Abstract
A method for validating a homogenizing valve (1), comprising the steps of:—preparing an emulsion having a hydrophilic phase comprising, in weight percentage on the total weight: from 55% to 74% demineralized water, from 10% to 20% glycerin and from 3% to 4,2% butylene glycol, and a lipophilic phase comprising, in weight percentage on the total weight: from 5.1% to 5.9% squalane, from 7.2% to 8.8% caprylic acid alkyl ester and from 0.665% to 0.735% cetyl alcohol;—subjecting the emulsion to forced passage within the homogenizing valve (1) from a high pressure zone (HP) to a low pressure zone (LP) a plurality of times.
