I use their numbers as a general guideline and if I think I'd like to use a product with an orange code, I check the ingredients. They don't distinguish between uses of ingredients in giving them safety ratings AFAIK. So with products containing alcohol as an ingredient, the safety data includes liver damage, neurotoxicity, etc. I am not so worried about using small amounts of alcohol in a skincare product.
So if it's green, I'm happy and if it's not, I make up my own mind on a case-by-case basis. I try really hard to avoid things noted as endocrine disruptors.
