How Does CIR Work?
CIR (Cosmetic Ingredient Review) staff members conduct extensive literature searches, compile data, and prepare draft reports on high-priority ingredients. They organize the literature into several categories: chemistry (including physical properties and manufacture), use (cosmetic and non-cosmetic), general biology (with absorption, distribution, metabolism, and excretion data), and animal toxicology (acute, short-term, subchronic, and chronic studies, as well as dermal irritation and sensitization data).
The staff also prepares a clinical assessment of the ingredients that may include epidemiologic studies, along with classic repeated insult patch tests. In vitro test data are also gathered and incorporated into the review.

How Does The EWG Work.
(EWG) Environmental Working Group’s mission is to use the power of information to protect human health and the environment. … They used that information to create EWG’s Guide to Healthy Cleaning, which provides you with easy-to-navigate hazard ratings for a wide range of cleaners and ingredients.
Every product and ingredient in Skin Deep® gets a two-part score – one for hazard and one for data availability.
A product’s hazard score is not an average of the ingredients’ hazard scores. It is calculated using a weight-of-evidence approach that factors in all of the hazards or health impacts associated with the ingredients.
The Skin Deep ingredient hazard score, from 1 to 10, reflects known and suspected hazards linked to the ingredients.
