Abstract: Cosmetic compositions, systems and methods for conferring responsive durable shaping of keratinous fibers employ at least one shape memory polymer that includes a four-armed branched polyethylene glycol (PEG) based polymer that is functionalized with one or more metal-coordination active groups. The shape memory polymer forms a crosslinked network coating on a substrate, for example a substrate selected from keratinous substrates, for example, hair. Hair coated with the shape memory polymer and treated with an oxidizing agent can be shaped, locked into shape, and reprogrammed by modulation of pH. The coated hair retains durable shaping properties through at least one shampoo treatment. The cosmetic compositions, systems and methods provide durable and reprogrammable durable shaping of the keratinous substrate, for example for styling hair.

Abstract: The present disclosure relates to thermoresponsive oil-in-water nanoemulsions that include: (a) one or more amphiphilic triblock copolymers; (b) one or more oils in the form of nanoemulsion droplets having an average size of about 20 nm to about 500 nm; (c) about 5 to about 40 wt. % of one or more surfactants; (d) one or more nonionic co¬ surfactants; and (e) water, wherein the nonemulsion undergoes a sol-to-gel transition at about 20° C. to about 50° C. One or more lipophilic active ingredients and/or one or more hydrophilic active ingredients may be incorporated into the nanoemulsions. The nanoemulsions are particularly useful for medical, pharmaceutical, and cosmetic applications.

Abstract: A fluid characterization measuring instrument is disclosed that comprises a sample vessel for a bulk complex sample fluid having a capacity that is substantially larger than a domain size of the complex sample fluid and that is sufficiently large to cause bulk scattering effects to substantially exceed surface effects for the complex fluid sample, a coherent light source positioned to illuminate the bulk complex sample fluid in the sample vessel and a first fibre having a first end positioned to receive backscattered light from the sample after it has interacted with the sample. The first fibre can also be positioned close enough to an optical axis of the coherent light source and to the sample vessel to substantially decrease a contribution of multiply scattered light in the backscattered light.

Abstract: Viscometers and viscometry methods are disclosed. In one general aspect, a fluid is driven through capillary tubes with different inside volumes, and successive images of the fluid are acquired as it advances through the inside volume of the capillary tubes. A range of different viscosity values of the fluid are derived from the successive acquired images, and results of this step are reported in a manner that provides insight into non-Newtonian effects in the fluid. In another general aspect, a viscosity value is selected based on detected pressure levels.
