Problems solved by technology

However, anti-sensitivity products can only be used separately from tooth whitening products, which is a separate solution to the problem of tooth sensitivity. If one or more of the above-mentioned substances are added to the tooth whitening gel formula, it will be damaged during the gel preparation process. In order to solve these difficulties, the cost will be greatly increased, and the actual effect is not ideal, and many users still have toothache and obvious discomfort.

Abstract

The invention discloses a tooth whitening gel containing an anti-allergy agent, the tooth whitening gel comprises solvent water and a pH regulator, and further comprises 1%-50% of an oxidizing agent, 0.1%-10% of a thickening agent and 0.1%-40% of cyclodextrin included anti-allergy agent particles, and the anti-allergy agent is selected from one or more of benzocaine, lidocaine, articaine, dyclonine, tetracaine, ropivacaine and eticaine. The invention also discloses a preparation method of the tooth whitening gel containing the anti-allergic agent. According to the invention, the anti-allergy agent is added into the tooth whitening agent and is clathrated by cyclodextrin, so that the anti-allergy agent is prevented from being oxidized by an oxidizing agent, and the tooth whitening agent has the effect of preventing tooth sensitivity or pain. In the using process, saliva secreted by the oral cavity of a user can decompose cyclodextrin and release the anti-allergy agent in the saliva, the anti-allergy agent is combined with a lipid layer of an oral mucosa at the gingival position, the local anesthesia and analgesia effects are achieved, particularly, stimulation of a high-concentration oxidizing agent to the oral cavity and teeth can be obviously improved, and tooth pain and other discomforts of the user are relieved.

Description

technical field [0001] The invention relates to the technical field of tooth whitening, in particular to a tooth whitening gel and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, tooth whitening has gradually become a basic requirement for people to pursue a high-quality life. High-concentration hydrogen peroxide solution and its products are currently commonly used bleaching agents for tooth whitening in clinics, which can be quickly and safely bleached teeth.
