Abstract
The invention discloses transparent shower gel which comprises the following raw materials in percentage by weight: 10-80% of liquid soap base, 0-2% of acrylate copolymer, 0-1% of potassium hydroxide, 0-0.8% of buffering agent, 0-0.2% of chelating agent and the balance of water, wherein the pH value of the transparent shower gel is 9.5-10; according to the invention, the transparent shower gel is obtained by compounding the liquid soap base added with the acrylate copolymer and the specific raw materials in proportion, and the corresponding cold preparation process is adopted, so that the preparation method of the transparent shower gel is simple and strong in practicability, and the prepared shower gel product has the advantages of transparent appearance, abundant foam, strong cleaning power, easiness in washing, mild moisture, no stimulation and the like.
Description
Technical Field
The invention belongs to the technical field of shower gel, and particularly relates to transparent shower gel adopting a cold compounding process and a preparation method thereof.
Background
The description of the background of the invention pertaining to the related art to which this invention pertains is given for the purpose of illustration only and for the purpose of facilitating an understanding of the contents of the present invention, and should not be taken as an admission or admission that the applicant expressly considered or assumed that the applicant considered prior art to the filing date of the first filing date of the present application.
The bath lotion is a liquid cleaning agent used in bathing. The national standards of body wash classify body washes into two categories, soap-based and non-soap based, based on the type of primary surfactant used in their formulation. The soap-based shower gel is modified based on a soap making principle, has the advantages of rich foam, strong cleaning power, easiness in cleaning and the like, but also has the defects of skin irritation, insufficient moisture and the like caused by high degreasing power and water loss rate. The soap-based shower gel has development difficulty in stability. Firstly, the paste is easy to form at low temperature and is not easy to be matched with an outer packaging material for use; the cleaning agent is easily divided into a plurality of layers at low temperature, so that the cleaning effect is reduced; and the soap base shower gel is difficult to thicken and difficult to meet the user experience.
The soap base is used as one of the main raw materials of the soap base bath lotion and can be divided into two types according to the forms, namely a liquid soap base and a solid soap base, the existing liquid soap base generally contains fatty acid potassium, in a system with freely moving chemical molecules, fatty acid radicals in the fatty acid potassium are easy to contact with hydrogen ions in the system to form fatty acid, the fatty acid formed by the fatty acid radicals is easy to combine with the hydrogen ions along with the reduction of the solubility of the fatty acid under the low temperature state, and the fatty acid is separated out of the system, so that the layering phenomenon is generated, the existing liquid soap base has the defects of poor stability, easy separation of paste under the low temperature state, difficult stable storage and the like, so the soap base is difficult to be widely popularized and used in the market, the solid soap base exists in the solid form, the stability of the soap base is ensured, but the main component of the solid soap base is a sodium octadecanoate, the alkalinity is, when the soap is applied, solid soap base needs to be stirred strongly, converted into heat energy through mechanical energy, heated and softened and then extruded and molded to form soap blocks, so that when the solid soap base is used for preparing products, energy for softening the solid soap base needs to be increased, and the injection molding and demolding time needs to be prolonged, so that the production cost of the products is increased. The liquid soap-based shower gel is convenient to use, good in cleaning power, rich in foam, easy to wash, moist and comfortable after use, and has excellent use experience of consumers, so that the liquid soap-based shower gel is deeply loved by the consumers.
Modern consumers prefer individual care cleansing products with transparent packaging and transparent texture. Consumers can see the content substances more intuitively, and the purchasing desire is enhanced. However, the soap-based bath lotion with a transparent appearance has poor stability at low temperature, is easy to precipitate, fog and the like, and is particularly obvious for transparent soap-based bath lotions containing high content of fatty acid. In order to achieve the transparent effect of the bath lotion, in terms of fatty acid composition, the dosage of long-carbon-chain fatty acid is required to be controlled as much as possible, the neutralization degree of the soap base is required to be improved (even more than 100%, and the pH is at least more than 10), so that the content of the soap anionic surfactant is increased and the content of free fatty acid is reduced, which can also cause irritation of the product. Can not meet the pH value in the national standard GB/T34857-2017 bathing agent: 4.0-10.0.

In a transparent shower gel system, the solubility of free fatty acid is extremely low at low temperature, and the free fatty acid is easy to separate out from the system to cause the product to be layered. The acrylate copolymer has strong suspension capacity, can prevent chemical molecules from freely moving, effectively prevents free fatty acid from precipitating out of a system, and avoids product layering, so that the shower gel is presented in a transparent form.
The liquid soap base is introduced into the transparent shower gel, the saponification is carried out by adopting fatty acid and potassium hydroxide, and the acrylic ester copolymer is added as a suspending agent to keep the liquid soap base stable, so that the problems that the soap base is difficult to apply to a transparent system and the thickening is difficult are solved, meanwhile, the low temperature resistance of the transparent shower gel is greatly improved by the suspending capacity of the acrylic ester copolymer, in the raw material formula of the transparent shower gel, as the liquid soap base contains the acrylic ester copolymer, the weight percentage of the acrylic ester copolymer in the formula is correspondingly reduced along with the increase of the weight percentage of the liquid soap base in the formula, when the weight percentage of the liquid soap base in the formula reaches a certain value, the weight percentage of the acrylic ester copolymer in the system meets the formula requirement, the acrylic ester copolymer does not need to be added, but when the suspending capacity needs to be enhanced in the system, the amount of the acrylate copolymer can be increased in a proper amount, and if suspended particles are added into the system and need to be suspended in the system, more acrylate copolymer needs to be added to improve the suspending capacity of the system.
The potassium hydroxide is used for neutralizing the acrylate copolymer and free fatty acid, so that the acrylate copolymer expands after absorbing water, and the suspending and thickening capabilities of the acrylate copolymer are realized. And the fatty acid is neutralized to form fatty acid potassium, so that free fatty acid in the system is reduced, and the phenomenon that the product is layered due to the fact that the system is separated out along with the reduction of the solubility of the fatty acid when the temperature is reduced is avoided.
When the pH value of the transparent shower gel is adjusted, the adjustment of the pH value is stabilized through the action of a buffering agent in a system, so that the adjustment of the pH value is stably carried out, the phenomenon of sudden drop or sudden rise in the adjustment of the pH value of the shower gel is avoided, the adjustment operation of the pH value is simpler, and the adjustment precision is improved.
The metal ion exists the transparency that can influence the shower bath and makes the shower bath mix metal ion's color in the shower bath to metal ion concentration is too high can strengthen the irritability of shower bath, through adding the chelant in the system, the chelant chelates with the metal ion in the system, thereby reduces the concentration of metal ion in the system, makes the stability of shower bath improve, and the shower bath is gentler, and moist effect improves.
Meanwhile, in order to improve the consistency of the shower gel, a thickening agent can be added into the system, and the consistency of the shower gel can be blended according to different consistency requirements. In addition, in order to enable the shower gel to carry various fresh fragrances, a proper amount of essence can be added into the system, and the types of the essence can be added according to the preference of various people, including fruit essence, flower essence, milk essence and the like. When the viscosity and the transparency in the system are not well adjusted, the surfactant can be added into the system, the stability of the system is further improved through the micelle action of the surfactant, the transparent shower gel can be thickened through the micelle action among the surfactants, and the problem that the transparent system is difficult to thicken is solved.
