Consumer demand for natural colors in food, drugs, and cosmetics is rising. However, these natural color additives lack FDA evaluation, increasing risks of adulteration and contamination, necessitating industry-wide safety standards.
Area of Science:
- Food Science
- Regulatory Science
- Cosmetic Science
Background:
- Color additives are crucial in food, drug, and cosmetic products, influencing consumer purchasing decisions.
- The U.S. Federal Food, Drug, and Cosmetic Act (FD&C Act) defines color additives and categorizes them under FDA regulations.
- While certified colors undergo strict quality control, naturally sourced colors are exempt from FDA certification.
Purpose of the Study:
- To highlight the increasing market application of natural colors.
- To address the risks associated with the lack of FDA evaluation for natural colors.
- To emphasize the need for consistent industry-wide safety standards for natural color additives.
Main Methods:
- Analysis of U.S. Food and Drug Administration (FDA) regulations regarding color additives.
- Examination of the definition and categorization of color additives under the FD&C Act.
- Review of the safety and quality control differences between certified and natural colors.
Main Results:
- Consumer preference is shifting towards natural colors, increasing their market presence.
- Natural colors lack FDA evaluation and standardized quality specifications, posing risks.
- Potential for economic adulteration, misbranding, and contamination (physical, chemical, microbial) in natural colors is significant.
Conclusions:
- The popularity of natural colors presents challenges due to a lack of regulatory oversight and defined safety standards.
- Adulteration risks range from mislabeling to serious contamination from sourcing and processing.
- Development of consistent, industry-wide safety standards is essential for natural color manufacturing, processing, application, and trade to ensure product quality and safety.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
