A textile chemistry or conservation source documents that sodium hypochlorite bleach is a strong oxidizing agent capable of rapidly decolorizing dyed cotton fabrics. Evidence role: mechanism; source type: education. Supports: Strong liquid bleach can lighten dark blue jeans quickly.. Scope note: The source may describe cotton or dyed textiles generally rather than denim jeans specifically.
[^2]: "Regenerable antimicrobial finishing of cotton with nitrogen ...", https://bioresources.cnr.ncsu.edu/resources/regenerable-antimicrobial-finishing-of-cotton-with-nitrogen-plasma-treatment/. Textile conservation guidance explains that chlorine bleaches can weaken cellulose-based fibers such as cotton through oxidative degradation. Evidence role: mechanism; source type: institution. Supports: Chlorine bleach can damage cotton fibers in denim.. Scope note: The degree of damage depends on bleach concentration, exposure time, rinsing, and fabric condition.
[^3]: "Common Bases", http://hyperphysics.phy-astr.gsu.edu/hbase/Chemical/basecom.html. A chemistry reference identifies sodium bicarbonate as a weak alkaline compound in water, providing context for its use as a mild alkaline washing additive. Evidence role: definition; source type: encyclopedia. Supports: Baking soda is a mild alkali that may be used in wash water.. Scope note: This supports the alkalinity of baking soda, not direct proof that it reliably lightens indigo denim.
[^4]: "Effect of Different bleaching agents on cotton fabric properties", https://www.academia.edu/31914826/Effect_of_Different_bleaching_agents_on_cotton_fabric_properties. Textile bleaching literature distinguishes hydrogen peroxide bleaching from hypochlorite bleaching and notes that process conditions influence fiber damage and bleaching rate. Evidence role: expert_consensus; source type: paper. Supports: Hydrogen peroxide is generally treated as a different, often more controllable textile bleaching agent than chlorine bleach.. Scope note: This supports a comparative context only; it does not prove the specific home recipe is gentler than every chlorine-bleach dilution.
