摘要:
A water-dissipatable film forming formulation includes a polymer having at least one water solubilizing or dissipating moiety; an active ingredient or agent; and at least one of a plasticizer or a humectant. The present invention also includes a method for delivering an active agent to the epidermis of a subject. The method includes applying the film forming formulation to a predetermined area of skin.
摘要:
A film product composition that has a refractive index that matches the refractive index of the skin. The composition is made from polymers, polymers plus additives, including plasticizers, which have an average effective or actual refractive index of from 1.4 to 1.6. The refractive index of the composition matches the skin's refractive index, and therefore is helpful at masking skin fissures and imperfections such as wrinkles, cracks, abrasions and the like.
摘要:
A dermal patch having comprising at least two layers wherein at least one layer is a polymer matrix system having an active agent admixed therein. At least one of the layers includes a water-dispersible or water-dissipatable polymer. The dermal patch has an elongation factor of at least 50%.
摘要:
Waterborne latexes are commonly used in a variety of coatings including architectural, industrial, paper, and many others. Many coatings would benefit from an incorporated optical whitening or brightening agent. Most common optical brighteners can not be incorporated directly into a water-based system due to their insufficient solubility in water. This report describes a technique for incorporating optical brighteners directly into a water-based latex system using a mini-emulsion polymerization process. Coatings made from these latexes exhibit significant optical whitening/brightening characteristics which greatly enhance the appearance of the coated substrate.

Disclosed is a low VOC coating additive employing a water-dispersible polymer, a water insoluble plasticizer, cyclohexanedimethanol, and optionally an amphiphilic component. The additive can be added to a coating to improve at least one performance characteristics of the coating, such as, wet-edge time, open time, scrub resistance, wet adhesion, and water resistance.
摘要:
The invention relates to an improved water-based polymer coating composition comprising a polymer resin, water and surfactant. As an improvement over prior water-based polymer coating compositions an anionic and/or nonionic surfactant is present in an amount effective to plasticize the coating formed from the composition. A water-based polymer coating composition of the invention is also substantially free from cosolvents. The invention also relates to a method of coating a substrate and a substrate which has been coated with a coating formulation of the invention.

摘要:
Storage-stable acrylate-functional alkyd resin compositions are disclosed that include an acrylate-functional alkyd resin and a monofunctional mercaptan such as a chain transfer agent. The compositions disclosed exhibit excellent stability on storage, and have utility as binders for coating compositions useful as low VOC, quick dry paints.
摘要:
This invention provides stable waterborne polymer compositions, which are stabilized against gelling, comprising a stable waterborne polymer composition having a Tg of greater than about 0° C. and comprising an acetoacetoxy-type functional polymer, a poly(alkylenimine), and a nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of at least about 17.5. The waterborne polymer compositions of the invention are particularly useful in a variety of adhesive formulations such as pressure sensitive adhesives, laminating adhesives, and the like. Methods of making stable waterborne polymer compositions are also disclosed.
