Description

Technical Field

[0001] The invention relates to the field of daily chemical products, in particular to a peach and cherry-flavored oral care cleanser and a preparation method thereof. Background Art

[0002] With economic development, people's living standards have significantly improved, and health awareness has continued to grow, leading to an increasing emphasis on oral care. Oral health is crucial to people's daily lives, not only directly affecting their comfort in eating and communicating, but also closely linked to their overall physical health. To meet this demand, a wide variety of oral care and cleaning products, such as toothpaste, mouthwash, and oral spray, have emerged on the market. However, these products face numerous challenges in practical application that need to be addressed.

[0003] In terms of flavor, most products are still limited to traditional mint and fruit flavors. Although these classic flavors are well-known, as consumers pursue more personalized and high-quality lifestyles, these flavors are gradually lacking novelty and uniqueness, making it difficult to meet consumers' increasingly diverse taste preferences and provide consumers with a unique sensory experience.

[0004] Regarding the impact on the oral mucosa, some oral care and cleaning products, while achieving their oral cleansing function, can also cause irritation. The oral mucosa is delicate and sensitive, and irritation can cause discomfort such as pain, redness, and swelling, significantly impacting the consumer experience. Fear of irritation may even lead to reduced product use, compromising oral care effectiveness.

[0005] Some oral care products also perform poorly in terms of fragrance retention. One reason people use these products is to keep their mouths fresh for a long time, but some products have a short-lasting fragrance and fail to effectively mask bad breath. This leaves users with bad breath problems after a short time, failing to meet people's need for long-term oral freshness.

[0006] In response to the above-mentioned related technologies, the inventors believe that the oral care and cleaning products currently on the market have shortcomings in terms of fragrance, irritation to the oral mucosa, and lasting fragrance. It is urgent to develop oral care and cleaning products with novel fragrance, mild and non-irritating, and long-lasting fragrance to better meet consumers' pursuit of oral health and high-quality life. Summary of the Invention

[0007] In order to solve the technical defects of the prior art, the present application provides a peach and cherry flavored oral care cleanser and a preparation method thereof.

[0008] In the first aspect, the present application provides a peach and cherry flavored oral care cleanser, which adopts the following technical solution: A peach and cherry flavored oral care cleanser, comprising, by mass percentage: Antibacterial agent 5-10%, synthetic menthol 10-50%, polyol solvent 10-50%, linalool 1-5%, methyl dihydrojasmonate 1-5%, fixative 1-5%, Asian mint oil 1-5%, anethole 1-5%, gamma-decanolide 0.1-1%, rose oxide 0.1-1%, raspberry ketone 0.1-1%.

[0009] By adopting the above technical solutions, a three-stage compound fragrance of "fruity-floral-herbal" is created, which is fresh and unique; the polyol solvent slowly releases the fragrance, and the fragrance lasts for more than 4 hours; the low-irritation antibacterial agent is combined with moisturizing ingredients, with a neutral pH, gentle cleansing and high safety, taking into account both sensory experience and oral health.

[0010] Preferably, the antibacterial agent is benzyl alcohol.

[0011] By adopting the above technical solution, the preferred benzyl alcohol has a good antibacterial effect and a certain aromatic smell, which can be well integrated into the herbal and refreshing base fragrance.

[0012] Preferably, the polyol solvent is propylene glycol.

[0013] By adopting the above technical solution, propylene glycol is preferably used as a solvent carrier. On the one hand, propylene glycol can dissolve oil-soluble fragrances (esters, ethers, alcohols) to form a stable system; on the other hand, its hydrophilicity combines with oral saliva to slowly release fragrance molecules and prolong the fragrance.

[0014] Preferably, the fixative is benzyl salicylate.

[0015] By adopting the above technical solution, preferably using benzyl salicylate as a fixative, the persistence of fruity and floral fragrances can be well enhanced, and the fragrance system can be well regulated.

[0016] Preferably, the oral care cleanser further comprises 0.1-1% by mass of Italian lemon oil.

[0017] By adopting the above technical solution, adding Italian lemon oil can enhance the freshness of peach fruit and improve the subjective experience.

