Helps dissolve other soluble ingredients. Helps the mechanical process of cleaning teeth in mouthwashes.
Hydrated silica is listed by the US Food and Drug Administration as "Generally Recognized as Safe", however one drawback of abrasives in toothpaste is that they may make some people's teeth sensitive, especially if they brush very hard and do not brush with a soft-bristled toothbrush. The dentin and the pulp that lie beneath the enamel are sensitive, says the American Dental Association (ADA), so that why it's key to have a strong enamel.
Whole Foods has deemed the ingredient acceptable in its body care and cleaning product quality standards. The National Institutes of Health report that the ingredient is not a skin or eye irritant, and the FDA has deemed it Generally Recognized as Safe.
Contact causes severe burns with redness, swelling, pain and blurred vision. Permanent damage including blindness can result. Ingestion: Can burn the lips, tongue, throat and stomach. Symptoms may include nausea, vomiting, stomach cramps and diarrhea.
The Food and Drug Administration (FDA) regards SLS as safe as a food additive.
Regarding its use in cosmetics and body products, the safety assessment study of SLS, published in 1983 in the International Journal of Toxicology (the most recent assessment), found that it’s not harmful if used briefly and rinsed from the skin, as with shampoos and soaps.
The report says that products that stay on the skin longer shouldn’t exceed 1 percent concentration of SLS.
However, the same assessment did suggest some possible, albeit minimal, risk to humans using SLS. For example, some tests found that continuous skin exposure to SLS could cause mild to moderate irritation in animals.
Nevertheless, the assessment concluded that SLS is safe in formulations used in cosmetics and personal care products. Because many of these products are designed to be rinsed off after short applications, the risks are minimal.
According to most research, SLS is an irritant but not a carcinogen. Studies have shown no link between the use of SLS and increased cancer risk.
According to a 2015 study, SLS is safe for use in household cleaning products.
In the 1970s, studies performed on laboratory rats found an association between consumption of high doses of saccharin and the development of bladder cancer. However, further study determined that this effect was due to a mechanism that is not relevant to humans.Epidemiological studies have shown no evidence that saccharin is associated with bladder cancer in humans.The International Agency for Research on Cancer (IARC) originally classified saccharin in Group 2B ("possibly carcinogenic to humans") based on the rat studies, but downgraded it to Group 3 ("not classifiable as to the carcinogenicity to humans") upon review of the subsequent research.
Saccharin has no food energy and no nutritional value. It is safe to consume for individuals with diabetes.
People with sulfonamide allergies can experience allergic reactions to saccharin, as it is a sulfonamide derivative and can cross-react. Saccharin in toothpaste can cause burning sensations, swelling, and rashes of the mouth and lips in sensitive individuals.
Ingesting large amounts of sorbitol can lead to abdominal pain, flatulence, and mild to severe diarrhea. Habitual sorbitol consumption of over 20 grams (0.7 oz) per day as sugar-free gum has led to severe diarrhea, causing unintended weight loss or even requiring hospitalization. In early studies, a dose of 25g of sorbitol, eaten through the day, produced a laxative effect in only 5% of individuals. As a result of the large molecular weight of sorbitol, when large amounts of sorbitol are ingested, only a small amount of sorbitol is absorbed in the small intestine, and most of the sorbitol enters the colon, with consequent gastrointestinal effects.
Stannous Chloride can cause headache, nausea, vomiting and fatigue.
Some of the most commonly reported adverse effects include:
Seizures, dizziness, and migraines.
Blood sugar increases and weight gain.
Main Routes of Exposure: Inhalation; skin contact; eye contact.
Inhalation: At high concentrations: can irritate the nose and throat.
Skin Contact: May cause mild irritation.
Eye Contact: May cause slight irritation as a "foreign object". Tearing, blinking and mild temporary pain may occur as particles are rinsed from the eye by tears.
Ingestion: Not harmful.
Effects of Long-Term (Chronic) Exposure: Conclusions cannot be drawn from the limited studies available.
Carcinogenicity: Possible carcinogen. May cause cancer based on animal information. Has been associated with: lung cancer.
For most people, eating foods that contain xanthan gum appears to be completely safe.
While many foods contain it, it only makes up about 0.05–0.3% of a food product.
Moreover, a typical person consumes less than 1 gram of xanthan gum per day. Amounts 20 times that have been proven to be safe.
In fact, the Joint Expert Committee on Food Additives assigned it an acceptable daily intake of “not specified.” It gives this designation when food additives have a very low toxicity, and levels in foods are so small that they do not pose a health hazard.
But people should avoid inhaling xanthan gum. Workers who handled it in powder form were found to have flu-like symptoms and nose and throat irritation.
So even though you may eat many foods containing it, your intake is so small that you’re unlikely to experience either benefits or negative side effects.
When used as directed, zinc supplements can be a safe and effective way to increase your zinc intake and improve several aspects of your health.
However, they have been associated with adverse side effects, including nausea, vomiting, diarrhea, and stomach pain
Exceeding 40 mg per day of elemental zinc can cause flu-like symptoms, such as fever, coughing, headache, and fatigue .
Zinc can also interfere with your body’s ability to absorb copper, potentially leading to a deficiency in this key mineral over time.
Furthermore, zinc supplements have been shown to interfere with the absorption of certain antibiotics, reducing their effectiveness if taken at the same time.
To reduce your risk of side effects, stick to the recommended dosage and avoid exceeding the tolerable upper limit of 40 mg per day — unless under medical supervision.
If you experience any negative side effects after taking zinc supplements, decrease your dosage and consider consulting with your healthcare professional if symptoms persist.
