    Applicationem

    Copovidone polymerus aquaticum solutum usus est ad meliorandi uptationem et medicamentorum onerarias variarum agentium pharmaceuticorum, inclusa inaequalis contraceptiva.

    Poly(1-vinylpyrrolidone-co-vinyl acetate) principale materiae rudis medicaminum adhibentur pro pilis gel, mousse, shampoo, etc., necnon surfactants, pharmaceuticis et aliis usibus industrialibus. Praecipue adhibentur adhaesiones aquae solubiles et adhaesiones aridae in carunculatione et tabularum technologiae rectae, ut materias pellicularum in membrana membranarum pellicularum, et ut pororum substantias in agentibus larvatis formantibus. Ponitur pro saccharo efficiens ne crepuit. In fundo chemico efficiens ponitur pro causa humoris probationis. Vp/va series productorum copolymarum maxime adhibentur ut agentium filming-formantium et stylorum agentium in agro cosmeticorum, praesertim in agentium eruptione, gellorum pilorum, mousse et shampoo series productorum. Partes principales ludunt ut agens movens formans et agens stylus capillus. Si una cum pvpk30 adhibeantur, augebitur eorum usus effectus.

    Species est pulveris albi vel liquoris hyalinae. Genus regularis est Lorem-64.
