Dosage of adjuvants

Adjuvants encompass a wide variety of substances used to modify, stabilize, or improve the properties of a product. They include emulsifiers, preservatives, plasticizers, solvents, antioxidants, and texturizing agents. Present in food, cosmetic, and pharmaceutical formulations, as well as in plastic materials and packaging, these compounds play a key role in the performance and durability of finished products. Their laboratory measurement is essential to ensure regulatory compliance, consumer safety, and control of manufacturing processes.

Analytical methods for the determination of adjuvants

The choice of method depends on the nature of the adjuvant to be analyzed and the matrix in which it is incorporated.

• HPLC (High Performance Liquid Chromatography) : used to detect and quantify organic additives such as emulsifiers or preservatives in food and cosmetic formulations.
• LC-MS (Liquid Chromatography coupled with Mass Spectrometry) : sensitive method for identifying and characterizing complex molecules or those present at low concentrations.
• ICP-MS and ICP-AES/ICP-OES (Inductively Coupled Plasma Mass or Atomic Emission Spectrometry) : suitable for the quantification of inorganic elements, particularly metals used as catalysts or stabilizers.
• GC (Gas Chromatography) : Often applied to the analysis of plasticizers and volatile solvents.

These approaches address a variety of quality control, identification, and regulatory compliance needs. For more information, see our HPLC, LC-MS/MS, and ICP-MS pages.

Industrial applications and sectors concerned

The dosage of adjuvants concerns several strategic sectors:

• Food industry : control of the presence of additives and emulsifiers in processed products.
• Cosmetics : verification of the conformity of preservatives, antioxidants and texturizing agents in skin or hair formulations.
• Packaging and polymer materials : analysis of plasticizers, solvents and stabilizers to assess potential migration to food or cosmetics.
• Pharmaceutical industry : validation of the quality of excipients and adjuvants used in drug formulations.

These services are part of a broader framework of material and product safety, in addition to analyses targeting compounds such as bisphenol A or BADGE , frequently sought in plastic packaging.

Matrices analyzed for adjuvants

The analysis can be applied to a wide variety of matrices: food and beverages, finished cosmetics (creams, lotions, shampoos), raw material extracts, polymers and plastic packaging, pharmaceutical products. Each matrix presents specific analytical constraints, requiring an appropriate methodological choice to obtain accurate and reliable results.

Importance of compliance and traceability

European regulations (REACH, cosmetic regulations, food regulations) require strict monitoring of substances added to formulations and materials. The dosage of adjuvants allows: to control compliance with regulatory thresholds, to guarantee the safety of products placed on the market, to identify possible cross-contamination or unwanted migrations, to ensure complete traceability of the manufacturing process. These objectives are similar to those of specific analyses on biogenic amines such as tyramine or tryptamine , also essential for quality control and product safety.
