What is mean by hydrotropic agents?
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.
Is ethanol a Hydrotrope?
Such precursors are achievable by dissolving the MO in a hydrotrope, such as ethanol, and preventing formation of liquid crystalline systems, instead forming concentrated liquid precursors.
Is citric acid a Hydrotrope?
Some of the hydrotropic agents are ascorbic acid, benzoic acid, citric acid, nicotinamide, sodium benzoate, urea, lysine etc., The hydrotropes are formed by mixing the drug with the hydrotropic agent in water.
What is hydrotropic method?
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.
Are hydrotropes distinct from surfactants?
This kind of behavior tends to suggest that the short chain hydrotropes have a notably different thermodynamic behavior as compared to longer chain “surfactants”. Hence, based on the analysis alone, it could be concluded that hydrotropes are a distinct class from surfactants….Figure 2.

What do you mean by solubilization?
Solubilization is the action of certain chemical reagents on organic materials (such as animal or plant tissue) that effects a structural breakdown (or digestion) into a liquid form that can then be directly dissolved in a liquid scintillation cocktail.
Is sodium benzoate a Solubilizer?
On the other hand, the hydrotropic salts, sodium benzoate, sodium salicylate, and sodium gentisate, are shown to be the best water solubilizers in 1-butanol. Sodium salicylate showed the maximum solubilizing power.
Is sodium benzoate a Hydrotrope?
Hydrotropic solubilization is one of them. In the present study, sodium benzoate was chosen as hydrotrope to enhance the solubility of Lornoxicam for its spectrophotometric estimation in their marketed formulation.
Is hydrotropism 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 is sodium xylene sulfonate?
Definition. Sodium xylene sulfonate is a wetting agent that can also be found in hair care products and cleansers. We use it in our products to help a formula spread across a surface, making cleaning more efficient.
What is solubilization in pharmacy?
Handbook of Modern Pharmaceutical Analysis Solubilization is the increase in solubility of a poorly water–soluble substance with surface-active agents.
