Updated: Shabbos Alert Regarding Pampers Retracted By the Star-K


pampers[Update below.] Original report: Frum consumers should note that Pampers Swaddlers Sensitive and Pampers Feel ‘N Learn Advanced Trainer diapers change color when the diaper is wet or dirty. Poskim have therefore ruled that these diapers should not be used on Shabbos or Yom Tov.

This p’sak was released this month by the Star-K. You can read it by clicking here

UPDATED: We have been notified by the Star-K that they have retracted the previously publicized alert. In fact, the Pampers that change color indicating that the diaper is soiled or wet MAY be used on Shabbos. The Star-K has apologized for the misinformation.

  1. What is the difference in halacha between the color change brought about by the chemical reaction with the diaper and the color change brought about by the natural soiling?

  2. Coloring from food is no problem because of the rule of ain tzvia bochlim. (there is no dyeing by food).
    The coloring of toilet water with products such as Selson Blue are to be avoided on shabbos because you color the water.
    This is the pesak I have heard for years.
    In response to the questions posed by 1 and 2, you must say there is a distinction between coloring derech lichluch and for other purposes.
    The color of the diaper is an indicator and is therefore not derech lichluch.
    My question was, even so, the child is doing it derech misasaik, so why should it be an issue.
    Star K, I am guessing, wants you not to be maachil issur byodayim to the child.

  3. I wasn’t going to say anything then, but in retrospect, knowing that there was faulty logic regarding this Psak and having heard this from various other Poskim, instead of trying to be the first to post this info, perhaps Matzav should research before posting, like thinking before talking to maintain a positive image.

  4. Anyone know the “metzius” if the color of these diapers stays? if it doesnt then even if the change in color would be considered “nicha lei” it would be muttar just like photo-chromatic lenses?
