afaik, concentration of CMIT/MIT in product (%) is 0.0015 is safe

Risk Assessment of 5-Chloro-2-Methylisothiazol-3(2H)-One/2-Methylisothiazol-3(2H)-One (CMIT/MIT) Used as a Preservative in Cosmetics - PMC (nih.gov)

and DMDMH maybe useful for fungicidal efficacy?

thank all of you for responding. Good day for all, cheer

and Merry Christmas!

[oldman20]

anyone have ẽxperience with it? mr @PhilGeis

[oldman20]

isn’t hydroperoxit not long-stable in solution? how can keep oxygen atom stable?

[oldman20]

did you try another thickeners in that formula?

[oldman20]

yes, i have experience this case

[oldman20]

hi, i have similiar you case, but on others product

[oldman20]

thank, but the question in this case returned from #1 post: how NaOH can neutralize fats if neutralized with acid? or NaOH will reaction both fats and acid same time?

[oldman20]

and just curious: how they decided push that product into markets when it doesnt pass time in incubator?

[oldman20]

many thank for information. do u have any link, edition relates to that? i cant find anything exclude Word of mouth

[oldman20]

i think it relates to surface tension

[oldman20]

i think in this case oven like incubator funtion, if i true, 45 Celsius is popular

[oldman20]

i read from TDS’s Aecosolv: It solubilizes fragrance and a wide range of lipophilic ingredients to create clear formulations.

So exactly Aecosolv is the solvent? What case is need it? when fragrance is too high?

[oldman20]

Why Mg2+ can do that than Na+?

[oldman20]

yes, i have same the way you are

[oldman20]

thank you, i will notice that

could u take short look this? do u know about incubator?

If you’ve ever wondered why there aren’t more cosmetic chemists who have their own brand, this is why. It’s hard to maintain the perspective needed to be a successful marketer when the science of reality is staring you in the face.

Interested with this. I think correctly that honestly!

[oldman20]

thank, i got it. so if that happend (decrease viscosity) not appear immediately (in my case example), it will compatible?

[oldman20]

it’s mean need use both carbomer with salt (like NaCl) together to ensure viscosity?

[oldman20]

thank your useful answer!

[oldman20]

thank for information. I will take look it. also i faced case when use formula without LABSA, seem NaCl can put more than when not contained LABSA. thank for repeat me again

[oldman20]

thank so much about it!

[oldman20]

thank, do u know about combined CMIT/ MIT with DMDMH preservative?

[oldman20]

thank, so why not use citric acid or weakess acid for that? i think HCl is to strong

[oldman20]

oh, thank for advice for all!
