Q3 Rheological Sameness

Compare the oscillatory-rheology fingerprint of a test topical semisolid against the reference (RLD). Each frequency sweep is reduced to a power-law fingerprint (storage/loss moduli, loss tangent, springpot order α). Verdict: FDA Q3 microstructure sameness — test/reference ratio within 90–111% (primary) — with the reference's ±3σ characterized range as supporting context.

Reference label (optional) Reference frequency ω_ref (optional)

One row per point: product, freq (rad/s), gp (G', Pa), gpp (G'', Pa), replicate. The reference is the product labelled rld / ref / reference (or set it above). ≥ 3 reference replicates recommended for a defensible ±3σ band.
