Thank you for your inquiry.
Gloves that are available for use can be seen here. I am not personally aware of any better option than the accelerator-free latex gloves that you mentioned. Most gloves noted at the link below, which are not latex, are intended for those who are latex allergic and very rarely cause problems (although rarely they can).
In summary, the only “natural” non-synthetic gloves of which I am aware are made from latex, and I am not aware of any latex glove less free of chemicals than those which are accelerator-free. The others are, as you know, synthetic.
Thank you again for your inquiry and we hope this response is helpful to you.
