about same surfactant but different supplier problem.
1. Hi, I need some insight about Cocamidopropyl betaine that I often use in my formula. The first supplier that I bought comes with very dark yellow color. He stated it is Swiss (i believe it is BASF although he doesn’t say the trademark/supplier name). The second supplier, comes with a very transparent white (no color), and he said it is from KAO (amphitol 55AB).
I checked both SDS, and the active matter is almost same (around 30%).
I tried both in a formula without color and both work succesfully to thicken my surfactant, but of course the yellow Cocamidopropyl betaine will cause the final product to be slight yellowish clear product.
Is Cocamidopropyl betaine suppose to be yellowish or transparent clear? (I’m just worried that it have effect in the long term).
2. I also have questions about Decyl glucoside. Why do decyl glucoside smells really bad and strong? (is it just me?) It gives big impact on the final product aroma, and 1% fragrance oil is not enough to mask that bad aroma from decyl glucoside.
I tried all other glucoside family (lauryl glucoside, coco glucoside) and it has no aroma, but I really want to use Decyl as it gives the best foam and mildness.
Thank you and really hope to hear from you guys that ever use this surfactant.
