Abstract
Description
Technical Field
[0001] The present invention relates to the field of disinfectants, and particularly to a skin disinfectant containing a disinfection and hemostasis composition and a preparation method thereof. Background Art
[0002] In recent years, people have paid more and more attention to protective measures such as sterilization and disinfection in daily life. Some disinfectant products for human skin, such as hand sanitizers, have emerged as the times require. Therefore, a composition with disinfection and hemostasis functions also has good application prospects in skin disinfectants.
[0003] Although adding a disinfection and hemostasis composition to a skin disinfectant can play a good role in sterilization and disinfection and promote the rapid healing of wounds, the skin disinfectant still has some higher requirements when used on human skin. For example, the skin disinfectant should have good mildness, which is particularly important for some people with sensitive skin. And for convenient and long-term storage, the skin disinfectant should also have good stability and emulsifying suspension ability to reduce adverse phenomena such as freeze-thaw when the temperature changes between high and low.
[0004] Patent CN 113599284B discloses a highly efficient and stable hand sanitizer and a preparation method thereof. The hand sanitizer includes a surfactant, an antibacterial agent, a thickener, a softener, a pH regulator, silicone oil and deionized water, and has a wide and efficient sterilization and disinfection effect, and can also effectively protect the skin and keep it moist and eliminate static electricity. However, the thickeners selected in this application include one or more of hydroxycellulose, carbomer, xanthan gum, hyaluronic acid, and carrageenan. Among them, xanthan gum is preferably used as the thickener in the examples. However, the dispersibility and high-temperature resistance of xanthan gum need to be improved, which may lead to poor stability of the hand sanitizer.
[0005] Therefore, there is an urgent need in the market for a skin disinfectant containing a disinfection and hemostasis composition with good mildness and stability. Summary of the Invention
[0006] Aiming at the problems existing in the prior art, the present invention synthesizes a skin disinfectant containing a disinfection and hemostasis composition from raw materials such as anhydrous ethanol, a disinfection and hemostasis composition, modified xanthan gum, a composite surfactant, etc., which has good mildness, stability and disinfection and hemostasis functions.
[0007] In order to achieve the above object, the technical solutions adopted by the present invention are as follows:
[0008] On the one hand, the present invention provides a skin disinfectant containing a disinfection and hemostasis composition, and the skin disinfectant comprises the following raw materials: 60-80 parts of absolute ethanol, 15-25 parts of the disinfection and hemostasis composition, 0.5-3 parts of modified xanthan gum, 2-6 parts of a softening agent, 10-20 parts of a composite surfactant, and 20-30 parts of deionized water, wherein the composite surfactant is a mixture of dodecenyl succinic acid glucose ester and fatty alcohol polyoxyethylene ether sulfate.
[0009] Preferably, the mass ratio of the dodecenyl succinic acid glucose ester to the fatty alcohol polyoxyethylene ether sulfate is 1:(0.5-0.8).
[0010] In some embodiments of the present invention, by weight parts, each part of the disinfection and hemostasis composition comprises the following raw materials: 30-50 parts of a composite antibacterial disinfectant, 1-5 parts of hydrogenated castor oil, 1-3 parts of Codonopsis pilosula, and 2-8 parts of a hemostatic traditional Chinese medicine component.
[0011] In some embodiments of the present invention, the composite antibacterial disinfectant is a mixture of triclosan and modified chitosan, and the mass ratio is 1:(1.5-2.5).
[0012] In some embodiments of the present invention, the preparation method of the modified chitosan comprises the following steps:
[0013] (1) Adding chitosan into an aqueous hydrochloric acid solution, stirring, adding absolute ethanol for precipitation, subjecting the precipitate to reduced-pressure suction filtration, washing, and drying to obtain chitosan hydrochloride for standby;
[0014] (2) Adding the chitosan hydrochloride obtained in step (1) into deionized water, stirring and then adding it into liquid paraffin, stirring at 50-60°C for 20-40 min, adding glutaraldehyde, stirring, washing, centrifuging, and drying to obtain chitosan hydrochloride microspheres for standby;
[0015] (3) Adding the chitosan hydrochloride microspheres obtained in step (2) into deionized water, stirring, adding dicyandiamide, heating to 120-140°C, stirring, cooling, subjecting to reduced-pressure distillation, precipitating the filtrate with absolute ethanol, washing, suction filtering, purifying, drying, and grinding the precipitate to obtain a product for standby;
[0016] (4) Mixing soy protein isolate powder and the product obtained in step (3), and ball milling to obtain modified chitosan.
