Professional cosmetic pretreatment technology at Protheragen-ING

Cosmetics products have various properties, including solids, liquids, emulsions, gels, pastes, etc., so it is hard to directly analysis and detect the ingredients. It is necessary to adopt appropriate pretreatment technology for the samples according to the detection objectives to eliminate the interference of excipients and enrich the compound to be measured in the sample for accurate analysis and detection. Protheragen-ING has experienced experts in this field who perform different pretreatments on samples based on different products and different analysis methods. We employ both traditional sample preparation for example direct dilution, liquid–liquid extraction (LLE), or solid–liquid extraction (SLE) as well as advanced techniques such as:

Solid-phase extraction (SPE) & Solid-phase microextraction (SPME): For liquid and semi-liquid/semi-solid products such as creams, toners, etc.

Accelerated Solvent Extraction (ASE): For cream products such as lipstick and mascara. The sample needs to have good thermal stability.

Ultrasound-assisted extraction (UAE): For solids such as eye shadow, blush, and other pressed powder products.
