Development of the shampoo for children

Abstract

Children, especially infants, have a sensitive and very vulnerable skin. Cosmetics for children supports the protective functions of the skin, making it less susceptible to a variety of stimuli. That is why children from the first days of life need other, safer skin care cosmetics than adults, it should not have the irritating action. In order to develop a foam cleaning product (shampoo) for children we have chosen a number of modern detergents of anionic, non-anionic and amphoteric character, such as 28% disodium laureth sulfosuccinate (“Euronaat LS 3”, Disodium Laureth-3-Sulfosuccinate, “EOS”, Belgium); cocamidopropyl betaine (“Сocamidopropyl Betain”, “KAO”, Japan); coco glucoside and glyceryl oleate (“Lamesoft PO 65”, Coco Glucoside (and) Glyceryl Oleate, “BASF (ex-Cognis)”, Germany); PEG-7 glyceryl cocoate (“Neopal LIS 80”, PEG-7 Glyceryl Cocoate, “Industria Chimica Panzeri”, Italy). Lactic acid was used as a pH adjustor. Based on these substances the foam cleaning bases in various concentrations of detergents have been prepared. The quality (physicochemical properties) of the foam cleaning bases developed has been assessed according to the current normative documents of Ukraine. At the first stage of the research it was determined that the use of “Euronaat LS 3” was irrational because it did not provide the required foam formation, hence, it was necessary to add other detergents. At the next stage the bases with addition of detergents with the low irritating effect, such as “Cocamidopropyl Betaine”, “Lamesoft PO 65”, “Neopal LIS 80”, were studied to improve the physicochemical and consumer properties. It has been found that foam cleaning bases with additionally selected non-ionic and amphoteric detergents improved the properties of the foam cleaning base developed, namely the level and stability of the foam and its consumer properties increased. It should be noted that the bases developed were stable at the pH value selected (5.5-6.5). The baby skin like all other organs develops gradually. And though at first glance it differs little from the adult’s skin, it may take a lot of time before the baby’s skin can fully perform all of its functions. Functions of the skin are diverse, but the main function is protective. This function in children is poorly expressed as evidenced by the easily vulnerable skin, frequent infections due to insufficient keratinization of the stratum corneum and its thinness, immaturity of the local immunity and intense blood supply. These peculiarities make the baby skin tender and prone to inflammation, in par ticular with poor care; that is why the skin care in children assumes daily hygiene and water procedures. Children, as well as adults, also need hair care. It is known that the skin of the baby’s head does not yet contain special natural protective film, which adults have. That is why microbes and other harmful substances penetrate through the children skin faster than in adults. It is obvious that the products for the baby skin care must meet other criteria than the products for adults. Since the skin of a normal healthy child is capable to cope with its fun
