Hi Hazel,
It could be that the manufacturing processes have changed ... thanks for that information. I know it's an approved ingredient, for instance, in ice cream, etc., but there are still some issues with it, possibly not from a dermal usage standpoint, but I can't be sure of that exactly. From what I understand, it is being used in a flu vaccine and has been noted as possibly causing infertility. I guess there was some study with mice, which seems to be noted in various articles.
As I said, I'm not sure what the risks would be when applied to the skin over and over. In my case, with what I make, I need to stay clear of it regardless.
If interested, here is a little info. on it in regard to these issues:
"Polysorbate 80 probably induced a skin tumour in a mouse treated repeatedly by the dermal route."

In oral and skin painting studies in mice, it increased the yield of tumours induced by established carcinogens.

According to Annals of Allergy, Asthma and Immunology, Volume 95, Number 6, December 2005 , pp. 593-599(7), "it is of current relevance as a 'hidden' inductor of anaphylactoid reactions", and "Polysorbate 80 was identified as the causative agent for the anaphylactoid reaction of nonimmunologic origin in the patient. Conclusions: Polysorbate 80 is a ubiquitously used solubilizing agent that can cause severe nonimmunologic anaphylactoid reactions."

just listed it so you can see that there are some
studies on this in regard to these issues.

So, it may not mean anything to us using it in body products ...
or, could it? I don't know, but there's some info. about it anyway,
for what it's worth!
