2 in 1 shampoo
Hi, I have made a 2 in 1 shampoo and used in the formula polyquaternium-10 (Ucare extreme from Dow). At the level recommended for this application (0.3 %) it performs well but makes my shampoo feels a bit slimy. Is there any thing I can do to avoid this problem?
Thank you. -

You’ll need to provide the rest of the ingredients to get helpful suggestions

Hi Perry, thank you for your reply. I have used in the formula the following ingredients: Sodium Cocoamphoacetate, Sodium Methyl Cocoyl Taurate, Cocoamydopropyl betaine, herbal extracts, lauryl/Myristyl Polyricinoleate, glycerin, essential oil, citric acid, vitamin E, Caprylhydroxamic acid, glyceryl caprylate. At first, when I dissolve polyquaternium 10 in water it seems fine but then the problem is when I mix it to the other phase. I am wondering if it is not compatible with some of the ingredients.

Usually a little slimy-ness in a conditioning shampoo with PQ10 is a good thing: means you are getting favorable cationic sensorial deposit on dilution. Having said that, you may be facing an order of addition problem or that polyricinoleate builder is the culprit. Always disperse & completely hydrate PQ-10 into the water first, then add the amphoterics immediately afterwards - and you have two there. Anionic surfactant next then any builders. This way you optimize coaceravation of the PQ-10. As for that polyricinoleate builder, switch it out for another builder such as an amide and observe any difference in “slime.”

Thank you for your advice
. I did other tests and one of the problems was the order of the ingredients, another problem was the preservative that I have replaced. Now the solution is perfect until the end when I add citric acid to adjust the pH and the viscosity increased considerably.
