Cosmetic factory QC lab — pH meters, viscometers, preservatives testing, microbiology, and raw material analysis products.
QC in Cosmetics Manufacturing
Lahore and Karachi host a growing cosmetics and personal care manufacturing sector. Every batch requires release testing — pH, viscosity, microbial limits, and stability — before market distribution.
Regulatory Context
Products must meet safety expectations under DRAP and consumer protection norms. In-house or third-party labs need validated methods and traceable reagents.
Cosmetic Lab Essentials
- pH testing: Benchtop pH meter, calibration buffers, electrodes for creams
- Viscosity: Brookfield-type viscometer, spindles for lotions and gels
- Microbiology: TPC, yeast & mould, P. aeruginosa, S. aureus on SDA and TSA
- Chemicals: Reference oils, surfactant standards, and viscosity calibration supplies
- Packaging compatibility: Extractables testing solvents (model dependent)
- Stability: Oven 40°C/75% RH chamber supplies, sample jars
Raw Material Incoming QC
Test glycerin, propylene glycol, and botanical extracts for identity and purity before batching — IR reference standards and moisture testing are common starting points.
