It is unclear from the search results what "pé e mão manicureproduct" refers to. There are no relevant results that provide information on this topic. However, I can provide information on ingredients and materials used in cosmetics and their safety.

• Isopropyl Myristate: This is a common ingredient in cosmetics and personal care products, used as an emollient and thickening agent. It has been shown to be safe for use in cosmetics, but may cause irritation in some individuals.

• Yeast-derived ingredients: These are used in cosmetics and personal care products as skin conditioning agents, emollients, and humectants. The Cosmetic Ingredient Review (CIR) has determined that yeast-derived ingredients are safe for use in cosmetics.

• Parabens: These are preservatives used in cosmetics and personal care products to prevent the growth of bacteria and fungi. Some studies have suggested that parabens may have estrogenic effects and may be linked to breast cancer, but the evidence is inconclusive. The CIR has determined that parabens are safe for use in cosmetics at concentrations up to 0.4% .

• Natural food ingredients: Many consumers choose "green cosmetics" made with natural food ingredients, hoping that they are not harmful to health and the environment. However, the safety of these ingredients in cosmetics is not always clear, and some may cause skin irritation or allergic reactions. It is important to do research and consult with a dermatologist before using cosmetics with natural food ingredients.

Overall, the safety of ingredients and materials used in cosmetics is a complex issue, and it is important to do research and consult with a dermatologist before using any new product.
