Help! Toner is sticky!

edited October 2017 in Formulating
Here's a rundown:
A.Ethanol-35
Salicylic Acid-1
Betaine-1
Fragrance-0.5

B.Water-qs
Glycolic Acid-1
Sodium Lactate-1
Alpha-Arbutin-0.2
Multifruits BSC-0.5
Quinoa Extract-0.5

C. PEG-40 HCO-1

The problem with my toner is that it is sticky. I lessen the % of Sodium lactate from 2.5 to 1. Still sticky. Any thoughts?

  • It's probably the ethanol. I did not find a way around this. However, the effect should go away in a few minutes.
    Design of anti-aging creams, gels, and serums; shampoos; and therapeutic cosmetics. In-house label and box design capability.
  • Betaine tends to be quite sticky.  If your Multifruits BSC are in a glycerine base, that could be another contributing factor.

  • Silicone polyol DC  193 (1-2%) 
  • Update: Removed betaine. Still sticky. 
  • my prime suspect is PEG-40 HCO; try using a different solubiliser, e.g. polysorbate 20

  • Update: Removed Betaine and Multifruits BSC. Still sticky. 

    @Bill_Toge I only have here PEG-7 Glyceryl Cocoate, Polyglyceryl-3 Caprylate/Caprate/Succinate and Propylene Glycol, PEG-40 HCO and Polysorbate 60. 


    One of my benchmarks has PEG-40 HCO but it doesnt feel sticky. 
  • @Bill_Toge As far as i know, polysorbates are sticky. I'm just using a solubilizer to clear my mixture cause it gets cloudy once I mixed phase B to A. 
  • Try replacing some of the etoh with PG
  • agree with @Bill_Toge. @Lainee try lowering PEG 40 to 0.50% since your alcohol is already at 35% the risk of having a cloudy solution is low already. You wouldn't need too much PEG-40 since it seems to me you don't have to solubilize any oil at all.
  • Add bit butylene glycol or propylene glycol. You have also some water soluble silicones thar remive sticky after feel. You can also add bit of hyaluronic acid.
  • I guess also with only 1% salicylic you can reduce ethanol. 35 is too much. I guess with 15% it will be enough. If you add butylene glycol it will also helps to solubilize your salicylic acid.
