Description

Technical Field

[0001] This invention relates to the field of oral care technology, specifically to oral care compositions and their preparation methods. Background Technology

[0002] Dental plaque is dirt that adheres to the crown, neck, and interdental spaces of teeth. Accumulated plaque erodes enamel, leading to oral diseases. Toothpaste, used with a toothbrush, is a daily necessity for cleaning teeth and protecting oral hygiene; it is safe for human health. With increasing health awareness, various toothpaste products with functions such as hemostasis, cavity prevention, hypoallergenic properties, and antibacterial and anti-inflammatory effects are gaining popularity.

[0003] However, the various types of toothpaste currently on the market have limited functions and do not achieve ideal results in cleaning and caring for the oral cavity, especially teeth. While regular toothpaste does clean teeth, it contains a variety of chemical ingredients, which can be harmful to human health with long-term use and do not provide any auxiliary health benefits.

[0020] Figure 1 This is a process flow diagram of the present invention. Detailed Implementation

[0021] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the present invention discloses an oral care composition, which comprises the following raw materials by weight: 10-30 parts of abrasive, 15-40 parts of moisturizer, 3-10 parts of foaming agent, 5-10 parts of traditional Chinese medicine extract, 2-8 parts of aromatic plant extract, and the balance being deionized water; the traditional Chinese medicine extract includes extracts of honeysuckle, chrysanthemum, Panax notoginseng, Zanthoxylum nitidum, and gallnut.

[0023] Honeysuckle extract contains chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, isochlorogenic acid-A, caffeic acid, luteolin, and quercetin, which have good anti-inflammatory and antibacterial effects.

[0024] Chrysanthemum volatile oil has anti-inflammatory and antibacterial effects. Diluted volatile oil has a significant inhibitory effect on Staphylococcus aureus, Corynebacterium diphtheriae, Mycobacterium tuberculosis, Escherichia coli, and Candida albicans.

[0025] Panax notoginseng has the effects of removing blood stasis and stopping bleeding, promoting blood circulation and relieving pain. Panax notoginseng and some flavonoids are the active ingredients for stopping bleeding, while the active ingredients for promoting blood circulation, removing blood stasis and antithrombosis are notoginsenosides.

[0026] Zanthoxylum nitidum has the effects of dispelling wind, clearing the meridians, reducing swelling and relieving pain. The lignan compound crystal-8 that can be extracted from Zanthoxylum nitidum has a significant analgesic effect.

[0027] Gallnut contains various alkaloids, tannins, and volatile oils. Alkaloids have anti-inflammatory, analgesic, and mild local anesthetic effects, used to reduce the sensitivity of nerve endings in dentin and dental pulp. Tannins have a strong astringent effect, which can coagulate proteins in dentinal tubules, gradually closing the dentinal tubules, paralyzing nerve endings, and relieving pain. Volatile oils have mild analgesic, nerve-paralyzing, and anti-inflammatory effects.

[0028] The abrasive is selected from one of silica, calcium carbonate, and dicalcium phosphate. It is used to remove dental plaque and food debris while avoiding excessive wear on tooth enamel, thus ensuring gentle oral cleaning.

[0029] The moisturizer is selected from sorbitol, glycerin, and polyethylene glycol to maintain the moist texture of the composition, prevent dry mouth during use, and form a moisturizing film on the oral mucosa to relieve oral dryness and discomfort.

[0030] The foaming agent is selected from sodium lauryl sulfate, sodium dodecyl sulfate, and sodium lauroyl sarcosinate. When used in the composition, it can quickly produce rich and fine foam in the oral cavity, evenly covering all parts of the oral cavity, improving cleaning efficiency, and allowing the cleaning ingredients to fully contact the teeth, gums and oral mucosa to exert a cleaning effect.

[0031] The herbal extract is a mixture of extracts of honeysuckle, chrysanthemum, Panax notoginseng, Zanthoxylum nitidum, and gallnut in a weight ratio of 2:2:1:2:1.

[0032] The aromatic plant extracts are selected from one of the following: peppermint, jasmine, grapefruit peel, rosemary, and lemon. They are used to mask bad breath, help freshen breath, and enhance the user's oral freshness experience.

[0033] This invention also discloses a method for preparing an oral care composition, comprising the following steps: Step 1: Preparation of Chinese herbal extract: Take honeysuckle, chrysanthemum, Panax notoginseng, Zanthoxylum nitidum and gallnut according to the weight ratio, screen and wash them, add them to purified water, and use water extraction method to repeat 1-2 times to obtain extract.
