@LincsChemist so .3-.4% Acrylates/c10-30 will work to thicken?
Can I still use Triethanolamine to neutralize at 70% ? I have that already.
-
@Bill_Toge adding more didn’t work. It just glumps into white blobs.
-
@Bill_Toge I will try adding more.
@LincsChemist Acrylates/c10-30 is double the price. What about Carbomer 980?

I’m seeing the caffeine concentration being about .00088?

The viscosity on my past patches had been slightly low so I had reduced the water ratio by 2% which seemed to work well. But these latest batches I had to go to 101.6% of what the water in the thinner batches use to be in and it still is thicker than it should be. The top has a firm layer where the normal product is soft to the touch.
I measure to 1/10th of a gram and the only thing that has changed is the supplier for some of my emulsifiers, namely peg-100 glyceryl stearate and steareth-21. The old company went out of business.
Has anyone ever experienced emulsifiers providing different consistency based on the supplier?

@perry @Belassi
Thank you, I am use to mixing hair styling products that you want mixed “aggressively”. Will try turning down the rpm and let sit.
-
Good thought, I will look into that.
Also, when using smaller batches I heated the water in a microwave, and with larger batches I used a double boiler on the stove top. Both are covered with plastic wrap and measured to the gram. Could the form of heating (microwave vs stove top) affect the mixing and cool down phase?
-
Is it heated? Heat will affect flavor depending on how long/high it is heated.

@Belassi Yes, shampoo is supposed to foam. but if I am making a gallon of shampoo and mixing at a high rate it turns into all bubbles and overflows the mixing container after it has been agitated for emulsification. It is also difficult to pour a pot full of bubbles into individual bottles.
-
Crushing the SCI did help with dispersion, but i am having issues with foaming during the mixing process. How do I mix/emulsify without foaming?
-
@MarkBroussard: thank you!
So what would be the differences between those and other surfactants like the ones listed below?
Sodium Lauryl Sulfoacetate
Decyl Glucoside
Coco-Glucoside
Disodium Lauroyl Glutamate
Disodium Laureth Sulfosuccinate
Sodium Lauryl Sulfoacetate Flake

@ngarayeva001 That’s great to know. Thanks!

You would need to list the full ingredients including oils for anyone to be able to help. I would suggest finding an online HLB calculator and input the % ratios of the oils you are using. A good calculator will tell you what hlb is required for your formulation, then you will need to mix emulsifiers to get that required hlb.It’s kind of like averaging in math. If you need an hlb of 8 but have emulsifiers with hlbs of 15 and 4 you need to mix them together so they average out to 8.

@MarkBroussard, thank you, I will be trying that in my formulations. I will need to wait several months to see how the products age.Thanks!
-
Thank you for the input.Without changing my phases I added more emulsifiers to the ingredient list and the emulsion came out very strong. But I always want to learn and improve! Can you help me understand why you suggest changing the phases the way you listed? How would it impact the emulsification process?
-
Putting all ingredients except water and PVP/va in the oil phase, that goes in after water is mixed in.Think I’m going to add ceteareth-20 to the mix and see how that helps.
-
oil phase heat to 170 melt all ingredients and mix thoroughly
water heat to 170+
mix water and oil phase
I tried adding more emulsifiers but still no results…
-
Regarding Ebay, I purchased an overhead mixer like the one below and it has been great.. However it is double your budget. But off ebay and had no issues.
-
Thank you both. This one was not a blister package.. but I figured I would have to list ingredients.
@ozgirl: Lip balms are only considered drugs based on the claims you make about them. If you claim they “heal” or “protect” FDA will label that as a drug. Otherwise it can be classified as a cosmetic.
-
@ Bill_Toge and Dirtnap1
It sounds like both are very heat resistant. I may try adding the pvp/va in the water phase next time instead of the cool down phase.
Thanks!

@Belassi - I understand there will be evaporation with any hair product. What I’m trying to describe is that the shine of the product does not last.
-
Hand-rubbed test is not accurate, the texture is currently perfect. The problem is after 30 minutes in the hair it dries out.
How will mineral oil keep it from drying in the hair?
-
I would suggest to try putting ingredients in the oil phase. Except solubilizers put those in the water phase.
-
I am considering using acrylate copolymer to add a bit of water resistance to the formula.

Belassi- That’s why I was asking. I have been trying to find info on the clays, but all the property info I can seem to find relates to skin or hair cleansing, not hair styling. Any suggested resources for info on clays for use with hair styling?
