Respirator
A good respirator with filters specifically for Organic Vapours will make working with these chemicals easier.
Respirator
A recommended Respirator would be the Moldex 7000 Series Reusable Half Mask Respirator link: https://www.moldex.com/product/7000-series-half-mask-respirator/ Note that we sell smaller disposable dust masks, not these.
You should purchase a filter for organic vapors such as the Moldex #7300 Organic Vapor/Acid Gas Cartridges For 7000/7800/9000 Series Respirators link: https://www.moldex.com/product/7000-7800-9000-series-respirator-organic-vapor-acid-gas-cartridge/
You don't have to go with Moldex. There are similar products from 3M. Likely any well known name brand will offer adequate protection. I would recommend buying from official distributors for a product like this. It is not worth cutting corners for a proper respirator.
Tips/Techniques
Safety Goggles Fit Better Over A Respirator Than Glasses
These respirators, while very good, are not designed for use with traditional safety glasses you might find at the big box hardware stores. The seal around the cheeks and nose may cause a slightly off fit (depending on the safety glasses of course). This means that there is more of an opening for debris to get into your eyes. Usually the glasses are offset slightly high, causing the bottom opening to be unacceptably large.
See the page on Safety Goggles for more details on the proper Goggles to purchase.
