Helps dissolve other soluble ingredients. Helps the mechanical process of cleaning teeth in mouthwashes.
Glycerol (also called glycerine or glycerin) is a simple polyol compound.
Glycerin is mildly antimicrobial and antiviral and is an FDA approved treatment for wounds. The Red Cross reports that an 85% solution of glycerin shows bactericidal and antiviral effects, and wounds treated with glycerin show reduced inflammation after roughly 2 hours. Due to this it is used widely in wound care products, including glycerin based hydrogel sheets for burns and other wound care. It is approved for all types of wound care except third degree burns, and is used to package donor skin used in skin grafts. There is no topical treatment approved for third degree burns, and so this limitation is not exclusive to glycerin.
Glycerol is used in medical, pharmaceutical and personal care preparations, often as a means of improving smoothness, providing lubrication, and as a humectant.
In toothpastes Glycerol holds onto water and prevents the toothpaste from drying out in the tube, and also prevents dryness in the mouth during brushing.
It can help reduce bacterial activity by reducing the available water activity and therefore has a protective action against tooth decay. Glycerin does not damage gums or tooth enamel.
Glycerin as ingredient of foods,cosmetic products ,toothpaste and ...may cause : Upset stomach, Stomach cramps, Gas, Diarrhea, Burning, Rectal irritation.
Glycerin does not damage gums or tooth enamel.
it can cause allergic reactions.
Potassium alginate is widely used in food products. It is currently used as an excipient only in experimental pharmaceutical formulations.
Some people may have an allergic reaction to potassium sorbate in foods. These allergies are rare. Allergies to potassium sorbate are more common with cosmetics and personal products, where it can cause skin or scalp irritation. However, the Environmental Working Group has rated potassium sorbate with a low risk as a skin irritant.
If you use potassium sorbate as a pure ingredient, for example in winemaking, it can irritate your eyes and skin if you spill it.
Despite purity requirements for manufacturers, it’s possible that potassium sorbate as a food additive can be contaminated. It may be contaminated with:
Propylene glycol is “generally recognized as safe” (GRAS) by the US Food and Drug Administration (FDA).
In the US, it can be used as a direct and indirect food additive. In Europe, it is only allowed to be used in food as a solvent for colors, emulsifiers, antioxidants and enzymes, with up to 0.45 grams per pound (1 gram/kg) allowed in the final food product.
The World Health Organization recommends a maximum intake of 11.4 mg of propylene glycol per pound of body weight (25 mg/kg) per day. The estimated exposure to propylene glycol through foods in the US is 15 mg per pound (34 mg/kg) per day.
In comparison, one person who developed symptoms of toxicity was receiving 213 grams of propylene glycol per day. For a 120-pound (60-kg) adult, that is over 100 times what is found in the average diet .
There is only one documented case of toxicity caused by food.
A man drank very large amounts of cinnamon whiskey containing propylene glycol and was found unconscious. While his symptoms were also due to the alcohol, some could be attributed to the propylene glycol.
Overall, apart from people with allergies and one case of excessive consumption, there have been no other reported cases of negative or toxic effects of propylene glycol in foods.
However, as current intakes are estimated to be above the recommended level, it may be wise to reduce dietary sources where you can, especially as the primary sources are highly processed foods.
The takeaway. Silicon dioxide exists naturally within the earth and our bodies. There isn't yet evidence to suggest it's dangerous to ingest as a food additive, but more research is needed on what role it plays in the body. Chronic inhalation of silica dust can lead to lung disease.
Studies suggest that sodium benzoate may increase your risk of inflammation, oxidative stress, obesity, ADHD, and allergies. It may also convert to benzene, a potential carcinogen, but the low levels found in beverages are deemed safe.
In the United States, sodium benzoate is designated as generally recognized as safe (GRAS) by the Food and Drug Administration. The International Programme on Chemical Safety found no adverse effects in humans at doses of 647–825 mg/kg of body weight per day.
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.
Xylitol is generally well tolerated, but some people experience digestive side effects when they consume too much. The sugar alcohols can pull water into your intestine or get fermented by gut bacteria. This can lead to gas, bloating and diarrhea.
