thanks 1Armand2
could you suggest the persent of Dimethicon and Sles ? -
ngarayeva001 said:There are several great watersoluble silicones, some of which are even cationic. It’s 2 in 1 solution. Also they don’t suppress foaming as much as regular silicones.
Thanks ???? but silicon oil is completely different and do alot in conditioning specially during washing feel , may be because it’s not a water soluble ( not washable) .
now i am searching for available emulsifier agent for the silicon oil ? -
I am wondering too ! The formula has a white strange sediments?
-
I have readi am still searching for the emulsifier can do it ?
silicon “oil “ in shampoo -
Still trying to solve the problem

What’s the probabilities of this discoloring,
first time to be happened, i use the same color from a while ,
the only new factor is the source of Alcohol.it is isopropyl alcohol by the way -
amitvedakar said:same problem i am facing. color: Brilliant blue.I think blue color is not compatible.
Strange

LincsChemist said:It’s possible if you’ve only seen this happen with a new batch of alcohol that they’ve added a denaturant that is in some way incompatible with your colouring
Yes ,may be

Try using Benzophenone 4- 0.05% for color protection.
Check the final pH of your product, most pigments are pH sensitive.
I’ve put the Blue NO 1 in pH=9.50, it turned Purple after 12 hours.
I am thinking what will cause very high or very low ph value ?
It’s alcohol and water almost no other ingredients .
it’s not a color change it’s discoloration .
i only change the source of alcohol, the other batches didn’t change the color -
klangridge said:To add to ZivBA’s comment, make sure you test the pH of your blue solution in water and make any pH adjustments before adding to the alcohol - alcohols at such a high percentage will not give you an accurate pH reading.klangridge said:To add to ZivBA’s comment, make sure you test the pH of your blue solution in water and make any pH adjustments before adding to the alcohol - alcohols at such a high percentage will not give you an accurate pH reading.
I will check colour dye PH

@Agate, my client wants IPA specifically as they cant get license to get ethanol. Acrylates C 10-30 alkyl acrylate crosspolymer is ultrez 20 i guess. I added propylene glycol 2%, didnt help.@bahey, i used 4% aminopropanol for neutralising, as triethanolamine or sodium hydroxide didnt work.Why Triethanolamin didn’t work !

MemberMarch 1, 2020 at 7:10 am in reply to: How to formulate 60% IPA based hand sanitizer gelWhen i was trying to increase ethanol concentrations it separates and form a big solid white particles,
Agate said:@Padmavathi, fair enough, I would urge you to use at least 75% IPA, as per WHO guidelines.@bahey 40% ethanol isn’t proven to be effective against SARS-Coronaviruses (or many other viruses), it would be reckless to distribute this as a hand sanitizer. Please reformulate to contain 80% ethanol, again this is as per WHO guidelines.On a side note, Sterillium Gel also contains Cyclomethicone, which I imagine helps give it its smooth skin feel.How Cyclomethicone will be dissolve in the formula ?
what about propelen glycol ?
Still don’t find anything remove stickiness of the gel ,
propelen glycol makes the gel turns to liquid ! -

MemberFebruary 29, 2020 at 5:34 am in reply to: How to formulate 60% IPA based hand sanitizer gelThis is very important topic , please share experience,
sticky feeling is a very common result i have the same ,-acqrylic acrylate 1.5 %
-Triethanolamin to neutralize
- ethanol 40 %
-propelen glycol 2% or more because it seems to reduce sticky feeling .
- perfume plus same amount of tween 20, 1%mixing all ingredients except a triethanolamin .
finally neutralize with triethanolaminThis is my method -
bil7 said:Add synthalen w 400 is suspending agent and not so stick like carbomers but you also make aloveragel suspion with alcohols they are non sticky also add propylene glycol litte and glycerin at 0.1 percent will not results in stickness
Aloveragel gel starts from 10 percent to 30 percent for thickening.
I make my own hand sanitizer. Like this .Many thanks i will try ????

