However, as with cold sores and shingles, Valtrex is not a cure for genital herpes. Valtrex was approved for treating chickenpox in children based on studies of acyclovir (ZoviraxÂ®), a very similar medication. Other studies have shown that Valtrex (which the body transforms into acyclovir) is safe in children.
Polyvinyl alcohol. Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. It has the idealized formula [CH2CH(OH)]n. It is used in papermaking, textiles, and a variety of coatings. It is white (colourless) and odorless. It is sometimes supplied as beads or as solutions in water.
PVA (polyvinyl acetate). PVA's are the traditional wood glues, and some of the most common adhesives. They are also called aliphatic resins. They provide a strong wood-to-wood bond but will not adhere strongly or consistently to nonporous materials, such as metal or plastics.
