I haven’t seen a lot of research on this subject but I would guess that W/O would significantly hinder the absorption of any ingredient in the internal water phase.
In truth, I doubt there would be any noticeable difference as it’s already pretty difficult to get penetration of those ingredients you mentioned. Hyaluronic acid and panthenol just are too big to penetrate to any significant amount. -
I’ve always found the beads to be total gimmicks anyway. There is no evidence that they made products work better, at least no evidence I’ve seen. I agree! Keep the beads out of the blowfish.

Great idea @Bobzchemist!

I would also suggest looking at the local SCC chapter websites. I know the Midwest SCC chapter has a few open job listings which might be appropriate for you.
Here is the complete list of chapter websites.Here is a list of all the chapters and websites for the SCC around the country including 2 in Canada.
California Chapter
Carolina Chapter
Connecticut Chapter
Florida Chapter
Intermountain West Chapter
Lake Erie Chapter
Long Island Chapter
Michigan Chapter
Mid-Atlantic Chapter

And even if we had the full formula, you still need to run the microbial challenge test to verify.

Hello @gabo,
Indeed these come from me. Unfortunately, I had a website crash a couple months ago and that screwed up the whole Cosmetic Launch Coach program. I’m trying to get it back up but it won’t be ready until about May.Thanks for letting me know as I didn’t realize some of the links in the emails I sent out weren’t working.Perry, 44 -
Aloe gel or Aloe juice is >90% water so it won’t matter much. It would essentially be the same as using water.
A Polyquat could help aid in reducing frizz but a silicone might work better. -
As a user of private, for-profit health care in the US I don’t think you’re missing much.

No problem @Rahma. Thank you and everyone else for participating.

It’s for the EU since the terms Aqua & Parfum are used and they list the fragrance allergens.

You can find formulas in the following resource.
There might be some laundry detergent formulas in there.Just realize that when you ask for a formula there are chemists here who make a living out of coming up with formulas so it’s unlikely that anyone would just give away something that they’ve spent years of their lives developing. It would be like asking a famous pastry chef for their best cake recipe.I’m certain there are people here who you could hire to come up with a formula like the one you described.

I don’t know about the speed of kojic acid dipalmiatate but I’ll comment on the others.
Argan oil - what do you mean by “anti aging effect”? Argan oil has not been shown to have any effect at all for reducing wrinkles, firming skin or removing age spots.Collagen firming. It doesn’t. Applying collagen topically has not been shown to have any noticeable effect on skin firming.Sorry I couldn’t be more helpful but science is science.If you’re more interested in the marketing angle then you can put the ingredients in the formula at a concentration of 0.1% (or 0.01%) and play up their effects in the marketing story. -
I was always a fan of Glycol Stearate. It’s just fun to see the pearl develop.
And Carbomer 940. Sure it’s a pain to get into solution but the cool, stable gels you can make are unmatched.My go to preservative is DMDM Hydantoin. Not popular in some circles but it’s the most effective one I’ve seen. -
Interesting question. It’s hard to answer because I don’t know what kind of advise you are supposed to give. Formulating advice? Sales advice? Marketing advice?
I’ll assume formulating advice. For this I would suggest the formula should be light feeling and non-slippery. You don’t want it squishing around in someone’s sock all day. Also, since the foot would be covered you don’t need to include heavy moisturizers like mineral oil or petrolatum. And avoid humectants like glycerin because you don’t really need any more moisture than the feet are naturally going to produce. Mostly you want a product that will make the skin feel softer. Including tea tree oil might also help as it could “naturally” fight some of the foot microbes. It will also give a significant odor so that will have to be compensated for by using a fragrance.Perry, 44PS. What cosmetic science course are you in? -
Fix a stability problem that shows up 1 month later in 2 days? Now that’s a real challenge.
It’s difficult to give you any suggestions without knowing what is separating. From what you describe it could be the fragrance separating for which I’d suggest you use some kind of pre-solubilizer like Polysorbate 20 or 80 or something.But without knowing more information the best advice I can give is to increase the amount of surfactant you have in the system. It’s not great advice but it’s the best I can give based on the information I have. -
That sounds like a great idea @KenWiener! Welcome to the forum.

Hello @greenwave (Maria)! Welcome to the forum.

7. Hiring a cosmetic chemist consultant to create the formula. Have someone else produce it.
-
I figure it would cost between $10,000 and $15,000 US. This depends on what type of product you are launching and the type of package you want. Probably the least amount would be $7000 (unless you have some sort of “free” resources)
-
I think a general principle is that you make more stable emulsions if you use multiple emulsifiers. Whether you can do it with one ingredient doesn’t mean you should.
But thanks for the info! -
Welcome aboard everyone!
-
I don’t have an answer to the question but 5% vitmain E acetate? What is it supposed to do in the formula?
Carbomer would be a good suspending / thickening system. -
That really depends on what is in the rest of your formula. Can you at least provide an ingredient list?
-
Of course it depends on what you mean by natural but you can try coconut oil.
-
Yes, we used glass-lined equipment.
