Provided are an atomic layer sheet that contains boron and oxygen as framework elements, is networked by nonequilibrium couplings having boron-boron bonds, and has a molar ratio of oxygen to boron (oxygen/boron) of less than 1.5, a laminated sheet containing a plurality of such atomic layer sheets and metal ions between ones of the sheets, and a thermotropic liquid crystal and a lyotropic liquid crystal containing these. In addition, there is provided a method for manufacturing an atomic layer sheet and/or a laminated sheet containing boron and oxygen, the method including: adding MBH, where M represents an alkali metal ion, into a solvent containing an organic solvent in an inert gas atmosphere to prepare a solution; and exposing the solution to an atmosphere containing oxygen.

By operationally mounting a plurality of wafers or plates forming tumblers in an independent, separate, substantially closed container, and cooperatively mounting the plate tumbler container with a cylinder forming member, a unique cylinder lock system is attained which is easily and inexpensively manufactured, as well as quickly and easily re-keyed whenever desired. In the preferred embodiment, all of the plate tumblers which are desired for the particular lock construction are mounted in the substantially closed container, with each plate tumbler having the requisite spring means associated therewith. In addition, the plate tumbler holding container incorporates one aperture for each plate tumbler which allows the slot engaging fin of each tumbler to extend outwardly from the container for locking and unlocking association with the housing.

By combining dihydroxyacetone as the active skin coloring agent in combination found with a blend of dispersion polymers and polyester polymers, an easily employed, self-tanning formulation is realized which produces a long lasting, naturally appearing coloring of the skin without any orange pigmentation being produced. In addition, tan colored skin produced by the present invention maintains the desired color for extended periods of time. In the present invention, the dispersion polymers stabilize the dihydroxyacetone as well as provide a thickening agent for the composition. In addition, the present invention also incorporates an oil soluble polyester polymer in combination with the other ingredients which achieves a formulation which provides a slow release of the active ingredient.

Self-tanning composition

Cosmetic composition comprising cationic thickener prepared in a nonaqueous system in the absence of a surface active agent by polymerizing monomer composition containing 15 to 90% by weight of at least one of acrylic monomer having amino group and methacrylic monomer having amino group, 0 to 80% by weight of vinyl monomer, 1 to 60% by weight of monomer having at least one of acryloyl group and methacryloyl group and 0.1 to 25% by weight of crosslinkable vinyl monomer. This cosmetic composition imparts refreshing feeling and little skin irritation and can be suitably used as hair cream, hair lotion and the like.
