Description

Technical Field

[0001] The invention belongs to the field of daily chemical products, and in particular relates to a shampoo and bath cleaning product suitable for automatic bathing equipment and a preparation method thereof. Background Art

[0002] The aging population has given rise to the silver economy. With the advent of the intelligent era, automatic bathing equipment has become more and more common. Automatic bathing equipment has provided more and more care for the elderly with limited mobility. Automatic bathing equipment pumps shampoo and bathing products to the human body through a metering pump. If the general shampoo and bathing liquid is sprayed directly on the human body, the concentration is relatively high, and the irritation to the scalp and skin is also relatively large. Products with high viscosity are not easy to spread on the body surface, nor are they easy to foam. The skin of the elderly is more sensitive or fragile, so the impact is greater. Moreover, in order to ensure the stability of the discharge of the pumping system, the pumping amount cannot be too small. Therefore, the minimum pumping amount is very likely to exceed the amount of cleaning products required for shampooing and bathing. Using excessive cleaning products will cause dry hair and skin and make the body uncomfortable. Some automatic bathing equipment is equipped with a mixing pump, which uses the mixing pump to mix shampoo and bathing products and water in a certain proportion before pumping them to the human body; or the shampoo and bathing cleaning products are diluted in a certain proportion first, and the diluent is used directly when using them.

[0003] The most suitable concentration for general shampoo and bath products in contact with the skin is 10% (the national and industry standards for cosmetics such as GB / T 29679-2013 "Shampoo and Cream" and GB / T 34857-2017 "Bath Agent" require the pH of the product to be tested at a 10% aqueous solution. Therefore, a 10% solution is a more suitable concentration for actual use).

[0004] In order to increase the care effect on hair and reduce the irritation during bathing, shampoo and bath products generally add a small amount of cationic surfactants as conditioning agents. On the other hand, cationic surfactants can also react with anionic surfactants during the cleaning process to produce flocculation, which can moisturize the skin, bring a smooth feeling to the hair when flushing, reduce the resistance of wet combing of hair, and promote the deposition of silicone oil, anti-dandruff agents, etc. However, general shower gels do not produce flocculation when diluted, while shampoo produces flocculation when diluted 3-5 times. If it still has flocculation when diluted 10 times, the diluent with flocculation will produce precipitation after being placed for a period of time. If the product that has produced flocculation is pumped, it will not only affect the use effect, but also cause damage to the equipment; if the diluent has been deflocculated and restored to a clear state when diluted 10 times, the product will lose its conditioning effect on the skin and hair, and cannot achieve the purpose of reducing the irritation caused by anionic surfactants during cleaning, nor can it improve the dry and wet combing effects of hair. Moreover, general shampoo and bath products do not have antibacterial effects. According to relevant laws and regulations on cosmetics, the amount of preservatives added to cosmetics is limited. After the product is diluted, the concentration of preservatives in the system decreases, which is not enough to inhibit the growth of harmful microorganisms in the product. Therefore, if the automatic bathing equipment pumps the above products, it will not achieve the effect of the original formula design, and it may damage the machine, and even breed bacteria after dilution, endangering the health of users.

[0005] Therefore, it is necessary to develop a method for effectively controlling the generation of flocculation during the dilution process, so that the product remains clear and stable when diluted 10-10.4 times, is particularly suitable for direct use after dilution, and the diluted solution has an antibacterial effect, and can be a stable shampoo and bath cleaning product that can be stored for a long time. Summary of the invention

[0049] 5) When the temperature is below 40°C, add other raw materials such as water-soluble silicone, oil, moisturizer, plant extract, flavor, preservative, etc. as needed, stir evenly, and filter out the material.

[0050] 3. How to use the product

[0051] The product prepared by the formula of Example 1-28 is diluted 10-15 times and then put into the automatic bathing equipment for use. Ordinary consumers can also use the foaming bottle to foam directly after dilution, without rubbing, and can also avoid high-concentration personal cleansing products directly contacting the skin and causing irritation to the skin.

[0052] 2. Product performance test

[0053] Charge density is the number of milliequivalent charges per gram of polymer (meq / g). The charge density of cationic polymers is measured by colloid titration. Based on the principle that anionic polyelectrolytes and cationic polymers form a complex with a charge ratio of 1:1, a known concentration of anionic polyelectrolyte polyvinyl sulfate (PVSK) is used as a standard titration solution to titrate the cationic polymer aqueous solution. The charge density of the cationic polymer can be calculated based on the amount of polyvinyl sulfate consumed. The charge density here is only a relative value, which is used to characterize the amount of positive charge carried by the cationic polymer.

