Currently, there are some chemicals we already know that are linked to cancer, autism and reproductive problems, but there are also other substances that are mistakenly thought to be harmful to health.
The following chemicals are sometimes considered "toxic" or "unsafe" , but they do not seem to really harm human health.
Aspartame (artificial sweetener) has been thought to cause cancer, but scientific evidence suggests it is not dangerous to health.
Aspartame has been badly known over the years for false reasons.
Most public concerns surrounding artificial sweeteners in studies of mice and aspartame with blood-related cancers such as leukemia and lymphomas. Both the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have suspected these findings and believe that aspartame is safe to consume.
For any chemical, its toxicity depends on the dose and frequency of exposure.
The real problem with aspartame is that it is found in diet soda, not necessarily healthy. Research has shown that dietary soda can increase your cravings for sugar and may even lead to obesity.
Saccharin has been rumored to cause cancer, but there are not many reasons to worry
Another study of mice has prompted a similar link between saccharin (a non-calorie sweetener sold under the brand name Sweet'N Low) and cancer. In the 1980s, saccharin-containing products were required to carry a warning label stating that this sweetener "was identified as causing cancer in laboratory animals".
The study was later removed after scientists found that mice were more likely to get bladder cancer right from the start. Dozens of other studies have also found no link between saccharin and cancer.
In 2016, the US National Toxicology Research Program removed saccharin from the list of carcinogenic ingredients.
Aluminum (Aluminum) in deodorant will not cause breast cancer
In the late 1990s, an email spread that aluminum in deodorant products could make people with breast cancer. This assertion is supported by preliminary research, but has been proven wrong.
Neither the European Commission's Scientific Commission on Consumer Safety and the American Cancer Society found any clear link between breast cancer and aluminum-containing antiperspirants.
Evidence shows that our bodies only absorb a small amount of aluminum from antiperspirants - not enough to be considered dangerous.
Paraben can actually prevent harmful bacteria from forming in your cosmetics
In 2004, a small study linking paraben (preservatives found in makeup and skin care products) with breast cancer, but still many shortcomings. The study looked for evidence of paraben in existing breast cancer tissue, but did not determine where they came from or whether they contributed to cancer.
There are also concerns that whether paraben can break down the hormone system in a way similar to estrogen, but parabens are much weaker than the body's natural estrogen.
The FDA has not found any concrete evidence that paraben in cosmetics affects human health. In fact, this chemical helps prevent harmful bacteria from forming in your makeup, lotion or sunscreen.
No, MSG will not cause you a headache
In 1968, a biomedical researcher said that she experienced numbness and tachycardia after eating at Chinese restaurants. He said the cause of his symptoms was due to a food additive called MSG (or monosodium glutamate) found in processed meats, fries, and canned vegetables.
In the 1990s, FDA was commissioned to evaluate additives and found that MSG is safe to consume. The review also shows that people with headaches, numbness or drowsiness are likely to eat large amounts of MSG on an empty stomach.
But MSG remains in vigilance: About 42% of Americans still try to avoid consuming this ingredient.
Sulfate in shampoo is really good, if you are not sensitive
Consumers will tend to buy "sulfate-free" shampoo or shower gel, but there is little reason to fear sulfate. These ingredients are a surfactant - basically a soap that makes it easier to remove grease.
In the 1990s, sulfate was thought to cause cancer - an unproven claim by scientific evidence. Therefore, those who should consider this ingredient are those with sensitive skin, because sulfate can both dry and irritate the skin.