[0017] Wherein, in step (2), the mass ratio of chitosan hydrochloride to glutaraldehyde is 1:(0.2-0.5); in step (3), the mass ratio of chitosan hydrochloride microspheres to dicyandiamide is 1:(0.3-0.7); in step (4), the mass ratio of the product to soy protein isolate powder is 1:(0.4-0.7).
[0018] In some embodiments of the present invention, the hemostatic traditional Chinese medicine component is a composition of Clausena lansium leaves and carbonized human hair, and the mass ratio is 1:(0.3 - 0.7).
[0019] In some embodiments of the present invention, the preparation method of the modified xanthan gum comprises the following steps:
[0020] (1) Add polyethylene glycol 15 - hydroxystearate to an ethanol aqueous solution, stir and then spray it on the surface of xanthan gum, dry, sieve, and obtain product 1 for standby;
[0021] (2) Mix product 1 obtained in step (1) with maltodextrin, and perform steam granulation to obtain product 2 for standby;
[0022] (3) Add product 2 obtained in step (2) to deionized water, stir, adjust the pH to 8 - 10, add polypropylene glycol diglycidyl ether while stirring, heat to 45 - 60 °C, stir, precipitate, wash, and dry to obtain the modified xanthan gum.
[0023] In some embodiments of the present invention, in step (1), the mass ratio of xanthan gum to polyethylene glycol 15 - hydroxystearate is 1:(0.5 - 0.9).
[0024] Preferably, in step (1), the mass ratio of xanthan gum to polyethylene glycol 15 - hydroxystearate is 1:0.6.
[0025] In some embodiments of the present invention, in step (2), the mass ratio of product 1 to maltodextrin is 1:(0.1 - 0.4).
[0026] Preferably, in step (2), the mass ratio of product 1 to maltodextrin is 1:0.2.
[0027] In some embodiments of the present invention, in step (3), the mass ratio of product 2 to polypropylene glycol diglycidyl ether is 1:(0.05 - 0.3).
[0028] Preferably, in step (3), the mass ratio of product 2 to polypropylene glycol diglycidyl ether is 1:0.1.
[0029] During the storage process of the disinfectant, it will experience the temperatures of all four seasons. Especially in winter in the north, the low temperature can reach minus ten or even twenty - odd degrees, which may cause the freeze - thaw phenomenon of the disinfectant during the high - low temperature change, seriously affecting the use effect of the disinfectant. The thickener xanthan gum has excellent emulsifying and suspending ability, which can effectively help improve the stability of the disinfectant. However, untreated xanthan gum has problems with poor dispersibility and its high - temperature resistance also needs to be improved.
[0030] On the one hand, the applicant sprays an ethanol aqueous solution of polyethylene glycol 15 - hydroxystearate on the surface of xanthan gum. Further, by controlling the ratio, product 1 and maltodextrin are combined through steam granulation to obtain product 2. The non - ionic surfactant polyethylene glycol 15 - hydroxystearate can adsorb on the surface of xanthan gum particles, shielding some hydrophilic groups of xanthan gum, changing the interfacial structure of its colloidal particles, and enabling better dispersion of xanthan gum particles. Maltodextrin forms an interaction force through hydroxyl groups and carboxyl groups on the surface of xanthan gum, thereby increasing the specific gravity of xanthan gum particles, effectively avoiding the problem of xanthan gum agglomeration, improving the dispersibility of xanthan gum, and maltodextrin has good water solubility and does not affect the performance of xanthan gum itself, enabling xanthan gum to have good water solubility, emulsifying and suspending ability while improving its dispersibility. On the other hand, the applicant introduces polypropylene glycol diglycidyl ether to cross - link and modify product 2. Certain cross - link points can be generated between polypropylene glycol diglycidyl ether and xanthan gum, thereby enhancing the thermal stability of xanthan gum.
