摘要:
A system and method for measuring streaming potential, conductivity and permeability of a porous sample, such as a plug of fibrous material, in which a test electrolytic solution, such as a neutral dilute salt solution, is flowed through a flow cell containing the sample. The test solution, and a treatment solution whose effect on the sample is to be measured, are flowed through the flow cell as a series of liquid spurts. The system includes a plurality of solenoid valves which are controlled by a computer in accordance with a software program.

An aqueous hair setting composition having reduced tendency of flaking from the hair containing an alginate hair setting resin and a polymer having in a monomer unit at least one carboxylic acid moiety, said compositions preferably being in the form of an aerosol composition that produces a stable mousse upon delivery from the aerosol container.
摘要:
What is described herein are conditioning/styling tetrapolymers of vinyl caprolactam (VCL), vinylpyrrolidone (VP), dimethylaminopropyl methacrylamide (DMAPMA) and C8-C24 alkyl quaternized dimethylaminopropyl (meth)acrylamide or methacrylic acid quaternized monomers (QDMAPMA), in a defined compositional range. Hair and skin care compositions which include these tetrapolymers exhibit advantageous low tackiness and high humidity resistance.
摘要:
This invention relates to compositions and methods for providing cosmetic and other potential benefits to keratin-containing substrates. The compositions contain at least one naturally-occurring cationic protein with a biological function in a cosmetically acceptable carrier, such that the naturally-occurring cationic protein retains its essential configuration, preserving its biological function, when it is in proximity to a keratin-containing substrate.
