I was introduced to this type of stirrer ages ago and it became my standard general use device for efficient mixing.

A couple of points about using Lubragel products.
1. Be careful about the base medium. There are a number of different grades and several are unsuitable for contact with rubber (condoms).2. I have not found Lubragels to be as “slippery” as Polyox formulations.

Triethyl citrate (TEC) is generally considered to be safe on the skin but, there is no guarantee that a sensitive skin like yours will be OK. Test it first.
TEC, as well as being a good solvent, is also a recognised treatment for acne vulgaris so, possibly this action may be useful in treating seb. derm.
Be very careful in applying essential oils to your skin. The alacrity in which some people suggest treating the skin with pretty much neat essential oil (whichever one it may be) leaves me very concerned.

The only commercial huanine pearl essence I know/knew is Mearlmaid from Mearl Corp. This company appears to have ceased trading and the plant closed in 2007 see http://quoddytides.com/mearl1-12-07.html

You might want to consider using a polyethylene oxide in place of/in addition to HEC.
The lubricating properties imparted by HEC (and other water soluble cellulosics) are not particularly efficient and do not offer much in a viscoelastic effect (pituity/slipperiness)Polyethylene oxide (traded under Polyox, Dow), depending on grade, excels in pituitousness and approaches the ideal required in a personal (sexual) lubricant.
Take a look at http://www.dow.com/scripts/litorder.asp?filepath=/pdfs/noreg/326-00001.pdf&pdf=true if that doesn’t work try http://www.dow.com/dowwolff/en/industrial_solutions/resources/literature/index.htm (the top link in there).
Note that Polyox polyethylene oxide is NOT a version of polyethylene glycol.

Climbazole is not a common cosmetic ingredient and its properties will be little known to most cosmetic chemists.
I do work in the area of topical pharmaceuticals but climbazole doesn’t come within my remit - this is why I suggested Tom.
One thing that comes to mind - and this is only a notion - triethyl citrate has some interesting solvent properties and might be worth a try. Other than that, have you Gooooooogled climbazole solubility?

You may want to contact Tom Busby at https://rosaceagroup.org/The_Rosacea_Forum/forum.php
He seems to specialise in this.

Perform all processes under a blanket of inert gas when working with oxidation sensitive materials.

The original silicate antiwrinkle composition was from the late, great dermatologist, Albert Kligman.
His efforts can be perused in European Patent 0244859:
“An aqueous composition comprising human serum albumin and sodium silicate
is useful for cosmetic purposes for application to the human facial
skin to effect smoothing of the skin and temporary removal of fine
wrinkles. The liquid composition containing sodium silicate
and human serum albumin is applied as a coating or film on the skin and
permitted to dry. Upon drying, the dried composition lifts the skin up
and the fine wrinkles there beneath are smoothed out and removed.”It should be borne in mind that sodium silicate is a fair general term for a range of compounds of varying ratios of Na2O:SiO2 - some of them more or less neutral in reaction. It is unfortunate that the Chinese, in their efforts to copy Kligman’s formulae, chose a highly alkaline version of sodium silicate, thus ruining any potential the product might have.

The hand sanitizer market place is stuffed to overflowing with companies trying to gain a market share. Few succeed.
Unless you have some revolutionary idea which can be implemented with no additional cost involved, I suggest you look at other ideas. -
The manufacturersof fabric conditioners have the market pretty much tied up for themselves and it is almost impossible for a newbie to produce an economically viable product.
Facric softeners usually comprise a 3 - 5% dispersion of a di(long-chain)alkyl dimethyl ammonium chloride in water. The “long chain alkyl” is C16 - C18 and frequently hydrogenated tallow. The most common raw material is Arquad 2HT 75 (Akzo-Nobel).

The answer to your question about quantity of BAC is clearly stated on the LOI for the product exemplified.
I make no comment on the efficacy of the product as I have not tried to use it or been able to test its antimicrobial properties. This you should do comprehensively before marketing.
-
As it’s a spray, non-volatile residues are not so much of a problem.
I remember an A/F spray patent from SCJ that claimed to reduce the number of pathogens in air and which relied on triethylene glycol as a carrier and catcher of airborne particles (including bacteria) trapped by the droplets in the spray.
Actually what the TEG was doing was acting as a solvent for the fragrance in an aqueous base. The other properties were most likely marketing puff.

It is very difficult to formulate a product which has reasonably effective H/S cleaning properties whilst retaining antimicrobial effects from a cationic (whether that cationic is CETAC, BAC or any other).
As I wrote, above, most countries have strict regulations regarding microbicides. I doubt very much that hard surface cleaners with cationics would fit in with this.
-
What form does this A/F take? Spray? Static diffuser? Reed? Othe reservoir with diffuser device?
The reason I ask is that any form other than an active dispersion system, such as a spray, will have large residue (24% or so in your formulation example). The user will see this as an indicator that the product is still active (even though it has lost its smell) and then fail to purchase further product or, worse, complain the air freshener doesn’t work.
This brings me back to my suggestion of a glycol ether as solvent. The product would then be completely or almost completely volatile.

Be very careful that you get the correct grade for your needs. Not all guanine has a pearlescent effect.
Note that almost all pearlescent guanine is extracted from fish scales - which may not suit animal-free products. -
David, I think there is some crosstalk here. The product is an airfreshener, not a personal deo product.
Even so, a TTO fragranced air freshener is not something I would want in my house
-
Hard (multi) surface cleaners containing cationics must be very carefully formulated in order not to inactivate their biological activity.
It would be far preferable to have a separate antimicrobial product to use after any cleaning has taken place.
I don’t know where this product is intended for but most countries have very specific requirements and restrictions for products claiming antimicrobial/antiseptic/germicidal properties.

You might want to consider a glycol ether in addition to a detergent based solubiliser.

Sodium sulfite usually acts as a reducing bleach, not a colour stabiliser.
UV fading is a very common problem with the soluble (oil/water) colorants approved for use in cosmetic products.
The most reliable answer is to pack in plastic containers which have a UV absorber incorporated into the polymer. Even so, this is not 100% reliable and most colorants will fade in time.

All of this assumes that the mineral oil is of a suitable refined grade.
Engine oil is usually mineral oil but I would be very cautious about using that in a cosmetic product.I recall many years back a lab junior took it upon herself to formulate a product including castor oil as a component. Poor girl could not make a stable emulsion so she asked my advice. It turned out that she had assumed that castor oil was another name for Castrol oil (https://en.wikipedia.org/wiki/Castrol) and had used the latter in her formulation.

” I am looking for resources/ references for a Brand Development Company or individuals who can do the job for low cost.”
Pay peanuts, get monkeys always springs to mind when I see anything like that.

Don’t know whether this link will work but it is about pigments sourced from autumn leaves. Not quite the subject under discussion but interesting.
Link works for me!

- and the remaining 2% is? (your declared formula totals 98%)

A material with some similar properties to resveratrol is maritime pine bark extract (Pycnogenol).
This is soluble in water and may suit your purpose.
Note that Pycnogenol is a brand name. Unbranded MPBE is a lot lower cost.
