Patent

CA 2719883

The invention provides a method of manufacturing a stable aldehyde-surfactant complex solution wherein at least one aldehyde is added to a surfactant in a first aliquot of water, at a temperature of between 40°C to 50°C, the aldehyde is allowed to interact with the surfactant or detergent, in a complexing reaction, for at least 15 minutes whilst maintaining the temperature between 40°C to 50°C to produce an aldehyde-surfactant complex solution, and a second aliquot of water is added after at least 15 minutes to cool the aldehyde-surfactant complex solution to below 40°C to stop the complexing reaction.

Cette invention concerne un procédé permettant de fabriquer une solution complexe aldéhyde-tensioactif stable, selon lequel au moins un aldéhyde est ajouté à un tensioactif dans une première aliquote d'eau à une température comprise entre 40°C et 50°C, à permettre l'interaction de l'aldéhyde avec le tensioactif ou le détergent, dans une réaction complexante, pendant au moins 15 minutes tout en maintenant la température entre 40 et 50°C de manière à produire une solution complexe aldéhyde-tensioactif, puis une seconde aliquote d'eau est ajoutée après au moins 15 minutes afin de refroidir ladite solution à une température inférieure à 40°C de manière à stopper la réaction complexante.
