The invention discloses a phosphoric-acid-base modified polycarboxylic-acid water reducer with high adaptability and a preparation method thereof. The water reducer is prepared from the following raw materials: isopentenol polyoxyethylene ether, hydrogen peroxide, acrylic acid, an unsaturated phosphoric acid monomer, deionized water, a reducing agent, and a chain transferring agent. The chain transferring agent is one of mercaptoethanol, mercaptoacetic acid and mercaptopropionic acid. The unsaturated phosphoric acid monomer is prepared from 2-phosphono-1,2,4-butanetricarboxylic acid, p-toluenesulfonic acid and hydroquinone. The preparation method for the water reducer comprises adding isopentenol polyoxyethylene ether and deionized water into a reaction vessel, uniformly stirring, heating, keeping warm, adding oxygen peroxide, then dropwise adding a material solution by employing a constant-flow pump, continuing to keep warm for reacting for 1-1.5 h after dropwise adding of the material solution is finished, naturally cooling to room temperature, and adjusting the pH value of the obtained product to 5-6 by using an alkaline solution. The phosphoric-acid-base modified polycarboxylic-acid water reducer possesses good sulfate ion resisting capability and sludge resisting capability, thereby satisfying engineering demand.

The invention discloses an anti-allergy toothpaste. The anti-allergy toothpaste comprises a potassium salt anti-allergy component, surfactant, moisturizer, friction agent and thickener, wherein the mass percent of the potassium salt anti-allergy component in the toothpaste is 5-10%; and the surfactant is a mixture of at least one of amino acid surfactant and amphoteric surfactant and lauryl sodium sulfate. The toothpaste disclosed by the invention is free of preservative agent; all the components achieve a combined action; the prepared paste is favorable in anti-allergy effect, high in brightness and smoothness and excellent in stability; and meanwhile, foam is not inhibited by the high salt content, and abundant foam can be formed quickly, thereby producing a smooth mouthfeel.

The invention discloses a compound toothpaste with functions of antisepsis, anti-inflammation, acid prevention and desensitization, and a preparation method of the compound toothpaste. The invention adopts natural propolis and traditional Chinese medicine with functions of analgesia, anesthesia and antiallergic effect as main effective preparations, is compounded with the traditional western medicine and is supplemented by biotechnology, so that the compound toothpaste with the functions of antisepsis, anti-inflammation, acid prevention and desensitization can be prepared. The compound toothpaste can be used for preventing and treating periodontitis, dental ulcer, enamel trauma, toothache and sensitivity of teeth, and is also capable of enhancing the self repairing capability of oral cavity tissue, enabling the gum to be healthy, improving the microcirculation, guaranteeing the oral cavity to be healthy and improving the comprehensive antiallergic capability of teeth.

The invention discloses a Japanese saussurea herb extracting solution as well as a preparation method and application thereof. The Japanese saussurea herb extracting solution prepared in a water extract manner is obtained by a lot of experiments and researches of the inventor. The Japanese saussurea herb extracting solution has the characteristic that skin contact anaphylaxis is significantly removed, so that cosmetics containing the Japanese saussurea herb extracting solution have good action on people with sensitive skin, and the using effects of the cosmetics on people with sensitive skin are improved.

The invention discloses a high-salinity composition having functions of resisting dentine hypersensitivity and whitening. The composition comprises the following components in parts by weight: 4-8 parts of potassium nitrate, 0.1-5 parts of pyrophosphate and 3-5 parts of auxiliary sensitivity resisting ingredient; the invention further discloses application of the high-salinity composition in a toothpaste, a tooth powder, a tooth gel, a tooth paste or a cream preparation; the invention further discloses a toothpaste comprising the high-salinity composition, and the weight percentage of the high-salinity composition in the whole toothpaste is 7-18%; the invention further discloses a preparation method of the toothpaste: a humectant is added in a container, then a thickener is added to stir evenly, a sweetening agent, a preservative and a surfactant are added to be stirred evenly, the high-salinity composition is added and stirred evenly, an abrasive and water are added, a fragrance modifier is added after stirring evenly, and the mixture is fully stirred and degassed in vacuum to complete the preparation of the toothpaste. The high-salinity composition and the toothpaste have excellent double effects of whitening and resisting hypersensitivity, the components work synergistically, and the effect is more remarkable.
