  • What should the ASM range be for a handwash?

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


    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


    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.

            ALS, sci, scg and an amphoteric

        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! 🙂
