Description

Technical Field

[0001] The invention relates to the field of preparations, and in particular to a disinfecting and moisturizing dual-effect temperature-controlled foam agent and a preparation method thereof. Background Art

[0002] Ethanol disinfectant is currently a widely used disinfectant in the fields of medicine and health. Ethanol is a good skin disinfectant and a fat solvent that can remove grease from the skin. It can also mechanically remove bacteria. It has good volatility and can dry the skin quickly.

[0003] Most of the ethanol disinfectants available on the market are made into gels and sprays, which are convenient to use. However, the disadvantage is that since ethanol can remove grease and evaporates quickly, it can easily cause dry skin and lead to problems such as cracked hands and skin.

[0004] Therefore, there is an urgent need for a disinfectant emollient that has both a disinfecting effect and can replenish oil and moisturize the skin. Emulsion is the best product for replenishing oil and moisturizing the skin. Emulsion can form a film on the surface of hands and skin, which is composed of water and oil and can moisturize hands and skin. However, ethanol is a fat solvent. In almost all emulsion products with ethanol added, ethanol is only used as a solvent in small amounts. Excessive use affects its stability, causing its emulsification system to be destroyed and unable to form a qualified product. At the same time, the formation process of the emulsion is mostly based on high-temperature emulsification, and ethanol will evaporate quickly under high temperature. If you want to prevent ethanol from volatilizing, you need to modify the equipment or cover the surface with liquid nitrogen. These methods will greatly increase the cost and development difficulty of the product.

[0005] Therefore, the art needs to provide a foam disinfectant containing ethanol as a disinfectant component, having a skin-moistening effect, and foam temperature control. Summary of the invention

[0051] The inventors have conducted extensive and in-depth research, and through a large number of screenings and tests, have provided a disinfecting and moisturizing dual-effect temperature-controlled foaming agent. The present invention adopts a specific oil phase composition, solves the problem that the emulsified system is difficult to form and easy to be destroyed due to the large amount of ethanol added to the emulsion, and thus provides an emulsion containing a high content (60-80wt%) of ethanol and a foaming agent prepared therefrom. On the other hand, the emulsion of the present invention can be formed by low-temperature emulsification, solves the problem of large-scale volatilization of ethanol, and greatly reduces the cost of the product and the difficulty of large-scale production.

[0052] At the same time, during the development process, it was surprisingly discovered that as the concentration of ethanol increased, the foam showed a temperature control effect, that is, the foam was sensitive to temperature, and at the right temperature, the foam would melt quickly on its own. Through debugging, the final product can be stable at room temperature below 30°C, and will melt into a colorless liquid on its own at body surface temperature. After disinfection, a protective film composed of water and oil will form on the surface of the hands and skin, which can moisturize the hands and skin and eliminate the dryness and cracking caused by the evaporation of ethanol.

[0053] The present invention has been completed on this basis.

[0124] Table 3

[0125]

[0126] The results of comparison of the use effects show that the foaming agent of the present invention not only contains ethanol content that can achieve a disinfection effect, but also can replenish the oil dissolved by ethanol, thereby moisturizing and protecting the skin and preventing problems such as dry skin and cracking caused by the foaming agent.

[0127] discuss

[0128] The concentration of ethanol in ethanol disinfectant must reach a relatively high concentration, preferably 70-80% (v / v). At the same time, ethanol is volatile and can be dangerous at high temperatures. Therefore, there are only two ways to add ethanol to the emulsion. One is to add ethanol after the emulsification is completed and the temperature is lowered; the other is to add ethanol before the emulsification reaction, but the emulsification reaction can only be carried out under low temperature conditions.

[0129] However, those skilled in the art know that when the amount of ethanol added to the emulsion exceeds 50% (v / v), the emulsification system is destroyed, the product is stratified and precipitated, and cannot be used. Therefore, ethanol needs to be added before the emulsification operation, i.e., low-temperature emulsification.

[0130] The addition of ethanol can reduce the system temperature in a large amount. Therefore, the oil phase components participating in the emulsification in the emulsification reaction must be able to maintain a stable state under a low temperature system. After a large number of screenings, the present invention finds that only the oil phase that is soluble in ethanol can maintain a stable state. Therefore, the primary condition for the selection of the oil phase component is that it can be soluble in ethanol. At the same time, since the components that can form a film at room temperature are mainly oil phase components, excellent film forming properties are also one of the conditions for the screening of the oil phase component. The present invention uses a specific two-component or three-component oil phase component, and further forms an emulsion suitable for preparing a foaming agent of the present invention by compounding with other components.

[0131] All documents mentioned in the present invention are cited as references in this application, just as each document is cited as reference individually. In addition, it should be understood that after reading the above teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
