Understanding These Tests for BBlunt High Shine Conditioning Hair Colour Coffee Natural Brown (4.31)
PPD Content
The laboratory reported PPD content as 0.71% w/w in the tested colourant sample.
PPD (para-phenylenediamine) is a hair-colouring ingredient that can cause allergic reactions in some individuals. This report measures the PPD content but does not establish that the formulation is suitable for everyone.
Colourant pH
The tested colourant recorded a pH of 9.28. This indicates an alkaline formulation.
The measurement was performed under IS:8481:2005.
Developer pH
The developer recorded a pH of 4.40. This measurement relates to the developer before mixing with the colourant.
Hydrogen Peroxide Assay
The laboratory measured hydrogen peroxide at 6.51% w/w in the developer sample.
This test records the peroxide content; it does not establish grey coverage or colour-retention performance.
Viscosity
The colourant viscosity was 1256781 cps and the developer viscosity was 6628 cps under the specified laboratory test conditions.
Viscosity measures resistance to flow.
Foam Height
The developer recorded a foam height of 56 mm in a 2% solution.
This laboratory measurement does not independently demonstrate hair-colouring effectiveness.
