    In next few years, these EOs might become the fuel of choice for NASA missions to Mars. You just never know the benefits until you try it ???

    I have had few PETs with Phenoxyethanol as standalone preservative in my wet wipes solution and it came out good. I am sure @1%  you should be fine, never used Mikrokill so no idea on that.

    @Gene the soap acts as a defoamer in such laundry detergents.

    A regular formulation with the choicest selection of words for marketing cock and bull story. Check Innospec products and you will find everything there.

    Try Phenoxyethanol only, salts and electrolytes will hurt the anionic thickener via charge cancellation. Euxyl PE, not sure why it is behaving that way. Have you tried solubilizer just in case.

    I meant Ceteareth-20 can be brought in for the 25 mole ethoxyate. Have no experience of doing such a product with Jojoba ethoxylates.

    You better get rid of those foaming liquid surfactants or reduce them drastically. Make a batch with just the fatty alcohol ethoxylate, glycerin, propylene glycol, PVP & preservative. Once you get the base right, think of adding the fragrance and other additives. I have used 25-30% ceteareth-20 and it has been wonderful without issues. Ceteareth-25 generates more aeration and foaming, I couldn’t handle it with my lab equipment. Gave up on it. Ceteareth-20 is my star now for this pomade formulation.

    @Belassi gotta have that Polytrap 6500, you have mentioned it so often that I am compelled to check its efficacy and performance. What would be the best vehicle in your opinion, emulsion, anhydrous balm or something else???

    It is generally 96% active grade, I have used SLES and it is almost 100% success rate. You need to optimize the formulation accordingly, search this forum and you will find quite a few threads on this topic with complete information.

    @AFRIDI85 Where are you located, @ozgirl good suggestion on Kathon CG but might get costly for home care. Instead glutaraldehyde from Dow again is the go to preservative. 
    You need to jack up SLES to at least 6-10% there to have salt thickening. Get rid of CDEA, maintain CAPB if cost isn’t a big deal. Then there are 1000s of additives to improve the performance. Get the basic formula right, can guide you further after that.

    @Belassi 
    Fourth that is one of the most vague formulations I have ever come across. It’s like an amalgamation of powder detergent and manual dish wash. 
    @Lil how did you arrive at this formula and what is your benchmark here.

    Disperse in water and neutralise with citric acid under pH 4, it will clear up and you are good to go ahead with other additions in the formulation. This is cationic guar and no need of pre-dispersion.

    That wax is dispersible/miscible with the oil components, solubility is not an option in my guess. Best you can do is filter the oil and get rid of the insolubles.

  • @Bill_Toge I remember having this issue some 13 years back and we had the same combination or DEA with Germall 115. Sadly after that DEA has become a universal villain with people taking it for granted that DEA in formulation means nitrosamines. I am yet to find a conclusive study where it is clearly mentioned that DEA itself alone is responsible for such occurrence.

    Yeah in case of ethnic hair you need that extra push, guess 0.5% is a decent start.
    If you need detailed literature, just pm your mail id and I would send you the one from Dow & Innospec.

    My 2-in-1 shampoo has 0.3% and it makes the customer pretty happy. You could go a bit higher, go through the literature though and see what maximum high you can hit without overkill.

    They are cationic including the quaternized guar, since they are conditioners and reduce friction it might have worked in your favour. In that case give it a try then, otherwise over conditioning may cause limping and flat hair if you think of normal hair.

    I second @Perry, one of the best neutralising agents I have come across. The clarity is unmatchable and there is no yellowing of the product on standing. Have seen transparent gels going yellowish with sodium hydroxide and TEA over a period of time.

    Polyquat 10 is more of conditioning polymer, styling wouldn’t be a strong feature of this product. It is hygroscopic too, so there goes your curl retention out for a toss.

    Either the pH or one of the components of essential oils is still my guess. I have seen both in my lab with a bleach liquid and a dipentene stored in HDPE containers, separately.

    In that case you definitely need a good amount, have you thought of AMP-95. A very good one that though bit on expensive side.