[0054] 1. Test on the relationship between product dilution ratio and transmittance

[0055] The transmittance (%T) of the sample is measured using an ultraviolet / visible light (UV / VI) spectrophotometer at a wavelength of 600 nm. Diluted samples of various weight ratios of water to the composition are prepared. As the dilution factor increases, flocculation occurs and the transmittance decreases. When the amount of flocculation is the largest, the transmittance reaches the lowest value. With continued dilution, the flocculation is diluted and the transmittance increases again. By adjusting the dilution factor of the sample and the change in transmittance, it is possible to simulate and determine how much flocculation the composition will form when the consumer applies the composition to wet hair, foams, and then rinses it off, and how long the slippery feeling of wet hair and skin flushed with water lasts.

[0056] When the transmittance (T%) is lower than 95%, a 100 mL tall beaker can be used to clearly observe that the transparency of the solution decreases and it begins to become turbid, which can be regarded as the appearance of flocculation; when the transmittance begins to increase again, it is the beginning of the deflocculation state, that is, the flocculation effect begins to weaken, and when the transmittance rises to 80%, it is regarded as the deflocculation is basically completed; the flocculation duration is the deflocculation basically completed multiple minus the flocculation appearance multiple, and the greater the difference, the longer the flocculation duration, and the longer the slippery feeling of wet hair and skin after flushing with water lasts.

[0057] The dilution multiples and transmittance data of the products of Examples 1-9 and commercially available products (reference products 1-9) having the same or similar functions are shown in Tables 4-7.

[0058] Table 4 Dilution multiples and transmittance data of Examples 1 to 6

[0059]

[0060] Table 5 Dilution multiples and transmittance data of Examples 7 to 9

[0061]

[0062] Table 6 Dilution multiples and transmittance data of commercially available products

[0063]

[0064] Table 7 Dilution multiple and transmittance data of commercially available products

[0065]

[0066]

[0067] The color of reference substance 1 is light blue. Due to the influence of pigment, the initial transmittance is low. After dilution, the color becomes lighter and the transmittance increases. After flocculation occurs, the transmittance decreases again. When the dilution factor is 2.09, it becomes slightly turbid and flocculation occurs, and deflocculation occurs after dilution 10 times.

[0068] Reference substance 2 is a basically colorless and transparent sample. The curve between dilution and transmittance is a normal variation curve. After being diluted to a certain multiple, the transmittance drops significantly and flocculation occurs. After continuing to drop to a certain multiple, the transmittance increases with further dilution. When the dilution multiple is 2.84, it becomes slightly turbid and flocculation occurs, and deflocculation occurs after being diluted 10 times.

[0069] The color of reference substance 3 is dark blue. Due to the influence of pigment, the initial transmittance is low. After dilution, the color becomes lighter and the transmittance increases. After flocculation occurs, the transmittance decreases again. After a certain multiple decrease, the transmittance increases with further dilution. When the dilution multiple is 3.2, it becomes slightly turbid and flocculation occurs, and deflocculation occurs after dilution 10 times.

[0070] Reference substance 4 is a basically colorless and transparent sample. The curve between dilution and transmittance is a normal variation curve. After being diluted to a certain multiple, the transmittance drops significantly and flocculation occurs. After continuing to drop to a certain multiple, the transmittance increases with further dilution. When the dilution multiple is 2.87, it becomes slightly turbid and flocculation is produced. Flocculation still exists when diluted 10 times.

[0071] Reference substance 5 is a basically colorless and transparent sample. The curve between dilution and transmittance is a normal variation curve. After being diluted to a certain multiple, the transmittance drops significantly and flocculation occurs. After continuing to drop to a certain multiple, the transmittance increases with further dilution. When the dilution multiple is 2.51, it becomes slightly turbid and flocculation occurs, and deflocculation occurs after being diluted 10 times.

[0072] Reference substance 6 is a substantially colorless and transparent sample. No flocculation occurs even when the sample is diluted to 100 times, and the transmittance is maintained above 95%.

[0073] The color of reference substance 7 is dark blue. Due to the influence of pigment, the initial transmittance is low. After dilution, the color becomes lighter and the transmittance increases. After flocculation occurs, the transmittance decreases again. After a certain multiple decrease, the transmittance increases with further dilution. When the dilution multiple is 1.69, it becomes slightly turbid and flocculation occurs, and deflocculation occurs after dilution 10 times.

[0074] The reference product 8 was slightly turbid. As the dilution ratio increased, the transparency of the product increased. Even when diluted to 100 times, no flocculation occurred and the transmittance was maintained above 95%.

