Description

Technical Field

[0001] This invention relates to the field of daily chemical product technology, and more specifically, to a natural transparent aromatherapy soap and its preparation method. Background Technology

[0002] In recent years, scented soaps, as products that combine cleansing, aromatherapy, and aesthetic value, have seen increasing demand in the daily chemical market. However, currently available scented soaps still have the following shortcomings in terms of color schemes, cultural connotations, and functionality: 1. The color scheme is monotonous and lacks cultural depth: Existing scented soaps mostly use synthetic pigments (such as azo and anthraquinone dyes) to create their colors. While these colors are vibrant, they lack a natural texture, and their color designs often deviate from traditional cultural contexts, failing to meet consumers' demands for cultural added value in products. Although color systems such as the "Traditional Chinese Colors" provide rich cultural inspiration for color applications, current technologies have not effectively integrated these traditional color schemes, especially the Zimiao color scheme with its Eastern aesthetic connotations, resulting in insufficient visual appeal and cultural recognition of the products.

[0003] 2. Safety issues related to fragrances and colorants: Synthetic pigments may cause skin sensitivity, and long-term use of artificial fragrances (such as phthalates) also poses potential health risks. Although the application of natural pigments (such as anthocyanins and curcumin) and plant essential oils (such as lavender and tea tree oil) has been studied, their stability in transparent soap bases, color development effects, and synergistic blending techniques with fragrances are still immature, and problems such as fading, layering, or fragrance loss are prone to occur.

[0004] 3. Single functional ingredient Most scented soaps focus only on basic cleansing or simply add a single active ingredient (such as glycerin for moisturizing), failing to achieve multiple benefits through a blend of natural ingredients. Furthermore, traditional transparent soap bases often rely on synthetic surfactants or chemical additives such as propylene glycol, which, while increasing transparency, may damage the skin barrier and affect gentleness.

[0005] Therefore, there is an urgent need for a natural, transparent scented soap and its preparation method to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a natural transparent aromatherapy soap and its preparation method.

[0007] To solve the above problems, the present invention adopts the following technical solution: A natural transparent aromatherapy soap, comprising a natural glycerin transparent soap base, a coloring system, and natural plant essential oils; The color development system is selected from either the purple series composed of grape purple natural liquid food coloring and rose pink natural liquid food coloring, or the cyan series composed of fruit green natural liquid food coloring and sapphire blue natural liquid food coloring.

[0008] As a further aspect of the present invention: the natural glycerin transparent soap base is composed of the following formula: Coconut oil 20%, stearic acid 8.6%, sodium hydroxide 4.9%, purified water 16.6%, glycerin 10%, alcohol 30%, rock sugar 10%.

[0009] As a further aspect of the present invention: the natural plant essential oil is selected from one or more of the following: blackberry essential oil, bay leaf oil, sandalwood essential oil, lemongrass essential oil, lemon essential oil, peppermint essential oil, or strawberry essential oil.

[0011] As a further aspect of the present invention: the natural liquid edible food coloring of grape purple in the purple series is selected from purple sweet potato extract, purple cabbage extract, black goji berry extract or blueberry concentrate.

[0012] As a further aspect of the present invention: the rose powder natural liquid food coloring is selected from red beet root extract, red dragon fruit juice, hibiscus extract or strawberry / raspberry concentrate.

[0013] As a further aspect of the present invention: the fruit-green natural liquid food coloring is selected from spinach juice, matcha powder solution, spirulina extract or wheatgrass juice.

[0014] As a further aspect of the present invention: the sapphire blue natural liquid food coloring is selected from butterfly pea flower infusion, spirulina blue protein extract or gardenia blue extract.

[0015] A method for preparing a natural transparent scented soap includes the following steps: Natural glycerin transparent soap base is heated and melted, and the heating temperature is controlled within 82°C; After the natural glycerin transparent soap base has completely melted, spray alcohol onto the surface of the soap solution to defoam. Once the temperature drops to around 76℃, add the prepared natural plant essential oils. Add natural food coloring to adjust the color, stir well, and pour into the mold when the temperature drops to about 71℃. After standing for 3 hours, unmold and package.

[0016] Compared with the prior art, the advantages of this invention are: This invention optimizes the natural glycerin transparent soap base formula, combines it with natural food colorings based on traditional Chinese color matching, and blends it with plant essential oils to create a visually appealing, gentle, and aromatherapy-enhancing transparent scented soap.

[0026] 2. Implementation ① Place a 500ml beaker on a laboratory electric stove and adjust it to between level 1 and level 2. Gradually add small pieces of natural glycerin transparent soap base and heat to melt it. The temperature should be controlled within 82 degrees Celsius. ② After the soap base has completely melted, spray alcohol onto the surface of the soap solution to defoam. Once the liquid temperature has dropped to around 76 degrees Celsius, add the prepared natural plant essential oils (30% blackberry essential oil, 20% bay leaf oil, 12% sandalwood essential oil, 10% lemongrass essential oil, 12% lemon essential oil, 13% peppermint essential oil, and 3% strawberry essential oil; the total amount after blending is 2% of the soap base weight). Add 8ml of grape purple natural liquid food coloring and 4ml of rose pink natural liquid food coloring later.

[0027] ③When the liquid temperature drops to about 71 degrees Celsius, pour it into the mold, let it stand for 3 hours, then demold and package it.

[0028] Example 2 Preparation of Natural Transparent Scented Soap (Blue Scented Soap) 1. Raw material adjustment Color development system: Fruit green and sapphire blue natural liquid food coloring are mixed at a volume ratio of 1:1.5 (e.g., 1 mL fruit green + 1.5 mL sapphire blue).

[0029] Natural plant essential oils: Only sandalwood essential oil (50%) and lemon essential oil (50%) are used, totaling 1.5% of the soap base weight.

[0030] 2. Preparation steps Similar to the steps in Example 1, cyan pigments are added during color mixing, and finally injected into a square mold for shaping.

[0031] Example 3 Preparation of natural transparent scented soap (optimization of compound essential oil-based scented soap) 1. Adjust parameters The ratio of grape purple to rose pink in the color rendering system was adjusted to 3:1, resulting in a deeper color.

[0032] The essential oil blend ratio has been changed to: 30% bay leaf oil, 20% lemon essential oil, and 50% peppermint essential oil to enhance the refreshing sensation.

[0033] 2. Process Improvement The melting temperature is controlled at 75℃, the injection molding temperature is reduced to 68℃, and the standing time is extended to 4 hours to improve transparency.

[0034] The following is a record table of experimental data based on Examples 1-3:

[0035] Effect description: Example 1: The soap exhibits a transparent, pale blue-green color under visible light, with a fruity and woody aroma. Example 2: Under visible light, it displays a clear blue-green hue and emits a citrus and woody fragrance. Example 3: Under visible light, the color is richer than Example 1, with a significantly cool sensation. All products are highly transparent, bubble-free, and meet natural and environmentally friendly requirements. Their corresponding CMYK color values ​​are all within the range of the "Traditional Chinese Colors" color spectrum.

[0036] It should be noted that in actual production, the pigment ratio (e.g., 2:1 to 3:1 for purple) or the type of essential oil (e.g., single sandalwood essential oil) can be adjusted according to needs, while the other parameters remain unchanged.

[0037] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto.
