Zinc Pyrithione-Based Antidandruff Shampoo | Hallstar BPC

This antidandruff shampoo formulation uses particulate zinc pyrithione as its active ingredient, and HallStar® SAB-2N Flake to maintain the active ingredient in dispersed form. HallStar® SAB-2N Flake also contributes opacity as well as desirable rheological properties to the finished product. By … Continue reading

With CAPB and glycoside as I guess you can reach a quite good product,sure for shampoo you need more ingredients for having a basic free sulfate shampoo so you have to work more for getting better results.

[Fekher]

What about reducing some Actives surfactants to have lower viscosity?

Just try low dilution and watch the result.

[Fekher]

The level of alcohol is good however the level of perfume and mpg can be reduced.

[Fekher]

Using amount of low hlb emulsifier may solve the problem.

[Fekher]

Soo far to be acceptable formulation, increase the level of xanthan gum, the level of surfactants and decrease or eliminate oil phase they are just waste of money and efficiency of product.

@evchem2 today I found out the secret of the reason of why using the keratin sometimes it gives crystal clear solution and sometimes it gives opaque solution. Actually for the second time opacity problem appears when I use the bottom of bottle so I supposed that the top of the bottle is Cyclopentasiloxane (according to the color, viscosity) and in the bottom it is the keratin (yellow colour different with the top colour wich is transparent) wich cause the opacity problem. So thanks for your suggestions and i’am sure now that  your second suggestion is the right one.

@bahey first I go with @DAS why using ipa I guess ethanol is much better, then I will not go with @ketchito for his choice because according to my experience in such level 10% of fragrance you did not need some ingredient that bloom you fragrance so for you case I will just using peg 40 it will almost solve your problem. 

[Fekher]

@chemicalmatt @ketchito actually the inci as I said:(Cyclopentasiloxane - Keratin Amino Acids) so it is not water based keratin then I worked 15 kg with level up to 2% of this keratin getting crystal clear product so if it is the cause of turbidity why reaching the 2% for first Batch I did not have any issue. 
  Update to all, today I verified the lot of other silicones and unfortunately they have the same lot then I made a batch of 500 grams getting not clear product moving to 100 grams batch I got crystal clear product. I’am thinking according to what I saw that it is related to report (exchange surface /volume)  (Note : I mixed the 100 grams and 500 grams in same reactor) 

[Fekher]

@Pharma the manufacturer is Active concepts. 

[Fekher]

@Paprik how stearic acid is anionic?  Actually it is fatty acid with carboxylic acid function without negative charge. 

[Fekher]

@Perry so according to you finding the adequate energy of mixing will solve the problem?  Actually tried mixing with different energy and that did not improve at all the transparency 

@ketchito actually it was manuel mixing with very low speed so I supposed temperature is the room temperature.
my ingredients are : brb1834, brb dm 350,brb cm 50,AC KERAIN AMINO ACIDS SIL (inci:Cyclopentasiloxane - Keratin Amino Acids), perfume

@SunilHiwarkat1965 thanks for your precious share just why using all that ingredients to solve the problem, c12_15 alone was not enough or for more efficiency?

@evchem2
 1)I eliminated the mixing reason because for the first purchase when I made 100 grams then 1 kg of product then I moved to 20 kg there was no issue in manuel mixing   so if we supposed that the transparency problem was from different mix energy why I did not face that issue in the first purchase? 
2)I had the same reflection about raw material variation and I think that is the real reason I verified the keratin and it is the same lot however I did not verify other ingredients and thanks for awesome share about pump and syringe
3)formula as I said contains: brb1834, brb dm 350,brb cm 50,AC KERAIN AMINO ACIDS SIL (inci:Cyclopentasiloxane - Keratin Amino Acids),perfume. 

[Fekher]

@Abdullah room temperature in same time by manuel mixing with same tool.
@Pharma about acid amino keratin it is another strange phenomenon for the first purchase I worked the formulation with more then 1% level without any issues however in the second purchase even with 0.2% serum loose transparency same thing about the level of perfume I needed to decrease the first level for maintaining the transparency. 

[Fekher]

@Pharma it is not optical ‘illusion actually I put the product in same packaging to jude the transparency and is not the same for sure. C12_15 was suggested by @chemicalmatt for solving transperncy problem when adding perfume in silicone serum, so I made a try for my product and it did lovely job for small batch. 

[Fekher]

@Perry I don’t think soo,  the mixing was manuel by the same tool. 

[Fekher]

@Riyas it is logic to have low foam with such formulation just increase the level of SLES and it will be fine. 

[Fekher]

@fotis83 actually there are a lot of qualities of SLES then for sure you can find safe one. 

[Fekher]

You are welcome.

[Fekher]

You are welcome and waiting for good news.

[Fekher]

Which is the level of active surfactants in such product? it seems more then needed

[Fekher]

Nice new information thanks a lot.

[Fekher]

Thanks for the add.

[Fekher]

Thanks a lot for your precious reply, so when xanthan gum can have stability problem versus cationic or it is a fake information? I because I readed it in many resources supposed professional.

[Fekher]

The problem did not solved and I guess it will not for water based wax.

[Fekher]

Actually yes i’am interested with update, and I did not see any mention about this problem’s product and I find it really bad product because there is no waring about seperation.
