If he had autism he wouldn't be very social, but very shy. I don't think flapping his arms is a sign of autism, but if you're concerned about it, ask a neurologist about it, or his doctor, either way. :) â¥ Cute T â¥ Â· 9 years ago.
If it weren't for food preservatives, we couldn't enjoy many of the great foods the world has to offer. Common antimicrobial preservatives include sodium nitrate, calcium propionate, disodium EDTA, potassium sorbate, sodium benzoate, and sulfites.
A preservative is a natural or synthetic ingredient that is added to products such as foods, pharmaceuticals and personal care products to prevent spoilage, whether from microbial growth or undesirable chemical changes.n most cases, preservative ingredients are used to protect the product and help it remain safe and perform as intended over the lifetime of the product. These products are regulated in the US by FDA under the cosmetic previsions of the law and manufacturers must determine that they are safe for consumer use.
