Denatured is generally used to avoid the abuse of the material, there is no other reason I suppose for this. Absolute alcohol is generally used for pharma and to some extent for OTC products.
In the above case it is there for one more very important reason and that is to aid in the solubilization of Salicylic acid which has a very low aqueous solubility. -
If you are importing the base then I suppose you have to specify the supplier if you are going to use it for top coat or base cost or a pigmented/pearlized shade. Think they do it at their end to make it formula specific, this is what I observed when I was doing these polishes and enamels.
Secondly if you read the literature of this Texaphor 963 it won’t give you any thixotropy (on its own) and consequently you would face synerisis. Has to be used with other binders to invoke thixotropy.
I remember our bases used to have some bentones for suspending the pigments and pearl particles.
Eventually everything is going to settle down by the force of gravity, depends how much you can really prolong it and call it the stability of the product. -
Quick reply
to emphasize the absence of preservative if it has been omitted because I suppose (and please mentors correct me if I am wrong) <30% ethanol eliminates the need of preservative, secondly to show that it is 40% ethanol and has to be used accordingly on the skin type. Last but not the least, maybe to emphasize that since it >60% it cannot be used as a sanitizer.

From your previous posts I am guessing you need to wash the tanks which you have used for dish-washing liquids and similar kind of products. I have seen that lower alcohols like ethanol act as very good de-foamers, could possibly use IPA as well here.

All said and done I was thinking that the juice I drink has a long list of chemicals, the sliced bread that I eat in my breakfast has a long list as well, the salt I consume, the wafers, the biscuits, the dairy products, and what not.
Oops I completely forgot the gluten in my topical application product!!!!!

This should give you some idea about these claims
And there many more in favor and against such claims. It is just one of them.

Benzyl Salicylate is essentially a component of the fragrance in the formula, and not a preservative. The anti dandruff agents seem to double up as preservatives and maybe one or two of the extracts too may help in preservation here.

I doubt if it is a complete ingredient list, with a resin I am sure a plasticizer would be needed too as acetone is definitely going to render the film brittle. With pigments there has to be a suspending agent as well e.g. some kind of bentone or some other agent, how else you are going to avoid synerisis in the polish. Pigments and pearls are definitely going to be pulled down by gravity and as per my understanding those 3 cant really do all the jobs at the same time.
That is purely my understanding about polishes and I hope someone senior can chip in with a better understanding if mine is off the mark. -
Try to optimize at lab level and then scale up. How about starting with a kg of sample and study its salt curve, this would give you an idea of how much you would need for 100 L.

@Bob interesting indeed, though I too have done a little fooling around. But mine was a replacement of one perfume with another in my w/o emulsions, as the shipment of our perfumes got delayed. Thankfully no one could notice the change of fragrance.

I suppose the fishes
will always be there with DMAE, but as you said there might be some essential oils which can mask this smell to only SOME extent. -
Continuing with Ruben’s observation I would like to add that many esters also have typical fruity smells.
-
@Belassi Oh don’t be surprised, I know few reputed suppliers who are willing to supply any namesake that a customer is looking for. Times have changed indeed.

The boon of ‘X’ FREE or ‘Y’ FREE or ‘Z’ FREE has become the bane for the industry and has provided ample opportunities for any tom, dick and harry to spread fear mongering at the drop of a hat.

I ONLY interpreted that sentence, don’t take it as my opinion or suggestion.
-
Meaning it can support the presence of significant amounts of oil in the formula. Think that should give the pointer.
Cheers

@Bimsmide ozgirl is bang on money here, other day only I had a little chat with my supplier and jokingly we had this suggestion that we should add LABSA to our shampoo formula as many customers feel that foaming is not up to the mark. On a more serious note I suppose you could play with LABSA for more foaming and adjust the rest of the things for ASM.
-
I really appreciate the feedback though there are few souls here who would just take off after asking for pointers and suggestions. Bless them.
Cheers -
Yes it is indeed!!!!
-
But isn’t it really contradictory that you are trying to wash off and at the same time trying to put some oil back (re-fatting for the sake of it). And if there is surfactant and if there is oil, why would the surfactant allow that oil to stay on the skin???? Does it mean the surfactant is under-performing???????
Excuse me but empty mind and devil’s abode (3 days break and so these weird things going on in my mind) -
I did that with a little amount of DPG, worked well.

International Lacquers/Fiabila/Durlin and so on

Then Bobz has given you the best option (especially the hydrogenated PIB aka Indopol H100) especially for products like lip glosses, have used it myself with castor oil and it comes out a winner, provided the formula is well balanced.
-
@hishine1 Guess some of the polybutenes might match the flow and tack (to some extent) of castor oil but if it is about some OCM then you have lots of options of vegetable oils although I am not sure about the tack.
Or the next best thing is 12-Hydroxystearic Acid but alas it is a solid while castor oil (upto 90%) is having same carbon chain but that one double bond turns it into 12-Hydroxyoleic Acid and hence a liquid.
