Description

Technical Field

[0001] This invention relates to the field of oral care products in the category of daily chemical products, specifically to a concentrated, high-cleaning, refreshing, and brightening colored toothpaste and its preparation method. Background Technology

[0002] In oral care products, toothpaste, as a daily necessity, has evolved towards multi-functionality and personalization, but existing products still have many shortcomings. In terms of cleaning efficacy, most rely on conventional abrasive formulations, making it difficult to effectively remove plaque and extrinsic stains, and potentially damaging tooth enamel due to improper abrasive hardness. Regarding user experience, the taste is monotonous, lacking sufficient cooling comfort, and the breath freshening effect only lasts 1-2 hours, failing to meet long-term needs. In terms of appearance, most are plain-colored creams or pastes, lacking visual appeal and failing to enhance the user experience. In terms of formulation, the concentration is low, with a high proportion of solvents and fillers, resulting in insufficient effective ingredients, requiring large amounts to be dispensed to achieve the desired effect, which is both wasteful and inconvenient.

[0003] A few toothpastes on the market that contain pigments or glitter also have stability defects. Due to the lack of a suitable compound binder and preservative system, they are prone to problems such as layering, pigment deposition, glitter agglomeration, or storage deterioration. Moreover, most of them do not take into account cleaning power and sensory experience, making it difficult to achieve the synergistic unity of "high-efficiency function + visual aesthetics + comfortable use". Summary of the Invention

[0025] Step 3: Add abrasive and surfactant: Add silica (H), hydrated silica, K12, LS-30 and polyethylene glycol in sequence, adjust the stirring speed to 1200-1500 r / min, stir for 20-30 minutes to form a uniform paste matrix;

[0026] Step 4: Add sensory ingredients: Reduce the stirring speed to 500-600 rpm, add the corresponding flavoring, menthol, coloring and glitter, and stir for 10-15 minutes to ensure that the sensory ingredients are evenly dispersed;

[0027] Step 5: Allow to cool down naturally: Let the paste cool down to below 40℃, and check the viscosity; it should have a stringy consistency.

[0028] Step 6, Degassing and Filling: The paste from Step 4 is degassed under vacuum conditions of -0.08 to -0.09 MPa. After degassing, it is filled to obtain the finished toothpaste.

[0029] (III) Beneficial Effects

[0030] Compared with the prior art, the present invention provides a concentrated, high-cleanliness, fresh and bright colored toothpaste and its preparation method, which has the following beneficial effects:

[0031] 1. This concentrated, high-cleaning, refreshing, and brightening colored toothpaste and its preparation method utilize a high proportion of sorbitol (68.81%-69.08%) as the core moisturizing carrier, significantly reducing the proportion of ineffective solvents. This results in a concentrated toothpaste texture, requiring only half the amount of regular toothpaste per application to achieve the desired effect, reducing usage by 30-40%. Simultaneously, it incorporates a composite abrasive system of silica (H) and hydrated silica, which has moderate hardness and strong adsorption capacity. This effectively removes plaque, food debris, and extrinsic pigments, improving cleaning power by 30% compared to regular toothpaste, while avoiding scratching tooth enamel. The addition of sodium fluoride also provides significant anti-cavity effects.

[0032] 2. This concentrated, high-cleanliness, refreshing, and brightening colored toothpaste and its preparation method utilize the synergistic effect of menthol and functional additives to deliver a strong cooling sensation and provide breath freshness for ≥4 hours, meeting users' long-lasting freshness needs. The addition of food-grade safe pigments and glitter creates a golden or emerald green gel-like paste with a vibrant and pleasing appearance, significantly enhancing visual appeal and user experience. Simultaneously, the compounded preservative (sodium benzoate, Sampo DMDMH) and binder (CMC, xanthan gum) system effectively prevents paste separation, pigment deposition, glitter agglomeration, and storage deterioration, exhibiting superior stability compared to existing similar products.

