    What do you want the ingredients to do in the formula?

    You can put 0% - 5% of glycerin. It just gets washed away anyway so it won’t do much in your formula.

    For PQ7, most people use it at a level from 0.1 - 1%.  Usually it is at 0.5%

    There is nothing such as “perfect percentage” in a shampoo. It depends on many factors. Price, raw material availability, consumer expectations, marketing, other ingredients, stability etc etc. What @Perry mentioned is a starting point.

    There isn’t any ingredient you can add to a shampoo that will moisturize skin for a long time. And as far as conditioning goes, PQ7 will provide some conditioning. It won’t be as good as something like Dimethicone but that won’t be ask good as having the consumer use a post shampoo conditioner that has cationic surfactants in it.  Your question is just not specific enough because terms like “hair so silky and fine” has no scientific definition. I don’t know if your consumer uses the product with PQ7 in it that they will think the hair is silky and fine feeling.

    Is there a product on the market that you want to emulate? It would help to start there.

    I don’t know if your DEA % is appropriate. That is a level that has been used so it’s not unreasonable. It is a secondary detergent so it shouldn’t weigh down the hair. But this is something you have to test with your consumers because you are asking a question of perception. I have no idea what your consumers will think.

    With respect, how do you expect any of us to give you any meaningful advice if you post such vaguely-worded questions and don’t even provide an accurate list of ingredients?

    You can’t formulate your product for a single customer. To solve that problem tell your customer not to use your product.

    For more detailed answers you’ll need to be more specific and give more information as @Belassi suggests.

    Please list the ingredients rather than trade names. The formula doesn’t add up to 100% and without knowing what the batch size is, what percent is “150gm”? Why make things difficult for people when you want help?

    No No … it is not difficult 150 gram of EDTA  this is for 100 kg shampoo product

    0.150 EDTA 
    1% polyqueternium 7

    That’s a standard sulphate based shampoo like 98% of the ones on the market except that you’re using quite a lot of cocamide DEA which has a pH of 8-10 and therefore I suspect the pH is alkaline and causing problems.

    We generally adjust shampoos and Skincare products to 4.5 to 4.7 or so. Conditioners we do at about 5.5 to 6 or so. There are numerous reasons to support these pH values. However, pragmatically (in uncompromised adult skin) I really doubt that the slight pH differences would be all that significant.

    There is a substantial subset of consumers who find SLES irritating. If you want to be able to offer them a product, I suggest formulating a shampoo with less irritating surfactants. An ALS/ALES/CAPB combination would be less irritating. Better than that, you will have to use a sulphate-free formulation.

    You are using cocamide DEA, not DEA. Do you understand what the CDEA is for? Do you understand what the salt curve is and how to do tests to reveal it? I hate to say this but it appears to me as if you are trying to formulate products without any experience. If that’s the case I recommend you find someone who knows what they’re doing. Seriously.
