What type of antiperspirant are you making? Solid/ stick, roll on / emulsion, paste, spray? The manufacturing process will depend on what you are making.We make a roll on antiperspirant (emulsion type) with Aluminium Zirconium Tetrachlorohydrex gly and add slowly it to the cool down phase with moderate speed stirring at less than 40C.I know that the Aluminium Zirconium Tetrachlorohydrex gly is not suitable for spray type products.We just use standard safety precautions (e.g. gloves and eye protection) when handling. -
Try using Lamesoft PO65 from BASF. It is glyceryl oleate blended with coco glucoside. It is cold processable.

You could also look at Cosmedia Ultragel 300 (Polyquaternium 37) as this was recommended to me for thickening cationic systems. It was too costly for my project but might work for you.

I remember reading somewhere that the issue is that young children already have potentially high salicylate exposure due to teething gels and thus adding an extra exposure may make it unsafe.The European Cosmetics regulations are based on science so I personally wouldn’t risk it when you have an alternative that is safe and works.Salicylic Acid is also restricted under ASEAN Cosmetic regulations and is not to be used in products for children under 3 (except shampoo).
-
In Europe Salicylic acid is prohibited for children under 3 years of age.

Wheat proteins are great for the skin! -
I would double check with your supplier.Are they a reseller or the manufacturer. The information above comes directly from the manufacturer.You need a mildly alkaline pH to keep the Potassium Stearate (the emulsifying part of glyceryl stearate SE) in the soap form.In any case you could try it at pH 7 and see if that fixes the problem.
-
Your pH is too low for the Glyceryl Stearate SE emulsifier. Your pH needs to be between 6.8 to 8.2.

Here is a good starting point for formulating Liquid Dish Wash products.
-
Is this formula for hand washing dishes in a sink or is it meant to be used in a dishwashing machine (dishwasher)?In any case it is not suitable for either application.
-
How much glycerin did you use? Glycerin can feel sticky at high amounts.Share your formula with percentages for more help.

You can purchase denatured alcohol from New Directions Australia.

@geekchic We use a liquid (paste) version (Hi Foam 750) from ChemRez (Phillipines). We prefer this as it does not need heating.I’m not sure where you are located but Colonial Chemical in the USA sells a flake version of Cocamide MEA which I think needs to be warmed to allow for fast dissolution.Just to note that Cocamide DEA is usually sold as an ~80% active liquid with the a portion of the remaining liquid being free DEA (usually around 5 to 10% free DEA).
-
I haven’t worked with Blue Tansy but it is possible that it is something in your emulsion turning yellow (oxidising). Have you tried a sample without the Blue Tansy added? What else is in your emulsion?Adding an antioxidant is a great starting point to try and fix the issue.
-
Personally I would try changing to cocamide MEA (or using additional CAPB) as it is the Diethanolamine (DEA) content that is the issue with carcinogenicity.We swapped from Cocamide DEA to a liquid form of Cocamide MEA a few years ago without any real issues. We only had to do a few minor pH adjustments from memory.
-
It is 30% active.

I would love to be a minimalist but unfortunately the marketing team requires the fairy dust ingredients.Where possible I try to use fewer ingredients in the base formulas.
-
Trulux in Australia sells Montanov 82. They ship internationally but not sure if the price is workable for you.
-
Why would you replace low cost ingredients (Xanthan,HEC) that are known to stabilise the emulsion with a very high cost ingredient like HA? Or are you looking for a different sensorial profile?If you want to add HA for label appeal just add a small amount post emulsification as Mark Broussard suggested.

Happy Birthday Perry!

@esthetician922 you will need to find an oil soluble calendula extract or change to a different oil soluble extract (or leave it out all together).
-
What is the base of the Calendula extract? Is it an oil soluble extract? Or has it been extracted into Glycerin, Water or Ethanol?
-
Yes but it might be easier for your customers to understand if you claim Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) free.

How much hair spray are they using in Los Angeles? Not sure how accurate the data is but it must also be noted that this study was published in 2018 so would not include the increased use of hand sanitisers in the last 2 years.

Great video. I loved her stitching the retinol back together at the very end
