Thank you so much for your advice, I will try all that and tell you what happened.

See you later

@Chemist77

The turbidity or the product becomes opaque when I withdraw it from the plastic container in which it deposits and expose it to the open air for a long time (24 hours), the product is still translucent in the plastic container

Is it because of silicon oil and pvp this phenomenon?

[Rebelgreaser66]

I was thinking, and maybe what happened was a phenomenon of oxidation in the product and this is why its coloration became opaque?

[Rebelgreaser66]

@DRBOB@VERDIENT.BIZ 
 Knockout experiment? sure!

If anyone knows that could be causing the crystallization in the formulation, I would be very grateful if I discussed it and help me to get a solution

I clarify again, this only happens if I leave something of the sample to the interperie for approximately 24 hours

[Rebelgreaser66]

@Belassi @DRBOB@VERDIENT.BIZ
Here is the new formulation

Ingredient                         %

Water                                47,1

Propylene Glycol                2,0

Benzil Alcohol                    2,0

Polysorbate 20                   1,9

PEG 7 Glyceryl Cocoate      6,0

Vegetable Glycerin             4,0

PEG 40 castor oil                0,7

Polysorbate 80                   1,0

Fragance                            0,5

Pvp k30                              3,0

Ceteareth 25                      30,0

Silicone oil                         1,0

Any suggestions to avoid crystallization?

I clarify that if the product remains in the open container does not happen, only happened when you take a sample there and leave it outdoors

[Rebelgreaser66]

@MarkBroussard i will try that combination , Thanks 

But is the percentage of benzyl alcohol in the formulation okay? There is no risk?

@MarkBroussard @belassi @chemist77 @em88

And talking about the preservation and stability of the product, this was what was obtained:

I take a sample of the container, exposed it to the air, to the interperie and now it looks like this:

Is this normal? Or is there any stability problem?

[Rebelgreaser66]

Hey @Chemist77 @MarkBroussard Thanks for the advice, these were very useful.

I have achieved the desired consistency in the final product. Apparently, the problem was the heating temperature, raise the temperature to about 85 ° C, and I have separated the mixture into two phases, which after being brought to that temperature I mixed them and worked well

But, I have one last question:

In my formulation, I have reduced the water level slightly, increased the C-25 and maintained the percentage of benzyl alcohol in the mixture (2%). Understanding that benzyl alcohol works as an antimicrobial agent and can also cause skin irritation, Don’t you think the percentage is high? Could it involve any risk to the skin?

I thought of reducing this percentage to 1% (0.5% of Benzyl Alcohol and 0.5% of another preservative, Maybe, Phenoxyethanol) But I don’t know and I would like to know your opinions about it

Thanks so much!

@MarkBroussard @Chemist77
 i trying to replicate a formula i have fully developed from a formulary. The goal is producing something like this:
https://www.maggardrazors.com/wp-content/uploads/2017/01/Hey-Joe-Strong-genuine-hair-pomade-100ml-2.jpg

But the problem is that the ceteareth isn’t dissolved completely in water and if i mix with a mechanical mixer, a lot of foam is formed but the ceteareth is totally dissolved 

So i think that maybe if i use an anti-foam agent could work but I don’t know what agent could use in this case so that it does not involve any risk in its application

[Rebelgreaser66]

@MarkBroussard  @Chemist77  Here is the formulation

Ingredient                         %

Water                                59,1

Propylene Glycol                2,7

Benzil Alcohol                    0,5

Polysorbate 20                   2,0

PEG 7 Glyceryl Cocoate      1,7

Vegetable Glycerin             1,4

PEG 40 castor oil                0,8

Polysorbate 80                   1,3

Fragance                            1

Pvp k30                              3,5

Ceteareth 25                      25,0

Silicone oil                         1,0

Today i increased the heating temperature to 75°C in a Home water bath ( I don’t have a lab water bath) and the ceteareth remains undissolved completely

I tried mix  with a mechanical mixer, the ceteareth dissolves completely but too much foam is formed, and the silicone oil does not function as an antifoam agent

The ceteareth stayed like:

[Rebelgreaser66]

Yes, the c-25 is 21% in the mix 
Thanks @MarkBroussard , I will try it 

The goal is producing something like this:

[Rebelgreaser66]

I study chemistry and  i like the topic of cosmetical chemistry  but this in my country is a pharmaceutical chemistry student business 

For this reason I ask the above questions and not make a wrong formulation

“Have you also considered PEG Bundy?”  Hey dude, maybe your mom could works better.

How rude!

[Rebelgreaser66]

@Microformulation Could you suggest some books for that? 

[Rebelgreaser66]

thanks so much @johnb  
and the last one please

could be replace the peg-7-glyceryl cocoate for the PEG-100 Stearate?
it’d have same effect or similar over the formulation?

[Rebelgreaser66]

Sorry for my poor english i’m from argentina

I meant, What other component could be influence the ‘hold’ of the pomade? 

[Rebelgreaser66]

Johnb, yes, PEG-7 is peg-7-glyceryl cocoate and PEG-40 is PEG-40 hydrogenated castor oil

The origin of the formulation is an attempt at replication of “suavecito” hair pomade. The Formulation is not mine, i saw it of  a project of a college partner 

So, Again:
 
Which substances could replace PEG-7 and benzyl alcohol in the formulation?

What other component could be influence the effect over hair hardness? (soft pomade, medium pomade, hard pomade)

Thanks 

[Rebelgreaser66]

The remaining percentage is the amounts of Benzyl Alcohol and PEG 7 ( 2,5% and 4,9%)

About beeswax , in the formulation isn’t included  but i’ll wanna know its influence if i’ll would decide using it in the formulation 

Chemist77 is clear 

Thanks so much

[Rebelgreaser66]

What determines the hardness in the formulation of the pomade? Maybe the amounts of beeswax?

[Rebelgreaser66]

Water                                    57%

Propylene glicol                     3%
