12 Principles of Green Chemistry: Principle 4—Designing Safer Chemicals
Chemical products should be designed to affect their desired function while minimizing their toxicity.
Chemical products should be designed to affect their desired function while minimizing their toxicity.
12 Principles of Green Chemistry: Principle 5—Safer Solvents and Auxiliaries. This product utilizes reduced volumes of auxiliary substances that are less hazardous.
12 Principles of Green Chemistry: Principle 8—Unnecessary derivatization (use of blocking groups, protection/ deprotection, temporary modification of physical/chemical processes) should be minimized or avoided if possible, because such steps require additional reagents and can generate waste.
