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.

Abstract: A homogenizing apparatus (1) comprising: —an inlet (2) for receiving a pressurized fluid, possibly also containing solid particles; —a zone wherein homogenization of the fluid takes place; —an outlet (10) for the fluid at a lower pressure with respect to the inlet pressure, wherein, in the homogenization zone, the fluid passes from a zone having a larger diameter (or volume) to a zone having a smaller diameter (or volume), the homogenization zone comprising an interacting element (9) shared by a first stage (equipped with a first deflector plug (6)) and a second stage suitable for creating back pressure (equipped with a second deflector plug (12)), where the deflector plugs (6 and 12) operate with the interacting element (9) they share, generating an increase in the shear rate within the first stage. The invention also concerns a homogenization process.
