    Hi I am trying to make a natural hand soap. A really basic formula: coco betaine, carpal/caprylyl glucoside, propanediol, fragrance, preservative , citric acid. It leaves my hands too dry after a few wash, what I can add to avoid this problem?
    thanks in advance

    You’ll probably want a refatting agent or conditioning agent.
    The two go-to’s are glyceryl oleate or polyquaternium-7. I’m sure someone else might give some suggestions.
    What % actives do you have and what’s your resulting pH?

    Hi Thank you, the pH is around 5 and total active is 10%. I also added some Benzalkonium chloride to make it antibacterial.

    10% is on the milder side of normal for hand washes. pH looks fine to me too. The Benzalkonium chloride shouldn’t have much of an impact on skin dryness if it’s used in small percentages. 
    Re-looking over your formulation, I’ve seen mention of glucosides being reasonably cleansing of lipids/fats/oils, so to add refatting agents. I’d say that’s a good place to start and see how you get on with that.
