Have you requested a cooling agent to be included or suggested to them that they do this? There are lots of potential materials available.
-
The cool effect may be provided by one of the ingredients present under the disguise of flavor.
There are a number of materials that will achieve this but, unless you are a reasonably sized manufacturer, these may not be available to you.
It is a specialised area and if you want to pursue this, I suggest that you contact a flavor house/manufacturer

I’ve added a few more acronyms to your list, Perry but I notice one entry in your list which condlicts with my understanding.
From what I recall SARA stands for Superfund Amendments and Reauthorization Act and this is backed up by: https://en.wikipedia.org/wiki/Superfund

Collagen is not soluble in water and because of this, it is not drinkable.
Collagen drinks invariably contain hydrolysed collagen - that is collagen which has been treated with acid or alkali or proteolytic enzymes to break down the high molecular weight insoluble protein into smaller molecules which are soluble in water. This progresses: collagen > gelatin > peptides > amino acids.
Don’t be too influenced by marketing hype. People are making a lot of money by renaming quite common biological materials as something special.
I noticed that one of the “collagens” has a revealing description as to its constitution see http://skinade.com/the-science#the-collagen-in-skinade
Hydrolysed fish skin (more or less what makes up Skinade) used to act as glue in bookbinding.
You should also be aware that INCI applies to cosmetics products only.

I believe it is the lactate ion that is more important here, not the pH value.
-
Noobs should not be contemplating making products of this nature.

Zink, apologies about me thinking you are in Hungary. The mistake arose from me looking at your “about” page where the first entry is from a Hungarian contract manufacturer. My speed reading led to the error!

Coconut oil has been used by a large proportion of the world’s population for many centuries for many purposes - not least as a cosmetic product.
There are few, if any negatives about its long term use unless, of course, there is some rare hypersensitivity to it.
-
Collagen per se has little function in a cosmetic product as it is effectively insoluble in any of the materials used in cosmetic products. It is thus not used.
Hyrolysed collagen is used as it is soluble in water but the hydrolysis process destroy any identity it may have had in regard to it being type 1, 2, 3, or any other classification.
The INCI name for the material is hydrolysed collagen. Hydrolysed collagen is also termed gelatin (or gelatine) but this naming is more common in the food industry.

For numerous reasons outlined above, a lone synthetic detergent would not be very successful as a shaving cream.

There are number of members here that may be able to help you

As with Miracare SLB, Iselux SLV is merely a blend of quite common surfactants being sold at an inflated price.
LOI:
Water (and) Sodium Lauroyl Methyl Isethionate (and) Sodium Lauroamphoacetate (and) Cocamide MIPA

Doesn’t this:
I found an other cream in the local market. They use urea 15%, lactic
acid (not specified the % and salicylic acid as preservative (most
likely 0.5%).take us back to my first reply in this thread:
A lactate buffer can help stabilise urea in solution

You really ought to provide more details of your requirements.
-
Hedging around a definitive answer then - guarding his own rearend, you might say.
As I mentioned previously, as there is more than one inspector involved, there is always the danger that the more strict one may re-appear and tell you that what you are doing is all wrong.
-
All finished drug products I have seen have an Expiry Date.
This is in the UK and Europe. As you are in Hungary, Zink, I assume this applies to you. The FDA is powerless over here despite what they might want you to believe.
Check the European Medicines Agency web site for a definitive answer http://www.ema.europa.eu/ema/index.jsp?curl=pages/regulation/general/general_content_001772.jsp&mid=WC0b01ac0580b18a39

Neutralised salicylic acid does not act as a keratolytic so there is little point in using TEA (or any other base) to do this.
TEA salicylate (trolamine salicylate) is used as a topical analgesic.

The world seems to be full of different brands of hand sanitiser.
Are you certain you want to enter this very overcrowded market?

To be certain, contact the perfume house/supplier.

I still keep to my original comments here.
You have two officials with differing views and, unless the more strict one has transferred or met his demise, then I would suggest that there is a reasonable chance of another visit from him. This being so, if you have relaxed your diligence in the so far that you have, not only gone against his directions but have introduced a system ( the Schülke & Mayr method) which he may not agree with.
I realise this will be almost impossible to do but it would be strongly in your interest to get an “approved” statement of what the requirements are - and to get and retain hard copies of all that is exchanged between you.
-
The reason I asked about other ingredients was ascertain if there was a water content. As there seems not to be then the likelihood of micro-organism growth in the product is effectively nil. This does not mean that an antimicrobial preservative should not be included as there will be incidental contact with oral fluids (saliva) during use. Phenoxyethanol should be suitable or, if a stronger rose note is acceptable, phenethyl alcohol is good antimicrobial.
Another point: Don’t become too dependent on your use of organic ingredients. The relevance of the term “organic” becomes lost when your product includes ingredients direct from the chemical factory e.g dimethicone, isododecane, cetyl alcohol.
-
Why not non-organic castor oil? There is nothing quite like castor oil.
Coconut oil/lecithin would not be effective substitutesRegarding preservatives, what else is in the formulation? Vitamin E may act as an antioxidant but would have little or no effect as an antimicrobial preservative.
-
@Donmattus I know you from another forum.
As this vitamin E is for your own purposes, may I suggest that you buy softgel capsules of the material. You can open them with a pin and squeeze out the contents to use as you wish - direct application of dilution of small quantities in your moisturiser blend. Doing this will avoid any problems with oxidation on storage of free oil and is a convenient and low cost way of buying the material.

As far as I was aware, this mixture was originally marketed as a convenient part pre-formulated hair conditioner requiring only appropriate dilution and a polymer thickener/stabiliser (hydroxyethylcellulose or similar) to give a finished product. It resembles the ingedient mix of a hair conditioner that was very popular some years ago which, by its market share at the time, amply showed that more complex formulations of hair conditioner were unnecessary.
As so often happens, formulators have played around with this blended material trying to make to perform in products it was never intended for. It is for a hair condtioner. Don’t try to make it do other tasks.
In regard to your latest post here:
I was told that one sufactant can’t make a stable emulsion, there must
be combination of low, high HLB surfactants and emulsion stablizers. In
the case of BTMS, I can see behentrimonium by itself as the solublizer
but not an emulsifier.None of that is true and a great overgeneralisation.

i use blood red and bit of caramel colur to make dark red it becomes totally white like water
Surprised that caramel fades to white.
