    MIT as supplied with CMIT at total ~5ppm in rinse off products is safe in use and continues to be primary in that context.

    You’ll have to better define what you mean by “safer”. 
    How would you measure one thing is safer than another?

    That depends…what’s the product type, pH, and how much water do you have in it?
    Phenoxyethanol is probably your best best though.

    Think phenoxy is not needed with DMDM Hydantoin and Parabens - the classic combination is a formaldehyde releaser and parabens but add EDTA.,

    قال PhilGeis :

    يعتبر MIT كما هو مزود بـ CMIT بإجمالي حوالي 5 جزء في المليون في منتجات الشطف آمنًا في الاستخدام ولا يزال أساسيًا في هذا السياق.

    مناديل مبللة هي منتجات شطف؟

    Wet wipes have no rinsing step like shampoos - so are leave on.
