Shampoos are commercially not available in the form of

ANS:B - gaseous mixture

A gaseous mixture refers to a combination of gases that are mixed together but not chemically bonded. In a gaseous mixture, each gas retains its own chemical identity and properties. The gases in the mixture are typically uniformly distributed throughout the space they occupy. In the context of shampoos, which are typically liquid formulations, it's not common for them to be available in the form of a gaseous mixture. Instead, shampoos are primarily composed of liquid components such as water, surfactants, conditioners, and other ingredients dissolved or dispersed in the liquid phase. Gaseous mixtures are not suitable for shampoo applications because they would not provide the desired cleansing and conditioning effects when applied to the hair and scalp.
