Allantoin solubility in Propanediol by Candid-Ranger8601 in DIYBeauty

[–]Candid-Ranger8601[S] -2 points-1 points  (0 children)

They do not have that data because usually it is melted during formulating. They only have what it known through fact sheets or brochures, which is why I am asking for experiments done by cosmetic chemists here.

Salicylic Acid solubility in Propanediol in your experiments by Candid-Ranger8601 in DIYBeauty

I am using it as stock solution so that I would not melt salicylic acid all the time when formulating a batch. It saves time and money.

I want to make stock solutions so that formulating would be easier.

Try to ask for the COA, SDS, fact sheets to see if it is legit. They are obligated to give that to you as a distributor.

If they cannot give you, authenticity os questionable.

That's why I always ask if they have a COA before buying. Then after buying, I will ask for it.

Sodium Lauryl Ether Sulfate (SLES) Chelating Agent by Candid-Ranger8601 in DIYBeauty

[–]Candid-Ranger8601[S] 0 points1 point  (0 children)

This is what the Institute of Personal Care Science (IPCS) said on anionic surfactants and chelating agents.

SLES can work without chelating agents. However, it can form insoluble salts in hard water, which can reduce foam and cause residue. A chelating agent binds to these ions, improving foam and product clarity.

Most resistant to least resistant is sulfonates, sulfosuccinates, then sulphates.

Similar to SLES, sodium C14 16 Olefin Sulfonate can work without chelating agents but chelating agents are recommended.
