What does Dropps mean by "clean ingredients"?

We hold our formulas to a higher ingredient standard — independently verified by third-party certifiers, not self-declared. That means every ingredient is evaluated for human and environmental safety before it makes it into a pod. Our laundry detergent formulas is free from optical brighteners, phosphates, artificial dyes, chlorine bleach, parabens, and phthalates — and certified by Cradle to Cradle Material Health, National Psoriasis Foundation, and USDA Certified Biobased.
