Sodium Sorbate
INCI: Sodium Sorbate
A gentle, well-tolerated preservative that helps keep your products fresh and safe from microbial growth.
In plain English
Sodium Sorbate is a preservative that stops bacteria, mold, and yeast from growing in your skincare products. It's the salt version of sorbic acid, which is a naturally occurring compound found in some berries. In your lotion or cleanser, it works quietly in the background to keep the product from spoiling, so you don't have to worry about contamination. It's considered very gentle and is a popular choice for sensitive skin formulas.

What it is
Sodium Sorbate is the sodium salt of sorbic acid, a naturally occurring unsaturated fatty acid. It is produced synthetically for cosmetic use and is a white, crystalline powder that dissolves easily in water.
How it works
Sodium Sorbate works by disrupting the cell membranes of microorganisms like bacteria, mold, and yeast. It prevents them from growing and multiplying, which keeps your cosmetic product stable and safe to use over its shelf life. It is most effective in products with a slightly acidic to neutral pH.
Pros
Gentle on skin
Sodium Sorbate has a very low irritation and sensitization profile, making it a top choice for sensitive skin formulations and baby products.
Effective preservation
It reliably prevents the growth of common spoilage organisms like mold and yeast, helping your products stay fresh and safe for longer.
Cons and cautions
pH sensitive
Sodium Sorbate works best in formulas with a pH below 6.5. In higher pH products, its preservative power drops significantly, requiring additional preservatives.
Not broad-spectrum alone
It is more effective against fungi and yeast than against all types of bacteria. It is often paired with other preservatives to ensure complete protection.
Best for
- Anyone looking for a gentle, effective preservative in their skincare
- People with sensitive or reactive skin who want to avoid harsher preservatives
Use caution if
- Those with a known allergy to sorbic acid or its salts (very rare)
