Sustainability Score

62%

While Sloomoo Institute uses some eco-friendly packaging and offers biodegradable slime options, their overall environmental impact remains significant due to plastic usage and chemical-based products. They demonstrate moderate transparency about ingredients but could improve supply chain disclosure. Their commitment to ethical labor practices is evident, though documentation is limited. Animal testing policies are clear and positive, but waste management practices need enhancement.
