Beauty / Cosmetics Testing

PTL’s analytical staff has years of experience designing test methods and performing analysis for cosmetic, skin care, fragrance and personal cosmetics_particle_testing hygiene samples. Whether your company needs a third party verification, routine QC confirmation, stability studies or one time testing, PTL will create a project to meet your needs. Applications include the size and shape of cosmetic enhancers (glitter particles for example) in a final product, droplet size from spray nozzles/atomizers and particle size of emulsion particles comprising creams/lotions. In addition, the particle size of powdered cosmetics is of tremendous importance in how they flow, cover and can directly affect their appearance as well as the user’s skin.

PTL's depth of experience with cosmetics sample testing and analysis is what sets us apart as an expert solutions provider as opposed to simply a particle testing lab. PTL’s analytical staff has many years of experience designing test methods and performing custom analysis for cosmetic, skin care, fragrance and personal hygiene samples.

We're experts in rheology - the science of flowability - and that's essential to beauty product applications. The particle size of powdered cosmetics is of tremendous importance in how they flow and cover and can directly affect their appearance as well as the user’s skin.

Common Samples: Lotions, Spray Pumps, Powders, Particles suspended in gels, Binders, Pigments, Toothpaste

Analytical Testing: Particle Size, Surface Area, Image Analysis, Zeta Potential, Droplet Particle Size Analysis

PTL's laboratory is cGMP compliant, registered with the FDA and holds a DEA and ATF permits. PTL's consulting solutions open up the full range of what is possible in a beauty product particle testing method. Click here to request a quote or for more information.
