Anyone else clock a lot code mid-glam and hear the ISO 22716 alarm in your head? I grabbed a foundation tester marked lot 24H07 and got gel on the first pump, soup on the second; a quick strip check showed a 0.6 pH drift — smiled for the client, swapped the unit, and filed a deviation like it was a punchline.
I carry pH strips in my belt, @OP ; when ‘24H07’ separates, I log temp and snap the label — toss it?
@sam_kline , when it’s ‘gel on first pump,’ I purge twice, warm 10 seconds, invert 3 seconds, then quarantine…

Quick tell I use, @marieT302 : dab a pea on a matte blot card — if the oil halo hits a nickel’s width in 15 seconds, I tag the lot and pull a fresh unit; warming between palms helps a touch, but I don’t trust it after that. You got a halo cutoff you swear by?
IR thermometer check: over 28°C, I quarantine and log. @OP , lights nearby?
@sam_kline +1; for 24H07 I swap the pump; burps mean air ingress, then quarantine.
For ‘0.6 pH drift’, I white-tissue swipe; gray undertone flags oxidation — do you see nozzle browning?
I do a quick 10-second wrist roll on suspect lots and time bubble collapse; if it flattens in under 5 seconds, I pump onto a glass palette and watch for a halo ring within 30 seconds — fast ring = emulsion slip, I pull it. On 24H07, your “gel on the first pump, soup on the second” screams shear break; did the cap torque feel light when you first opened it?
That 24H07 ‘gel then soup’ screams viscosity drift; toothpick drag >5s, I swap — did storage temps swing?
Purge three pumps, then sniff for sharp ethanol; that ‘second pump’ suggests aeration — was the pump head loose, @ritaV2021 ?
Mid-glam I point my pocket IR thermometer at the tester; if it’s >4°C over ambient, that ‘0.6 pH drift’ is probably heat-driven phase creep, so I quarantine and pull a fresh unit. Quick upside-down slow-roll for 15 seconds sometimes rescues it enough to finish the face, but I won’t risk color shift on camera. Did the display sit under a ring light or window all day, @lucas_h1990 ?
