It can be difficult to determine the safety and toxicity of makeup products, as many harmful chemicals are not listed on product labels. However, there are resources available to help consumers make informed decisions about the products they use. Here are some key points from the search results:

• EWG Skin Deep Cosmetics Database: This database reviews every product to identify product type, use and composition, target demographic, and special product claims. It evaluates ingredients to empower consumers to purchase safer products.

• Harmful Ingredients: There are many harmful ingredients used in cosmetics and personal care products, including surfactants, formaldehyde, and ingredients listed as "fragrance". These ingredients can be toxic and have negative effects on health.

• Clean Beauty Brands: Some brands are leading the way in clean skincare and cosmetic industry reform, and are consistently ranked at the top of the list for clean skincare and beauty. Examples include Beautycounter and Crunchi.

• Ingredient Ratings: Think Dirty and EWG both provide ingredient ratings to help consumers determine the toxicity of products. Think Dirty uses publicly available data released by government and non-profit agencies in North America to assess risk, while EWG evaluates ingredients to generate a rating based on toxicity.

It is important for consumers to be informed and purchase products that are healthy and safe for them and the environment. Reading cosmetic labels is a great first step in being informed about what’s in your products, but it can be difficult to decipher the long, scientific-looking names of ingredients. Alternatively, consumers can use resources like the EWG Skin Deep Cosmetics Database or Think Dirty to determine the toxicity of products. Clean beauty brands like Beautycounter and Crunchi are also good options for those looking for non-toxic makeup products.
