The hydrophilic–lipophilic balance (HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipohilic portions of the surfactant molecule, as described by Griffin in 1949 and 1954. Other methods have been suggested, notably in 1957 by Davies. WebIn chemistry, hydrophobicity is the physical property of a molecule that is seemingly repelled from a mass of water (known as a hydrophobe ). [1] In contrast, hydrophiles are attracted to water. Hydrophobic molecules tend …

WebHydrophobic interaction chromatography (HIC) separates molecules based on their hydrophobicity. HIC is a useful separation technique for purifying proteins while maintaining biological activity due to the use of conditions and matrices that operate under less denaturing conditions. WebAn IOL material surface may be hydrophilic or hydrophobic, measured by photographing a water droplet placed onto the material surface. The contact angle measures the degrees between the material’s surface and water droplet’s surface[7]. Large contact angles define hydrophobic materials, whereas smaller angles define hydrophilic materials[7].
