A process for producing a saccharide fatty acid monoester comprises reacting an immobilized thermostable lipase on a mixture comprising:
(A) one or more of acyl donors selected from saturated and unsaturated fatty acids with 6 to 22 carbon atoms, lower alkyl esters of said fatty acids and glycerol esters of said fatty acids, (B) one or more of saccharides selected from monosaccharides with 5 to 7 carbon atoms, disaccharides composed of hexose, sugar alcohols with 4 to 6 carbon atoms, ethers of monosaccharides with 5 to 7 carbon atoms and monohydric alcohols and ethers of disaccharides composed of hexose and monohydric alcohols, and (C) one or more of alcohols selected from secondary alcohols and tertiary alcohols.
摘要:
A method for preparing a vaccine for dental caries comprises the step of culturing a variant which is obtained by integrating a protein antigen (PAc)-expressing gene into the chromosomal gene of a Streptococcus mutans GS-5 strain to obtain the protein antigen, the protein antigen being produced on the surface of cells of oral Streptococcus mutans or it being extracellularly produced by the microorganism and having a molecular weight ranging from about 170,000 to 220,000. Streptococcus mutans GS-5 (K-3), in which a protein antigen-expressing gene is integrated into the chromosomal gene thereof, has an ability of producing the protein antigen on the surface of the cells or extracellularly. A preventive vaccine composition for dental caries for nasal drops comprises the protein antigen thus produced by the strain: Streptcoccus mutans, the vaccine being intranasally administered. The method makes it possible to enhance the yield of PAc and to simplify processes for purifying PAc. The vaccine composition makes it possible to internally easily absorb the protein antigen, PAc, in high efficiency and it also makes it possible to effectively increase the antibody titer observed after the administration thereof. 1

摘要:
A composition for external application to skin comprises one effective component such as compounds obtained by oxidizing coenzyme A and compound R-SH to dehydrogenate and form S-S bonds. The composition is used as a composition for healing traumas or a cosmetic composition for external application to the skin which have a variety of effects such as activation of dermal cells, promotion of their metabolism and healing of traumas and which, upon applying to the skin, prevent aging of the skin and provide wrinkle-free, smooth, moist and young-looking skin. The composition may have a variety of preparation forms such as a cosmetic cream, a milky lotion, a toilet water, a beauty essence, a pack, an undermakeup, a foundation, a jelly and an ointment.

摘要:
A method of producing microcapsules comprising the steps of: mixing (i) an aqueous dispersion containing a capsule having an wall membrane containing polyvinyl alcohol and an aqueous solution containing 8% to 50% by weight of an electrolyte or electrolytes and (ii) an aldehyde or aldehydes having a solubility in water at 20°C of not more than 10%; and allowing the mixture to react under an acidic condition.
(A) hydrogen peroxide and/or a hydrogen peroxide addition compound such as a percarbonate; and (B) at least one activator which is a nitrogen-containing heterocyclic compound in which a halogen atom is substituted for the hydrogen atom of the secondary amino group or a non-heterocyclic N-halo-hindered amine compound, the hydrolysis constant of the activator being within the range of 1 x 10⁻¹⁰ to 5 x 10⁻⁶ (at 25°C). Examples of the activator include 1-chloro-piperidine, 1-chloro-2-methyl-piperidine, 1-chloro-isonipecotic acid, 1-chloro- -hexamethyleneimine and 1-chloro-ε-caprolactam. The bleaching-detergent composition may also contain the components (A) and (B) together with a surfactant. These compositions exhibit an excellent effect concerning bleaching at low temperature, but hardly affect the colors of colored and patterned clothes.
