Schwarzkopf Igora Royal Oil Developer 9% 30 Volume

This Schwarzkopf Igora Royal Oil Developer is a 9% hydrogen peroxide formula supplied in a 1 litre bottle. It is intended for professional colourists and experienced home users who need to lift natural pigment by two to three levels or cover resistant white hair. The oil-enriched base helps protect the hair fibre during the oxidation process.

Sustained processing performance

During the full development time the 30 volume strength maintains consistent lifting power without rapid decay, allowing even, predictable lightening from roots to ends. The oil carrier buffers the alkaline reaction so the mixture stays stable on the hair, reducing the risk of banding or uneven porosity when processing resistant white coverage.

Practical limits of 30 volume peroxide

At 9% concentration this developer cannot safely achieve lifts beyond three levels without excessive damage, so darker bases requiring four-level lifts need a higher volume. It is not formulated for direct scalp bleaching or high-lift blonde series, and the 1 litre format suits salon throughput rather than occasional single-application use.

Questions about this item

Does the 9% / 30 volume strength generate heat during the processing time?

The developer works at room temperature; any warmth felt comes from the chemical reaction with colour cream, not from the liquid itself.

What Igora Royal colour cream is required to use this 1 L developer?

It is designed to mix with Schwarzkopf Igora Royal permanent colour shades, including the 9.5 series for tone-on-tone or pastel results.

Can the 30 volume developer be used with colour creams formulated for 10 or 20 volume?

Yes, the same Igora Royal colour creams are used across 10, 20, 30 and 40 volume developers; only the lift level changes.
