Description

Technical Field

[0001] This invention relates to the field of daily chemical technology, specifically to a method for preparing an oral care toothpaste containing cuttlebone powder and salt powder. Background Technology

[0002] Oral care toothpaste is a type of daily chemical product whose core functions are to clean the mouth, prevent oral diseases, and improve oral health. It is essentially an oil-in-water (O / W) or water-in-oil (W / O) emulsion dispersion system.

[0003] Existing oral care toothpastes primarily focus on cleaning, offering limited comprehensive care for sensitive gums, mild oral mucosal discomfort, and fresh breath. This can negatively impact user experience and increase oral care costs. Cuttlebone powder, containing calcium carbonate and other components, acts as a gentle abrasive, helping to clean tooth surfaces with minimal damage to enamel. Salt powder possesses antibacterial, soothing, and breath-freshening properties. Combining these two ingredients in toothpaste can enhance overall oral care, thus creating a need for an oral care toothpaste containing both cuttlebone powder and salt powder. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a method for preparing an oral care toothpaste containing cuttlebone powder and salt powder. By using cuttlebone powder as a mild abrasive, it can effectively clean the tooth surface and reduce wear on tooth enamel. The salt powder works synergistically to inhibit bacteria, protect gums, and freshen breath. The combination of the two solves the problem of limited comprehensive care effects for sensitive gums, mild oral mucosal discomfort, and fresh breath.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a method for preparing an oral care toothpaste containing cuttlebone powder and salt powder, wherein the raw materials by weight percentage are: cuttlebone powder (1%–15%), salt powder (0.1%–0.5%), humectant (20%–45%), abrasive (10%–50%), thickener (0.3%–2%), foaming agent (0.5%–3%), fragrance (0.1%–1%), preservative (0.05%–0.5%), and deionized water (balance). The raw material pretreatment equipment includes: a high-speed pulverizer, a vibrating screen, an electric heating drying oven, and a batching scale; the mixing and dispersing equipment includes: a batching kettle and a high-speed dispersion tank; the homogenization and stabilization core equipment includes: a high-pressure homogenizer and a vacuum degassing kettle; the filling and packaging equipment includes: a vacuum filling machine, a toothpaste tube pressing machine, a labeling machine, and an inkjet printer; and the auxiliary equipment includes: a pH meter and a transfer pump. The method includes the following steps: (1) Raw material pretreatment: Cuttlebone powder needs to be pre-dispersed in a high-speed pulverizer for 2-3 minutes to remove small lumps and ensure uniform friction particles; then add 50g of glycerin for pre-wetting, and the salt powder needs to be dried in a 60℃ oven for 1 hour, cooled and passed through a 100-mesh sieve; then add 30g of sorbitol for premixing, CMC and xanthan gum are mixed in proportion, and 100g of glycerin is added for pre-dissolution.

[0006] (2) Preparation of aqueous gel: Add deionized water preheated to 45°C to the mixing tank, turn on low speed stirring (300r / min), slowly add pre-dissolved thickener mixture, stir for 10min until completely dissolved, forming a transparent and viscous hydrogel; then add xylitol and preservative, continue stirring for 5min until dissolved, and control the system temperature ≤50°C.

[0007] (3) Functional powder pre-dispersion: Add the remaining glycerin + sorbitol mixed humectant to the dispersion tank, turn on high speed stirring (1000r / min), first add the pre-wetted cuttlebone powder, stir for 8min until uniformly dispersed; then add the pre-mixed salt powder, continue stirring for 5min to form a stable powder-liquid mixture system; finally add SDS and peppermint flavoring, stir for 3min until emulsified uniformly.

[0008] (4) Main mixing and homogenization: The functional powder mixing system is slowly pumped into the aqueous gel mixing tank, the stirring speed is increased to 1200r / min, and the mixture is stirred for 15min to fully integrate the two phases and initially form a paste system. The paste material is then pumped into a high-pressure homogenizer and sheared and dispersed under a pressure of 25~30MPa to break up the powder agglomerates and ensure that the cuttlebone powder and salt powder are evenly suspended. The homogenization time is 10min.

[0009] (5) Vacuum degassing and pH adjustment: After homogenization, the material is transferred to a vacuum degassing kettle, vacuumed to -0.09MPa, and degassed at low speed (200r / min) for 15min to remove air bubbles from the material and prevent voids and stratification after filling. The pH of the system is tested and adjusted to 7.0~7.5 with citric acid or sodium hydroxide.

[0010] (6) Vacuum filling and packaging: The degassed paste is transferred into the filling machine under vacuum to avoid secondary foaming; it is filled into toothpaste tubes according to specifications, and after tail pressing, labeling and coding, the finished product is packaged. The finished product must be stored in a cool and dry place below 25℃.

[0011] The salt powder is one of the following: edible salt powder, sea salt powder, or low-sodium salt powder. The salt powder must also be ultra-finely ground, with the particle size controlled at 5-20 micrometers.

[0012] The particle size of the cuttlebone powder is controlled between 5 and 20 micrometers.

[0013] The conventional toothpaste base includes at least three of the following: abrasive, humectant, thickener, foaming agent, fragrance, preservative, and deionized water.

[0014] The toothpaste can be in paste or gel form.

[0015] (III) Beneficial Effects This invention provides a method for preparing an oral care toothpaste containing cuttlebone powder and salt powder, which has the following beneficial effects: The toothpaste prepared by this invention, by setting cuttlebone powder as a mild abrasive, can effectively clean the tooth surface and reduce the wear of tooth enamel; the salt powder works synergistically to inhibit bacteria, protect gums, and freshen breath. The combination of the two solves the problem of limited comprehensive care effects for sensitive gums, mild discomfort of oral mucosa, and fresh breath. Detailed Implementation
