A dentifrice composition stably containing cetylpyridinium chloride and having improved shape retention at a low temperature in the form of an aqueous gel is disclosed. The composition comprises 15 to 80% by weight of a polyoxyethylene-polyoxypropylene block copolymer surfactant based on the total weight of the composition, 0.001 to 5% by weight of cetylpyridinium chloride based on the total weight of the composition, and polyethylene glycol having an average molecular weight of 2,000 to 20,000 in a proportion of 1/200 to 1/4 based on the weight of the polyoxyethylene-polyoxypropylene block copolymer.

摘要:
The present invention relates to a process for producing a pharmaceutical composition which can stably contain an active ingredient unstable against water and can sustained-release such the active ingredient for a long period of time by remaining at an administrated portion as well as a pharmaceutical composition produced by the same. Specifically, the present invention relates to a process for producing a pharmaceutical composition, comprising steps of: mixing and heating a first phase, prepared by mixing a polyhydric alcohol and a salt, and a second phase containing a water-soluble polymer under a reduced pressure, before evaporating substantially all water in the first phase by mixing and heating a mixture of first and second phases under a reduced pressure or after evaporating substantially all water in the first phase by mixing and heating the first phase under a reduced pressure; and adding a third phase containing an active ingredient unstable against water and mixing them to obtain the pharmaceutical composition, as well as a pharmaceutical composition produced the same.
摘要:
A viscous liquid-dispensing container which allows almost all amount of the content thereof to be easily extracted. The container includes a liquid-dispensing section having a head and a shoulder, and inner and outer containers respectively connected with the shoulder. The liquid-dispensing section includes a first check valve for allowing only extraction of the liquid. The outer container includes a second check valve for allowing only introduction of the exterior air. The inner container for accommodating the viscous liquid has a upper sleeve and lower bag connected to the upper sleeve. The upper sleeve is relatively hard, while the lower bag is made of a flexible thin film. After a predetermined amount of liquid is extracted, the lower bag is inverted and invades into the upper sleeve depending on the reduction of the liquid in the inner container.

A method for diagnosing contraction or progress of periodontal diseases is carried and by determining periodontopathic bacteria specific aminopeptidase activity in a specimen by using as a substrate for the enzyme. The substrate is either or both compounds of the formula:X--Z--Arg--Y [1]wherein Arg is arginine residue; X is or an amino blocking group; Y is a color developing group attached to the C-terminal of Arg; and Z is an amino acid or peptide residue composed of 1 or 2 amino acids or their blocked derivatives, the C-terminal of which is attached to the N-terminal of Arg, andX'--Z'--Pro--Y' [2]wherein Pro is proline residue; X' is an amino blocking group; Y' is a color developing group attached to the C-terminal of Pro; and Z' is an amino acid or peptide residue composed of 0 to 4 amino acids or their blocked derivatives, the C-terminal of which is attached to the N-terminal of Pro.
摘要:
Novel durable 2-part hair dyeing agents composed of a first agent comprising as essential components at least one compound that forms HCO.sub.3 --by dissociation in water, an alkali generating substantially no irritating odor and a dye for hair and having a pH of 8.2 to 9.0. and a second agent comprising as essential components hydrogen peroxide and a buffer solution and having a pH of 2.0 to 4.0, the weight ratio of the first agent and the second agent to be mixed being such that the pH of the mixture of the two is in a range of from 6.5 to 7.9. These 2-part hair dyeing agents require only a short dyeing time, create little damage to hair and no irritating or disagreeable odor and have high dyeing effect.
