Thank you so much sir🙏

I’ll try to do as you suggest🙏

[Rufiano]

I’ve done accelerated stability test (at 60 celcius), and my cream experienced a phase change after 3 weeks…

[Rufiano]

@Perry44 halo thank you for the respon.

I used basic ingredints:

- span 80 4,5%

- tween 80 0,5%

- glyceryl stearate 4%

- Cithrol GMS 40 1%

- cetyl alcohol 2%

and citric acid for adjuster.

[Rufiano]

If w/o emulsifier and o/w emulsifier are used together, viscocity will increase and make the cream is getting harden, isn’t it? and it will make cream easy to wash (not water resistant). I’ve tried to add salt in water phase but still separate, anyone can please help? Anyway thank you for your answer

[Rufiano]

Update! I’ve try to add antioxidant (BHT) to my formula & it’s a bit work. The yellow of my CAP is decrease but still has different colors if compared to the original CAP.

Does my % of BHT is not maximal or any suggestions maybe?

Thanks, Sir.

(I didnt use Tinogard bcs i didnt have)

It’s very limited literature about Belsil DADM 3050 & It’s my first project making leave in conditioner.

It’s just about 2% of Belsil DADM 3050.

I need enlightenment whether Belsil DADM 3050 needs a solubilizer or surfactant because the solution I make is like milk which leaves residue on the walls of the beaker.

& FYI Belsil DADM 3050 is comprises:

<b style=”font-family: inherit; font-size: inherit; color: var(-bb-body-text-color);”>Amodimethicone (and) Dimethicone (and) Cocos Nucifera (Coconut) Oil (and) Trideceth-3 (and) Trideceth-10 (and) PEG-100 Stearate

Thank You

[Rufiano]

I’ve tried to substitute Belsil DADM with more water dispersible silicone (PEG 12 Dimethicon 2%), but it doesnt give a conditioning effect on hair, the fact is my hair becomes tangled & dry.

Can you please give me a suggestion, should I increase its concentration (PEG 12 Dimethicon) or add other conditioning ingredients?

Actually, i wanna use Belsil DADM 3050 BUT I havent got the solution about the instability before (Gel appear on my solutions)

Thank you

[Rufiano]

I’ve take out belsil DADM 3050, so i didn’t have silicone on my formula.

But, the solution remains yellowish, and the cap remains yellowish too. Is it oxidized?

[Rufiano]

Wow thank you sir, it helps me a lot…

Yes my problem is caused by the silicone & i’ll try more trials

[Rufiano]

Oke i will try.

Thank you ketchito🙏

Have a nice day.

[Rufiano]

Oke, thank you philgeis🙏

Have a nice day.

[Rufiano]

Aah… i think so, some water has evaporated.

Do you think it would be better if I increase the concentration of the water or humectants, ya?

Thank you ketchito for your kind to response

[Rufiano]

This is my company’s sop related temperature of accelerated stability test, and we always use those temperatures for other dosage forms.

Can you give me one of the most important pieces of advice I can do?

Should I lower the temperature or maybe increase the concentration of other components?

Thank you

[Rufiano]

Halo philgeis thank you for your kind to response.

Leaving aside the temperature, do you know what factors caused the change in my cream rinse?

Does its humectant or occlusive rate affect?

-Thank you

[Rufiano]

Thanks a lot graillotion for your help!

So, because the amount of my water phase is bigger than oil phase (70% water phase),

is it still accurate if I take a ph measurement at the end of the product?

[Rufiano]

Yes… i used some w/o emulsifiers but the total of oil phase is less than water phase.

Is this correct and can still be said w/o cream?

Thank you…

[Rufiano]

I’m a little confused, does the amount of water phase must always be less than the oil phase if you want to make W/O cream??

BUT I see in some sources either google or not there are many formulas w / o but have a greater number of water phases.

Thank you

[Rufiano]

You said the oil is continuous phase and tiny water droplets are suspended in it and only tiny small droplets hit the probe of pH meter BUT the amount of my water phase is more than oil phase, it’s about 60% of water phase. Do I still have to adjust the pH in water phase??

THANK YOU…

[Rufiano]

I’ve tried to adjust the pH in the water phase but the result was same, the final pH 7 commas

[Rufiano]

Yes, i am adding the water phase to oil phase slowly (drops by drops using pipet) and i used mgs04 as electrolyte stabilizer in water phase

[Rufiano]

It’s about my R&D SOP in my company & i always use that temperature for acccelerated test, for other product too

But geepee, can you tell me whats wrong on my formula? am i using too much w/o emulgator?

Previous, i once used mgso4 for stabilizer at water phase but the result was same, stable on 3 weeks only.

[Rufiano]

My formula is about 75% water phase & 25% oil phase.

And i add the water phase to oil phase ad 70 C…

[Rufiano]

I used Emplilan EGMS with the INCI is Glycol cetearath.

Here’s:

Cetyl OH 2%

Gms 4%

Glycol cete 1%

Span 80 2%

Plurol 3%

Do i use too much emulgator??

[Rufiano]

Sorry i didnt get it, what do you mean excessive? the temperature, isn’t it?

[Rufiano]

Here’s the formula:

Aquadest

Glycerin

Chlorpenesin

Cetyl Alc

Glyceryl monostearate

Glycol cetearath

Span 80

Plurol oleique

IPM

Mineral Oil

ZnO

Can you help me what is wrong with my formula?

Thanks a lot
