Amount of surfactants in liquid hand soap.

My formulation for the liquid hand soap is as follows.

1. SLES (70%) - 10 %
2. CAPB (30%) - 5 %
3. CDEA - 2% 
4. Glycerine - 1%
5. Salt - 2%
6. Dye - q.s
7. Fragrance - q.s
8. Citric acid - q.s
9. Water - to 100 %

Note: All the percentages are weight percentages.

I am encountering an issue with this soap, it leaves a sticky residue on the hands and the foam does not vanish even after a rigorous rinse. After going through multiple sources I doubt that the formulation has insufficient surfactants. There must be a minimum and maximum percentages for each of the above surfactants. Please provide any resource for determining the proper percentages of surfactants which would result in a commercially acceptable product.

Best regards

    Deduct CDEA and reduce Glycerine .
