Methods of manufacturing a liquid crystal device including depositing a layer of liquid crystal material on a substrate and imprinting a pattern on the layer of liquid crystal material using an imprint template are disclosed. The liquid crystal material can be jet deposited. The imprint template can include surface relief features, Pancharatnam-Berry Phase Effect (PBPE) structures or diffractive structures. The liquid crystal device manufactured by the methods described herein can be used to manipulate light, such as for beam steering, wavefront shaping, separating wavelengths and/or polarizations, and combining different wavelengths and/or polarizations.

Virtual and augmented reality systems and methods

A mixing assembly (10) for use in a semi - continuous process for producing liquid personal care compositions, such as shampoos, includes a main feed tube (12) carrying a base of the composition to be produced, a plurality of injection tubes (14, 16, 18, 20, 22) in selective fluid communication with the main feed tube (12), and an orifice provided in a wall at an end of the main feed tube downstream of the plurality of injection tubes. The wall in which the orifice is provided includes a curved (e.g., semispherical) entry surface on an upstream or inlet side of an orifice, and a curved (e.g., semi - elliptical) exit surface on a downstream or outlet side of the orifice. The orifice may have a rectangular or elliptical shape. By maintaining symmetry of the injection tubes with respect to the orifice, and leveraging delay between introduction of dosed modules and increased viscosity, effective mixing may be achieved with minimal energy.

Semi-continuous feed production of liquid personal care compositions

The present invention relates to variants of a parent alpha-amylase.The present invention also relates to polynucleotides encoding the variants; nucleic acid constructs, vectors, and host cells comprising the polynucleotides; and methods of using the variants.

Method for screening alpha-amylases

According to the present invention there is provided a pearlescent liquid treatment composition suitable for use as a laundry or hard surface cleaning composition comprising a rheology modifier providing a high shear viscosity at 20 sec-land 21°C of from 1500 cps, and a pearlescent agent, said pearlescent agent having DO.99 volume particle size of less than 50 μm, or wherein the difference in refractive index (AN) of the medium in which the perlescent agent is suspensed and the perlescent agent is greater than 0.02.

Liquid treatment composition

The present invention provides lipolytic enzyme variants. Specifically, the present invention provides lipolytic enzyme variants having one or more modifications as compared to a parent lipolytic enzyme having at least one improved property. In addition, the present invention provides compositions comprising a lipolytic enzyme variant of the invention. The present invention also provides methods of cleaning using compositions comprising a lipolytic enzyme variant of the invention.

Compositions and methods comprising a lipolytic enzyme variant

Compositions and methods useful for providing one or more benefits, including a color rejuvenation and/or color maintenance benefit to a fabric are disclosed. The disclosed compositions contain at least one cationic polymer. The methods include providing the disclosed compositions in combination with a source of anionic surfactant. Unit dose and multi-compartment systems are also disclosed.

Compositions and methods for providing a benefit

According to the present invention there is provided a pearlescent unitary dose composition comprising a water-soluble film encapsulating a liquid treatment composition suitable for use as a laundry or hard surface cleaning composition having turbidity of greater than 5 and less than 3000 NTU, said composition comprising a pearlescent agent and from 2% to 15% by weight of the composition of water.

Liquid treatment unitized dose composition

Liquid laundry detergent compositions comprising anionic surfactant, fabric care agent, cationic deposition aid and performance booster are disclosed. The performance booster is chosen such that it will not react with the cationic deposition aid or fabric care agent to form a coacervate and/or to precipitate from solution. Such performance boosters may compensate for reduced cleaning efficacy of anionic surfactants and/or fabric care agents which interact with cationic deposition aids.

Liquid laundry detergent compositions comprising performance boosters

The present composition relates to fabric care compositions comprising an organosiloxane polymer. Methods of using such compositions including contacting a fabric with the composition and rinsing the fabric are also disclosed.
