Sodium Perborate Tetrahydrate
Sodium perborate tetrahydrate is a white, odorless powder used primarily as a bleaching agent and oxygen source in laundry detergents and cleaning products. It falls under HTS 2840.30.0050 as a peroxoborate (perborate), specifically classified as 'other' peroxoborates excluding the common monohydrate form. This chemically defined inorganic compound releases hydrogen peroxide when dissolved in water, making it essential for stain removal.
Sodium Perborate Monohydrate
Sodium perborate monohydrate is an anhydrous form of the perborate salt used in high-performance detergents and denture cleaners for its stable oxygen bleach properties. Classified under HTS 2840.30.0050 as 'other' peroxoborates, it distinguishes from tetrahydrate by its single water molecule content. It decomposes to release active oxygen for effective whitening without chlorine.
Potassium Peroxoborate
Potassium peroxoborate is a less common alkali metal perborate used in specialized bleaching applications and as an oxygen source in chemical synthesis. It qualifies under HTS 2840.30.0050 as 'other' peroxoborates, being a chemically defined inorganic compound of boron with peroxy groups. Its solubility and stability make it suitable for niche industrial cleaning formulations.
Calcium Peroxoborate
Calcium peroxoborate is an alkaline earth peroxoborate utilized in dental bleaching products and specialty oxidants. It is classified in HTS 2840.30.0050 as 'other' peroxoborates, a chemically defined compound fitting Chapter 28 definitions. Its lower solubility suits slow-release applications in oral care.
Peroxoboric Acid
Peroxoboric acid, in stabilized form, acts as a precursor for perborate salts in laboratory and fine chemical production. HTS 2840.30.0050 covers it as an 'other' peroxoborate per Chapter 28 acid provisions. It represents the parent acid structure with peroxy functionality.
