What is hydrotropic solubilization?
Hydrotropic solubilization is a technique used to increase the aqueous solubility of poorly water-soluble drugs and the present study was aimed at developing a hydrotropic technique to increase the solubility of lornoxicam, using 2 M sodium benzoate as the hydrotropic agent.
What is meant by hydrotropic agent?
Introduction. Hydrotropic agents, according to the definition first put forward by Neuberg. (1916), are metal salts of organic acids which at fairly high concentrations, consider- ably increase the aqueous solubility of organic substances normally slightly soluble. in water.
Which are the Hydrotropic substances?
Examples of hydrotropes include urea, tosylate, cumenesulfonate and xylenesulfonate. The term hydrotropy was originally put forward by Carl Neuberg to describe the increase in the solubility of a solute by the addition of fairly high concentrations of alkali metal salts of various organic acids.
What is Hydro trophy?
Hydrotropy is a solubilization phenomenon whereby addition of large amount of second solute results in an increase in the aqueous solubility of another solute.
Which part of plant grows towards water?
Hydrotropism: Root growth responses to water.
Is Hydrotropism positive or negative?
The response may be positive or negative. A positive hydrotropism is one in which the organism tends to grow towards moisture whereas a negative hydrotropism is when the organism grows away from it. An example of positive hydrotropism is the growth of plant roots towards higher relative humidity level.
What do you mean by solubilization?
Solubilization is the formation of a thermodynamically stable, isotropic solution of a substance (the solubilizate), normally insoluble or slightly soluble in water, by the addition of a surfactant (the solublizer).
What are hydrotropes used for?
Hydrotropes are used to adjust the cloud point of the formulation. A higher concentration of hydrotrope generally leads to higher cloud points. Solvents and more-soluble surfactant classes can also be used to increase solubility.
What is sodium xylene sulfonate used for?
Sodium xylene sulfonate is used in liquid household detergents and shampoos, in degreasing compounds and printing pastes used in the textile industry in agents used to extract pentosans and lignin in the paper industry, and as a glue additive in the leather industry.
What is Hydrotropic movement example?
Hydrotropism means the tendency to grow or tend to reach the area with moisture content like the movement of roots towards high humidity level. Examples of hydrotropism plants are tomato roots, radish roots or even carrots.
Why do roots show Hydrotropic movement?
The process of hydrotropism is started by the root cap sensing water and sending a signal to the elongating part of the root. Water readily moves in soil and soil water content is constantly changing so any gradients in soil moisture are not stable.
What is meant by Hydrotropic movement?
Hydrotropism is a form of tropism characterized by the growth or movement response of a cell or an organism to moisture or water. The response may be positive or negative.
