What should the ASM range be for a handwash?

Posted by Heath0o7 on April 22, 2024 at 12:22 am

Hi,

I’d like to formulate a mild handwash, but I need some help, please. What should the active surfactant matter range be for a handwash in general? Here’s my formula:

The sample is a 100g Batch size:

Distilled water

1.3% Guar Hydroxypropyltrimonium Chloride

0.5% LG+

0.3% GLDA

Disodium laureth sulphosuccinate

Coco-glucoside

Caprylyl/capryl glucoside

Phenoxy + EHG

0.5% Fragrance oil

Lactic Acid (pH between 5 to 6)

~10-15% active surfactant

I would say 10 - 15% ASM is way too high. Hands are small area to clean. 10 - 15% ASM would be used in something like shampoo.

For face and hand products I would aim around 5% ASM. If you use good foaming surfactant it will be just fine and it will not over clean (and dry) the skin.

  Thank you for the clarification @Paprik
  
  Do you think the combination of Disodium laureth sulphosuccinate (3% active) and caprylyl/capryl glucoside (2% active) would produce a good foam? I’ve decided to only use those two surfactants.

    No it will not and it will be difficult to thicken too.

      I see, what would you recommend to use @Abdullah I have the following surfactants: decyl, coco, capryl glucoside, CAPB, Disodium cocoamphoacetate, Sodium lauroamphoacetate, SCI, SCG, SLGC, Amine oxide, ALS and AOS.

    Sulfosuccinates are relatively good at foaming. Just give it a try. It might be just right for hands. You do not need a really excessive amount of foam.
    
    They are hard to thicken, so definitely need a thickener.

      Just wanted to give you guys an update, I ended up using Disodium laureth sulphosuccinate, Sodium lauroamphoacetate and Caprylyl/capryl glucoside and the formula was actually thick before I added a thickener. I decided to use 0.9% Guar Hydroxypropyltrimonium Chloride as my thickener and the handwash turned out nice. It’s somewhat foamy, but I don’t mind that as I know I don’t need foam to get rid of dirt. Thanks everyone for your help! ????
