Description

Technical Field

[0001] This invention relates to the field of skincare technology, specifically to a hand cream made with tung oil and its preparation method. Background Technology

[0002] Hand skin is constantly exposed to the external environment, making it susceptible to dryness, friction, ultraviolet rays, and chemicals (such as detergents), leading to moisture loss, barrier damage, and problems like roughness, cracking, and sensitivity. Therefore, hand cream, as a daily hand care product, needs to possess excellent moisturizing, water-locking, soothing, repairing, and nourishing effects. Most existing hand creams use mineral oil and synthetic esters as base oils, which can temporarily relieve dryness, but their moisturizing effect is poor and lacks the soothing and nourishing properties of natural ingredients. Some hand creams claiming to contain herbal ingredients often use a single room-temperature soaking or short-term heating process for herbal extraction, resulting in insufficient dissolution of effective ingredients (such as volatile oils, flavonoids, and polysaccharides from traditional Chinese medicine). Furthermore, the filtration through ordinary gauze leaves residue particles, which can lead to uneven product texture, poor stability, and negatively impact user experience and efficacy.

[0003] Tung oil is rich in unsaturated fatty acids (such as linoleic acid) and vitamin E, possessing excellent skin permeability and antioxidant properties. However, current applications of tung oil primarily focus on its basic oil properties. How to combine it with traditional Chinese medicine theory to develop multi-functional compound products remains a direction for exploration in this field. For example, patent CN118948724A discloses a method for preparing tung oil hand cream using 12 kinds of traditional Chinese medicine through microwave heating. This formula is extensive and somewhat complex, and the preparation method, involving crushing and microwave heating, easily leads to the inactivation of the medicinal components and product instability. Therefore, there is an urgent need for a hand cream with stable medicinal extracts, a non-sticky texture, and strong moisturizing properties. Summary of the Invention

[0004] The primary objective of this invention is to overcome the shortcomings of existing technologies and provide a *Vernicia fordii* oil hand cream and its preparation method. This hand cream uses a unique *Vernicia fordii* medicinal oil as its core ingredient. By directly using *Vernicia fordii* oil as the extraction agent and employing a multi-stage hot extraction process, the effective components of nine traditional Chinese medicines, including *Schizonepeta tenuifolia*, *Saposhnikovia divaricata*, and *Angelica sinensis*, are fully and stably extracted into the *Vernicia fordii* oil, solving the problem of unstable extracts from traditional Chinese medicines. Furthermore, *Tremella fuciformis* polysaccharide and soybean lecithin are added to the nine medicinal ingredients, addressing the issues of stickiness and insufficient moisturizing properties in traditional Chinese medicine ointments, thus combining the fundamental treatment of traditional Chinese medicine with a modern skincare experience.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: A type of hand cream containing *Vernicia fordii* seed oil comprises the following raw material components: 20-60 parts by weight of *Vernicia fordii* seed oil, 1-8 parts by weight of beeswax, 1-3 parts by weight of emulsified wax, 1-2 parts by weight of *Tremella fuciformis* polysaccharide, and 20-30 parts by weight of purified water; wherein the *Vernicia fordii* seed oil is prepared by the following method: S1: Weigh out the Chinese medicinal materials. The Chinese medicinal materials are in 3 sets. Each set contains 3 parts by weight of each of Schizonepeta tenuifolia, Saposhnikovia divaricata, Angelica sinensis, Alpinia officinarum, Cinnamomum cassia, Citrus reticulata peel, and Ligusticum chuanxiong, and 2 parts by weight of each of Carthamus tinctorius and Osmanthus fragrans. S2: Add the three Chinese medicinal materials to the same amount of tung oil in sequence and extract continuously. After each addition, seal the container and heat it in a 70°C constant temperature water bath for 1 hour. S3: The mixed medicinal oil after continuous extraction is subjected to preliminary filtration and vacuum filtration in sequence to obtain the medicinal oil of *Vernicia fordii*.

[0006] Furthermore, the hand cream is a cream made from the following raw materials in parts by weight: 60 parts of tung oil, 8 parts of beeswax, 1 part of emulsified wax, 20 parts of purified water, and 2 parts of tremella polysaccharide.

[0007] Furthermore, the raw material components also include 0.5-1.5 parts of lecithin nanoparticle solution.

[0008] Furthermore, the hand cream is a paste made from the following raw materials in parts by weight: 20 parts of tung oil, 1 part of beeswax, 3 parts of emulsified wax, 30 parts of purified water, 1 part of tremella polysaccharide, and 1 part of lecithin nanoparticle solution.

[0009] A method for preparing a hand cream containing tung oil includes the following steps: (1) Preparation of oil phase: Melt the tung oil, beeswax and emulsified wax at 75-85℃ and stir evenly; (2) Aqueous phase preparation: Heat purified water to 55-65℃, add Tremella polysaccharide, and stir until completely dissolved; (3) Emulsification: The aqueous phase is slowly added to the oil phase under stirring; (4) Homogenization and cooling: Homogenize the mixed emulsion at a speed of 400-1000 r / min for 10-30 minutes, then stir and cool to room temperature to obtain the hand cream.

