Description

Face cream with moisturizing and soothing effects and preparation method thereof

Technical Field

The invention belongs to the technical field of skin care products, relates to a facial cream with moisturizing and soothing effects and a preparation method thereof, and particularly relates to a facial cream with moisturizing and soothing effects, which has a very simple formula and is suitable for infants and a preparation method thereof.

Background

The skin of the infant and the child is obviously different from that of an adult in structure and composition, and the skin basic structure is that the skin layer thickness of the infant Tong Biao is thinner than that of the adult, so that the skin care product or the skin external product can permeate through the skin of the infant and the child more directly and easily than that of the adult, has stronger reaction to harmful substances and sensitization components, has complex formula components and contains the sensitization components such as essence, alcohol or pigment, and the skin care product containing the sensitization components such as essence, alcohol or pigment and the like is prevented from being used for the infant and the child as much as possible.

The barrier function of the skin of the infant is not fully developed, the barrier function is weaker than that of an adult and is easier to damage, and the corresponding percutaneous water loss speed is faster than that of the adult, so that the skin barrier is stabilized by increasing the moisture retention and the moistening of the skin of the infant is particularly important. Melanin is produced by melanocytes in the skin and is capable of absorbing radiant energy from sunlight, thereby protecting the skin from ultraviolet light. It has been found that the skin of infants is significantly lower in melanin than that of adults, while the melanocyte function of children is still imperfect, and these characteristics make the skin of infants more vulnerable to ultraviolet rays, thus easily causing a series of skin inflammatory reactions such as itching and redness.

The prior art discloses several functional cream products for infants and children, for example CN108904330a discloses a baby skin care camellia oil cream consisting of water, camellia seed oil, diglycerol, butylene glycol, glycerol, triglycerides, shea butter, polydimethylsiloxane, cetostearyl alcohol, stearyl glyceryl, citrate esters, phytosterol oleate, 1, 2-glycol, white pool flower seed oil, begonia seed oil, sodium hyaluronate, gentian extract, panthenol, tocopheryl acetate, acrylic/C10-30 alkanol acrylate cross-linked polymers, allantoin, sodium stearoyl glutamate, capryl glycol, xanthan gum, arginine. Can effectively relieve the daily skin problems of infants, can rapidly improve the problems of dry, reddish and rough skin of infants, and the like, care the tender skin of infants, and have mild ingredients and no hormone.

The formula design of the cosmetic for infants should follow the safety priority principle, the efficacy essential principle and the formula extreme simple principle. It can be seen that the requirements of infant Tong Hufu are obviously different from those of adult skin care products, and the requirements are concentrated on the aspects of high safety, necessary efficacy and extremely simple formula. In recent years, consumers pay more and more attention to the safety and efficacy of cosmetics, and especially the formula requirement of infant cosmetics is limited to safety and efficacy, and consumers pay more and more attention to the extreme simplicity of formula design, but the number of infant Tong Huazhuang products meeting the requirements on the market is very small. Therefore, it is necessary to develop a cosmetic which is excellent in moisturizing and soothing effects, has extremely simple formulation components and is safe and suitable for infants.
