Cosmetics refer to any material cosmetic or physical, which is applied to the skin in order to alter its physical nature, appearance or feel. Cosmetics constitute a wide range of substances that can be classified into two broad categories: organic and inorganic. Organic cosmetics are made from natural compounds, derived from plants, animals or both, whereas inorganic cosmetics derive from minerals, man-made materials, synthetic organic chemicals and petroleum. Cosmetics can be categorized further into “natural” and “artificial” cosmetics. Natural cosmetics, such as soap, lotion, creams, and makeup (e.g. waterproof mascara, eyeliners and eyelashes), are generally considered safe and effective, whereas artificial cosmetics, such as nail polish and foundation, are not.
Cosmetics include various kinds of chemicals, dyes, emulsifiers, additives, preservatives, surfactants and lubricants. Some of them are commonly used in industrial cosmetic productions and processing, while others are utilized in natural health care products. Natural cosmetics include botanicals, aroma substances, alkaloids, caffeine, fragrance, coloring, bitter orange, citrus, Eurycoma Longifolia (ebrowns) extract, horsetail, mint, marine algae, myrrh, folic acid, pantothenic acid, pau d’arco, saccharin, selenium, synthetic oils, vitamins, vanillin, wheat germ oil and vinegar (e.g. mouthwash) https://beecost.vn/sua-rua-mat-innisfree.html.
Among the chemicals contained in natural cosmetics, some of the most common are alkaline soaps (which usually include sodium bicarbonate, calcium carbonate, potassium hydroxide, calcium thioglycolate or potassium monohydroxide), astringents, antibacterial and antimicrobial agents, fatty acids (such as propylene glycol or vegetable oils), preservatives, sunscreen agents, ultraviolet light blockers and triclosan (a strong organically produced antibacterial agent found in many cosmetics). Triclosan is derived from choline, a chemical compound found in all bacteria, viruses and other micro-organisms. When a normal bacterium grows in an unclogged wound, tetracycline is released to kill invading microorganisms. However, when this compound is exposed on the skin to an abrasive, such as when cosmetic products are applied, it releases toxins that cause irritation, itching and redness. The only way to avoid this chemical reaction is to use organic cosmetics.
Preservatives such as parabens and phthalates are widely used in cosmetics because they are cheap and effective preservatives. In addition, these chemicals can be applied in small amounts to help extend shelf life. However, research has shown that parabens and phthalates can cause cancer. So, always read the label on cosmetic products before purchasing and if you have questions about a specific ingredient (for example, parabens), do not hesitate to contact the manufacturer.
To improve product safety, all cosmetic products should be produced according to the highest international quality standards. The Food and Drug Administration (FDA) has established to set guidelines for the production of cosmetics, but even the FDA cannot guarantee that cosmetics will be safe when directly applied by consumers. The best way to ensure cosmetics are safe is to purchase them from a reputable company that has signed the “Compact for Safe Cosmetics”. The company must also meet the requirements of the Cosmetic Ingredient Review Council (CIRCC).
Cosmetics manufacturers in Australia need to be aware of the health risks associated with some of the ingredients that they use in their products. For example, one of the main ingredients in anti-aging cosmetics in the U.S. is retinol. This substance has been banned in some countries due to the possibility of increasing cancer rates. However, in Australia, cosmetics are not covered by the Cosmetics Regulations 2021. Cosmetics manufacturers are required to list the cosmetic ingredients that are included in their products on the ingredients label, but they are not required to indicate whether the ingredient is approved by the FDA or not.
