Description

Technical Field

[0001] The present invention relates to a honeysuckle softening shampoo and a preparation method thereof, belonging to the field of daily-use cosmetics. Background Art

[0002] In shampoos, the main surfactant used is the anionic surfactant alkyl ether sulfate type. The surfactants commonly used in shampoos on the market currently are sodium lauryl polyether sulfate (SLES) and ammonium lauryl sulfate (ALS). The main function of the thickening system is to increase the viscosity of the shampoo, and the thickeners include sodium chloride, cocamidopropyl betaine, acrylic acid, hydroxyethyl cellulose, and gums. Cationic conditioners are important raw materials for preparing shampoos. Pearlescent agents can adjust the color of the shampoo and enhance its aesthetic feeling. The basic requirements for shampoos are as follows: having good foaming properties, rich and dense foam during washing, being able to effectively remove greasy dirt and dandruff on the hair; being easy to spread, easy to wash, and having a suitable viscosity; moisturizing the hair and being easy to comb. The selection of shampoo accessories directly affects the problems of scavenging free radicals, delaying skin aging, and promoting skin metabolism functions, resulting in poor final use effects and experience for users. Summary of the Invention

[0003] The technical problem to be solved by the present invention is how to enable the shampoo to have the functions of scavenging free radicals, delaying skin aging, and promoting skin metabolism.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions

[0005] A honeysuckle softening shampoo, by weight percentage, has the following formula:

[0006] Honeysuckle extract 0.8%, sodium lauryl polyether sulfate (SLES) 12.0%, ammonium lauryl sulfate (ALS) 4.0%, sodium chloride 2.0%, guar gum hydroxypropyltrimethyl ammonium chloride 1.0%, ethylene glycol distearate 2.0%, polydimethylsiloxane 1.0%, glycerol

[0007] 1.5%, daily-use essence 0.3%, cocamidopropyl betaine 0.6%, citric acid

[0008] 0.2%, and the balance is water.

[0009] A preparation method of a honeysuckle softening shampoo includes the following steps:

[0010] Step 1: Select a honeysuckle extract solution obtained by extracting honeysuckle using a honeysuckle extraction process with an ethanol concentration of 81%, a solid-liquid ratio of 1:15 g / mL, and an extraction time of 74 min;

[0011] Step 2: Prepare Material A in the shampoo raw materials. Material A is composed of 12% sodium lauryl polyether sulfate (SLES), 4% ammonium lauryl sulfate (ALS), 2% sodium chloride, and 2% ethylene glycol distearate.

Specific Embodiments

[0016] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] I. Screening of Auxiliary Materials

[0018] 1 Materials

[0019] In order to fully exert the antioxidant and anti-aging effects of Lonicera confusa, the present invention is a cosmetic shampoo with the functions of scavenging free radicals, delaying skin aging, and promoting skin metabolism. The main components of this shampoo include surfactants, thickening systems, conditioning components, anti-dandruff and anti-itching components, preservation systems, pH regulators, and other necessary components.

[0020] Through screening in terms of foam performance, cleaning ability, thickening performance, and flocculation performance, the following auxiliary materials are finally selected for this product.

[0021] 1) Main surfactants: Sodium lauryl polyether sulfate (SLES) and ammonium lauryl sulfate (ALS) have strong detergency, produce relatively low irritation, have a mild use feeling, high foaming ability, are easy to produce dense and rich foam, good anti-hard water property, strong compatibility, and excellent thickening property.

[0022] 2) Sodium chloride and cocamidopropyl betaine: They are electrolyte thickeners with low prices. They can weaken the electrostatic repulsion of groups, and the decomposed ions can form micelles with surfactants, improving the viscosity of the shampoo.

[0023] 3) Guar gum: It can make dry and rough hair smooth and easy to comb. In the present invention, a compounding method of dimethicone and cationic conditioner guar gum is adopted.

[0024] 4) Skin conditioner: In the present invention, dimethicone and glycerol are selected, which are good for moisturizing the skin.

[0025] 5) Ethylene glycol stearate: It directly reflects its stable pearlescent effect, as well as functions such as thickening and conditioning.

[0026] 2 Research methods

[0027] In addition to the selection of auxiliary materials, the proportion of auxiliary materials in the shampoo also has an important impact on the various properties of the finished product. In the present invention, by changing the mass ratio of each auxiliary material in the formula, different shampoo formulas are prepared, and the physical and chemical properties of the prepared shampoo products are evaluated from four aspects: foaming performance, viscosity, hair bundle softness, and stability, to determine the optimal proportion of the formula. The specific experimental methods are as follows.