[0033] 3. This concentrated, high-cleanliness, fresh and bright colored toothpaste and its preparation method can achieve differentiation simply by replacing sensory raw materials such as fragrances, pigments, and glitter that do not involve chemical reactions. This makes the core formula and preparation process of the two products completely identical, without the need to adjust the production process. The process is simple and controllable, which can not only meet the consumption preferences of different users, but also reduce the cost of industrial mass production, adapt to the needs of large-scale production, and fill the market gap of concentrated toothpaste that combines "high efficiency, visual appeal, and comfortable use".

[0061] Core Raw Material Function Description

[0062] 1. Friction Cleaning System

[0063] Silica (H) (1.00%): The main abrasive, with a spherical structure and moderate hardness. Physical friction can effectively remove extrinsic pigments such as dental plaque, food debris and tea stains, while avoiding scratching the enamel.

[0064] Hydrated silica (13.63%-13.68%): An auxiliary abrasive, its porous structure enhances the adsorption capacity of fine dirt, improves cleaning efficiency, and at the same time improves the extrudability and formability of the paste.

[0065] 2. Stable thickening system

[0066] Sodium carboxymethyl cellulose (CMC, 0.38%): The main thickener and stabilizer, forming a transparent colloid, increasing the viscosity of the paste, preventing the raw materials from separating, and giving it a smooth extrusion texture.

[0067] Xanthan gum (0.46%): An auxiliary thickener that works synergistically with CMC to enhance the stability and shear resistance of the paste, and improve the crystal-clear and glossy texture of the gel-like paste.

[0068] 3. Surfactant and moisturizing system

[0069] Sodium lauryl sulfate (K12, 2.31%-2.32%): The main surfactant, which reduces the surface tension of water, enables toothpaste to foam quickly, enhances the diffusion of cleaning ingredients, and helps remove grease and dirt.

[0070] LS-30 (1.00%): An auxiliary surfactant that, when combined with K12, optimizes foam structure (delicate and long-lasting), reduces oral mucosal irritation, and improves user comfort.

[0071] Sorbitol (68.81%-69.08%): a core moisturizer and concentrated carrier, preventing toothpaste from losing water and hardening, replacing some ineffective solvents to increase the concentration of active ingredients, and also has a slightly sweet taste to improve the mouthfeel.

[0072] Polyethylene glycol (PEG / PEG-400, 2.91%-2.92%): an auxiliary moisturizer and lubricant, improving the smoothness of the paste, facilitating extrusion, and enhancing the compatibility of raw materials to avoid a grainy feel.

[0073] 4. Flavoring and Preservative System

[0074] Sodium saccharin (0.18%): a sweetener that neutralizes the slight bitterness of raw materials. The dosage meets food-grade safety standards and poses no risk of tooth decay.

[0075] Menthol (0.40%): The core cooling agent, providing an instant cooling sensation, inhibiting the growth of oral bacteria, and prolonging the time of fresh breath.

[0076] Sodium benzoate (0.20%): The main preservative, which inhibits the synthesis of microbial cell walls, prevents toothpaste from deteriorating during storage, and extends the shelf life.

[0077] Sampo DMDMH (0.20%): An auxiliary preservative, which, when combined with sodium benzoate, broadens the antibacterial spectrum and is suitable for formulations with a high proportion of humectants to prevent the growth of microorganisms.

[0078] 5. Sensory modification system (differentiated ingredients)

[0079] Flavorings (Wild Chrysanthemum Flavoring TF70908C 0.80% / Green Tea Flavoring TF70557C 0.40%): impart natural floral or fresh herbal scents, mask off-odors of raw materials, and enhance the sensory experience of fresh breath.

[0080] Pigment (0.0055% lemon yellow / 0.01% fruit green pigment): food-grade visual modifiers that give the paste a golden yellow or emerald green color, with no risk of irritation and enhance its visual appeal.

[0081] Glitter (0.04% silver powder / 0.04% gold powder): A visual decorative agent that is evenly dispersed in the gel to create a silver / gold shimmer effect, enhancing the gloss and improving the product's visual recognition.

[0082] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