[0031] In some embodiments of the present invention, the emollient is glycerol or hyaluronic acid.
[0032] In some embodiments of the present invention, the preparation method of the dodecenyl succinic acid glucose ester comprises the following steps:
[0033] Mix anhydrous glucose and deionized water and add them to a reaction vessel. Under the condition of 30 - 40 °C, while stirring, add an aqueous sodium hydroxide solution to adjust the pH = 8 - 8.5, stir for 20 - 40 min, add dodecenyl succinic anhydride, stir under the condition of pH = 8 - 8.5, adjust the pH = 5.5 - 6.5, stir, and freeze - dry to obtain dodecenyl succinic acid glucose ester.
[0034] In some embodiments of the present invention, the molar ratio of anhydrous glucose to dodecenyl succinic anhydride is 1:(0.1 - 0.45).
[0035] Preferably, the molar ratio of anhydrous glucose to dodecenyl succinic anhydride is 1:0.3.
[0036] The applicant uses anhydrous glucose and dodecenyl succinic anhydride as raw materials and controls the ratio between them to synthesize dodecenyl succinic acid glucose ester. The dodecenyl succinic acid glucose ester molecule contains a hydroxyl hydrophilic group and a long carbon - chain hydrophobic group and thus has the characteristics of a surfactant. Moreover, the synthesized sugar ester has the properties of being easy to rinse and mild to the skin, enabling the skin disinfectant prepared in this application to have the advantage of mild performance. Further, the applicant compounded dodecenyl succinic acid glucose ester and fatty alcohol polyoxyethylene ether sulfate to obtain a composite surfactant, which plays a role in synergistically reducing viscosity and foam, and improving mildness and ease of rinsing.
[0037] On the other hand, the present invention also provides a preparation method of a skin disinfectant containing a disinfection and hemostasis composition as described in the above technical solution, including the following steps:
[0038] S1. Mix the composite surfactant and the emollient, and stir at 40 - 60 °C for 5 - 10 min to obtain a mixture A for standby.
[0039] S2. Mix the modified xanthan gum, absolute ethanol, and deionized water, and stir to obtain a mixture B for standby.
[0040] S3. Add the mixture B to the mixture A, stir, add the disinfection and hemostasis composition, and stir to obtain the skin disinfectant containing the disinfection and hemostasis composition.
[0041] Compared with the prior art, the present invention has the following beneficial effects:
[0042] (1) The present invention synthesizes a skin disinfectant containing a disinfection and hemostasis composition with absolute ethanol, a disinfection and hemostasis composition, modified xanthan gum, a composite surfactant, etc. as raw materials. Through the synergistic effect among the components, the skin disinfectant has the characteristics of good mildness, stability, and disinfection and hemostasis functions.
[0043] (2) The present invention uses xanthan gum as a raw material, sprays an ethanol aqueous solution of polyethylene glycol 15 - hydroxystearate on its surface, and further controls the ratio to combine maltodextrin through steam granulation, and finally introduces polypropylene glycol diglycidyl ether for cross - linking modification to obtain modified xanthan gum, improving the dispersibility and thermal stability of xanthan gum.
[0044] (3) The present invention uses anhydrous glucose and dodecenyl succinic anhydride as raw materials, controls the ratio of the two to synthesize glucose dodecenyl succinate, and then compound the glucose dodecenyl succinate and fatty alcohol polyoxyethylene ether sulfate to obtain a composite surfactant, which has the characteristics of mildness to the skin and easy rinsing.
[0045] (4) The skin disinfectant prepared by the present invention has good mildness, stability, and disinfection and hemostasis functions, and can be widely applied to the field of disinfectants, having good commercial application value. Specific Embodiments
