Polyvinyl acetate (PVA), a synthetic polymer, is generally considered non-toxic. It is widely used in adhesives, paints, and even in chewing gum base. Due to its non-toxic nature, PVA is preferred in school projects and household crafts. Despite its safety, it's recommended not to ingest it or inhale its dust. PVA might cause irritation when it comes into contact with the skin or eyes in its liquid form before drying. In industrial settings, proper safety measures are advisable to mitigate any potential risks associated with its handling. Overall, PVA is deemed safe for use in various applications when used as intended.
White yarn can indeed glow under blacklight, but it depends on the type of material and any optical brighteners it contains. Optical brighteners are chemical compounds that absorb light in the UV spectrum and re-emit it in the visible spectrum, making materials appear whiter. Many white fabrics and yarns are treated with these brighteners to enhance their appearance. Natural fibers like cotton, without added brighteners, might not glow as vividly as synthetic fibers or those treated with these compounds. When placed under a blacklight, materials with optical brighteners will fluoresce, creating a glowing effect. This property is useful in art and decor, adding an intriguing visual element to projects that involve white yarn.
Polyethylene glycol (PEG) is a polyether compound widely used in medical applications, cosmetics, and pharmaceuticals due to its solubility and non-toxicity. Generally recognized as safe by the FDA, its risk largely depends on the molecular weight and dosage. Low-molecular-weight PEG is used in laxatives and can cause dehydration or electrolyte imbalance if not used as advised. High-molecular-weight variants are less likely to be absorbed by the body, minimizing the risk of side effects. Allergic reactions to PEG, though rare, can occur and range from mild skin rashes to severe anaphylaxis. It's crucial to follow the recommended usage guidelines and consult with healthcare professionals, especially for individuals with known sensitivities or compromised health conditions.
