Cosmetics

As demand for a product increases, a concern is that to achieve a faster speed to market this will lead to complex production processes and considerable investment in resources. From the initial research and development, ingredient selection to planning and preparation, businesses need to expedite and simplify the production processes to ensure they remain effective in the cosmetic market.

The common challenges faced by the cosmetics industry include new and increasingly complex technical challenges such as emulsion stability, metals impurity and thickening. These technical challenges often result in a high cost of production as well as wastage of time, energy and raw materials.

Recognizing that businesses must eliminate these barriers for maximum efficiency, sustainability and quality, DKSH offers a complete sample characterization solution for the physical and chemical properties of cosmetics ingredients alongside our expertise in addressing any issues relevant to the cosmetics industry.

Measurement types

Particle size distribution

Particle size analysis in the range 0.01-3500 microns. For nanoparticle analysis see dedicated section.

Morphology

Morphological analysis of particles in the range 0.5-10000 microns (size, shape and transparency of particles). Integrated Raman chemical analysis with MDRS (Morphologically Directed Raman Spectroscopy).

Nanoparticle characterization

Size, concentration and zeta potential anlysis of nano-systems using light scattering techniques such as DLS, ELS and NTA techniques.

Rheology, Viscosity and Powder Flowability

Viscosity measurement and visco-elastic properties characterization of liquid dispersions, complex fluids and semi-solid materials.

Stability analysis

Rapid and objective quantification of concentrated dispersion real stability using Multiple Light Scattering.

High pressure homogenizer

High pressure homogenizing technique to produce stable nanoemulsions, reduce particle size or molecular weight of polysaccharides, nanoencapsulation, de-agglomeration, etc.

Biomolecular interactions

Biomolecular interactions of proteins, antibodies, nucleic acids, lipids and other biomolecules using ITC Microcalorimetry or BioLayer Interferometry BLI techniques.

Elemental analysis

XRF provides both qualitative and quantitative information on a wide variety of sample types. It can quantify elements from beryllium (Be) up to americium (Am) in concentrations from 100% down to sub-ppm level.

Protein aggregate analysis

SEC is the standard method for protein aggregate analysis. The choice of pore size is related to the size of the molecule to be separated.

Phase identification

Phase identification is the most important application of X-ray diffraction (XRD). It is not only applied on powder samples but also on polycrystalline solids, suspensions and thin films.

Polymer characterization

Gel permeation chromatography (GPC) that separates analytes on the basis of size, typically in organic solvents. The technique is often used for the analysis of polymers.
