Description

 The invention relates to medicine, namely to the production of cosmetics intended for skin care of children.

 The Open Joint-Stock Company Cosmetic Association Liberty produces a series of creams for children: Children's, Alice. However, all these creams are related to water / oil emulsions, ie, fat creams. The task of the developers of the new cream for children was creation of a liquid milk cream (type of emulsion oil / water), which has a targeted moisturizing effect and protects the skin of children from drying out.Thanks to the content of chamomile and calendula extracts, milk removes redness, softens and soothes the skin.

 Known means for skin care for children containing oils with plant extracts: baby oil "Viktorosh" [1] perfume and cosmetic factory "Viorika" and baby oil balm "Pantry of the Sun" [2], developed by LLP "Biocosmetic Factory", Novosibirsk

 Closest to the claimed is a baby cream "Sissy" produced by AOOT Ufa cosmetics factory "Enchantress" [3].

 The main advantages of the claimed cosmetic liquid cream for children are its high moisturizing ability, hypoallergenicity and bactericidal effect.

 The cream, which is a milk, is very convenient to use: it is lightly applied to the baby’s skin and distributed evenly, without additional effort. The cream promotes the formation of a uniform film on the skin surface, which protects the skin of infants from drying out, makes it smooth, soft and elastic.

 The cream has an epithelizing effect on rough skin, thereby eliminating peeling. The pronounced bactericidal properties of calendula against a number of microbes (especially staphylococci and streptococci) have an anti-inflammatory effect. Chamomile extract enhances regenerative processes, weakens allergic reactions and has a local anesthetic effect, relaxing smooth muscles, eliminating spasms.

 The difference between cosmetic cream for children from the prototype, see table. 1.

Characteristics of the main raw materials
The main goal of baby skin care is to protect the skin from overdrying, therefore it is necessary to introduce as much water as possible into the oil / water system. Oils, fats and waxes - the second main component of cosmetic emulsions after water. Their main task is to form a uniform film on the skin surface, which protects the skin from drying out, makes it smooth, soft and elastic. Therefore, it is very important to ensure the stability of the emulsion with a low content of structure-forming substances - hostacerin DGL, hostacerin DGS. Carbomers that gel and thereby stabilize the milk serve this purpose.

 Substances with the ability to soften the skin are called emollients (from the English word emollient - emollient). Emollients - a broad concept that unites substances of different chemical groups, which have one common property - soften the skin. Emollients are divided into hydrophilic and lipophilic. Glycerin is a hydrophilic emollient, and cetiol SN is a liquid lipophilic emollient.

 Cetiol SN (Henkel, Germany) or Tegosoft SI (Goldschmidt AG, Germany) - cetearyl isonanoate.

 An additional mobility of the system is given by a slight addition of citric acid in combination with the emulsifying agent - cetiol SN.

 Structuring emulsifiers are selected from the group consisting of hostacerin DGL and hostacerin DGS.

Хостацерин DGS - ПЭГ-4 полиглицерил-2 стеарат (продукт фирмы Hoechst)

где R - стеариновая кислота
Масляную фазу выбирают из группы, состоящей из изопропилпальмитата или изопропилмиристата и из минеральных масел - парфюмерного или вазелинового.Hostagerin DGL - PEG-10 polyglyceryl-2 laurate (product of the company Hoechst)

where R is lauric acid
Hostagerin DGS - PEG-4 polyglyceryl-2 stearate (product of the company Hoechst)

where R is stearic acid
The oil phase is selected from the group consisting of isopropyl palmitate or isopropyl myristate and from mineral oils - perfume or petroleum jelly.

Isopropyl Myristate - C ₁₃ H ₂₇ COOH (CH ₃ ) ₂
The ester of myristic acid and isopropyl alcohol. This low-viscosity product combines well with all types of cosmetic raw materials, it is easily emulsified, it allows to obtain low-viscosity emulsions that are easily absorbed into the skin, without leaving a sticky and oily feeling, soften the skin well. When it is introduced into liquid creams (up to 10%), their viscosity at low temperatures does not increase as sharply as when using vegetable oils [4].

Isopropyl palmitate - C ₁₅ H ₃₁ COOH (CH ₃ ) ₂
Palmitic acid ester and isopropyl alcohol. It is used similarly to isopropyl myristate [5].

 Gelling agents are selected from the group consisting of carbopol or carbomer, or sacapa, or sacapa-P.

 Carbopol, carbomers, sakap, sakap-P are rare crosslinked copolymers of acrylic acid and polyallyl esters of pentaerythritol, used to thicken polar systems and as a binder with a wide spectrum of action.

 Dietary supplements are selected from the group consisting of: allantoin and oil extracts from chamomile flowers and from marigold flowers.

 Allantoin (5-ureidohydantoin) is classified as a safe and effective skin protective product. It has an epithelizing effect on rough and cracked skin, eliminates peeling and callosity, makes the skin smooth and supple. In the presence of allantoin, the regenerative properties of the skin are enhanced. When added to face and body skin care products, it provides softness, silkiness of the skin, it acquires a clean, well-groomed appearance.

 Oil extract from marigold flowers has a calming effect on the central nervous system, lowers reflex excitability. The pronounced bactericidal properties of calendula were found for a number of microbes (especially staphylococci and streptococci). Calendula preparations are used in practical medicine mainly externally for the treatment of purulent wounds, burns, long-term non-healing ulcers, fistulas, epidermophytosis, eczema, furunculosis.

 The chamomile oil extract contains essential oil, which includes chamazulen, terpene, sesquiterpen, sesquiterpene alcohols, cadinene, caprylic, nonyl, antimis and isovaleric acid. The action of chamomile preparations is due to a complex of substances - especially chamazulen and matricin, chamazulen has a pronounced anti-inflammatory effect, it enhances regenerative processes, weakens allergic reactions and has a local anesthetic effect. Chamomile essential oil has a disinfecting effect, reduces gassing in the intestines, reduces pain, and reduces inflammation. It was established in experiments that chamomile glycosides block the parasympathetic nervous system, relax smooth muscles, eliminating spasms.

 The combination of marigold and chamomile extracts is classic and hypoallergenic for the delicate skin of newborns.

 The preservative is Germaben II, which is a viscous liquid.

 The combination of urea diazolidinyl dissolved with propylene glycol with methyl paraben and propyl paraben is effective against gram-positive and gram-negative bacteria, as well as against fermentation and mold. This gentle preservative is especially effective in protecting baby cosmetics.
