Sodium Perborate vs. Sodium Percarbonate — What's the Difference?
Sodium perborate is an oxygen bleach compound used in detergents and cosmetics, while sodium percarbonate is a solid peroxide that releases hydrogen peroxide and is also used in cleaning agents.
Difference Between Sodium Perborate and Sodium Percarbonate
Table of Contents
Sodium Perborate is a white, crystalline chemical compound that serves as an oxygen bleach in various cleaning products, particularly in detergents. On the other hand, Sodium Percarbonate is a chemical that, when dissolved in water, releases hydrogen peroxide, making it a popular ingredient in eco-friendly cleaning products and laundry detergents.
Both compounds are sources of active oxygen, which is why they are effective stain removers. Sodium Perborate, specifically, is often found in powdered detergents, acting as a stable source of active oxygen. Sodium Percarbonate, in contrast, is favored for its environmentally friendly nature, as it breaks down into water, oxygen, and soda ash.
While Sodium Perborate needs higher temperatures to activate its bleaching capability effectively, Sodium Percarbonate can work efficiently in cooler water. This makes the latter a more versatile cleaning agent, especially for cold-water washing.
Sodium Perborate exists in various hydrate forms, each with different water molecules attached to them. Sodium Percarbonate, however, is a simple combination of sodium carbonate and hydrogen peroxide, making its formulation straightforward.
Safety-wise, both chemicals should be handled with care. Sodium Perborate can release boron into the environment, which might be of ecological concern. Sodium Percarbonate, while generally safe and biodegradable, can still cause irritation upon direct contact or inhalation.
