise 2 g/l de générateur d'acide, le pH final est de 7,6 et lorsqu'on utilise When using 2 g / l of acid generator, the final pH is 7.6 and when using
4 g/l, on atteint un pH final de 6,5. 4 g / l, a final pH of 6.5 is reached.
On obtient un linge propre avec un toucher doux. Lorsque le cycle de lavage est effectué sans addition de générateur d'acide, les valeurs initiales You get a clean cloth with a soft touch. When the washing cycle is carried out without adding an acid generator, the initial values
et finales du pH sont.espectivement de 10 et de 9,6. and final pH values are 10 and 9.6 respectively.
Exemple 2Example 2
On procède de manière analogue à celle décrite à l'exemple 1 mais on utilise le lactate d'éthylèneglycol comme générateur d'acide. Les valeurs finales du pH sont les suivantes: pour 1 g/l, 9,2; pour The procedure is analogous to that described in Example 1, but ethylene glycol lactate is used as the acid generator. The final pH values are as follows: for 1 g / l, 9.2; for
2 g/l, 8,6; pour 4 g/l, 8,1.2 g / l, 8.6; for 4 g / l, 8.1.
Exemple 3Example 3
On procède comme décrit à l'exemple 1 mais on utilise, comme générateur d'acide, la lactone de The procedure is as described in Example 1, but the lactone of
l'acide poly-a-hydroxyacrylique sous forme de poudre. poly-a-hydroxyacrylic acid in powder form.
0,5 g/l donne un pH final de 9,2, 1 g/l, un pH final de 0.5 g / l gives a final pH of 9.2, 1 g / l, a final pH of
8,7 et 2 g/l un pH final de 7,7.8.7 and 2 g / l a final pH of 7.7.
