Abstract: A pencil barrel is prepared by extruding, shaping, and cooling, under controlled conditions, a foamable, thermoplastic resin-based composition. The combination of the particular extrudable composition and the means of shaping and cooling the tubular extrudate obtained therefrom are readily useful as barrels, i.e. sheaths, for sharpenable pencils, particularly in the cosmetic industry. The resultant pencil barrels are characterized by their sharpenability, uniform satin-matte smoothness, outstanding printability, and their prolonged resistance to atmospheric conditions. The method for making said pencil barrels is also disclosed.

Abstract: A color display facsimile of a cosmetic product comprised of the formulation of an original cosmetic product and prescribed amounts of each of a thermoplastic, copolymeric hardening agent and a hydrocarbonous-based temperature control component. The resultant display facsimile is capable of exhibiting the exact-likeness characteristics of true color, size, and shape of the original cosmetic product. The method for preparing said color display facsimile is also disclosed.

Abstract: A method for the encapsulation of pigment particles utilized in ink formulations by means of vinyl polymerization, within an aqueous medium, and the cosmetic products prepared with said ink formulations are disclosed. The method of encapsulation can be either that of free-radical polymerization, wherein a peroxide catalyst and a antioxidant are employed or that of a redox system wherein an ion-producing metallic pigment is utilized. The resultant cosmetic products are characterized by their overall smoothness, uniform color, and increased dispersibility of the ink formulations utilized therein, and, due to the presence of the ink formulation having the encapsulated pigment particles dispersed therein.

Abstract: Molded cosmetic products, containing a uniform ultra glossy wet look surface finish are molded in polymeric molds or mold inserts whose inner walls have been modified by subjecting them to a plasma treatment. This allows an improved release of the products and imparts the wet look surface finish to the cosmetic products.

Abstract: A colorized, protective lipstick dispenser for dispensing a lipstick bullet.

Abstract: A multiple cavity mold for lipstick products includes a plurality of receptacles. Each receptacle has an inner cavity and an outer surface that is exposed such that a coolant, which is circulated about the receptacle, causes a cosmetic melt contained therein to solidify.

Abstract: A module of a thermoplastic impregnated with a cosmetic color is fabricated using ethylene vinyl acetate (EVA) as the thermoplastic. The module may have an adhesive layer secured to one surface for securing the module to various carrier substrates as cosmetic containers, carrier dispensing layers or the skin of a user for providing a true indication of cosmetic color. The cosmetic color may actually be a sample of the cosmetic being provided or a sample of the color formulation as prepared during the manufacture of the cosmetic.

Abstract: Polymeric molds and polymeric mold inserts which have been modified by a plasma treatment process. These modified molds and mold inserts may be used to manufacture improved molded cosmetic products such as lipsticks, giving these products a uniform high-gloss finish.

Abstract: A decal which is adapted to decorate bottles, containers and similar devices of the type having surfaces with high wetting angles is fabricated without the use of wax. The decal can be printed upon utilizing various inks to provide aesthetic container surfaces as for example utilized in the cosmetic industry. The decal is free of wax and consists of a carrier layer as a plastic or paper having impressed thereon a base and a release layer which typically is a suitable plastic type material. The plastic type material as secured to the base layer has imprinted thereon a suitable pattern employing an ink which can contain metallic pigments or other piggments. The printed pattern has deposited thereon an adhesive layer which is relatively thin and which layer is secured to a desired surface of the container at low temperatures. After securing the decal to the surface of the container the release and base layers are removed thereby leaving the printed matter on the surface of the container.

Abstract: A cosmetic product includes a cosmetic component as a pigment maintained within a matrix of fibrillatable polymer. The pigment and polymer composition provides a cosmetic which can be employed for coloration of the skin and utilized as eye makeup, powder, or other cosmetic products by employing suitable processing techniques such as extrusion, milling, compacting, and so on.

Abstract: A cosmetic product includes a fibrillatable polymer as a binding agent. The thusly prepared composition having said fibrillatable polymer incorporated therein provides a cosmetic product which can be employed for coloration of the skin and utilized as a lipstick, as well as eyeshadow and eyeliner pencils, compressed powders and other solid-type cosmetic products obtained by suitable processing techniques such as milling, extrusion, compacting and so on.

Abstract: A cosmetic product, such as lipstick, is provided with a surface layer having a wetting angle less than the normal wetting angle of the cosmetic product. The surface layer, which can be formed by subjecting the cosmetic product to a plasma treatment process, allows a material having an ultra-glossy finish and having poor adhesion with objects which have a wetting angle in the neighborhood of the normal wetting angle of the cosmetic product to be adhered to the surface layer and hence to the cosmetic product.

Abstract: A prepolymerization step prior to casting reduces shrinkage during polymerization of a composition containing diethylene glycol bis(allyl carbonate) with up to 40% of a vinyl ester, preferably vinyl acetate, and one or more free radical type initiators. The prepolymerization step includes adding a small amount of free radical type initiator, which may be the same or different than that used just prior to casting, and heating to a temperature higher than one hour half-lifetime temperature of the initiator. In this manner, most of the added initiator is consumed and the prepolymerization produces the highest possible conversion while preventing overpolymerization. High yield of lenses of ophthalmic quality is obtained.

Abstract: A continuous process for preparing finely divided thin, bright metal particles which comprises applying a release coating to at least one side of a carrier sheet, depositing a metal film of from 350 to 450 angstroms thickness onto the release coating solubilizing the release coating, removing the metal film from the carrier sheet, and breaking the thin metal film into particles having a diameter of between 25 to 50 microns.

Abstract: A laser beam is used to provide rapid, clear and permanent marking of plastic lenses.

Abstract: A vacuum chuck for use in lens grinding having a vertical bore extending downwardly into the block to join a through horizontal bore provided with a venturi, so that by blowing air through the venturi a vacuum is created in the vertical bore to secure the lens placed on top of the block.
