    The level of perfume is too high and can be the reason.

    why using two Preservative with total level 2% that seems soo fake.

    Then stearic acid with Triethanolamine give Triethanolamine stearate which is high hlb emulsifier.

    May you need cationic surfactant and yes you can use only CAPB and glycoside.

    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.

    What about reducing some Actives surfactants to have lower viscosity?

    Just try low dilution and watch the result.

    Using amount of low hlb emulsifier may solve the problem.

    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.

    @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)

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

    @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.

    @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.

    That will be not the level of active surfactants but the level of surfactants and even it is the level of active it is higher then the required.
