I don’t mind the shampoo bars from L*sh. They are basically just pressed SLS pellets though. If you like to strip your hair to squeaky clean and then slick it with silicones they work well!
-
Some polymers provide some pretty good spread also - polyacrylate crosspolymer-6 for example.

@Graillotion I’ll wait to get GSC then, thanks for your advice!
-
Thank you for your response! I’ll grab some GSC when I can and give it a go. This might sound dumb but I have sucrose cocoate on hand (which I think is nonionic not anionic). Could that have any benefit to the formula?
-
@ngarayeva001 okay sounds good! I do find it really annoying to melt - I have to bring everything up to like 100C before it melts completely or it’s just a bunch of sticky blobs.

Okay so I tried thickening squalane and CCT with my silica dimethyl silylate and they both thickened really well. I don’t have any octyldodecanol left to try. I tried to thicken a blend of squalane and CCT with polyamide-3 but even at 10% polyamide-3 it was barely thickened and also very cloudy. So when the gel-balm is in an airless pump it remains together but as you pump it out it almost gets thicker like what settles to the bottom is thicker and heavier? If you are willing to help @ngarayeva001 I can send you the whole formula privately?
-
@ngarayeva001 I haven’t tried polyamide-3 on its own but I’ve used it in combo with silica dimethyl silylate. I’ll try to increase the level of polyamide-3 and hope for the best! It doesn’t seem to ALWAYS separate, just sometimes.

@ngarayeva001 or I also have polyhydroxy stearic acid
-
ngarayeva001 said:It doesn’t perform well with high polarity oils (the one I have is covasilic 15). I tried it in both octyldodecanol and CCT and it didn’t thicken them at all. I have not tried it in squalane, but it thickens hydrogenated polyisobutene. Since those two are both hydrocarbons and low polarity the thickening you see is probably due to squalane. And it is not surprising you see separation. Your oils have different polarities.
@ngarayeva001 Thanks for your reply! If I were to keep the same oil profile and add in an additional oil thickening agent like polyamide-3. Would it likely improve the situation? If not is there anything you would recommend?

I’m asking if the way that potassium sorbate function as a preservative - conversion to sorbic acid etc would work properly when in a dry format like a cleansing powder.
-
@ToddZiegler69 Why not try some light esters instead of oils?
-
I’ve read somewhere about glycerin’s impact on the stratum corneum -something to do with the transition of lipid crystalline structures into liquid states as well as increased desmosome degradation (so better tissue sloughing). If I’m to add hyaluronic acid to a formulation - it would typically be for marketing, not for additional hydration benefits.
-
When I was in school, a few of my colleagues had co-op positions as ‘colour matchers’ where they had to test each batch against the benchmark and then suggest changes based on the observed difference. Due to variation like you said, the formula has to be adjusted slightly with each batch.
-
I’ve actually seen something almost identical in products I was developing. What’s interesting is it only occurred in these small glass jars that I was using because I ran out of any type. I assumed it was that they weren’t air tight and so the cream was basically drying up. Maybe try putting the formula into another container? Maybe the surface is drying out like suggested earlier.
-
What do you mean ‘what have I formulated’?
-
Consumers don’t know that its the electrostatic charge of certain silicone oils (amine-functionalized) that allows them to cling to your hair and make it feel soft so I’m sure they feel that plant oils do something similar.
There’s a product by Olay - the body wash with ribbons or something along those lines that deposits petrolatum on the skin and it does make your skin soft. The question though is whether it’s cleansing the skin.
-
@Perry Thanks!
-
Try MNK Recherche in Montreal - I’ve had good experience with them.

They’re basically lying - probably in the fine print it says something more truthful. Example: https://www.timelessha.com/products/hyaluronic-acid-serum-100-pure#ingredients

I used to LOVE cosmetics but once I went to school for cosmetic sciences I became pretty disappointed in the industry… When I was just an interested consumer and biology undergraduate I thought a whole lot more went into formulation but there’s just a lot of the same with little variation (not always the case but its common enough). I always get really disappointed when I see a product like a shampoo with different variations like shea butter, aloe etc claiming different effects yet they just put a minuscule amount of each and the base formula is the same because they just wanted to claim it on the packaging. I even use way less cosmetic products than before I knew too much!
I remember in one course I took, we were studying actives and I expected to learn HOW common actives worked, like hyaluronic acid, yet we just learned the pseudoscience - it holds 1000x it weight in water and hydrates the skin… okay but HOW? The instructors I had were industry professionals with full time industry jobs. I’m not even sure they knew the answers I was looking for…
I find it exhausting to read the ingredient lists of new launches… rarely is there innovation.. Even if there was, I’m not sure the consumer would even notice unless it had the trending extract in it with the most dramatic claims.

@sameralazzeh Will there be a detectable different in the quality and performance of your soap versus a syndet bar - or is the difference that it’s organic? People already think soap is natural enough - I’m not sure they are even looking for anything more..
-
Wow the SDS on ULProspector for Naticide says “Vegetable origin fragrance, obtained with particular and reserved procedure”. Does anyone know what its derived from or its composition? Bizarre!
-
Wow I can’t believe the list of unacceptable ingredients at Whole Foods. I never checked theirs out.. WOW
-
Isoamyl laurate and coco-caprylate/caprate are pretty light feeling with quick absorption.
-
Best way is to just try it out yourself and see what happens. Nobody can say much without you providing information on the hyaluronic solution and which surfactant and what you are trying to achieve.
