It’s tough to beat Hydroquinone for effectiveness.

@milliachemist - yes, Hydrogen bonding of course. It seems Hydrogen bonding affects everything in chemistry.

@nasrins - the answer to this question is much more complicated than you might imagine. Fragrances are made up of dozens or even hundreds of different molecules each of which can have a different compatibility profile with the solublizer. Polysorbate 80 has a lower HLB value 15 versus Polysorbate 20 (HLB 16.5) so that could have something to do with it. But there are so many other factors that could come into play like the residual ingredients in your formula, the exact amounts you used, and a host of other things that I really can’t give you much more of an answer.
Unfortunately, there is a lot about cosmetic science that hasn’t been thoroughly investigated because most of the people working in the field are looking for solutions to problems rather than answer about the fundamental principles behind subjects. -
Why wouldn’t Titanium Dioxide work in the natural market? It’s a big part of mineral makeups.
-
Typically, a solubilzer is a nonionic surfactant. You should try Polysorbate 20 (or 80). Oleth-40 or something like that.

This is a perfect situation for a formula knock-out experiment.
-
I agree with the above. Could also be the pearl kicking out of solution

This is my best attempt to collect sources for free cosmetic formulas.

I doubt there would be any noticeable difference between the two. Consumers especially are not good at picking up the kinds of subtle differences that there may be.
-
@Bimsmide - you figure out the proper level by doing a salt curve analysis on your system. See this post on how to do a salt curve analysis.

I’m reminded of this image.

@Gustavo - It makes for an easy marketing story. Marketers are trying to find ways to differentiate themselves. The reality about cosmetics is that no one can really make consumer-noticeably superior products. That is to say, no one is able to make cosmetic products that are clearly better than everyone else’s.
So the marketers have a problem. The products won’t make them stand out so they need to find different ways. Some marketers stand out with their packaging, others do it with their advertising. Small companies do it with fear. When you say your products are ‘gluten free’ you are implying that there is something wrong with gluten. And for people who have sensitivities or worry about “chemicals” this is an appealing story.The reason there are gluten free cosmetics is because there are people who mistakenly believe gluten is bad and they are willing to pay money to avoid it. -
Yes, posting your email address in the forum is not suggested. Better is to send a direct message to whoever you want to contact. Just click on the person’s name and choose the ‘send message’ option.

Can you tell us what brand it is?

Welcome to the forum Sarah!

We also used International Hair Importers.

Here’s a decent description of the different caps available. Maybe the orifice reducer cap would work.

What do you want the alcohol to do in the formula?
For preservation you’ll have to use ~20%There may be some California VOC restrictions on using that much in a cream however. -
@Bimsmide - If you adjust the salt to the proper level then no, you don’t need an additional thickener
-
It you want to make a claim that your soap is “antibacterial” at least in the US, it has to contain one of the ingredients listed in the monograph. (see page 34) Lactic acid is not on the list. Neither is tea tree oil, neem oil or extract of thyme.
That’s not to say these things don’t work, you just can’t claim that you are selling an antibacterial soap. -
I wonder (if ultimately the judgment does in favor of the safety of TiO2), the companies will get refunded the money they paid out for the settlement.
) -
@Bobzchemist - thus the reason there aren’t many companies different who make this stuff.
-
The thing I find most fascinating about this lawsuit is that none of the big companies are settling. Why not? I guess they have the money to drag it out?
-
Yes, you can post this message here if you don’t want it to get pushed off the front page.

Half up front seems much more reasonable. You need to maintain some leverage to ensure the product meets specifications. Or at least get some guarantee on what happens with a batch that does not meet specifications.
