Few questions for the chemists
I have a few questions that I need help with.
First, does anyone recommend a good testing lab for sunscreen products? I’d like to find out the SPF value on two of my products, but I’m not sure I want to go through the FDA and get them registered. More for my companies knowing.
Second, I made a few creams and face washes and after a month of use I sent them to get tested for bacteria. They came back with 1 colony unit, which was normal staph. Is the goal of formulating to have absolutely no bacteria through the life of the product. Is this achievable? Or is it normal to have some bacteria in a product as long as it’s not multiplying?
My third question is, I found this cream on the web ingredients are:
Organic Lavender Water, Organic Blue Chamomile Water, Organic Kukui Nut Oil, Organic Morocco Argan Seed Oil, Organic Avocado Seed Oil, Organic Meadowfoam Seed Oil, Organic Golden Jojoba Oil, Organic Co2 Extractions of Tamarind Seed, Tamanu Nut, Raspberry Seed, Calendula, Sea Buckthorn, Honeysuckle, and Red Radish Root Extract.
How the heck does this cream stay together??? The formulator also says that the ingredients are never heated above 96 degrees. The picture of the cream looks so smooth and creamy. I have no idea how it stays together with out emulsifiers?
