    In my opinion adding more is pointless, rheology and transparency becomes a problem and you are duplicating the cost. If you want more fragrance in you shampoo ask you supplier to make a specific version for your product that fits your needs.

    You should mix it with a few drops of dimethicone or any foam killer. Otherwise it will take time to clean the foam afterwards.

    @David08848 im saying that big manufacturers sell to smaller ones, and yes, the small ones might just sell you a dilluted scent.

    “Fragrance companies don’t engage that that type of activity”

    Beg to differ. That’s exactly how it works. It’s quite common the use of bases to formulate fragrances, and not only for trade secrets.

    And that is not a bad thing, the quality of the scent depends on the formulation and the quality of the raws, not the concentration.

    Why anhydrous?. The problem using ethanol is the irritation, you will end up sneezing every time you breath it. Won’t stain unless you use too much oils, or if you spray repeatedly the fabric.

    I have never done this before, but my guess is that hydrosol is useless, mainly because it has to be used in high doses. 

    I doubt alcohol would be useful for other thing than dispersing the oil on the salt. Just consider this: you have 1% oil in 1kg of salt. Lets say you use 100gr, that’s 1gr in at least 100lt that will fill up a tub. Considering you are dispersing the salt and moving constantly it would take a long time for the oil to come together. 

    Anhydrous may be a third option. Would be easier to add an emulsifier.

    Yes there are, hydrosols. A byproduct of the manufacture of absolutes I think.

    I was thinking about, lets say a thorough inspection. You can rub the certificate over the inspectors face, regardless the kind of surfactants you use.

    SLES 25% is not good enough?. Anionic, cheap, neutral and easy to find. That and hot water. By the way NP has great detergency, but is nonionic.

    It does lots of foam and it is agressive. Given the nature of you product I suggest you aim for detergents used in reactors for milk and cheese production. I think SC Johnson makes them, and since they are for food grade machinery the components and quantities are in the label.

    Sometimes is marketing and a carefully chosen set of words. Like claiming it doesn’t have added preservatives, doesn’t mean the raws don’t have *wink wink*

    Won’t it need a considerable amount of antioxidants?. By logic, even a powdered product will oxidize very fast, and considering it will be on the hair for several minutes you will need a strong combo. And still, what shelf life might have?.

    They are plant based, keep in mind that plant based doesn’t mean natural, and natural doesn’t mean safe.

    Contamination and shelf life comes to mind. And the fact that nobody wants beer smelling hair. Why don’t you try a wine version instead?. I think it would have more acceptance commercially, there are many grapeseed oils available and you can cover up the smell easily. And if you want to add a solid for the looks just chop some cork :P

    You should contact the factory, maybe a bad esterification ruined all the derivatives.  It’s all Hallstar?. You could contact R&D, with the batch number they must have a counter sample to at least, tell you why is happening and how to fix it.

    Reverse acid esterification perhaps?. Are they all from the same brand?.

    LMAO it’s even misspelled. I came across that brand a few months ago doing research about animal shampoos, it was actually presented like a leading case on the niche. The curious thing is that they exported it to Europe and Middle East. With that label, really??.

    I know, nothing has been proven, and I’m sure most of the cases are consequence of misuse. But we have seen monster companies pushing the limits many times. They fund and make the reviews, and they have a powerful lobby all over the world. Even if it’s currently the best product I don’t understand why it hasn’t been tested more thoroughly by states. 

    My point is that we consume every day products that are within the safe limits, things that we don’t event know about, and the summatory of everything has severe consecuences on human health. So an article like this one seems more like the easy way out instead of analyzing health problems as a whole.

    Tea is commonly used to adjust pH on acne treatments. The result would be an analgesic.

    November 8, 2017 at 11:35 pm in reply to: Where to buy Euxyl PE 9010

    My advice is to call the local office of Schulke and ask for the list of resellers of PE 9010 they have in the area. Then call one by one and ask for prices, sizes and shipping. It’s best if you call a direct distributor to assure the quality of the product. So far I never had a no for an answer.

    I’d be more worried about what Monsanto puts on the crops, but then again very few have the balls to fight the lobby. We are eating genetically modified seeds sprayed with glyphosate that surprisingly after 40 years of research nobody knows for sure if it’s really bad or not that bad. The farmers get cancer and their kids are born with deformities, but it must be something else.

    The UN suggests not to use antibiotics for healthy livestock, and we eat more hormones in a chicken than a transgender on estrogen therapy.

    But what the hell, it must be that damn poisonous shampoo…

    You will get the same result, which is an unstable emulsion.
