Hi Ketchito,

Thanks for the encouragement. Let me try again. I purchase Dimethicone (properties below) and add water to the liquid silicone in a 4:1 (formula: water) concentrate mix and 32:1 (formula:water) RTU mix.

The Dimethicone properties are as follows:

- nonionic,
- visc-10M base oil,
- 50% silicone content,
- visconsity of contained oil @ 25C 10,000 (cstks)
- dilutent water

I am looking for a preservative that would allow me to use this chemical on young children as a spray in detangler. Because many of my users are allergy sensitive and look for hypoallergenic solutions, I am sensitive to finding a mild preservative system that would not affect any sensitivities of the users.

Hopefully this clears things up?

Thanks,

jackie

Hello

I figured it out… it is nonionic, visc-10M.

This product has been on the market 50 years and never had a problem. Now we have a problem and never having been in this position before i do not have the skills to problem solve. I only know how to follow the formula.

I do realize this is a chemist forum and i am not a chemist. I apologize i do not have the lingo and am not trained. Trust me, i have called and searched everywhere and every formulary i’ve been able to connect with has minimums to even open a discussion. I have spent over 8 weeks on this and clearly i am not effective at connecting with the right people. I was drawn to this site because in the process of attempting to educate myself, I found the thread discussing leucidal a month back which prompted me to reach out and ask for help. I had presumed that if people don’t like leucidal, there must be other “obvious” (albeit, not for me) and more appropriate alternatives for dimethicone diluted with water.

Once i have recommendations, it is much easier for me to do compatibility research against the other ingredients. I was simply asking for some initial go to suggestions. I didn’t provide a formula because my interest is not in getting into the weeds but rather, again, a specific thought on what ingredient(s) I might consider to inhibit mold growth in dimethicone.

i apologize for wasting folks time; I will look for a more appropriate venue to ask my questions.

Regards,

Jackie

Emulsified. not 2 step.

How do i go about locating a challenge lab in the midwest? The lab that identified the fulsarium does not do challenge tests.

So if it’s impossible to eliminate, how do i identify a preservative system that will inhibit mold development?

Hello,

I have run labs on the formulation and it has tested negative. The facility is also negative. I am presuming the exposure is occurring either through storage or bottle printer. This has never happened before in 50 years.

Water is mixed with the dimethicone but my understanding is that it is not oil based. We use a water based fragrance (vs oil).
