Niacinamide USP

Why this grade

Niacinamide is the workhorse of every brightening and barrier line — which is exactly why spec drift matters. Ours is USP43-grade nicotinamide with residual nicotinic acid held under 0.1%, so formulators avoid the flush response that cheaper lots carry into finished products.

Synthesized in our own line and released on triple-phase analysis, each lot ships with a COA that reads the same in your QA system as it does in ours. Typical use level 2-5%; stable across pH 5.0-8.0 and through standard heat processing.

Key benefits

• Residual nicotinic acid <0.1% — no flush response in finished product
• Batch-to-batch assay consistency: 99.5-99.9% band, no re-formulation needed between lots
• Stable with zinc PCA, AHA salts and most preservative systems
• USP43 monograph compliance with ICH Q3C residual solvent verification

Technical specification

Ingredient profile

Niacinamide is the workhorse of every brightening and barrier line — which is exactly why specification drift matters. This is USP43-grade nicotinamide synthesized in our own line, released on triple-phase analysis, with residual nicotinic acid held under 0.1%.

That residual-nicotinic-acid control is the difference between a comfortable 2–5% use and the flush response cheap lots can trigger. The assay band of 99.5–99.9% means your formula does not need re-optimization between drums.

Stable across pH 5.0–8.0 and through standard heat processing, it combines cleanly with zinc PCA, AHA salts, bakuchiol and most preservative systems. Every lot ships with batch COA, MSDS and allergen profile — the documentation culture explained in our quality section.
