MALONIC ACID ●
TL;DR. This ingredient is primarily used as a pH adjuster and buffering acid, helping formulas reach and hold a more acidic pH. It can also support mild exfoliating or clarifying positioning when used in acidic leave-on products.
What does MALONIC ACID do in a cosmetic formula?
This ingredient is primarily used as a pH adjuster and buffering acid, helping formulas reach and hold a more acidic pH. It can also support mild exfoliating or clarifying positioning when used in acidic leave-on products.
Is MALONIC ACID clean?
From a clean-beauty perspective, this ingredient is generally straightforward and is not a common restricted-list concern. Like many low-pH acids, its skin feel depends on concentration and final formula pH, with higher acidity increasing sting or irritation potential.
Is MALONIC ACID sustainable?
This material is readily biodegradable and does not raise persistence or bioaccumulation concerns. It can be made synthetically or from bio-based routes, so sourcing quality depends on the supplier and manufacturing pathway.
Is MALONIC ACID COSMOS-approved?
It can fit COSMOS-natural or COSMOS-organic frameworks when sourced and processed through approved routes, while conventional synthetic supply may not qualify for certified natural formulas. Its Green Chemistry profile is favorable when bio-based or fermentation-derived, especially because it is small, water-soluble, and biodegradable.
How does MALONIC ACID work chemically?
The molecule is a three-carbon dicarboxylic acid with two carboxyl groups, giving pKa values around 2.8 and 5.7 and strong water solubility. Use level is usually set by the target pH rather than a fixed percentage, and it should be balanced carefully in emulsions and preservative systems because pH shifts can affect stability and antimicrobial performance.
