Sodium Benzoate. May Contain: Titanium Dioxide ●
TL;DR. This ingredient is primarily a preservative for water-based formulas, helping control yeast, mold, and some bacteria. It performs best in acidic products such as cleansers, toners, shampoos, and creams.
What does Sodium Benzoate. May Contain: Titanium Dioxide do in a cosmetic formula?
This ingredient is primarily a preservative for water-based formulas, helping control yeast, mold, and some bacteria. It performs best in acidic products such as cleansers, toners, shampoos, and creams.
Is Sodium Benzoate. May Contain: Titanium Dioxide clean?
From a clean-beauty perspective, it is widely accepted and generally well tolerated at permitted cosmetic levels. The main formulation caveat is that very acidic systems with ascorbic acid, heat, light, and trace metals need careful control to limit unwanted side reactions.
Is Sodium Benzoate. May Contain: Titanium Dioxide sustainable?
This material is usually made through conventional industrial chemistry, often from petrochemical feedstocks, though it is chemically simple and readily biodegradable. It does not raise the same persistence or bioaccumulation concerns associated with many long-chain silicones or fluorinated materials.
Is Sodium Benzoate. May Contain: Titanium Dioxide COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards as an approved preservative within use limits. Its Green Chemistry profile is solid because it is effective at low levels, water-compatible, and biodegradable, although the common feedstock route is not typically renewable.
How does Sodium Benzoate. May Contain: Titanium Dioxide work chemically?
The molecule is an aromatic carboxylate salt that becomes more active as pH drops, with best preservative performance generally below pH 5 and reduced efficacy near neutral pH. Typical cosmetic use levels are about 0.2% to 1.0%, often paired with chelators or complementary preservatives to broaden coverage.