[0010] Furthermore, a lecithin nanoparticle solution is added in step (1).

[0011] Furthermore, in steps (3) and (4), the heating of the oil phase is stopped before the aqueous phase is added, and the stirring speed is set to 500-600 r / min, and the resulting product is an ointment.

[0012] Furthermore, the stirring speed is 400 r / min, and the resulting product is a cream.

[0013] The beneficial effects of this implementation plan are as follows: 1. Technological Innovation: The oil of *Vernicia fordii* is used directly as the extractant, and a "multi-stage extraction" process is adopted for direct extraction instead of crushing and mixing. Combined with the purification method of "coarse filtration followed by vacuum filtration", the extraction rate of effective components in the medicinal material is greatly improved, ensuring the clarity and stability of the medicinal oil.

[0014] 2. Synergistic Efficacy: This invention creatively combines tung oil with nine kinds of traditional Chinese medicine, so that the medicinal oil has the antioxidant and barrier repair effects of tung oil as well as the effects of traditional Chinese medicine in promoting blood circulation, removing blood stasis, dispelling wind and cold, and warming the meridians. In addition, soybean lecithin and tremella polysaccharide are added. The addition of tremella polysaccharide enhances the moisturizing and nourishing effect, while soybean lecithin can improve the skin's poor texture and has a significant effect on frostbite, chapped skin, and dryness of the hands.

[0015] 3. Flexible formulation: By adjusting the proportions of oils, waxes, and emulsifiers, as well as the mixing process, two dosage forms can be prepared: moisturizing creams and refreshing ointments, to meet the needs of different seasons and skin types.

[0016] 4. Natural and safe: Contains natural Chinese herbal ingredients, deeply moisturizes the skin, and avoids the use of irritating preservatives such as parabens, making it gentle and non-irritating. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Preparation of *Vernicia fordii* seed oil S1: Weigh out 9g each of Schizonepeta tenuifolia, Saposhnikovia divaricata, Angelica sinensis, Alpinia officinarum, Cinnamomum cassia, Citrus reticulata peel, and Ligusticum chuanxiong, and 6g each of Carthamus tinctorius and Osmanthus fragrans. Divide the ingredients into 3 equal portions.

[0020] S2: Place the three medicinal materials into the same beaker containing sufficient tung oil in sequence, and extract continuously. After each extraction, seal the mouth of the beaker with plastic wrap and heat in a 70℃ water bath for 1 hour.

[0021] S3: After continuous extraction, the mixed medicinal oil is allowed to stand and cool. First, it is initially filtered with a 300-mesh filter bag, and then vacuum filtered using a vacuum pump and a Buchner funnel to obtain clear, transparent medicinal oil with a rich medicinal aroma.

[0022] Example 2: Preparation of a cream-type tung oil hand cream Take 60g of the *Vernicia fordii* oil, 8g of beeswax, and 1g of olive emulsion wax prepared in Example 1 and place them in a beaker. Heat to 80°C to melt, and stir at 400 rpm for 15 minutes until homogeneous, as the oil phase. Separately, take 20g of purified water, heat to 60°C, add 2g of *Tremella fuciformis* polysaccharide, and stir at 400 rpm to dissolve, as the aqueous phase. While maintaining stirring at 400 rpm, slowly pour the aqueous phase into the oil phase at a rate of 12 mL / min, and continue stirring for 15 minutes until the emulsion initially forms. Then, turn off the stirring and allow it to cool naturally to 25°C, stirring slightly every 5 minutes during this period. This yields a cream-type *Vernicia fordii* oil hand cream with a light texture that absorbs quickly after application without any stickiness.

[0023] Example 3: Preparation of ointment-type tung oil hand cream Take 20g of *Vernicia fordii* oil, 1g of beeswax, 3g of olive emulsion wax, and 1g of lecithin nanoparticle solution prepared in Example 1, heat to 75℃ to melt, and stir at 400 rpm for 15 minutes until homogeneous, as the oil phase. Take 30g of purified water, heat to 60℃, add 1g of *Tremella fuciformis* polysaccharide, and stir at 400 rpm to dissolve, as the aqueous phase. Slowly add the aqueous phase to the oil phase at 10mL / min, while simultaneously increasing the stirring speed of the oil phase to 550 rpm and stopping heating. After stirring for 15 minutes to form a homogeneous paste, turn off the stirring, allow it to cool naturally to 25℃, and then fill into containers. The resulting paste-type *Vernicia fordii* oil hand cream has a moisturizing texture, is suitable for use in dry seasons, and has a long-lasting moisturizing effect.

[0024] This invention provides a hand cream made from tung oil and its preparation method. By combining natural ingredients and optimizing the process, the efficacy and quality of the hand cream are improved, while the process is simple and controllable.
