You have to ask for the PDS of your glitters and inform your NP base supplier, in that case only you can avoid such situation. In case of OPI I am guessing it is the oxidation of Al in presence of solvents which caused it.

[Chemist77]

Glitters IIRC are polyethylene terephthalates and one has to choose the base accordingly, just like selecting the plastic container for different products. You have to specify your requirement to the supplier and there are some good ones like IL, Fiabila, Durlin and so forth.
Don’t forget to mention ‘shake well before use’.
Hope this helps.

Thanks @MarkBroussard.

@MarkBroussard Do they work individually or inclusion of citric acid provides a better environment for Dissolvine functioning? I have Dissolvine NA and NA2, do you think the acid will help here as well??? Last but not the least, can citric acid be used across the board with dissolvine or it will depend on formula type e.g. ok for a shampoo or dishwash but not for a cream or lotion or any similar emulsion??

[Chemist77]

Try Empipearls from Huntsman, they too come in different combinations.

[Chemist77]

Is it because of the structure like branched and linear or some other reason????

[Chemist77]

Try to use mixture of lauric, myristic, palmitic and stearic acid, set the pH above 7 and wait sometime for the effect to set in. Or use a high percentage of stearic acid, say 15% and very minimal oil, neutralize to pH 8 and you would get the effect in sometime.

[Chemist77]

I would keep that one from Zink.

[Chemist77]

Well you surely can add that percentage by changing to hot process shampoo, its more appealing and robust for such ingredients as your dimethicone.
Good luck.

[Chemist77]

On contrary I have this perception that pearlized variants are more viscous although there is no hard nd fast rules, it depends on how u formulate. Btw that 2% Amodimethicone is way too much for a shampoo, did u check the PDS???:

[Chemist77]

depends on perfume type nd other formulation parameters, ask ur supplier for substantive perfume for such rinse off product nd make sure ur temperature is conducive to the fragrance stability.

[Chemist77]

Try once without Amodimethicone, I am guessing that as the culprit.

[Chemist77]

I absolutely agree with @MarkBroussard on being in college and know nothing, in fact now only after the experience I understood what it was that I studied in my BS.

[Chemist77]

Did u try to look for Memmert????

[Chemist77]

Yeah since Jojoba oil is actually a wax and surely very natural and appealing. Only addition from me would be the usage of pigment muds rather than using dry pigments, dispersion defines the appearance.

[Chemist77]

The only thing is that PEA smells of roses.

[Chemist77]

Guess this is about hair straightener where formaldehyde is used extensively and at times it is coined differently to avoid the term formaldehyde e.g. methylene glycol, methanal and so forth. There is much more to it but I guess this is enough where @Bobzchemist has already given a wonderful explanation. IIRC only in some nail products it can go up to 5%. 

[Chemist77]

Be careful, aeration is a big problem with Aqua SF1.

[Chemist77]

Just an addition, they were doing four cycle challenge test and depending on the customer request they are willing to extend this period further. 

[Chemist77]

@MarkBroussard I was recently in Dow Microbial Lab and witnessed something about paints and their preservation over a period of years for microbial and algae growth. They used a  patch of paint in the middle of the dish and sprayed with microbes to be tested and separately with algae to check the efficacy of the preservative. 

I don’t know how relevant it is for you but I guess this is how you would go about solids as well and as you mentioned by using a paste of it. But next time I am there I am gonna brig up this point just to make sure. 

[Chemist77]

@Bobzchemist Brilliant dissection!!!!!!!

[Chemist77]

Misleading LOI, incomplete.

@Perry Since the cat is out of the bag can we see this now

Perry,

[Chemist77]

Here you go-

Remove stearic acid, incorporate 4% Cetostearyl Alcohol, if needed more viscous add 1% Cetyl Alcohol. Skip the carbomer too, not going to help here. 

Benzalkonium Chloride is a quat but it is generally used as an anti-microbial, the remaining 2 can be tried and yes that diester is a fabric softener material. But I have seen few companies pushing it in conditioners and balsams too, of course they call it PC grade.

@Perry Clear enough to understand.
