Problems solved by technology

Melamine resin microcapsules need to add formaldehyde during the preparation process, and there is formaldehyde residue, which cannot be applied to oral care products. Microcapsules with glycol dimethacrylate as the wall material cannot persist in the oral cavity, cannot form bioadhesion with the oral mucosa, and cannot achieve the effect of sustained release

Abstract

The invention provides a method for wrapping peppermint oil microcapsules, which comprises the following steps: preparing an emulsifier solution containing 5-10% of an emulsifier which is a compound of Arabic gum and carbopol in a ratio of 1: 1-5: 1; mixing the emulsifier with the aqueous solution to obtain a water phase; mixing peppermint oil, N-(2-hydroxypropyl) methacrylamide and caprylic/capric triglyceride, and uniformly stirring to obtain an oil phase; adding ammonium persulfate into 30 times of water to prepare an initiator; mixing the water phase and the oil phase to form an emulsion; and introducing nitrogen into the prepared emulsion, adding the prepared initiator after 30-45 minutes, stirring, and reacting at room temperature for 2-4 hours, thereby obtaining the product. According to the peppermint oil microcapsule disclosed by the invention, a material, namely carbopol, with biological adhesion is added and compounded with N-(2-hydroxypropyl) methacrylamide, so that the residual time of the peppermint oil microcapsule in an oral cavity is prolonged, and a slow release effect can be achieved.

Description

technical field [0001] The invention relates to an oral care product, in particular to a wrapping method and application of peppermint oil microcapsules. Background technique [0002] Fresh breath is a basic requirement for consumers to use toothpaste. Commonly used methods for fresh breath include covering breath, adding zinc ions to absorb breath, and reducing the bacteria that cause breath. Among them, adding essence to obtain a good mouthfeel to freshen breath is the most commonly used. As a flavor for refreshing breath, ingredients such as peppermint oil, menthol, WS-3, WS-23 are usually added. Because toothpaste belongs to the dosage form of rinsing, the amount left in the oral cavity after use is very small, so the time to achieve fresh breath by essence is relatively short, usually only 10 minutes. [0003] In order to improve the breath freshening effect of the essence, the present invention relates to a preparation method of peppermint oil microcapsules, which is...
