There is provided an apparatus and a method for producing a play compound and the play compound itself which, in one embodiment is a compound which sufficiently fluid to be pliable and is typically cold and slimy to the touch. The apparatus and a method provide a powder and liquid to a user, which can be a non-skilled person and thereby allow the mixing of the powder and liquid together by that person to form the play compound outside of a factory environment whilst ensuring that the play compound which is formed has the desired characteristics. Most typically the user which performs the mixing can be the end user, such as a child, who will play with the compound and so the formation of the play compound forms a new part of the play experience.

A method for preparing stable liquid emulsion forms of plant extract is provided. A plant extract is mixed with a diluent oil as an oil mixture. Heat is applied to the oil mixture until the mixture reaches a threshold viscosity. An emulsifying agent is dispersed in water as an emulsifying solution. The oil mixture and emulsifying solution are mixed together. The mixed oil mixture and emulsifying solution are homogenized as a liquid form of the plant extract.

A two-component polyurethane composition comprising: an aqueous dispersion comprising an emulsion polymer and a specific sulphate and/or sulfonate surfactant, and a water-dispersible polyisocyanate; the emulsion polymer with a weight average molecular weight of 70,000 g/mol or less comprising, by weight based on the weight of the emulsion polymer, greater than 0.25% of structural units of a phosphorous-containing acid monomer and/or salts thereof, greater than 15% of structural units of a hydroxy-functional alkyl (meth)acrylate, structural units of an monoethylenically unsaturated nonionic monomer, and from zero to 10% of structural units of an additional acid monomer and/or salts thereof; and a process of preparing the two-component polyurethane composition.

Some reservoirs have tight oil formations, such as the Changqing reservoir. The surfactant polymer flooding and low tension gas flooding are two potential chemical flooding methods for use in tight oil formations. In these methods, an oil displacement agent, or surfactant, is added. Nonionic surfactants with extended chains (by propylene oxide and ethylene oxide) from dialkyl alcohols or dialkyl amines were tested. A synergistic blend of surfactants was developed between the nonionic surfactants and anionic surfactants that lowers interfacial tension and improves surfactant solubility in water and oil.

The present invention is directed to an ophthalmic emulsion. The emulsion has a unique combination of ingredients that promotes the stability of small oil droplets within the emulsion. The emulsion also includes a mucoadhesive polymer that aid in delivering a lipid to the ocular surface.

The present invention is directed to a lipid-based ophthalmic emulsion. The emulsion has an increased amount of a mucoadhesive galactomannan polymer that promotes a long-lasting protection against desiccation and moisture retention.

An embodiment of a CBD Nano-Emulsion material and process comprises a formulation comprising at least a lecithin or mixed lecithin, one or more carrier oils, and a Vitamin E TPGS from a sunflower version and a soy version. Among either version, the versions may further comprise mixed tocopherols, and still further comprise at least one of; an LCT oil, an olive oil, and a coconut oil. Any one of the versions may further comprise at least one of; sodium benzoate, potassium sorbate, and sorbic acid; and even yet further comprise purified water. Some embodiments may comprise a Vitamin E acetate.

The use of surfactant formulations comprising long-chain alcohols as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.
