Precautions while using Shampoo
Shampoo for infants and young children is formulated so that it is less irritating and usually less prone to produce a stinging or burning sensation if it were to get into the eyes. For example, Johnsons Baby Shampoo advertises under the premise of No More Tears. This is accomplished by one or more of the following formulation strategies. 1 dilution, in case the product comes in contact with eyes after running off the top of the head with minimal further dilution. 2 adjusting pH to that of non stress tears, approximately 7, which may be a higher pH than that of shampoos which are pH adjusted for skin or hair effects, and lower than that of shampoo made of soap. 3 use of surfactants which, alone or in combination, are less irritating than those used in other shampoos.
