Professional Chemist / FormulatorApril 18, 2022 at 10:09 pm in reply to: Ideas to reduce Natural Hair Gel from flaking?I’d do a knock-out experiment to see what causes the flaking.
Also, the following ingredients could be significantly reduced as they likely have no significant effect.1% Irish Moss extract1% amaranthus extract1% panthenol1% vegesilkFewer ingredients should reduce the incidence of flaking. -

Professional Chemist / FormulatorApril 18, 2022 at 3:36 pm in reply to: synthesis polydimethylsiloxane or dimethiconeI don’t believe anyone on here would know how to synthesize dimethicone. This site is more related to the use and application of existing raw materials, not the synthesis of them.
But you never know, maybe someone knows. I don’t.

Professional Chemist / FormulatorApril 15, 2022 at 1:51 pm in reply to: Need Suggestions & IdeasI agree with @Camel - It’s all about the marketing.
Here are some useful resources.
1. https://storybrand.com/ (Their book is pretty good)
2. https://ducttapemarketing.com/ (I like this guy’s stuff a lot)The most important thing to do is to figure out why you are different than all the competitors and who your audience is. Then email marketing & advertising does the rest.

Professional Chemist / FormulatorApril 12, 2022 at 3:07 pm in reply to: Hotact with emulsified sugar scrubsIt helps to understand why Vanillyl Butyl Ether causes a heating effect.
It comes down to hydrogen bonding. The VBE has a free -OH group. When it is mixed with water, the lower energy VBE hydrogen bonds replace some of the water-water hydrogen bonds. Since there is now a reduction in bonding energy, the extra free energy has to go somewhere. That means it gets converted into heat for the system. Thus it heats up.However, if there is no hydrogen bonding going on in your system, like one that doesn’t have water. No extra heat will be produced.
Bottom line: Without water HotAct holds on to it’s “heat”

Professional Chemist / FormulatorApril 11, 2022 at 3:21 pm in reply to: soap free products@Camel - We can only guess, but I suspect the first soaps were derived from animal fat (tallow). When cooking over a fire, the fat may have dropped into the wood ashes where the saponification reaction might occur.

Professional Chemist / FormulatorApril 11, 2022 at 2:44 pm in reply to: Axe Body Wash dupeShould be easy enough with the right fragrance and right solubilizer.
I’m sure the folks at Unilever worked closely with the fragrance house to get the right fragrance that was compatible with their base formula. -

Professional Chemist / FormulatorApril 9, 2022 at 7:07 pm in reply to: Confused on the need for oil based cleansers, surfactants from water based are emulsifiers for oil?Dirt on your skin is composed of oils.
Water by itself does not remove oils.Surfactants can surround oils, lift them off the surface where the oil can be rinsed away.Now, not all surfactants can remove all oils. Some are better at it then others. So, it’s possible that even after using a cleanser on the skin there may be some oils left. It’s like when you are painting and even after washing your hands some paint may remain.
So, if you put an oil on your skin this may be more compatible with the oil that was left behind. This can help lift the oil off your skin. You can’t rinse it away with water but you can either wipe it away or use a second step cleanser that can now remove the more easily removable oil blend.
Whether people need an oil cleanser or not is debatable but there is some sense in using them.

Professional Chemist / FormulatorApril 5, 2022 at 3:13 pm in reply to: sunflower oil qualityThe linoleic may have some stability issues more quickly than the oleic since there is an extra, less stable double bond, but from a performance standpoint, I doubt you would notice any difference.

Professional Chemist / FormulatorApril 5, 2022 at 3:11 pm in reply to: Can these be labeled sulfate-free?I suppose companies wouldn’t do this type of advertising if it wasn’t effective. Fear marketing exists because it works. Consumers should share some of the blame.

Professional Chemist / FormulatorApril 1, 2022 at 9:42 pm in reply to: Is Niacinamide Effective in Rinse-Off Applications?It is very difficult to demonstrate that a certain ingredient is actually having an effect. If you are also using a moisturizer or other products after cleansing, all of the effects you’ve described could be attributed solely to those products.
In my view, it’s highly unlikely that a water soluble ingredient like niacinamide & panthenol are having any impact at all when delivered from a cleansing formula.
Why don’t the detergents and water in the cleanser simply wash these ingredients down the drain?

Professional Chemist / FormulatorApril 1, 2022 at 7:35 pm in reply to: Can these be labeled sulfate-free?The Honest company got in trouble for claiming their detergents which contain Sodium Cocoyl Sulfate were Sodium Lauryl Sulfate free. They even doubled down on this claim. But in the end they had to pay a fine settling out of court without admitting any wrongdoing.

I use all three for mostly research. UL Prospector has been most useful to me. They’re great for getting starting formulas. Knowde search is better but also it feels like a bit of a mess to me. I haven’t really explored Covalo much since they changed over from being Chemberry

Professional Chemist / FormulatorApril 1, 2022 at 12:42 pm in reply to: Can these be labeled sulfate-free?Behentrimonium methosulfate is a sulfate from a chemistry point of view. If a lawyer decided to sue you what would your defense be? I understand that it’s not the same as SLS or SLES but I don’t think you should claim sulfate free if you use that. It will also confuse consumers since the word sulfate is literally in the name.
The sulphonate is fine to claim sulfate free because it is.

Professional Chemist / FormulatorMarch 31, 2022 at 2:31 pm in reply to: Is 2% salicylic better than 5% or even 2.5% benzoyl peroxide for acne as said here?@grapefruit22 - yes, those are the kind of objective measurements you could take. But of course there are numerous complications. For example…
1. How big does something have to be to count as an acne lesion?
2. How do you compare the size of two differently shaped lesions? They’re not all perfect circles.
3. What’s the expected healing rate of lesions verses an improved rate?
4. What is a level that anyone would notice?and on and on. It just gets complicated.

Professional Chemist / FormulatorMarch 31, 2022 at 12:50 pm in reply to: Is 2% salicylic better than 5% or even 2.5% benzoyl peroxide for acne as said here?Objective means you measure some characteristic with a device. For example you measure the length of something with a ruler. Everyone who does it should get the same result (theoretically)
Subjective means asking people their opinion about some characteristic. For example instead of using a ruler to measure distance you just ask people how long they believe the length of something is.
when there is a definitive characteristic to measure an objective measurement is better. But when the characteristic is less defined like whether a treatment works or not, there are only subjective measurements you can take.
Again you haven’t usefully defined “working”. You’ve just used another vaguely defined word. What does “healing” mean in this context? How would you measure “healing”?
Look at it this way. You have two treatments. What experiment would you run to determine if one worked better than the other? What specifically would you measure to show one thing worked better than another?

Professional Chemist / FormulatorMarch 31, 2022 at 12:11 pm in reply to: Is 2% salicylic better than 5% or even 2.5% benzoyl peroxide for acne as said here?@Abdullah - your question is a subjective one though. What do you mean by “works better”? Works better at doing what? What would it mean if one treatment was working better than another? How would you test that in a measurable way?
The only way really is to ask patients if they believe their acne is getting better.
