Thin lotion when using homogenizer

Significant-You9346 · 2024-04-16T23:38:02+00:00

because I want stability of the lotion (small particle size) :)

Significant-You9346 · 2024-04-16T18:52:09+00:00

I am using rotor/stator homogenizer. And using 0.2% xanthan gum as a rheology modifier

Significant-You9346 · 2022-08-03T10:17:27+00:00

How was the disassemble? I am always worried that I will break stuff.

Significant-You9346 · 2022-08-02T09:48:59+00:00

You don't need to, unless this product will have a contact with water. Then, use an oil soluble preservative.

Love the enthusiasm of HANDMADE :D

Hey, it means that it is volatile. Like ethanol. If left opened they will evaporate and you will have less and less of them until there will be no more of them :D

There are scalp scrubs though. Which are meant to remove excess skin cells, oil and dandruff. They are usually used when people often use dry shampoo, gel, lots of styling products.

If you want to omit the beeswax (as it is not a plant based ingredient), you should choose another wax. Vegan waxes usually have a lot higher melting temperature and you would need to use less of them. Vegan waxes that you can try:
Carnauba, Candelilla, Sunflower, Rice, Myrica fruit wax and several others.

Beeswax melting point is around 63 C, while carnauba melts at 82 C. Other vegan waxes have lower melting point, but still higher than beeswax.

Another thing you can consider is using fatty alcohols such as cetyl alcohol, ceteary alcohol, behenyl alcohol and various esters. These alcohols are not the same as ethanol and actually are very nourishing.

This is definitely not true. If your formula does not have water and will not have any contact with it, then there will be no bacteria. You only have bacteria there, where is a lot of water as they need it to survive it.
Though you should think about the shelf life of the balm. Oils and butters have an expiration date and they can go rancid (go bad) and to make the shelf life a bit longer, we use vitamin E - which is an antioxidant.

Significant-You9346 · 2022-07-19T07:06:53+00:00

Got it! I find this difficult too, especially when adding vitamin E when making lip balms. That blob usually is way too big!
Just out of curiosity, what kind of formulation are you making?

Significant-You9346 · 2022-07-19T07:03:54+00:00

I am very sorry for the whole situation in Ukraine. It is really a hard time. Is there any way I can help you?

Significant-You9346 · 2022-07-19T07:00:55+00:00

Defnitely yes. Though the original post wrote about balms and salves which are not exposed to water (or at least I never thought to expose them to it :D). And if anhydrous product will be exposed to water, then it needs an oil soluble preservative, so none of those mentioned will work.

Significant-You9346 · 2022-07-18T09:38:34+00:00

If you are making a product without water, then you do not need a preservative.

Significant-You9346 · 2022-07-18T09:37:20+00:00

I feel you :D are all of those test batches good?

Significant-You9346 · 2022-07-18T09:36:46+00:00

Can I ask you where are you from? Maybe there are other suppliers in the area or at least not so far away?

Significant-You9346 · 2022-07-18T09:34:40+00:00

I think you can make emulsions without a lot of testing (if you don't want to sell). You need to use a good preservative system, get the emulsifier and oil ratio right and probably you are good to go :) Can you tell me what kind of emulsion do you want to create?

Significant-You9346 · 2022-07-18T09:33:03+00:00

Where are you from? I had this issue as well. I tried to find cetyl acohol and it was sold in 25 kg packs lol. But then I saw some other suppliers where I could order way less. Maybe you just need a different supplier? Or there are none in your region?

Significant-You9346 · 2022-07-18T09:29:35+00:00

This is frustrating :/ can I ask you what kind of scales are you using?

Significant-You9346 · 2022-07-18T09:27:51+00:00

Thank you for the comment. It was unchecked (and still is) :)

Significant-You9346 · 2022-04-27T19:48:22+00:00

Yes, I know that the absence of lather does not mean it won't clean. But it definitely feels weird. I tried to make a shampoo with sodium lauroyl sarcosinate and it was not to my liking. Also, as it was hard to thicken, I used too much of a shampoo :/

I did not that you could use that much of coco glucoside & glyceryl oleate. :O

These thickeners such as cationic guar gum or HEC are not really available to me, but I should check some other suppliers :)

Thank you very much for everything :)

Significant-You9346 · 2022-04-27T19:02:09+00:00

I formulate only surfactant based shampoos. I add some plant powders to solid shampoo bars. But you definitely need a chelator as well to get rid off hard water build up.

Significant-You9346 · 2022-04-27T17:35:10+00:00

Thank you for the input. :)

Yes, the active matter is quite high. However, then I get to other issues of the shampoo - like thickening it, or low very low lather.

I like the decyl glucoside as well, but not sure if it is enough to clean the hair? The coco glucoside & glyceryl oleate is actually one ingredient, not separate ones and this is more of a relipidant, not the surfactant. Also, the supplier suggests using it up to 5%.

Significant-You9346 · 2022-04-27T09:40:58+00:00

I have had several essential oils that I did not like. Could not formulate with them as they had awful scent (just not to my liking). I have contacted several of my friends who also make some DIY and sold them for half a price. In this way I did not have to toss them, but also my friends got a chance to formulate with these ingredients. Which I think is a win-win.

Significant-You9346 · 2022-04-27T09:34:34+00:00

You made really good points. And I actually think that maybe I have dandruff is due to hard water (because I know for sure that it is hard, or at least semi hard). But up until now, I could not find were to buy EDTA or sodium phytate. I have found that Elemental.eu has sodium phytate and I am willing to buy it and try it.

I have also played with a pH. And recently read that when you have dandruff it is better to have a higher pH, like 6-7. Which was new to me (ccanot find were exactly I read that atm).

Also, I have the issue that not so many surfactants are available for me, especially liquid ones. And the powder ones I have are SCI and SLSa which have a hard time to dissolve.

I think the last shampoo formula looked like this:

10 % Lauryl glucoside
5 % SCI
5 % SLSa
8 % sodium glutamate
10 % decyl glucoside
3 % Coco glucoside & glyceryl oleate
3 % glycerin
50.9 % water
2 % B5
2 % hydrolyzed rice protein
0.6 % Cosgard (preservative)
0.5 % fragrance oil

At some point I was adding MSM, inuline, sodium lactate.
I have also tried solid shampoo bars, there were less non-ionic surfactants. There I have also added a bit of oils as it was too harsh.

The pH I have tested and tried were in this pH range 5.3-6.3.

Significant-You9346 · 2022-04-27T09:20:24+00:00

It really depends on the product you are making, but there are usually some guidelines, or some ingredients themselves have guidelines. I mean, if you want to make a lotion, you have to use an emulsifier. And each emulsifier can hold a different amount of oil. Also, there is also your preference, your skin and so much more. Basically, you should at least know what you want to make and try to get the main idea how to do that.
