Method for determining migration quantity of volatile organic compounds in adhesive sticker for food label in water-based food simulating object

ActiveCN103575848AOvercome the disadvantage of not being able to directly enter water samplesHigh detection sensitivityComponent separationWater basedMass spectrometry detector
The invention discloses a method for determining the migration quantity of volatile organic compounds in an adhesive sticker for a food label in a water-based food simulating object. The method comprises the following steps: performing a direct or indirect migration test on the adhesive sticker for the food label through a water-based food simulating solution; sampling the water-based food simulating solution through purging and trapping; separating 10 volatile organic compounds through HP-5ms or chromatographic columns with similar properties; performing detection through a mass spectrometry detector; performing quantification through an external standard method, wherein the 10 volatile organic compounds include nonene, 2-ethylhexanol, 1,2,4,5-tetramethylbenzene, camphor, 1-dodecene, naphthalene, 2-ethylhexyl acrylate, 1-methylnaphthalene, 1-undecanol and dodecyl aldehyde. The method is accurate in test, easy to operate, high in efficiency, quick, high in sensitivity and high in practicality, is applicable to qualitative and quantitative determination on the volatile organic compounds in the adhesive sticker for the food label through a manufacturing enterprise of the adhesive sticker for the food label and relevant government supervision departments, and can be used for avoiding harm to the physical health of a consumer caused by over-large migration quantity of the volatile organic compounds.

Experimental method for simulating oral environment, material for environment, and application of material

The invention discloses an experimental method for simulating an oral environment, a material for the environment, and application of the material. The experimental method comprises: preparing a lactic acid solution and treating a demineralization dentin sample. NACP resin comprises 100 parts of resin containing nano amorphous calcium phosphate, 0.2 part of camphorquinone, and 0.8 part of p-N,N-dimethylamino isoamyl benzoate. The cooperation with a PAMAM solution has the effects of buffering the pH value of the lactic acid solution, releasing calcium phosphate particles and promoting remineralization of the demineralization dentin sample. An extreme oral environment where saliva does not exist totally is simulated, thereby facilitating prevention and treatment of dental caries of a patient suffering from decrease of saliva quantity. The experimental method can be clinically applied to prevention and treatment of the dental caries of the patient suffering from the decrease of the saliva quantity, and is simple in operation and high in feasibility.

Method for preparing modified PBS copolyester by using camphor alcohol

The invention relates to a method for preparing modified PBS copolyester by using (1S, 3R)-(1)-cis-1, 2, 2-trimethylcyclopentane-1, 3-dimethanol (TCDM). PTS polyester, random PBS copolyester and block PBS copolyester are prepared under the conditions of high temperature and high vacuum by using camphoric acid as a raw material and tetrabutyl titanate as a catalyst. The preparation method comprises the following steps: (1) preparing (1S, 3R)-(1)-cis-1, 2, 2-trimethylcyclopentane-1, 3-dimethanol (TCDM) from camphoric acid; 2) preparing PTS polyester from the TCDM; 3) preparing a random PBS copolyester from the TCDM; 4) preparing the block PBS copolyester from PBS and PTS. The method disclosed by the invention has the advantages that the rigid alicyclic diol is extracted from natural camphor and has high reaction activity, rigidity and better thermal stability. Raw materials are wide in source and low in price; the polyester synthesis process is simple, green and environment-friendly, and is beneficial to industrial production; the prepared modified PBS copolyester material is good in thermal stability, structural and functional diversification is easy to realize, and the performance can be comparable with that of polyester based on a petroleum raw material. The polyester material is degradable, does not cause white pollution, and meets the environmental protection requirement.

Therapeutic compositions for the treatment of benigh prostate hyperplasia, prostatitis, impotence, infertility and prostate cancer and a method for the use thereof

InactiveUS20100112102A1Alleviate dynamic componentEffective treatmentBiocideSuppositories deliverySuppositoryVein
Therapeutic compositions are proposed for treating and preventing benign prostatic hyperplasia, prostatitis, impotency, infertility and prostate cancer and to a method for the use thereof. They are based on dextrorotary or levogeratory or racemic camphor in the form of a fatty-oil-dimexide emulsion, an oil-aqueous emulsion, or suppositories, the camphor quantity being of 0.1-15.0% by volume. The compositions are rectally administrable once a day by course of therapy up to 20 days every year. They increase the resistance of tissue colloids, activate the erection center of the parasympathetic nervous system, exhibit M- and H-cholinolytic action, produce tonic action on the ejaculation center, normalize the capillary and venule tonus, stimulate vasomotor centers of the spinal chord, enhance the synthesis of macroergic phosphates, inhibit ATP-acid splitting in the hypoxia conditions and exhibit analgesic, bactericidal and fibrinolytic effect, etc. The compositions and method enable carrying out the preventive treatment of the above-listed disease.
