I really like Prospector. There I can always find technical information, INCI as well as starting formulas, so it always come in handy when I’m developing new formulas.

SpecialChem is nice too, but is more simple information (INCI, general ingredient description, concentration of actives, solubility).

Hi Rockstargirl,

Thank you so much for your comment! It was incredibly helpful. I’ll be conducting some tests with Agar as suggested, as well as with the combination of oil and a carbomer to see which best suits the result I’m aiming for. I’ll be sure to circle back soon to share the findings from the tests.

Thanks again for your valuable insight!

Thank you, Zoya! In the next few weeks I’ll be testing it out in the lab.

Oh, that was a class!

Thank you so much for your thoughtful answer, Perry!

Hi there!

The final pH is around 4.

The Hydorxyethycellulose isn’t coated. We’re using Cellosize from Dow.

Unfortunately, I don’t know the pH of the benchmark (but I assume it’s acidic - around 3.5 - 5.0).

We added the solubilizers to facilitate the salycilic acid incorporation.

Hey Phil! No, I’m not in the US, I’m from Latam.

Here in the company that I work in we usually use this preservative blend in almost every system that we formulate and never had any issues with microbial growth/contamination in general.

Hey!

Probably the hydrolyzed proteins and preservative system don’t work well in your formulation; they’re causing incompatibility.

The most practical decision would be to change the hydrolyzed proteins and preservative system. Overall I like to use Microcare PHG (which is a caprylyl glycol and phenoxyethanol blend). Also, would it be possible to change the hydrolyzed proteins for other ingredients? Aminoacids blend or plant extracts would do the job 🙂

Interesting! Thank you.

I think it depends… In the case of biphasic makeup removers, for example, I think the oil phase can facilitate the removal of waterproof makeup, and the water phase can facilitate the removal of water soluble residues and turn the product less heavy, as well. But in other cases is more of a marketing thing. In my case, I’m developing a hair mist and it being biphasic is more of a marketing thing.

Thank you, Bill!

Didn’t know that about Benzyl Alcohol. Interesting!

Thank you, Matt!

This is exactly what I thought; it is used to destabilize the system. I’m using it now at 0.4%.

Thank you for the heads up, Matt!

Why CETAC is not advisable in this situation? I’ve thought that I could achieve a good conditioning effect using both.

Thank you, Mark!

I’ll try to conduct more research on this topic. 🙂
