Thanks for the update!

@Skypirate - You raise a great question. Information about product safety is something consumers can have difficulty finding. However, I would just suggest you stick to reliable sources like people who actually have degrees in Toxicology.
The article you linked to is the Natural News which is equivalent to the National Enquirer. It is a BS publication designed to sell products through fear mongering. And the “doctor” who is quoted in the article is “Leading naturopathic doctor Trevor Cates”
Naturopathic is not a doctor! They are experts in the fairy tale that is naturopath.And even if you can find an actual doctor who makes this claim (I’m sure you can) that doesn’t mean much either. Here are some things you should do when you come across claims like this.
1. Is the person making the claim trying to convince you to buy something in which they benefit from you believing the claim? “Dr” Trevor Cates does. https://store.thespadr.com/ Any claim she makes should be met with a high degree of skepticism.
2. Is the person making the claim an expert in the subject? The Spa Dr claims to be an expert in skin. She got a bachelors degree in English, a masters degree in Psychology and an ND degree in the fake subject of naturopathy. (https://www.linkedin.com/in/trevorcates/) This does not make her an expert in Toxicology which is the subject of the claims.
3. What do the consensus of experts on the subject say? We are all biased. Therefore the claims of any single scientists should not hold more weight than the claims of the consensus of scientists. On the subject of parabens the consensus is clear, they are safe to use at the levels used in cosmetics.
If you remember those three questions whenever you hear a claim about any subject, you’ll be more likely get to the truth.

I’m skeptical they’ll be able to come up with a legal definition of “natural”. It seems much more complicated than a definition of “hypoallergenic” and they couldn’t do that.

What research has convinced you that topically applying bee venom will have any effect as an anti-wrinkle ingredient on skin?

Since it doesn’t actually have any effect, 0.01% is the way to go.

Polyquaternium 11 wouldn’t qualify as natural or organic under any standards I’m familiar with. I’ve never found panthenol to be noticeably effective.
You might try coconut oil.
But quats & silicones will actually work better. If performance is a higher priority than “natural” that’s the route I’d go. If “natural” is what you want then you’ll have to sacrifice performance.

Evaporation causes the product to dry. Without more information, that’s the best I can answer.

Please, let’s keep these discussions civil.
@alihsanyuksel - this forum works best when people ask specific questions.
the article posted is a good start. So is Google Scholar. If you don’t know, this is a search engine specifically for academic papers
-
That’s about the right amount of Guar, although I typically used 0.2%.
What specifically do you mean when you say “my hair becomes terrible”?
-
@PeiHoong - I was referring to non-polymeric emulsions, those based on anionic, cationic, or nonionic surfactants. Polymeric emulsifiers handle salt better.
-
@ethelcurtis - Vaseline is petrolatum
-
What alternatives have you been using?
-
Experiment with different levels of ingredients and add some conditioning ingredients.
Right now you have no conditioning agents in your formula. Adding PQ7 or Guar might help.
-
NaCl typically makes emulsions less stable.
-
What noticeable benefit would you be trying to get by adding the MAP?
If it is an ingredient you add such that no one can tell any difference whether it’s in there or not, you will get the same effect on sales by adding a tiny amount (0.1%).

I heard about this some time back.
http://www.bbc.com/news/uk-39308748And we talked about it on the Beauty Brains. http://thebeautybrains.com/2017/04/can-hair-straighteners-stop-your-hair-from-being-naturally-curly-episode-160/
I’m not sure it is just petroleum based products that would be a problem. Even natural oils could leak into the fabric and build up over time to dangerous levels if the sheets are never washed.

Depends on the company, but a larger corporation will and maybe a smaller company might too.
-
Yes
-
@chemnc - what is your objection to parabens? If someone wants an effective, safe preservative there is really nothing better. If someone wants to give in to unproven, scaremongering, then perhaps it’s worth looking at something less reliable.
Phenoxyethanol (Optiphen) is hardly foolproof.
-
I’ve always found that NaCl in an emulsion leads to instability so avoided it.
-
Welcome to the group! We have chemists from around the world. I think there are a couple from Oz.
@Shree_18 - you’ll find talk about “natural” products here but the opinions will be supported by science which is not the case in many other forums that touch on the subject.
-
Beeswax is not a great emulsifier. You should pick something else but the exact one to use will depend on the type of oil in your formula.
Why are you using Centrimide?
A silicone would help with spreadability.
-
Methylparaben, Ethylparaben, DMDM Hydantoin

You could buy your own Corneometer and set up a test yourself. That might be less expensive in the long run. You can then get friends and family to be your subjects. You need at least 30 subjects to get statistical significance.
