What does hydrotrope mean?
What does hydrotrope mean?
A hydrotrope is a compound that solubilizes hydrophobic compounds in aqueous solutions by means other than micellar solubilization. Typically, hydrotropes consist of a hydrophilic part and a hydrophobic part (similar to surfactants), but the hydrophobic part is generally too small to cause spontaneous self-aggregation.
Is sodium xylene sulfonate a hydrotrope?
Sodium xylene sulfonate is an example of a hydrotrope. This surfactant is used in personal care products, primarily shampoos, for its ability to serve as a clarifier or wetting agent. It helps formulas to spread easily and ensure efficient cleansing.
What is meant by Hydrotropic agents?
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.
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 is the meaning of Chemotropic?
: orientation of cells or organisms in relation to chemical stimuli.
What does sodium xylene sulfonate do?
Sodium Xylene Sulfonate is a surfactant found in personal care products, primarily in shampoos, because of its ability to serve as a claritant or wetting agent that helps a formula spread more easily and ensure efficient cleansing, according to Johnson& Johnson.
What is a surfactant and what does it do?
Surfactant, also called surface-active agent, substance such as a detergent that, when added to a liquid, reduces its surface tension, thereby increasing its spreading and wetting properties. Surfactants are used in corrosion inhibition, in ore flotation, to promote oil flow in porous rocks, and to produce aerosols.
Is Hydrotropism positive or negative?
What is hydrotropism in simple words?
hydrotropism. [ hī-drŏt′rə-pĭz′əm ] The growth or movement of a fixed organism, especially a plant, or a part of an organism toward or away from water. Roots often display hydrotropism in growing towards a water source.
Which is the best definition of a hydrotrope?
Freebase(0.00 / 0 votes)Rate this definition: Hydrotrope. A hydrotrope is a compound that solubilises hydrophobic compounds in aqueous solutions. Typically, hydrotropes consist of a hydrophilic part and a hydrophobic part but the hydrophobic part is generally too small to cause spontaneous self-aggregation.
Who is the inventor of the hydrotrope compound?
Exactly 100 years ago, the term “hydrotrope” was coined by Neuberg, for compounds that increase the solubility of sparingly soluble organic substances in water . “Hydrotropy” has later been introduced to describe the action of a hydrotrope.
How does a hydrotrope increase solubility of a solvent?
To form a hydrotrope, an aromatic hydrocarbon solvent is sulfonated, creating an aromatic sulfonic acid. It is then neutralized with a base. Additives may either increase or decrease the solubility of a solute in a given solvent. These salts that increase solubility are said to ‘salt in’ the solute and those salts…
What are the different ways to solubilize a hydrophobic solute?
Different ways to solubilize a hydrophobic solute are presented. The action of a hydrotrope is compared to that of a co-solubilizer and that of a surfactant. The concepts “hydrotrope” and “hydrotropy” are reviewed with a strong focus on the literature from recent years.
