 Safety of Nanomaterials in Cosmetics

What Is Safety Assessment of Nanomaterials in Cosmetics?

The use of nanotechnology in the cosmetic industry has been on a rapid rise in recent years. With unique properties such as enhanced absorption, higher stability, and increased potency, in addition to visual and textural improvements, nanomaterials have become popular among cosmetic formulators. However, the safety of these materials remains a significant concern.

The safety assessment of nanomaterials in cosmetics is a complex process that involves evaluating the materials' properties, toxicity, and exposure routes. Alfa Chemistry, as a leading chemical and analytical testing laboratory, offers a comprehensive portfolio of services to assess the safety of nanomaterials in cosmetics.

Our team of experienced scientists provides an array of testing and evaluation services to support research and development of nanotechnology in cosmetics of our customers. By using a range of assays, a comprehensive evaluation of nanomaterials can be obtained, leading to the development of safer and more efficient cosmetic products.

 Safety of Nanomaterials in Cosmetics

  • Physicochemical Characterization

The physicochemical characterization service offers a detailed analysis of the properties of nanomaterials such as particle size and distribution, aggregation and agglomeration, zeta potential/surface charge, catalytic activity, morphology (shape, crystallinity, surface topology, etc.), solubility, density, stability, and porosity.

Various techniques are used in combination to assess the safety and efficacy of nanomaterials used in cosmetics. The characterization techniques used for physicochemical characterization of nanomaterials in cosmetics include:

  • Transmission Electron Microscopy (TEM) - It is used to determine the size, shape, and distribution of nanoparticles in cosmetics.
  • Dynamic Light Scattering (DLS) - It is used to measure the size and size distribution of particles, and the zeta potential, which is an indicator of particle stability.
  • Fourier Transform Infrared Spectroscopy (FTIR) - It is used to identify functional groups and chemical bonds present in nanomaterials.
  • X-ray Diffraction (XRD) - It is used to determine the crystal structure of nanoparticles in cosmetics.
  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS) - It is used to determine the elemental composition and concentration of nanoparticles in cosmetics.
  • Photoluminescence (PL) spectroscopy - PL spectroscopy is used to determine the photophysical properties of nanoparticles in cosmetics.
  • In-vitro Toxicity Evaluation

Our experts conduct various in-vitro toxicity assays, including cytotoxicity, genotoxicity, and oxidative damage tests, to assess the safety of nanomaterials in cosmetics. For example, MTT assay can measure the metabolic activity of cells and can indicate if a nanomaterial is toxic to cells. Lactate dehydrogenase (LDH) assay measures the leakage of LDH from cells, which can indicate cell membrane damage and cytotoxicity.
