Description

Compound essential oil composition with scent inhibiting bacteria and mosquito repellent effect

The invention relates to a compound essential oil composed of a plurality of essential oils, which is uniformly mixed with an emulsifier, a co-solvent and water to form a transparent aqueous solution of oil-in-water and then added a mild antibacterial agent component, thereby becoming a special aroma with bactericidal and antibacterial and mosquito repellent The solution of the effect.

The Chinese herbal medicine heritage in China and the application of Herbs in Europe and America have been used for thousands of years. Modern science has also proven the pharmacological properties of Chinese herbal medicines or vanilla plants. Several vanilla values such as tea trees, Essential oil extracts such as eucalyptus, cinnamon, thyme, lemongrass, rosemary, and patchouli have been scientifically proven to be effective in bactericidal, bacteriostatic and deworming.

At present, many epidemic diseases are spread by droplets and mosquitoes. There are already many antibacterial and antibacterial products on the market. These products can be roughly divided into several kinds of sterilizations such as alcohol, hypochlorous acid water and cationic surfactant. The components of the bacteria are used to achieve the effect of epidemic prevention. Among them, alcohol and hypochlorous acid are short-acting products which will quickly evaporate or convert into water after contact with air. Although the cationic surfactant is relatively long-lasting, the stimulation to the human body is Larger, most of the above products have no pleasant scent and can only sterilize and inhibit bacteria and have no mosquito repellent effect.

Most of the antibacterial products produced by using essential oils need to be diluted with alcohol or emulsifier to achieve the application of essential oil dispersion, producing a uniform liquid of oil-in-water or water-in-oil to make goods, using high concentration of alcohol to make The product is flammable and stored at high temperatures and It is easy to be dangerous when it is close to the fire source. Spraying on the skin will cause the water to volatilize together to cause dryness and discomfort. The product type using emulsifier is mostly milky white liquid. It is easy to cause oil and water separation after standing for a while. The new type can make the diluted essential oil product stable in a transparent and clear liquid state, and will not produce a state of separation of oil and water after the process of standing, and can achieve the effects of bacteriostatic sterilization and mosquito repelling in function.

The invention relates to a composition of a compound essential oil bacteriostatic, comprising: a compound essential oil composed of several plant essential oils; and an emulsifier, wherein the emulsifier is a polyoxyethylene sorbitan fatty acid having a hydrophilic hydrophobic equilibrium value (HLB) greater than 10. Ester nonionic surfactant; a bacteriostatic agent, Chlorhexidine Gluconate enhances the antibacterial effect of the compound essential oil; a co-solvent is a polypropylene glycol lauric ethoxylate having a hydrophilic hydrophobic equilibrium value (HLB) greater than 10. Nonionic surfactant; with water. The mixture can be prepared to form a transparent clear yellowish liquid, which has a special aroma and can be used for bactericidal and antibacterial effects.

The essential oil selection can be formulated according to the preference of the individual's favorite essential oil, but if the antibacterial and anti-mosquito effect is to be achieved, the basic formula formulated by the tea tree oil and the eucalyptus oil is used in the present invention, and then other reactions are added. The essential oil formula required for the fragrance, wherein the tea tree essential oil has the main components of the alcohol structure, such as Terpinen-4-ol and α-Terpineol, which can cause the protein denaturation to destroy the cell membrane and dissolve the lipid to produce antibacterial and bactericidal effect. The overall concentration is 0.75%. Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Haemophilus, Escherichia coli, etc. have good inhibition; Eucalyptus essential oil contains p-menthane 3,8-diol (PMD) component, which is vegetal Mosquito repellent ingredients, the basic formula of the two essential oils formulated into compound essential oils can achieve antibacterial sterilization and mosquito repellent effects.

Among them, the polyoxyethylene sorbitan fatty acid ester can achieve the emulsified essential oil component and become a liquid component of the oil-in-water component. However, when the concentration is too high, it is easy to cause irritation to the skin, so it is necessary to control the skin concentration to be 10% or less to avoid skin. Stimulation, while at low concentrations, it can produce anesthetic effects on nerve endings such as skin and mucous membranes, so it can relieve the itching or pain of mosquito bites. Such ingredients are also commonly found in ointment products with soothing function.

The cosolvent lauryl alcohol nonionic surfactant (polypropylene glycol lauryl polyoxyethylene ether) can maintain the stable and transparent state of the composition, and if only the emulsifier component polyoxyethylene sorbitan fatty acid ester can only make the combined liquid The form is a milky white liquid, and after standing for a few days, the oil and water are separated.

Among them, the bacteriostatic agent Chlorhexidine Gluconate is a safe and mild antibacterial ingredient. It has the effect of killing and inhibiting Gram-positive bacteria, Gram-negative bacteria and fungi. It is often used in surgical cleaning fluids, wound treatment, antibacterial agents. Among the saliva and oral care products, it is a mild and effective antibacterial ingredient, and the regulatory limit in China is 0.05%.

The composition of the invention has excellent killing and inhibiting effects on Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans which are common in life, especially the bacteriostatic time-effect is better than alcohol and hypochlorous acid. The water products perform better. The emulsifiers, cosolvents and bacteriostatic agents used are mild and non-irritating cosmetic additives, which can effectively improve the safe use range of the composition. In addition to the antibacterial safety and effectiveness, the compound essential oil The natural hyalinous fragrance produced by the ingredients has the effect of repelling mosquitoes by containing p-menthane 3,8-diol (PMD).

When blending, the oil phase ingredients must be firstly formulated, taking 100 grams of finished product as an example: compound essential oil components account for 3.3% of the total composition, including: eucalyptus 50%, geranium 5%, tea tree 35%, mint 5%, 藿5% fragrance; blending emulsifier is HLB>10 polyoxyethylene sorbitan fatty acid ester and essential oil ratio of 2.5:1; blending cosolvent HLB>10 polypropylene glycol laurel polyoxyethylene ether nonionic surfactant for total The ratio was 1%; the mild bacteriostatic agent Chlorhexidine Gluconate 250 ppm was added, and the mixture was stirred for 30 minutes by a high-speed mixer, and then mixed with sterile water to a total weight of 100 g and stirred for 60 minutes using a high-speed mixer until the liquid was in a clear transparent amber state.
