“A drug is not considered a new drug only when it is generally recognized as safe and effective (GRASE). GRASE: defined by the FDA OTC Glossary ( ) UVFs are also used in consumer cosmetics (makeup, nail polish, shampoo, etc.) and industry (plastics, paints, sealants, etc.) to protect against photodegradation.Įnvironment: the surroundings or conditions in which a person, animal, or plant lives or operates.Įcosystem: the interactions between the environment and the organisms that dwell within it.

The National Library of Medicine databases sometimes refer to these compounds as s unscreening agents (confusing to all of us at times), and define them as chemical or physical agents that protect the skin from sunburn and erythema by absorbing or blocking ultraviolet radiation. Environmental chemists categorize them in several ways, for example, organic vs. These are typically divided these into chemical (absorbing UV rays and converting to thermal energy) vs. UV filter: a specific compound that impedes the passage of UV light. These ingredients also help to prevent diseases such as sunburn and may reduce the chance of premature skin aging, skin cancer, and other harmful effects due to the sun when used in conjunction with limiting sun exposure and wearing protective clothing.”
Sunscreen active ingredients affect the structure or function of the body by absorbing, reflecting, or scattering the harmful, burning rays of the sun, thereby altering the normal physiological response to solar radiation. Broad spectrum sunscreens are defined by the FDA as products that provide UVA protection that is proportional to its UVB protection ( Food and Drug Administration (US), 2017, Food and Drug Administration (US), 2019a).Īccording to the FDA, “a product that includes the term “sunscreen” in its labeling or in any other way represents or suggests that it is intended to prevent, cure, treat, or mitigate disease or to affect a structure or function of the body comes within the definition of a drug in section 201(g)(1) of the act. In addition, they contain many other substances, such as emollients, preservatives or stabilizers, emulsifiers, fragrances, and coloring compounds. Sunscreens contain one or more UVFs that may be physical, chemical, or both. Sunscreen: a commercial product sold to consumers for protection of human skin from UV radiation. It is a UV filter (UVF) that is included in many commercial products known as sunscreens. For example, titanium dioxide (TiO 2) is not a sunscreen. When reviewing scientific data, it is essential that readers understand the terminology.
