Sodium Anistate ●
TL;DR. This ingredient functions mainly as an antimicrobial preservative booster, helping water-based formulas control microbial growth. It is often paired with organic acid salts, glycols, or other preservation systems for broader coverage.
What does Sodium Anistate do in a cosmetic formula?
This ingredient functions mainly as an antimicrobial preservative booster, helping water-based formulas control microbial growth. It is often paired with organic acid salts, glycols, or other preservation systems for broader coverage.
Is Sodium Anistate clean?
From a clean-beauty perspective, it is generally well tolerated and has little restricted-list friction. Its main formulation caveat is pH dependence, since performance improves in mildly acidic systems.
Is Sodium Anistate sustainable?
This material can be made from bio-based aromatic feedstocks or nature-identical production routes, depending on supplier. It is expected to biodegrade well and is not associated with persistence or bioaccumulation concerns.
Is Sodium Anistate COSMOS-approved?
It is permitted in COSMOS-natural and COSMOS-organic formulations when the source and manufacturing route meet the standard. It aligns reasonably well with Green Chemistry because it can be bio-based, used at low levels, and supports lower-burden preservation systems.
How does Sodium Anistate work chemically?
The molecule is an aromatic carboxylate salt that becomes more antimicrobial as the formula pH shifts toward the protonated acid form. Typical use levels are about 0.1% to 0.3%, often in formulas below roughly pH 5.5 and paired with complementary preservative boosters for wider spectrum control.
