Preparation and Reactions of Sulfides02:26

Preparation and Reactions of Sulfides

Sulfides are the sulfur analog of ethers, just as thiols are the sulfur analog of alcohol. Like ethers, sulfides also consist of two hydrocarbon groups bonded to the central sulfur atom. Depending upon the type of groups present, sulfides can be symmetrical or asymmetrical. Symmetrical sulfides can be prepared via an SN2 reaction between 2 equivalents of an alkyl halide and one equivalent of sodium sulfide.
Electrophilic Aromatic Substitution: Sulfonation of Benzene01:22

Electrophilic Aromatic Substitution: Sulfonation of Benzene

Sulfonation of benzene is a reaction wherein benzene is treated with fuming sulfuric acid at room temperature to produce benzenesulfonic acid. Fuming sulfuric acid is a mixture of sulfur trioxide and concentrated sulfuric acid.
Ionic Strength: Effects on Chemical Equilibria01:19

Ionic Strength: Effects on Chemical Equilibria

The addition of an inert ionic compound increases the solubility of a sparingly soluble salt. For example, adding potassium nitrate to a saturated solution of calcium sulfate significantly enhances the solubility of calcium sulfate. Le Châtelier's principle cannot predict this shift in the equilibrium. Instead, this could be explained in terms of changes in the effective concentration of the ions in solution in the presence of added inert salt.
In this solution, the primary cation—the calcium...
SDS-PAGE01:27

SDS-PAGE

Gel electrophoresis is a method that separates biological macromolecules like nucleic acids or proteins by forcing them to pass through a gel matrix under an electric field.
A variation of gel electrophoresis, termed  polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
Capillary Electrophoresis: Applications01:30

Capillary Electrophoresis: Applications

Capillary electrophoretic separations offer various modes, each with unique applications. These modes include capillary zone electrophoresis, capillary gel electrophoresis, capillary array electrophoresis, capillary isoelectric focusing, capillary isotachophoresis, micellar electrokinetic chromatography, and capillary electrochromatography.
Capillary zone electrophoresis (CZE) separates ionic components based on their electrophoretic mobility. It has been used to separate proteins, amino acids,...
Colloids03:22

Colloids

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Summary

Headspace concentrations of aroma chemicals in shampoo systems correlate with the water-to-surfactant ratio, suggesting a simple partitioning model. This research aids in understanding perfume behavior in surfactant-based products.

Area of Science:

  • Physical Chemistry
  • Colloid and Surface Chemistry
  • Analytical Chemistry

Background:

  • Aroma chemical behavior in complex surfactant systems like shampoos is not fully understood.
  • Understanding partitioning is crucial for predicting fragrance release and performance.
  • Sodium dodecyl sulphate (SDS) is a common surfactant in personal care products.

Purpose of the Study:

  • To measure vapor phase concentrations of aroma chemicals above a model shampoo system.
  • To investigate the influence of the medium on perfume profiles.
  • To relate headspace concentrations to partitioning behavior and surfactant system properties.

Main Methods:

  • Headspace gas chromatography (GC) methodology was employed.
  • Measurements were conducted on aroma chemicals in a model shampoo system containing SDS.
  • Comparison studies were performed using aroma chemicals dissolved in water and diethyl phthalate.

Main Results:

  • Headspace concentrations of aroma chemicals were found to be directly proportional to the water/SDS phase volume ratio.
  • A simple partitioning model could rationalize the observed headspace behavior.
  • The octanol/water partition coefficient was identified as a relevant parameter for predicting perfume behavior.
  • Apparent activity coefficients were calculated to account for unknown phase structures.

Conclusions:

  • Simple partitioning explains aroma chemical behavior in SDS surfactant systems.
  • The water/SDS ratio is a key factor influencing headspace concentrations.
  • Further studies using liquid analogues are needed for detailed surfactant/perfume interaction analysis.
