Cocamidopropyl betaine is used as a foam booster in shampoos. It is a medium-strength surfactant also used in bath products like hand soaps. It is also used in cosmetics as an emulsifying agent and thickener, and to reduce irritation purely ionic surfactants would cause. It also serves as an antistatic agent in hair conditioners, which most often does not irritate skin or mucous membranes. However, some studies indicate it is an allergen.
CAPB has been claimed to cause allergic reactions in some users, but a controlled pilot study has found that these cases may represent irritant reactions rather than true allergic reactions. Furthermore, results of human studies have shown that CAPB has a low sensitizing potential if impurities with amidoamine (AA) and dimethylaminopropylamine (DMAPA) are low and tightly controlled. Other studies have concluded that most apparent allergic reactions to CAPB are more likely due to amidoamine. Cocamidopropyl betaine was voted 2004 Allergen of the Year by the American Contact Dermatitis Society.
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.
Limonene is considered safe for humans with little risk of side effects. The Food and Drug Administration (FDA) recognizes limonene as a safe food additive and flavoring . However, when applied directly to the skin, limonene may cause irritation in some people, so caution should be used when handling its essential oil . Limonene is sometimes taken as a concentrated supplement. Because of the way your body breaks it down, it’s likely safe consumed in this form. That said, human research on these supplements is lacking . Notably, high-dose supplements may cause side effects in some people. What’s more, insufficient evidence exists to determine whether limonene supplements are acceptable for pregnant or breastfeeding women. It’s best to consult your healthcare practitioner before taking limonene supplements, especially if you’re taking medications, are pregnant or breastfeeding, or have a medical condition.
Polyvinylpyrrolidone did not irritate or induce sensitization when applied to the skin of volunteers, and was not irritant to the eyes of rabbits. It was of low acute toxicity when administered by the intravenous route in humans or by the oral and intravenous routes in various species of laboratory animals.
Inhaling Potassium Hydroxide can irritate the lungs. Higher exposures may cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency. Exposure to Potassium Hydroxide can cause headache, dizziness, nausea and vomiting. Potassium hydroxide and its solutions are severe irritants to skin and other tissue.
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.
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.
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.
