I’d put it on ingredient label. Why do you think it’s on so many shampoo labels?
e.g. it’s on the Pantene shampoo ingredient label with the explanation on P&G’s website ” An AHA that comes from citrus fruits. It is usually used as a helper ingredient to adjust the pH of the formula.’

need formula parameters

Through what period does this develop?
-
If you’ve completed the stability series - hopefully though 3 years- not beyond change control.

Not buying into the premise of hand made better - think that is very subjective and parochial consideration. The true “better” has to be in the mind of consumers.
However, understand there is a profound difference between what is effectively a hand made product and a product from mass, automated production.
The latter is going to be consistent, responsive to/constrained by extensive safety, quality and cost considerations and expanded in appeal by professional marketing.

SOP or batch sheet - in a language operators understand. You do not want them making product from memory, even short term memory, so it has to be immediately available to the operator and simple enough to be followed with ease.

I don’t know either. I do know CMIT sensitizes at a much lower exposure level than MIT -CMIT is MIT with one added Chlorine. DCMIT has two added Chlorines. Still the DCMIT is a very small %.
-
What do you know of DCMIT safety?
I don’t know stability - what surfactant?. Challenge test so final product application should give you some assurance and that must be repeated tough the period of premix use.
-
I would not.
What is DCMIT? What else is in it? Some salt for stability?
At 14%, the volume added is so small, you’ll have trouble getting it sell mixed. For a premix, you should prob ensure it’s stable.
-
I would not. Too much unknown.
Industrial preservatives are classified as pesticides in some countries (e.g. US) and some countries specifically ban the use of pesticides in cosmetics (e.g. Canada).
For some suppliers - these are the same a stuff - just labeled differently. For others, the stuff intended for industrial market is less controlled, more impurities, byproducts..

phenoxy is ok - soluble enough water , well > use levels. Cerave hyaluronic acid serum uses it as PE 9010. Add something for fungi.
Can’t address eczema concerns.

(esp. natural) positioned toothpaste is often poorly preserved - relying on flavor components, Aw and fairly protective packaging. Manufacturing needs to have real tight controls.

The fewer ingredients is a marketing concept. To the question “… is there any drawbacks to making very simple products?” Nothing per se - if it is safe (microbiologically and chemically) safe.
As expressed as the clean concept, it embraces the (usually fake) natural and often, (equally fake)”preservative-free” marketing extension. It is both dishonest and risky.
-
Excellent points. Products themselves may not have been tested on animals but as you said it’s hard to think safety of each ingredient was established without some animal testing - or perhaps safety hasn’t been established.
If you want to chase this claim, look for products from folks who have the cover of cruelty-free certifications. Saves time and you’ll have deniability

phenoxy is soluble in water to ~2%
-
Pretty weak system that would require protective packaging and high level of manufacturing hygiene attention. Has a real Gram neg weakness Gluconolactone breaks down to gluconic acid - think I’d use EDTA.

I understand it works for you now. I offer the following from experience.
Allow me to clarify - this is your company culture - batch instructions, SOP’s, etc. are library documents. Operators own the batch and will resist the loss of authority if required to follow batch sheets/SOP’s for more complex products. They’ll train the next operator who will never bother with instructions. Efficiency, consistency and regulators will eventually require the sheet is in the operators hand as immediate direction to make.
Continue to grow, you may/prob will need to eliminate the cowboy operator. If one of the big guys buys in - it is a certainty. This will impact corp. moral as these are loyal and senior folks.
-
Prob more in the document but responding to “Stir until combined” - in what equipment/at what speed/setting/how does an operator know what combined means? Undefined terms in SOP’s will be defined by the operator/modified by the new operator/modified by the next operator. Over simplified batch directions/SOP’s become irrelevant. No one will reads ’em - any of them.
-
Take a look at ISO 29621

At 0.2 Aw you should not bother to challenge test. Stndard tube is protective packaging.

0.5% (5000 ppm) phenoxy has been my ceiling. What is pH?
GLD? As in GLDA? Why not edta?
-
No - haven’t spoken to Dave recently think he but hasn’t been involved for a some years
-
Yes - suppose you could if use was immediate. I would not
