W094/268562 1 6 2 l ~ 2 I e ~ PCT~S94/04329 MIXING ORDER TO PREPARE AQUEOUS
DETERGENT COMPOSITIONS
Technical field The present invention relates to a process for the manufacture of an aqueous detergent composition. The present invention relates more particularly to a mixing order to prepare such a composition comprising a substantial amount of organic components.
Backqround of the invention Aqueous,- detergent compositions have been described extensively in the art. More specifically it is well known that such compositions may be formulated as solutions comprising water and organic components such as surfactants, perfumes, stabilizers and the like. These organic components are predominantly poorly soluble or even insoluble in water.
Therefore, there is a natural tendency for said compositions to be unclear, i.e. turbid, as said organic components may not be W094/268~6 ^!{~ ~ ~ PCT~S94/04329 ~ 1 62l~ ~ '2 fully dissolved in the aqueous matrix. This becomes even more of a problem as the total proportion of organic components is increased. This phenomenon results in mitigated consumer acceptance. Therefore, the problem the present invention seeks to solve is to avoid turbidity in the compositions finally obtained.
In response to 'his technical problem, applicants have found that by incorporating the different organic components in a specific order during the manufacture of such an aqueous detergent composition, a clear and transparent final composition could be obtained.
It is thus an object of the present invention to obtain an aqueous detergent composition which is clear and transparent.
Applicant's European patent application EP-A-517 996 discloses stable hydrogen peroxide-containing bleaching compositions which are made by mixing together all ingredients except for hydrogen peroxide which is added as a final step in the process. Said application discloses nothing about the aforementioned turbidity problem.
