Also considering our dollar is so crap at the moment, it might just be a wise decision to have it developed and manufactured here. Why not??

Perry is right, although in Australia if you are doing a tint, the sunscreen can be labelled as a secondary ingredient. Therefore, no tests need to be done!

Sorry but are you guys serious?? anyone can do anything if they are passionate enough even if you are living with a narc.You guys are going about this whole process the wrong way and I would be so put off. Obviously, this business owner has been quite successful already and wants to expand on his/her success.Starting with a Hyaluronic Acid Serum is a great place to start and you can do it either naturally or synthetically that is just detail these days.Plus you do not have to have a point of difference if you use a formulator. The formulator should be able to do that for you. Have a think about that guys??

I know one popular cosmetic ingredient that does work, don’t think you would call it an extract though! After I had my first baby her behind came out in a big red rash, normal I was told. So I slathered on a ZnO laden cream & guess what? No red bottom next day! It’s the only anti inflammatory I know that works, heals sores even on your face. Put it on at night & it’s a million times better than any of the expensive treatments. I have tried nsaids, herbs like Arnica etc. Actually the only other compound that works is Salicylate we call it dencorub! Which also contains menthol for the cooling effects??
Thoughts? -
@singal also I would never send you a sample that was someone elses or one sitting on the shelf, its custom all the way.
-
Maybe your pH is too low for your face, how long do you leave it on for?? 4.4 is a bit low for me! Hope this helps

Hi @singal I am a private formulator and I do a lot of natural and organic formulations which has taken quite a few years, even though it seems easy.Here are the pros- lower cost, own formula, you will get me rather than a graduate, a lot more personal communication like you can ask questions whenever you want, I take on the funky formulas that no one else with do ( I think this is on purpose LOL), I let you have any ingredients unless they are from outer space. I guess I hold your hand from the start to finish if you want so that is a big difference! Hope that helps Catherine Pratt from Dr Pratts

You are allowed to buy any polymer from anywhere as long as its for sale!!
-
Other emollients like C12-C? Benzoate, Isoamyl Acetate, for people with sensitive skin try using ingredients that do not produce fatty acids as bacteria that grows on the skin and make it red and turn into patches etc can come from various bacteria. In fact if this is a large point for you use a wax also like parrafin wax. Parrafin will reduce cost too and mineral oil, there is a naturally derived vaseline type ingredient now.Also have you tried dimethiconol? its just dimethicone with a hydroxyl group built in to make it more water friendly.
-
BTMS 25 and 50, Glyceryl stearate citrate, mono glyceride 40, cross polymer, there are loads
-
Maybe use some well known emulsifiers primary and secondary. If the ingredients lists use no go ingredient like Na Benzoate like Perry was talking about, these ingredients could have come from ingredients they have used that already were preserved with that ingredient. Does that make sense? Like a hydrosol for example.
-
Drop the MG stearate just use the zinc stearate to start with
-
If you are just doing it at home you can just use a coffee grinder, I’ve used the Sunbeam one touch usually for herbs and beans.
-
Thanks for your information on ingredients in natural deodorants. Beeswax and arrowroot would give you pimples. Maybe you should use some lighter materials if you wanted to reformulate and still make your own.
-
If you only use a small amount to gelling agent, maybe Chia Seed Oil?
-
Hydrolyzed Rhodophyceae Extract is an Anti-pollution Active

what about using natural Silica powder? plus bicarbonate or white kaolin as the abrasive? Your pH should be around 8 for toothpaste, 20um particle sizes, you can get just a small coffee grinder to grind the powder for R&D sizes. Titanium is a good whitener, a natural mineral as well. You can also use Tapioca, Starch etc. I put the powders in at the end. You can raise the pH by using NaOH and buy yourself a pH meter that you can calibrate. You can buy one on Ebay. I have even put beeswax as a consistency factor so of course you can put shea butter in. You just need to keep experimenting. Yes you will throw away a whole heap of material along the way but that is all part of the process.Honestly, I would not use Diatomaceous Earth, but many people do, that is just my opinion.Also if you add a surfactant for foaming, that will raise the pH anyway. A mild surfactant like Decyl Glucoside is an oldy but still OK.

Doesn’t oil free really mean they are talking about silicones? Originally!
-
Science based formulas are great and becoming more and more popular, even in the natural arena. References to clinical studies are still ‘Claims’!
-
The first thing I ask clients is ‘What is your point of difference’?, you need to do some research and figure out what will make your product sell above any others. Then you will have some direction.
-
Yes I agree, Texapon is still a common ingredient as well.
-
I thought it was the glutamate, what research do you have?
-
Less irritating??
-
Yes I am sure we will find out within time! The reason everyone is going mad for it is because you can put it in your lotion and walk outside in the sun with it, and as you know you cannot do that with the real retinol!
-
Have you tried the retinol alternative, Bakuchiol?