This is how they remove soaping in lotions. Watersoluble silicones do impact foam as well but much less.But because it’s water washable , Doesn’t give the very smoothy oily feel while washing

Oops, too late for me to edit what I wrote! I meant fatty alcohols may have -OH group and generally believed that -OH is the magic to binding/attracting water, but in reality fatty alcohols are too weak to be considered as emulsifier and do not emulsify anything. Having -OH group also don’t make them behave like Glycerol. Too weak. They are “co-emulsifier” instead, kind of like stunt double or reserved player.
When you say BTMS do you mean purely BTMS and nothing else? Not BTMS-25, BTMS-50, BTMS something?
I have no experience with BTMS. As mentioned before I do not get pure BTMS.
If BTAC or Behentrimonium Chrloride, even at 15% is still pretty watery. The sample I made was BTAC and water, nothing else. I am a purist and I do not really do knockout experiment. More like I am extremely curious to know how each one behave individually, by doing this I am directly busting myths and see through marketing rubbish on my own.
I don’t know whether or not it is all right to have that much of any Behentrimonium in leave-on product. The BTAC I tried at 15% was just for hair, it sucks big time by the way. It cannot be used alone like that, bad spreading, end up using more than necessary (my educated guess is since it is cationic it ‘sticks’ to the slightly negatively charged hair and seeming gets ‘consumed’. Anionic tends to be smooth and provides more slip/spread due to same charge repels).
However, BTMS-25 or BTMS-50 is said to be able to be used as it is, mix it with water only, as hair conditioner may be due to the addition of fatty alcohol. I have BTMS-50 but I am not bothered enough to try it out because I am nearly bald. LOL! As for the skin…not good for me in this tropical climate, too rich, too sweaty, too uncomfortable even at very very low concentration. BTAC without fatty alcohol is also too rich, too bad for me.
You want to make a spray, eh. You need emulsifier that is liquid at room temperature. Sorbitan (Span) and Polysorbate (Tween). General rule is if you want sprayable emulsion then you use liquid emulsifier/s, at YOUR room temperature (wherever you reside). I don’t like spray stuff but I use Polysorbate because I use dropper bottle, it is almost impossible to impossible to squeeze anything out should I use emulsifiers such as Emulsifying Wax. If use less of it I might as well don’t use it at all because there is a minimum amount of emulsifier to properly emulsify something.
I do not know what silicone you use but you can use this site (https://www.wholesalesuppliesplus.com/calculators/HLBCalculator.aspx) as your assistant. Might not be accurate due to many variables, at least it reduces much headache and guesswork.
I can’t precisely answer you the ratio as to how much emulsifier to use. I was hunting for the calculation too but to no avail. I eventually understood the reason why. There are many variables.
Temperature could also be the deciding factor. For example the room temperature here is 30°C I don’t need to heat anything much and mixing lipids is rather easy because most things which are solid in room temperature in temperate climate (about 24°C) are liquid here, I never see solid coconut oil in my life except in shopping complex, shops, pharmacies, or places where it is air-conditioned.
Another thing is mixing. Because the temperature is high I do not truly need immersion blender nor homogeniser to make tiny tiny lipid droplets in order to make the most stable emulsion possible. All I use is a pathetic milk frother, nothing fancy and nothing exorbitant!
In order for me to sleep soundly I add Xanthan Gum as stabiliser/suspender.
My very early tests there was no emulsifier needed. If emulsifier is needed it will be way way less than most of us are ‘forced’ to using. The emulsions I made were with sonicator. That device is stupid magical! Never mind the temperature differences as those emulsions appeared to be insanely stable! I don’t know the scientific witchcraft but I do know that cavitation removes air surrounding lipids. Maybe I answered myself.
The exact same effect can be replicated in a vacuum chamber. The deceptive emulsion can then be bubbled, vigorously shaken, and no separation afterwards. Maybe there was separation, might be too small for my demi-blind eyes to see.
how could i add cyclopentasiloxane to this formula without separation problems ?please advice -

what is the maximum Cyclopentasiloxane ratio could emulsified BTMS in liquid solution?

What about using isopropyl alcohol instead of Ethyl alcohol?
