any active ingredient in a hand sanitiser will be toxic to microbes, simply because the entire purpose of a hand sanitiser is to kill microbes

if it doesn’t kill microbes, it’s not a hand sanitiser

The only issue with alcohol would be that it dries the skin, other than that it should be ok…

The world seems to be full of different brands of hand sanitiser.

Are you certain you want to enter this very overcrowded market?

@em88 - there is little scientific evidence that alcohol dries the skin.

And there are certain humectants which can be added to counter the drying and plasticizing the resin in the formulation. In premium segments, Ucon Fluid 75-H-450 is one of my favorites.

Resin in hand sanitizers?

These products are made as cheap as possible to be able to get a position on a VERY oversubscribed product platform.

OK, it may be feasible (just) to aim at a “luxury” consumer market but this is tiny compared with the marketplace available in healthcare - where there seems to be a queue of salesmen at their doors touting their “better” hand sanitizer.

There is a similar situation with gel lubricants - large numbers of sales personnel (possibly the same ones trying to sell hand sanitizers) offering gel lubricants for various scanner uses - and a lot of the products (I have on good authority*) are very poor quality.

*One of the “authorities” is myself having been on the receiving end of one of these non-lubricating lubricants during an echo cardiogram investigation a few months ago. The technician began the procedure a second time using and established product - KY Jelly.

You can also try Iso Propyl Alcohol.

Add moisturiser to reduce dryness.

People object to the odour of IPA in more than extremely small amounts.

@johnb by resin I meant acrylic polymers and likewise, didn’t want to mislead.

…what Bill Toge said, and I always admire how Bill is always so politely glib about these things (even when stating the obvious, eh, Bill?) That said - and it IS obvious - we need to answer Avirock’s original question here: there is no realistic substitute for SDA in it’s role in personal care formulation as a solvent, or as a safe-to-use bacteriostat. I mean, you can apply phenol if you want to, but that will get you into trouble. Reminds me of when the U.S. reduced SDA usage in products to 55%, and hair spritz customers would ask “Can you make it so it still dries just as fast?” Me: “Uhhhh…..no.”

@chemicalmatt - well, you can make it dry as fast, you just need to use Propellant 152A which, although it is a volatile hydrocarbon, was exempted from the CARB rules. Tresemme hair spray does this.
