You can also use some zinc/titanium dioxide? but reducing the hemp is probably the best way.

MemberNovember 6, 2018 at 10:40 pm in reply to: CHAMOMILE EXTRACT OR ESSENTIAL OILChamomile Extract is believed to be soothing and calming and since it is a middle note and not a top note like citrus, it is probably a better choice to put in a face cream than harsh top notes. You need to be careful when you choose Essential Oils for the face. The maximum amount is 0.3% Hope this helps..

Herbal and citrus notes can go off relatively quickly!

MemberOctober 19, 2018 at 2:18 pm in reply to: final product separation at the market@marytsiang there is a totally different problem it could be. Have you thought about the formula reacting with the new machinery as you have Alumina in there? What was your homogeniser made out of previously? Also can you put in some more BHT? Or Tochepherol@ 1%.

I think that Vitamin E is all you need and can become part of your marketing story as well.

@mayachem, did you do a real time stability test? That can usually take about 3 months to do properly?

Is Lexfeel naturally derived?

MemberOctober 17, 2018 at 11:03 pm in reply to: body mist have initial strong alcohol smellCome on, if ethanol drys the skin then why is there a multi billion dollar business all over the world trying to find actives & oils to put moisture back in???
what do you mean by many professionals on this site, I don’t believe they could be that silly!!?? -

MemberOctober 17, 2018 at 1:24 am in reply to: body mist have initial strong alcohol smell@Gunther no no why would alcohol be a must for a body spray/mist. Alcohol is very drying right? on the skin so you can just use your EO, solubiliser, some humectant, vitamin E for shelf life and water. You can also add floral waters/hydrosols etc. but they are expensive.