[0075] Reference substance 9 is a basically colorless and transparent sample. The curve between dilution and transmittance is a normal variation curve. After being diluted to a certain multiple, the transmittance drops significantly and flocculation occurs. After continuing to drop to a certain multiple, the transmittance increases with further dilution. When the dilution multiple is 1.79, it becomes slightly turbid and flocculation is produced. Flocculation still exists when it is diluted 10 times.

[0076] like Figure 1-3 As shown, the products of Examples 1-9 of the present invention have not yet flocculated when diluted 10 times, but begin to flocculate when the dilution factor is greater than or equal to 10.5, and the flocculation lasts for a long time. The products can maintain the flocculation state after multiple dilutions, and can bring conditioning effects to the hair and skin during the entire shampooing and bathing time. Figure 4-5 As shown, the reference substances 1-5, 7 and 9 flocculate before the dilution times reach 10. When the dilution times reach 10, except for reference substances 4 and 9, the flocculates are basically completely deflocculated, and the dilution liquid returns to a transparent state. The reference substance 4 is diluted 15 times, and the reference substance 9 is diluted 13 times. The flocculation time is short. Although the complete deflocculation after dilution of 10 times is a stable state, it can no longer flocculate when used as a shampoo and bath product, and has no conditioning effect on hair and skin.

[0077] 2. Antibacterial effect test

[0078] According to WS / T 650-2019 "Antibacterial and Antibacterial Effect Evaluation Method" 5.1.1 Suspension Quantitative Antibacterial Test Method, the action concentration is 10% solution (mass concentration) and the action time is 20 minutes. After testing: the antibacterial effect of Examples 1-28 on Staphylococcus aureus is greater than 50%, proving that the product of the present invention has an antibacterial effect on Staphylococcus aureus; while the shampoo and bath cleaning products containing only one or a combination of two of the cationic surfactants, anionic surfactants and amphoteric surfactants have no obvious antibacterial effect on Staphylococcus aureus.

[0079] 3. Use effect survey

[0080] A consumer use effect survey was conducted on Example 1, Example 6, Reference 3 (multi-effect two-in-one shower gel) and Reference 9 (two-in-one sports water shampoo shower gel). 20 consumers were randomly selected at any time, 10 men and 10 women, aged 25 to 35 years old, healthy, and free of hair scalp diseases and skin diseases. The survey method was a blind sample test, and the samples provided included the original solution of the sample and the sample diluted 10 times. The consumers were surveyed on the richness of the sample foam, the fineness of the foam, the moisturizing feeling of the skin after use, the slippery feeling of wet hair after use, and the combability of dry hair after use.

[0081] 3.1 Investigation of sample foam richness

[0082] The foam richness of the sample is evaluated with a score of 0-5, and the higher the score, the richer the foam. Very rich foam 5 points; rich foam 4 points; medium foam 3 points; relatively little foam 2 points; very little foam 1 point; very little foam 0 point.

[0083] Table 8 Sample foam richness survey form

[0084]

[0085] 3.2 Foam fineness

[0086] The fineness of the sample's foam is evaluated using a score of 0-5, where the higher the score, the finer the foam: 5 points for very fine and soft foam; 4 points for fine and soft foam; 3 points for relatively fine foam; 2 points for relatively large foam; 1 point for large foam; 0 point for foam that is easily broken.

[0088]

[0089]

[0090] 3.3 Skin moisturizing feeling after use

[0091] The moisturizing feeling of the skin after use of the sample is evaluated using a score of 0-5, with the higher the score, the more moisturized: 5 points for skin moisturized but not tight after use; 4 points for skin relatively moisturized but not tight after use; 3 points for skin refreshed but not moisturized enough after use; 2 points for skin relatively dry after use; 1 point for dry skin after use; 0 point for skin dry and tight after use.

[0093]

[0094] 3.4 Slippery feeling of wet hair after use

[0095] The slippery feeling of wet hair after using the sample was evaluated on a scale of 0-5 points, with the higher the score, the better the slippery feeling of wet hair and the better the resistance to washing. When using, the wet hair feels very slippery, and the slippery feeling is maintained with continuous washing, 5 points; when using, the wet hair feels slippery, and the slippery feeling is maintained with continuous washing, 4 points; when using, the wet hair feels relatively slippery, and the slippery feeling is maintained for a short time with continuous washing, 3 points; when using, the wet hair feels relatively dry, 2 points; when using, the wet hair feels dry, 1 point; when using, the wet hair feels very dry, 0 points.

[0097]

[0098] 3.5 Combability of dry hair after use

[0099] The combability of dry hair after use of the sample was evaluated with a score of 0-5, with the higher the score, the easier the dry hair was to comb. After use, dry hair was very easy to comb 5 points; after use, dry hair was easy to handle 4 points; after use, dry hair was relatively easy to comb 3 points; after use, dry hair was difficult to comb 2 points; after use, dry hair was difficult to comb 1 point; after use, dry hair was tangled 0 points.

