Niacinamide B3 ●
TL;DR. This ingredient is a water-soluble skin-conditioning active used to support barrier appearance, uneven tone, excess shine, and the look of fine lines. It is typically added to the water phase rather than used as a structural emulsifier or preservative.
What does Niacinamide B3 do in a cosmetic formula?
This ingredient is a water-soluble skin-conditioning active used to support barrier appearance, uneven tone, excess shine, and the look of fine lines. It is typically added to the water phase rather than used as a structural emulsifier or preservative.
Is Niacinamide B3 clean?
It is broadly accepted in clean-beauty frameworks and is generally well tolerated, though higher levels can cause temporary warmth, redness, or tingling in some users. The main review points are concentration, pH control, and supplier documentation rather than restricted-list concerns.
Is Niacinamide B3 sustainable?
This material is usually made by chemical synthesis, with some emerging bio-based or fermentation-linked routes. It is water soluble and expected to have low persistence, but its sustainability profile depends on feedstock source and manufacturing efficiency.
Is Niacinamide B3 COSMOS-approved?
It may be used in COSMOS-natural or COSMOS-organic products only when the grade and manufacturing route meet the standard’s permitted raw-material requirements, so approval is supplier-specific. From a Green Chemistry view, it scores well on low use level and low persistence, but less well when made from conventional synthetic feedstocks.
How does Niacinamide B3 work chemically?
The molecule is a small, polar aromatic amide that dissolves readily in water and is commonly used around 2% to 5%, with some formulas going higher. It is most stable near mildly acidic to neutral pH, and formulators usually keep it away from very low pH systems to limit conversion to a flushing-prone related acid.
