I tried Dawn Platinum sold at my local Costco. (I had experience with Dawn Ultra, but this was my first time trying Dawn Platinum.)
Tap water 5,000ml
Dawn Platinum 180g
BLM 70g
Adjusted to ph 7.5 with citric acid
AM 9:00 / 6℃ / 86% humidity / less than 1m/s
Giant soap bubbles were easily created, but it was impossible to determine whether they were the result of the power of Dawn or favorable weather conditions.
The older version of Cucute has a surfactant percentage of 37%, and Dawn Platinum has 34.3% (as listed in the product labeling section). I feel that 18:1 to 20:1 is about right for Cucute. Dawn Platinum, however, gives a proper color profile at around 27:1. There is a significant difference when calculated by the amount of surfactant. There seems to be a difference in potential that cannot be discerned by percentage numbers.
