Description

Shampoo shower gel for infants and children

The technical field is as follows:

the invention relates to the field of daily chemicals, and in particular relates to a shampoo and shower gel for infants.

Background art:

with the opening of the national three-child policy, the population number of infants tends to rise, and the infant and child products in the market come across opportunities and also bring challenges. The concern of the country to the cosmetics of children is more and more important, and the national drug administration formally publishes a special mark of the cosmetics of children, namely 'Xiaojindun', which is favorable for promoting the standardized development of the market of the cosmetics of children. But the infant products in the market still pay more attention to the market propaganda at present, and the design concept of the products is ignored. Generally, the skin after washing is sticky, the foam is not rich, the skin is jelly at low temperature, for example, the surfactant is only cleaned by amino acid surfactant, the insufficient cleaning force is easily caused by too little dosage, the pseudo-slip phenomenon is caused by too much dosage of washing, for example, the product is energized, active ingredients such as oat, chamomile and the like or Chinese herbal medicine ingredients are added to adjust the skin feeling or endow certain functions, but the product can contain risk substances such as methylisothiazolinone with cytotoxicity, DMDM hydantoin with possibility of releasing formaldehyde and the like. But the irritation of the product is easily increased, so that the skin barrier of the infants and children which is not developed to be mature is stressed.

Skin of young children has high water content, but has thin cuticle and high percutaneous water loss rate; the skin is delicate and the hair is not much and very soft; the sweat gland density is higher than that of adults, the function is weaker, the sweating temperature is slightly higher than that of adults, and the total amount of lipid secreted by sebaceous glands is less; the skin barrier is weak and sensitive to external stimuli. Therefore, the raw materials of the infant care product need to be strictly screened, the introduction of impurities is reduced, the types and the dosage of the used raw materials are reduced as much as possible on the basis of meeting the core performance (cleanness and foam), and essence, preservative, even colorant and other raw materials which are easy to cause adverse reaction to the delicate skin of the infant are used cautiously.

Therefore, the preferred choice of surfactants for existing shampoo or bath products is more of a nonionic or amphoteric surfactant to reduce skin irritation.

For example, CN202010268515.5 discloses a shampoo and bath lotion and its preparation method, wherein the shampoo and bath lotion comprises zwitterionic surfactant, sodium lauroyl sarcosinate, decyl glucoside, acrylate copolymer, PEG-80 sorbitan laurate, glyceryl oleate, dipotassium glycyrrhizinate, camellia seed oil, aloe extract, oat extract, PEG-40 hydrogenated castor oil, triethanolamine, benzyl alcohol and methyl chloro isothiazolinone, and a mixture of methyl isothiazolinone, magnesium chloride, and magnesium nitrate, perfume, disodium EDTA, and deionized water.

In the formula, ammonium lauryl alcohol ether sulfate is used as a main surfactant, cocoyl sodium glycinate is used as an auxiliary surfactant, cocoamidopropyl betaine, glycerol, jojoba oil and decyl glucoside are matched, a plurality of conditioners are used for preparing shampoo with excellent softening effect, and the anti-dandruff agent OCT is added and is matched with cocoamidopropyl betaine, so that the anti-dandruff shampoo has good anti-dandruff effect.

It discloses that the shampoo scurf-removing effect is improved by compounding a nonionic surfactant, an anionic surfactant, an amino acid surfactant and an amphoteric surfactant.

Patent CN 109718146 a discloses a children shampoo and bath lotion, which uses olive fruit extract, purslane extract, hydrolyzed wheat protein, mint and other components to provide the functions of sterilization and mosquito repelling, but methylisothiazolinone is also easy to cause irritation to the delicate skin of young children.

Patent CN 108904331A discloses a camellia oil shampoo and bath lotion for infants and a preparation method thereof, wherein, although camellia oil is used for caring skin, the camellia oil is strong in cleaning power and easy to cause over-cleaning due to the adoption of sodium laureth sulfate and cocamide DEA, and the camellia oil shampoo and bath lotion containing methyl thiazolinone and methyl isothiazolinone is easy to cause irritation to skin of infants in a bathing process.

TABLE 6 irritation evaluation Table

3 conclusion

TABLE 7 Mild test results

The results show that:

examples 1, 2 and 3 were compared with each other, and the same raw materials were used, but the amounts of the surfactants were different, and the results were different, and there was a risk that irritation was increased when the amount of the surfactant was increased in examples 1 and 3. Compared with the embodiment 1 and the embodiment 2, the surface active agent can be reasonably proportioned according to the dosage of the formula surfactant, so that the irritation of the system can be reduced.

Comparative examples 1, 2, 3, 4 and 5 are compared with each other, only one kind of surfactant is removed, the other kind of surfactant is unchanged, the result scores are different, the effect of selecting the kind of surfactant on the irritation of the system is shown, but the scores are higher than those of example 2, and the effect on the dosage ratio of the surfactant is larger than the irritation of the system is shown.

③ compared with the comparative example, 6, the example 2 shows that the irritation of the system is reduced by adding PPG-10 methyl glucose ether;

example 2 compared to example 11, it shows that the mildness achieved by example 2 is significantly better than that achieved by the commercial product.

Fifthly, comparing the example 2 with the examples 4,5 and 6, which shows that the mildness of the formula system can be influenced by various components, but the mildness is greatly influenced by the matching system of the surfactant;

sixthly, compared with the comparative examples 7,8,9 and 10, the surfactant of the same type is replaced by the surfactant of the same type one by one in an equal amount, but the irritation score is higher than that of the surfactant of the example 2, so that the surfactant of the example 2 is more suitable for matching.

TABLE 9 test results

The results show that

Comparing examples 1, 2 and 3 with each other, the effect of the dosage of the surfactant on the foaming amount of the system is large;

(xii) comparison of comparative examples 1, 2, 3, 4,5 with example 2 shows that the highest effect on foam is found to be amphoteric surfactant and the least effect is found to be amino acid surfactant;

EXAMPLE 2 compared to example 11, example 2 was slightly lower, but far more than the national standard of 40mm, enough to meet the needs of baby and children's bathing, and too high a foam height affected the speed of cleaning after bathing.

Comparing examples 1, 2, 3, 4,5 and 6 with each other, which shows that the reasonable collocation of the surfactant influences the foam quantity to the maximum extent;

comparison of examples 7,8,9,10 with example 2 shows that foam performance is still affected even with equivalent replacement of the same surfactant type in the formulation.

Fourth, trial test of population

1. Test protocol