[0100] Table 12 Questionnaire on combability of dry hair after use

[0101]

[0102]

[0103] It can be seen from Tables 8-12 that: in terms of foam richness, the samples of Examples 1 and 6 of this patent have little difference in foam richness compared with reference products 3 and 9, whether used in stock solution or in 10% solution; but in terms of foam fineness, Examples 1 and 6 of this patent have finer and softer foam; compared with reference products 3 and 9, they have finer foam; in terms of skin feel after use, after using Examples 1 and 6 of this patent, consumers basically scored more than 4 points, and the skin was more moisturized and not tight after use, but the scores of reference products 3 and 9 were both 3 points, and the skin was refreshed after use, not enough Moisturizing; in terms of wet hair slippery feeling, after using the embodiments 1 and 6 of the present invention, the basic ratings of consumers are all above 4 points. When using, the wet hair feels slippery, and the slippery feeling is maintained well after continuous water washing. The ratings of the reference products 3 and 9 used directly are 3 points. When using, the wet hair feels slippery, and the slippery feeling is maintained for a short time after continuous water washing. When using the 10% reference product 3, the wet hair feels relatively dry and astringent, and the rating is only 1 to 2 points. When using the 10% reference product 9, the wet hair feels relatively dry and astringent, and the rating is only 1.5 to 2 points. This shows that the embodiments 1 and 6 of the present invention have good conditioning effects, whether used directly or diluted. When used directly, the conditioning effect is not affected. When the reference products 3 and 9 are used directly, the cationic surfactant still produces flocculation during the rinsing process, and there is a certain conditioning effect, but not as good as the embodiment 1 and embodiment 6 of the present invention. However, if diluted and used, the reference product 3 has been deflocculated and has no conditioning effect on the skin and hair, but the reference product 9 still has a small amount of flocculation, so the score is slightly higher than the reference product 3. In terms of combability of dry hair, the scores of the embodiments 1 and 6 of the present invention are basically above 4 points. After use, the dry hair is easy to comb, but the scores of the reference products 3 and 9 used directly are concentrated in 3 to 3.5 points. After use, the dry hair is relatively easy to comb. It is easy to comb, while the scores of the control samples using 10% are concentrated in the range of 2 to 2.5 points. The total score of control sample 9 is slightly higher than that of control sample 3. After use, dry hair is difficult to comb, which reflects that Examples 1 and 6 of the present invention have a good conditioning effect on the hair, and the cationic flocculation can be well adsorbed on the hair. When used directly, control samples 3 and 9 also have certain effects, but the effects are not as good as those of Examples 1 and 6 of the present invention. When diluted by 10%, control sample 3 has been deflocculated and has no conditioning effect on the hair, but control sample 9 still has a small amount of flocculation, so the score is slightly higher than that of control sample 3.

[0104] 4. Relationship between pH value and product stability

[0105] Table 13 pH values ​​and product stability test results of Examples 29-31 and Reference Substances 10-12

[0106]

[0107]

[0108] Studies have shown that: the pH adjuster of this patent not only adjusts the pH value of the product to between 4.8 and 5.8, but also makes the pH value of the product solution diluted to a mass concentration of 10% to be between 5.0 and 6.5. This diluted pH value is close to the pH of human skin, which reduces the irritation of the product to human skin and has unexpected effects in improving the transparency of the system and increasing the stability of the product. The reason why the pH adjuster can improve the transparency of the system and increase the stability of the product is estimated to be that when the system is in a weakly acidic environment, the amphoteric surfactant exhibits a certain cationicity and can play a "bridge" role between the cationic surfactant and the anionic surfactant. At the same time, because this patent selects a cationic surfactant with a lower charge density, under the joint action of the two, the ionicity of the cationic surfactant is weakened, allowing the anionic surfactant and the cationic surfactant to coexist in the system. Examples 29-31 all add citric acid to adjust the pH value, and the products are stable, and the dilution multiple for flocculation is 14.6-14.8, which is very suitable for use as a two-in-one shampoo and bath cleaning product; Reference product 10 does not add a pH adjuster, the product is unstable, and the appearance is turbid; Reference products 11-12, although a pH adjuster is added, the pH value is not adjusted within the range of 4.8-5.8, and precipitation is produced, and the stability is poor. However, with the increase of pH adjusters, the transparency of the product appearance increases, and the stability also increases. In summary, the pH range defined by the patented product can reduce the irritation of the product to human skin, and also has unexpected effects in improving the transparency of the system and increasing the stability of the product.
