Acusol and Opulyn are emulsifiers and the fatty alcohol wouldn’t work as an opacifier.
Do some trials and better have a first hand info.Cheers
-
You want to use it as an opacifier or a film former??????????
I feel that Opulyn might (very remotely though) feel heavier compared to Acusol OP305, but try it and see it for yourself. I might be wrong too.PS: Opulyn is more viscous compared to Acusol OP305, so you might look at percentage also in the formulation. -
You can try Acusol OP305 as well, I use it for my very high pH products. So I am sure the formulation seems to be fine to accept this as an opacifier.
Though I am still unsure what you mean by durability here??????????? -
Hehehe we had a similar issue few years back with Imidazolidinyl Urea and Triethanolamine, but we are still safe.

@Bill_Toge
Thanks Bill I was just wondering that only, was a bit concerned about the tertiary one too. -
Increasing waxes I suppose won’t be of as much help as increasing the percentage of the polymer in the formula.
@ gfeldman Try heating a carbopol gel to 70°C or above and you would see it for yourself the strength of the gel network. Accordingly you can make your decision.Cheers

Fragrances have carriers like DPG, DEP and they are made up of so many ingredients (generally) that you cant define the fragrances in general. Every fragrance has a different composition, ethanol is seen with fragrances generally in finished products only. I am not an expert but this is what I have seen and learnt during my work experience.
Perfumery itself is an entirely different discipline to learn.Cheers

@Ajm Think it has been clarified in some other posts too that the crystallization of the fatty alcohols that takes place over a period of time has been nipped in the bud by the magical herb used by you.
-
Generally it is the pigments which have heavy metals as impurities.
-
@tonyh Always a pleasure to have extra topping with a regular order, your comments just cleared up so many doubts which were not even raised here.
-
there are studies stating that the efficacy of climbazole is enhanced if used with another agent, but again it all comes down to the cost and final formulation type. Or you might like to optimize the efficacy of one ingredient only with the right selection of formula and its parameters.
And thanks for the jibe @nasrins -
@tonyh generally Piroctone is preferred for clear shampoos whereas ZPTO we all know is a fav ingredient of so many anti-dandruff recipes and which are quite obviously opaque. So the nature of formula has to be considered I suppose. Please correct me if I m wrong.
-
@miko Think you should try to achieve the optimum pH (read recommended) to gain the viscosity if your electrolyte has failed to live upto the expectations and as pointed out by tonyh. As I have read in some literature of this soap, it needs a working pH of 8-9 for optimum efficacy and for clear formulas. Maybe this piece of info can be useful to you.
Cheers

@vitalys I noticed this in my normal salt based shampoo when I added DPG and it became water thin.
-
IIRC few days back we had a query (on chemistscorner.com) for Caprylyl Alcohol being used as a preservative but overall reducing the emulsion viscosity as well. So I suppose this is where it can come into play as a preservative plus viscosity regulator in cetyl alcohol based emulsions. Maybe disrupting the formation of crystalline structure, who knows!!!!!
This means certain other glycols can be used as well to regulate the viscosity in emulsions if incorporated and chosen wisely. -
That purity part makes it all too plausible, indeed how we say it - self explanatory.
Thnx @Bobzchemist
-
When you say that Behenyl Alcohol should work better, does it mean that in this case as well the chances of crystallization exist??? Like Cetyl this is also a saturated alcohol and with a longer C chain, or the curious case of Cetyl differs from formula to formula???
-
@Bobzchemist Very interesting and useful link.
-
I have read in some article that single fatty alcohol would crystallize more compared to a mixture of fatty alcohols. A mixture would give you a more amorphous and stronger structure, this was pertaining to some candle patent but I am guessing that it might be applicable to emulsions as well.Though I use a mixture of fatty alcohols in my emulsions but honestly never ever thought of this crystalline and amorphous part.Correct me if I err.Cheers
-
@DavidW I think in many more discussion previous to this, it has been pointed out by many learned chemists here that Cetyl Alcohol is the main culprit which leads to this thickening of emulsion on standing. Try to either cut down or eliminate just to confirm the fact.
-
Agreed with MakingSkincare, calculate the SAP values of Shea Butter and Coconut Oil, saponify and there you are with the soap. Disperse in water and you have so and so % aqueous solution of Shea butter and coconut soap (maybe with little added preservative). And that my friend has been used as one of the ingredients here I suppose.
-
Single pot creations won’t warrant for a standard procedure of heating the oil phase and water phase separately, can be heated all together but of course depending upon the formula. Also it would help if a chronology could be set for adding the ingredients in the pot depending on the physical state of the ingredient.
-
@Gustavo bang on money re the lazy phase.
-
@ssdc Take a drop of finished emulsion between 2 glass slides, rub the slides a little and see under a source of light. Would give you a rough idea of aeration in your emulsion.
-
I am not sure where I read it but most probably it was used by Mr. Tony Lennick of Siltech in one of his articles. Think he was suggesting the most stable CMC where chances of any mess up are pretty much low or neglible. Or this is what I made of it
