The TI-NatSurff[R]'s offer superb hydrophobe compatibility, and fragrance solubalization without impeding foam.
5, pure and core-shell nanofibers had the same water contact angle, which was about 130[degrees] since PLGA was hydrophobe.
fabricated the superhydrophobic coating through direct mixing of colloidal silica particles (10-20 nm) with sol-gel derived silica binder and the hydrophobe (heptadecafluoro-1,1,2,2-tetrahydrodecyl) triethoxysilane.
Moreover, says Dow Corning, the alkyl functionality of Z-6173 acts as a hydrophobe to reduce water absorption.
This can be explained by the fact that as the CMC is exceeded, each polymer hydrophobe becomes individually solubilized by a single micelle.

The three primary components of the foam control product--a carrier media to assist in spreading, hydrophobic components/ activating agents to assist in rupturing the bubble walls and prevent reformation, and emulsifiers/dispersants to facilitate hydrophobe dispersion and displace bubble-stabilizing surfactants--drive these actions.
Anionic Surfactants : Anionic surfactants are produced by sulfonation and sulphating and, in both cases, a negatively charged sulphur trioxide (SO3) group is added to the hydrophobe.
However, it has now been shown that improved post-shampoo detangling times are achieved by including a small degree of hydrophobic substitution in the cationic guar derivatives, (5)''The hydrophobe is added by the well-known ring opening of the appropriate glycidyl ether.
These studies have shown that the inner cavity of a cyclodextrin molecule has a capping effect on the hydrophobe moieties of thickeners, reducing the network strength of linked polymers and lowering the viscosity of the solution.