[0028] 1) Foaming performance: Weigh SLES, ALS, and cationic conditioner guar gum according to the formula design in a 100 mL beaker, then add deionized water at a temperature of 70 °C - 80 °C, and stir until completely dissolved. When the temperature drops to 40 °C, add citric acid to adjust the pH to about 6. The foam performance test process (refer to GB / 29679-2013): Add the above sample to a 1000 mL beaker, add 100 mL of hard water (0.4995 g of calcium chloride and 0.3615 g of calcium sulfate dissolved in a 500 mL volumetric flask), and finally add an appropriate amount of deionized water to make up the water to fully dissolve the sample.

[0029] 2) Viscosity: Weigh the formula amount of SLES, ALS, guar gum, SF-1, or a little sodium chloride and cocamidopropyl betaine in a 100 mL beaker, add an appropriate amount of deionized water at 70 °C - 80 °C, stir until completely dissolved, then cool to room temperature, supplement the remaining water, and finally weigh an appropriate amount of water and citric acid to adjust the pH of the shampoo system to about 6.0. Use a rotational viscometer to measure the viscosity of the sample under a certain rotational speed.

[0030] 3) Hair bundle softness test: Weigh the formulated amounts of SLES, ALS, and sodium chloride in a 100 mL beaker, add an appropriate amount of deionized water at 70 - 80 °C, stir until completely dissolved, then cool to room temperature. Add the formulated amounts of polydimethylsiloxane and the cationic conditioner guar gum, supplement the remaining water, and finally weigh an appropriate amount of citric acid to adjust the pH of the shampoo system to about 6.0.

[0031] 4) Stability performance test: Prepare 3 beakers, labeled 1, 2, and 3 respectively. Weigh 3 portions of 10 g of shampoo and place them in the 3 beakers, then seal them with plastic wrap. Among them, Shampoo No. 1 is placed in a -5 °C refrigerator, Shampoo No. 2 is placed at 25 °C room temperature, and Shampoo No. 3 is placed in a 40 °C incubator. Observe the stability changes of the shampoo after standing for 24 h, 48 h, and 96 h respectively and evaluate them.

[0032] 3 Single - factor screening

[0033] Based on the preliminary pre - experiments, the present invention has determined the approximate proportion range, and the proportions are varied within the range. The main surfactants (SLES, ALS) are shown in Table 1, the thickening system (SF - 1, sodium chloride) is shown in Tables 2 and 3, and the conditioning system is shown in Table 4 for screening. The corresponding proportion results are as follows. When the surfactants are 12% SLES and 2% ALS, the effect is more advantageous. For the thickener, 2% sodium chloride has a good effect. In the conditioning system, 1% cationic conditioner guar gum, 1% polydimethylsiloxane, and 1.5% glycerol have a better effect on the skin.

[0044] 3 Analysis results of screening formula for mixing excipients

[0045] According to the above single factor screening, the effects of Formulas 3, 13, and 19 are better, as shown in Table 5. Five portions of shampoo were prepared, and the obtained shampoo was evaluated in terms of foaming performance, viscosity, hair strand softness, and stability. The results are shown in Table 6. As can be seen from the table, when Formula 2 is used, the foaming performance is good, the number of bubbles is moderate and fine and smooth; the viscosity is moderate, neither overly viscous and stringy nor difficult to mold; the quality is stable, without obvious changes, and it is not easy to deteriorate during good storage; the cleanliness is excellent, which is the best among all formulas.

[0050]

[0051] Screening of the dosage of Lonicera hypoglauca Miq. extract

[0052] On the basis of Shampoo Adjuvant Formula 2 of the present invention, extracts were added, and their ratios were continuously experimentally adjusted. The appearance, color, cleanliness, ductility, etc. of the prepared shampoo were detected. The shampoo formula was screened to preliminarily determine the formula substances and dosages of the shampoo. Through preliminary pre-experiments, a general ratio range was determined, and the ratio was changed within the range. Five relatively reliable formulas were screened, and the screened formula ratios are shown in Table 7. Five portions of shampoo were prepared according to the 5 formulas, and the obtained shampoo was evaluated in terms of cleanliness, ductility, centrifugation, viscosity, and foamability [1, 2]. The results are shown in Table 8.

[0053] As can be seen from Table 8, the dosage of the extract has little effect on foamability. The viscosity of Formula 4 is moderate, the ductility is strong, it will not be severely stringy and will not break easily, and the use feeling is just right. The cleaning power is strong, and there are a small number of bubbles during centrifugation, indicating less impurities, high solubility of the components, and easy absorption by the human skin. This is the best choice among all formulas, so the present invention adopts the ratio of Formula 4 to prepare the shampoo.
