Air-return selective sealing valve: LorealRecent Research Landscape

Product oxidation and inconsistent dosing during automatic loading increase waste and compromise formula integrity. These innovations utilize internal bladder and valve geometries to maintain airtight seals and precise volumetric control.

What technical problems is Loreal addressing in Air-return selective sealing valve?

Inaccurate cosmetic product dosing

(46)evidences

Improper alignment and indexing of packaging components lead to inconsistent product delivery and leakage. Correcting these mechanical misalignments ensures precise dosage and prevents fluid contamination.

Unintended aerosol propellant leakage

(12)evidences

Atmospheric air ingress during dispensing cycles degrades sensitive cosmetic formulas. Preventing backflow ensures product purity and extends shelf life without preservatives.
