Sarahu says…I think this is an old urban legend that has been going around for years. People keep saying that Johnson & Johnson ‘No more tears’ baby shampoo contains secret numbing agents so that a baby’s eyes won’t sting if the shampoo gets in them. I think that any numbing agent would be required to be listed in the ingredients label. They keep insisting that numbing agents are in there, despite all evidence to the contrary. Can you settle this once and for all? Is there anything in J&J baby shampoos that would numb a baby’s eyes?
The Beauty Brains respond:
There are no numbing agents in the J&J’s baby shampoos.
One of the key attributes in producing a no-more-tears formula is the micelle size (micelles are aggregations of surfactant molecules), the bigger they are the less irritating they are The theory is the bigger micelles can not penetrate the eye membrane and hence cause irritation. The pH of the product, salt content, and impurities in the raw materials are also critical.
When I first heard this urban legend the “numbing” properties were attributed to the ingredient benzyl alcohol. I believe it was part of the preservative system in J&J baby shampoo at one point in time but it’s no longer used in this product. It is, however, still contained in a few of J&J’s baby lotions.
So, the bottom line is: myth busted! (Thanks to Alchemist for the micelle discussion!)