[0018] In a second aspect, the present application provides a method for preparing a peach and cherry flavored oral care cleanser, which adopts the following technical solution: S1: Weigh the raw materials of each component according to the proportion of each component in the formula; S2: Add propylene glycol to the reactor, turn on the stirring device, set the stirring speed to 100-150 rpm, gradually add benzyl alcohol and synthetic menthol during the stirring process, and continue stirring for 15-20 minutes; S3: Add linalool, methyl dihydrojasmonate, benzyl salicylate, Asian mint oil, anethole, gamma-decanolide, rose oxide, raspberry ketone and other fragrance ingredients in sequence and stir to mix evenly; S4: homogenizing the mixed materials; S5: Perform quality inspection on the homogenized material, and obtain the oral care cleanser if the quality is qualified.

[0019] By adopting the above technical solution, each component is accurately weighed in proportion to ensure the stability of the formula. Propylene glycol first dissolves the antibacterial and cooling ingredients to form a base, and spices are added step by step and stirred to ensure that the "fruit-flower-herb" flavor is evenly layered. The homogenization treatment enhances the fineness of the system and the encapsulation of the spices, achieving sustained release and lasting fragrance. Quality inspection ensures mildness and safety. Finally, the result is an oral care cleanser with distinct fragrance layers, long-lasting fragrance, and clean and mild taste.

[0020] Preferably, after adding each flavor ingredient in step S3, stirring is continued for 3 minutes, and the next flavor is added after it is fully dispersed.

[0021] By adopting the above technical solution, spices can be mixed more evenly, and agglomeration and stratification that affect usage can be prevented.

[0022] Preferably, By adopting the above technical solution, the homogenization effect can be guaranteed and the product is more delicate.

[0023] In summary, this application has the following beneficial effects: 1. Create a three-stage compound fragrance of "fruity-floral-herbal", which is fresh and unique; the polyol solvent slowly releases the fragrance, and the fragrance lasts for more than 4 hours; the low-irritation antibacterial agent is combined with moisturizing ingredients, with a neutral pH, gentle cleansing and high safety, taking into account both sensory experience and oral health.

[0024] 2. The preparation process is simple and efficient, and can stably achieve gradient release of fragrance molecules. DETAILED DESCRIPTION

[0025] The present application is further described in detail below with reference to the embodiments.

[0026] The invention provides a peach and cherry blossom flavored oral care cleanser. The oral care cleanser comprises benzyl alcohol, synthetic menthol, propylene glycol, linalool, methyl dihydrojasmonate, benzyl salicylate, Asian mint oil, anethole, Italian lemon oil, gamma-decanolide, rose oxide, and raspberry ketone.

[0027] After multiple trials, the oral care cleanser of the present invention has developed a unique, complex aroma profile suitable for oral care cleansers: a "fruity top note, floral middle note, and refreshing herbal base note." Specifically, the oral care cleanser of the present invention utilizes γ-decanolide, raspberry ketone, and Italian lemon oil to create a fast-evaporating peach-like top note. γ-decanolide and raspberry ketone contribute to the fresh peach sweetness of the top note, while the Italian lemon oil enhances the freshness of the fruit.

[0028] The oral care cleanser of the present invention constructs a mid-volatile, middle-tone fragrance of cherry blossoms through linalool, methyl dihydrojasmonate, and rose oxide. Methyl dihydrojasmonate and rose oxide construct a sweet and subtle fragrance of cherry blossoms, and linalool enhances the natural feeling of cherry blossoms.

[0029] The oral care cleanser of the present invention uses anethole, synthetic menthol, and Asian peppermint oil to create a herbal, refreshing, slow-evaporating aftertaste. The synthetic menthol and Asian peppermint oil can also enhance the user's subjective cooling sensation, improving the user experience.

[0030] In order to ensure that the above-mentioned unique composite fragrance does not change after being made into an oral care cleanser, while ensuring the effects of gentle cleaning and long-lasting fragrance, the applicant conducted a large number of experiments and finally selected other components in the oral care cleanser.

[0031] The present invention selects propylene glycol among polyols as the solvent carrier. On the one hand, propylene glycol can dissolve oil-soluble fragrances (esters, ethers, alcohols) to form a stable system; on the other hand, its hydrophilicity combines with oral saliva to slowly release fragrance molecules and prolong the fragrance.

[0032] The present invention also uses benzyl alcohol as an antibacterial agent, which not only has good antibacterial effects but also has a certain aromatic smell that can be well integrated into the herbal and refreshing base fragrance. In addition, synthetic menthol and Asian mint oil also have certain antibacterial effects.
