Succinic Acid ●
TL;DR. This ingredient is primarily used as a pH adjuster and buffering agent, with secondary value in blemish-focused and mild exfoliating formulas. It helps tune formula acidity and can support a smoother skin feel in water-based products.
What does Succinic Acid do in a cosmetic formula?
This ingredient is primarily used as a pH adjuster and buffering agent, with secondary value in blemish-focused and mild exfoliating formulas. It helps tune formula acidity and can support a smoother skin feel in water-based products.
Is Succinic Acid clean?
From a clean-beauty perspective, this ingredient is generally well tolerated and not a common restricted-list concern. Like other acidic materials, it may sting in low-pH formulas or on very reactive skin, so irritation potential depends mostly on concentration and final formula pH.
Is Succinic Acid sustainable?
This material can be made through fermentation from renewable sugar feedstocks or through petrochemical routes. It is water soluble and readily biodegradable, with low concern for environmental persistence.
Is Succinic Acid COSMOS-approved?
It is compatible with COSMOS-natural and COSMOS-organic formulation approaches when sourced and processed according to the standard’s permitted input rules. It fits Green Chemistry well when bio-fermented, because it uses renewable feedstocks, has good biodegradability, and does not require persistent solvents in the finished ingredient.
How does Succinic Acid work chemically?
The molecule is a small four-carbon dicarboxylic acid with two acid groups, giving it buffering behavior around pKa values near 4.2 and 5.6. It is stable in typical cosmetic pH ranges and is usually used at low levels for pH control, with higher low-single-digit use possible in targeted leave-on formulas.
