Hyaluronic acid-containing composition as well as preparation method and application thereof

Abstract

The invention belongs to the field of daily chemicals, and particularly relates to a hyaluronic acid-containing composition as well as a preparation method and application thereof. The hyaluronic acid-containing composition includes hyaluronic acid, potassium ions, and cetylpyridinium chloride. The three components are compounded to achieve a synergistic effect, so the hyaluronic acid-containing composition has good effects of relieving dentin sensitivity, inhibiting bacteria, diminishing inflammation and repairing oral mucosa, and can reduce the irritation of potassium ions to dental pulp nerves and surrounding tissues of teeth. An oral cavity product prepared from the composition is non-irritant in taste and good in user experience, and has wide application prospects.

Description

technical field

[0001] The invention belongs to the field of daily chemicals, and in particular relates to a hyaluronic acid-containing composition and a preparation method and application thereof. Background technique

[0002] Dentine hypersensitivity (Dentine hypersensitivity) refers to the symptoms of soreness when teeth are stimulated by external temperature, chemical substances or mechanical action. The mechanism of tooth sensitivity is roughly as follows: tooth wear, tooth root exposure and gingival recession make the dentin exposed. Due to the open state of the dentinal tubules, under external stimuli, the liquid in the dentinal tubules moves, mechanically agitating the pulp content, and indirectly stimulating the nerve endings in the pulp, resulting in sensitivity symptoms. The mechanism of action of anti-allergic oral care products is mainly to improve the anti-acid ability of teeth, block dentinal tubules and inhibit the excitability of nerve endings. Among them,...
