Consumers in general are, at best, vaguely aware. Pressure comes from retailers and their “priority lists” influenced by industry parasites loke EWG and EDF (e.g. https://www.newbeauty.com/how-sephora-is-doubling-down-on-their-chemical-policy/). And there are is occasional moronic legislaion (e.g. https://ecology.wa.gov/waste-toxics/reducing-toxic-chemicals/washingtons-toxics-in-products-laws/toxic-free-cosmetics-act).
Alternatives - “natural” (that very rarely are), clean beauty, preservative-free etc. preservation is sold on ignorance and hype as are the broader product claims of biodegrable, natural, green, environmentally friendly, sustainable, etc. The number of such product claims is typically inversely proportional to micro and chemical safety. But that IS the basis of our cosmetic business, ignorance and hype - add hope and self delusion.

How Sephora Is Doubling Down on Their Chemical Policy
The beauty retailer just released a report that details their partnership with the Environmental Defense Fund.

Katie - check it for microbial contamination.
-
What “tristate” is that?
-
If phenoxy - be sure to add ethyl hexyl glycerine
-
Generally, yes.
-
isothiazolinone (MCIT) is a better primary preservative for this product - and you should have two, not just one.
-
What is the preservative?
-
Makes sense!!
-
water?
-
Wash idiots set lead at ngt 1 ppm. Lipstick is typically biggest concern - FDA recommended a limit of 10 ppm - their testing (2010) found quite 40% of lipsticks > 1ppm.
-
Legislation by morons.
You’re referring to Lead/Lead compounds?
-
Pretty crazy preservation - esp. @ pH 7-8. Benzyl alcohol, a little cap glycol with 3 organic acid/salts, none near pH optimum, and a degradable chelator. Benzoate might be served by surfactants and benzyl alcohol/benzoate can synergize.
evchem is spot on.
-
Phased out.
I know this is not your immediate question, but be aware - the preservative is not legal in the US for this kind of product.
-
Come on Mike -it doesn’t take a scientist to make and sell soap.
-
Should not use isothiazolinone (here Kathon CG) in a leave-on product.
Also difficult to get effective dispersion of small quantities (e.g. Kathon) added to finished product.
-
Ingredient statement must be provided at point of purchase - with responsibility being on the head of the “guy” named on the package. You’re seeing attemtp at cya from retail folks for their inventory control practices.
-
Not aware cosmetic companies comment that they may not be in compliance with FDA regulations. Can you name the ones you saw?
-
“Kathon CG” and similar isothiazolinones include both CMIT/MIT (`3:1), the latter (MIT) is an impurity from synthesis and present at an ineffective level. Only used in rinse off products, this is clearly the go to primary preservative in shampoos and conditioners.
-
Meant as a rule of thumb. I’d reco additional, more water soluble preservative.
btw - i meant in ref to isothiazolinone, CMIt (chloromethyl-) not MIT. If it makes a difference to your policy position.
-
Safety is your responsibility - and there is no “non-” re the toxicology endpoints identified above.
Do you think a preservative may be needed?
What definition of “natural” are you using? Decyl glucoside may be naturally derived but is still a product of chemical synthesis.
-
Not legal due to regulatory restrictions - nothing to do with safety.

Would help preservation but don’t know abut impact on buildup.
-
Forget the Geogard. If all you can get is phenoxy, add ethyl hexyl glycerine.
-
Agree, the ascorbic acid reaction to benzene is not a concern in this context. Might have problems with some clays, but I’d not worry much.
