Coconut on package labels as a "tree nut" with potential allergenicity. Cocamidopropyl betaine (CAPB) is a surfactant manufactured from coconut oil that is increasingly used as an ingredient in personal hygiene products and cosmetics, such as shampoos, liquid soaps, cleansers and antiseptics, among others. CAPB may cause mild skin irritation, but allergic reactions to CAPB are rare and probably related to impurities rendered during the manufacturing process (which include amidoamine and dimethylaminopropylamine) rather than CAPB itself. Many varieties of coconuts "C. nucifera" are being cultivated in many countries. These vary by the taste of the coconut water and color of the
Liquid metal this observation of "wetting by rubbing into glass surface" has created a widely spread misconception that the gallium-based liquid metals wet glass surfaces, as if the liquid breaks free of the oxide skin and wets the surface. The reality is the opposite: the oxide makes the liquid wet the glass. In more details: as the liquid is rubbed into and spread onto the glass surface, the liquid oxidizes and coats the glass with a thin layer of oxide (solid) residues, on which the liquid metal wets. In other words, what is seen is a gallium-based liquid metal wetting its solid
