Dosage of pesticides

Pesticide analysis allows for the detection and quantification of pesticide residues in a wide variety of matrices: plants, natural extracts, cosmetic ingredients, food, or environmental samples .
This analysis is essential to ensure the safety of finished products , regulatory compliance , and the quality of plant-based raw materials used in cosmetic and nutraceutical formulations.

Pesticide residues can originate from the cultivation, storage, or processing of raw materials. Therefore, their control is essential for products based on plant extracts , essential oils , or organic ingredients intended for skin or hair care.

Analytical methods: GC-MS/MS and LC-MS/MS

Pesticide analysis relies on high-precision chromatographic methods, adapted to the detection of hundreds of molecules at trace levels (ppb):

• LC-MS/MS (Liquid Chromatography coupled with tandem mass spectrometry) : suitable for polar compounds, such as herbicides, fungicides and growth regulators.
• GC-MS/MS (Gas Chromatography coupled with tandem mass spectrometry) : used for more volatile molecules such as organochlorines, organophosphates or carbamates.

These two approaches allow for the application of a multi-residue method covering more than 500 active substances , in accordance with European regulations (Regulation (EC) No 396/2005). Maximum residue limits (MRLs) are controlled with high precision.

Applications in the cosmetics and plant sectors

Pesticide dosage applies to many products:

• Cosmetic ingredients : vegetable oils, plant extracts, powders, clays.
• Natural and organic products : validation of the absence of chemical residues.
• Plant-based raw materials : conformity check upon import or before processing.
• Food and nutraceutical products : safety of extracts for oral use.

This service can be complemented by the measurement of organophosphate and carbamate residues for an extended analysis .

Affected matrices

YesWeLab's partner laboratories perform pesticide analysis on:

• Cosmetic ingredients (extracts, oils, waxes, butters)
• Dried plants, powders and hydroalcoholic extracts
• Finished products (creams, lotions, gels, shampoos)
• Foods and nutraceutical products
• Soils, water and agricultural raw materials

Each method is optimized according to the analyzed matrix , the type of pesticide targeted and the required level of detection .
