Physical & Chemical Specification

Cosmetics are a mixture of many materials, and an understanding of physical and chemical property is essential in designing, manufacturing, and ensuring the stability of cosmetics. Our service object include physical and chemical characteristics of the substances or mixtures, as well as the cosmetic product.

Physical analysis, often paired with chemical testing, is the measurement of any physical property that could be important to a cosmetic product. It can be used on raw ingredients or to tell the difference between possible formulations of a new release product, or even in quality control once the product is on the market.

Instrumental, clinical, and sensory analysis are all used to as our methods to analyze physical and chemical characteristics. In all, instrumental method is the least subjective with the least bias on human perception and consumer preference. Although instrumental method is precise and sensitive, it cannot be used to measure the whole product. Thus different components of a product are tested by instrumental method and combined with sensory testing.

Our physical test parameters include:

  • Color
  • Density-Specific Gravity
  • Viscosity
  • Melting point or boiling point
  • Hardness-Softness
  • Foam Tests
  • Accelerated stability tests

Chemical tests include:

  • Acidity
  • Alkalinity
  • Assay of particular active ingredient
  • ...
