in an attempt to make a mild shampoo for myself, my formula below caused my face to become red/rashy/irritated the hours following my shower. It basically looks like i have a sunburn.
why is my formula causing this?
V1- red rashy face/“sunburn-like”
cocamidapropyl hydroxysultaine 3%
coco glucoside 12%
total active 8ASM
cetyl alcohol 0.5%
coco oil 0.2%
cationic guar gum 0.5%
xanthan gum 0.5%
no preservative. i make it, use it, and dump it same day. (work in v small batches)
V 2 - rashy, very dried out face
coco glucoside 9%
SCI prill 2%
total asm 10-11
how are companies like Tom’s of Maine able to make mild, minimalist shampoos with
decyl glucoside+glycerin+salt+xanthan gum...yet my minimalist copy cat versions is just harmful to my skin?
thank you in advance!
