    You might also try using about 0.2% Guar Hydroxypropyl Trimonium Chloride.  It is a foam stabilizer

    What have the judges defined as natural?  Isn’t everything “natural” since there is no such thing as “supernatural”?

    @Belassi - It has some oils in it.  sunflower, almond, grapeseed.

    But we used to sell a product called “VO5 Hot Oil Treatment” which had no oil in it. Oil is a marketing term.

    Also, what do you consider natural?  

    Decyl Glucoside does not actually occur in nature.

    I’m all for improved systems but what problems is your software solving?

    Can you list some benefits that your software application does better than an Excel spreadsheet?

    The reason I continue to use and recommend Excel spreadsheet is because it is…

    • easy to use
    • other people are familiar with it

    Plus, I’ve seen no demonstrable benefit to using something else.  But I’m willing to be convinced. How would my formulating life be different if I didn’t use Excel?

    Of course using potassium sorbate can lead to a yellowing of your product over time. http://www.sciencedirect.com/science/article/pii/030881468890074X

    October 17, 2016 at 8:45 pm in reply to: Best moisturizer for a rinse-off product.

    There is a secondary reason you can include glycerin in a rinse off product. It can help prevent the product from drying out. Typically, a shaving gel is dispensed from a pump or aerosol and some of the product can get left behind in the opening. Without a humectant, that bit of extra product can dry out and block the opening.  If you include glycerin in your formula you reduce the chances of that happening.  It doesn’t moisturize the skin, it moisturizes the formula.

    I agree with @Chemist79 about using glycerin. It is water soluble and will simply wash away during use. It will have no noticeable impact in regards to moisturizing for a rinse off product. This is true of any water soluble ingredient that doesn’t have some mechanism to stay behind.

    Cationic polymers are a good choice.

    For viscosity you can use xanthan gum or methycellulose.  For humectancy/moisturizing you can use polyquaternium 10

    Instead of Sodium Benzoate you could also use DMDM Hydantoin.

    1% Phenoxyethanol for a product that isn’t rinsed might cause irritation.

    If you’ve overshot the salt curve then @Belassi suggestion to add some soap that has no added salt is your best bet.

    This is why companies use synthetic chemicals to make shampoos. They are just more safe.

    If you care about the safety of your products more than your marketing positioning, you’ll reduce the level of ingredients like linseed mucilage, honey and lemon juice to levels below 1%.

    If the product is effective at all (moderately or more) it is an illegal drug. 

    If you are trying to build a legitimate business following the lead of people who are breaking the law is a terrible business plan.

    5 gallons is too much? That will be a challenge.

    But you should check with the Ontario SCC and the Quebec SCC.

    You would have to be able to show that when the ingredient is added to the conditioner it has any effect on luster and hair strength. If you can’t show with or without it has an effect, then it doesn’t much matter if it is heat sensitive or not.

    Sounds like a great situation in which you should do a knockout experiment.

    Yes, it works primarily on Anionic systems. Non-ionics can be used as secondary surfactants to help with thickening.

    I agree with @Bobzchemist.  If you want to sell your product idea, turn it into a successful product line. It will be much easier to sell then.  No cosmetic company wants to buy an idea.
