摘要:
Compositions and methods for the in situ formation of hydrosilylation (addition) cross-linked organosiloxane films are disclosed. The disclosed films are long-lasting, flexible, transfer-resistant, and water-proof. The film-forming compositions generally comprise alkoxy-terminated organosiloxane polymers and a catalyst and are useful for formulating cosmetics and personal care products.
摘要:
An extrusion blow molding process for a filled, liquid crystalline polymer is provided. By the process, molten polymer having improved melt strength, is vertically extruded downward into space through a parison-forming, annular gap. Sag resistant parisons are formed. Beneficially, the parisons may be formed periodically. Advantageously, large-sized parts or structures may be produced.
摘要:
Mechanical properties, especially tensile and flexural properties and impact strength, of glass fiber reinforced oxymethylene polymer molding compositions can be enhanced by incorporating into the molding composition an effective amount of a prepolymeric amino resin, whereby the glass fiber reinforcing agent and the oxymethylene polymer are coupled. The amino resin can be a condensation product of formaldehyde and melamine, urea, guanidine, guanamine or a substituted guanamine. An acid catalyst is preferably employed to promote the cross-linking of the prepolymeric amino resin.

摘要:
A post-application expanding composition for application to hair fibers of the scalp, eyebrows or eyelashes is provided. The composition comprises at least one surfactant, a solvent for the surfactant, and a volatile agent in an amount that will cause the surfactant and solvent to interact and foam on the hair fibers thereby producing an expanded composition. The composition further contains a film-forming agent in an amount effective to form a film which when set fixes at least a portion of the expanded composition in its expanded state. The volatile agent is solubilized in the composition, and is further dispersed throughout the composition in nanometer size droplets or generated in situ on the hair fibers or immediately prior to application thereto so that the composition is storable in a non-pressurized container.
摘要:
Cosmetic compositions comprising a Boger fluid are provided as well as methods for using such compositions in cosmetics that exhibit Boger fluid-like characteristics, such as self-leveling. These cosmetics provide for ease of application and aid in achieving a smooth, even, and/or glossy finish on skin and hair.
摘要:
A hair styling implement is comprised of a support and an extension mounted therefrom. The extension is preferably comprised of at least 75%, more preferably 90% and most preferably is comprised substantially completely of a material able to absorb water by wicking or capillary action. The extension is coil shaped, a die-cut sheet folded to encase at least a part of the support, a plurality of disks or a first series of disks separated from a second series of disks by a plurality of bristles.
摘要:
There is provided a cosmetic or topical composition for use on the human body having a phosphate compound in an amount effective to inhibit corrosion of metallic containers containing the composition. Preferably, such a cosmetic or topical composition has sodium hydrogen phosphates and/or sodium polyphosphates in an amount about 0.05 wt % to about 1.5 wt % based on the total weight of the finished composition.
