Dry Flaky Skin after using Body Wash
Hi everyone! Just want to ask your opinion on what I could be doing wrong. I made a body wash and it causes my skin to dry, flake and peel. It seems to be very harsh. What could be causing this? Here’s the formula
Sodium Coco Sulfate - 8%
CAPB - 15%
Coco Glucoside - 10%
Aloe vera extract - 5%
Decyl Glucoside - 7%
Glycerine - 3%
CMEA liquid - 2%
Panthenol - 2%
Polyquat 7 -2%
Fragrance - 2%
Tetrasodium EDTA 10% solution - 1%
EHGP (PHENOXYETHANOL & ETHYLHEXYLGLYCERIN) - 1%
Citric acid q.s.
Distilled water - 42%

In my opinion it is quite possible you are getting an allergic reaction, probably to the glucosides.
-
I would add a refatting agent (lipid layer enhancer) like Lamesoft PO 65. Also perhaps look at boosting your humectant properties with something such as Methyl Gluceth-20. No offense to anyone, but without more pronounced erythema, urticaria or other dermatological signs of an immunomodulated reaction, I would probably discount an allergic reaction at this time.

What’s the final pH of your product?
-
@chemnc Another great question, especially with APG’s.
-
@Belassi the original formulation had 17% decyl glucoside and was okay. Could someone have a reaction to Coco glucoside but not to Decyl Glucoside?
-
@Microformulation isn’t glycerine and CMEA not enough as humectant and refatter
-
@chemnc pH is 5.4 after adding citric acid 50% solution
-
CMEA (Cocamide MEA) is not a significant lipid layer and the glycerin is not enough in my experience.
isn’t glycerine and CMEA not enough as humectant and refatter
I think your initial problem says no it isn’t.Loo into the Lamesoft PO 65 or at least read the documents.

The reason for my original comment is quite simple: I see no other substances that are likely to cause the kind of problem you mentioned. -
Thanks everyone for your inputs. Couldn’t get Lamesoft PO 65 and Methyl Gluceth-20 here in our country.
I made different batches of this formula with varying surfactants. For some reason, those without CMEA didn’t cause irritation which was weird.
Made a small batch of body wash without CMEA and I didn’t get itchy skin. I got CMEA for for refatting and it causes my skin to itch, get red and flake.
What will I do now with all the CMEA I have?!
-
Others may not agree but in my opinion the cause of your problem is the glucosides. The CMEA is facilitating the glucosides to penetrate your skin and cause a form of dermatitis. Adding Lamesoft PO-65 would result in the same. As you will see I am not a fan of glucosides, I have tried them in the past and as a result will not include them in any product. I suggest you use a better surfactant mix, without glucosides.
You can easily test this to see if I am correct. Prepare an alternative blend of surfactants without glucosides. E.G., ALS/ALES/CAPB. Try that with and without CMEA. -
Glucosides have seen rising sensitivity reaction incidence particularly in people over 40 with a history of atopic dermatitis, more women than men.
So might be worth trying something else!

I think you are right guys. I reduced the APGs to a total of 10% and the itchiness and drying was significantly reduced. I had this notion that APGs are mild and moisturizing. It seems that CMEA + APGs are a bad combination.
I’ll try other surfactants to further validate. Thank you so much for your thoughts
