Question 1

What does citric acid \ Organic Ingredients do in a cosmetic formula?

Accepted Answer

This ingredient is primarily used as a pH adjuster and buffering acid in skin, hair, and cleansing formulas. It can also support mild exfoliation at lower pH and help improve preservative performance by setting the formula’s acidity.

Question 2

Is citric acid \ Organic Ingredients clean?

Accepted Answer

This ingredient is well accepted in clean-beauty standards and is generally well tolerated at typical pH-adjusting levels. Eye or skin stinging can occur when formulas are made very acidic or when higher exfoliating levels are used.

Question 3

Is citric acid \ Organic Ingredients sustainable?

Accepted Answer

This material is commonly produced by fermentation of carbohydrate feedstocks, often from corn, sugar beet, or sugarcane. It is readily biodegradable and does not raise persistence or bioaccumulation concerns.

Question 4

Is citric acid \ Organic Ingredients COSMOS-approved?

Accepted Answer

This ingredient is permitted under COSMOS-natural and COSMOS-it standards when it meets the standard’s sourcing and processing requirements. It aligns well with Green Chemistry because it can be fermentation-derived, water soluble, readily biodegradable, and effective at low use levels.

Question 5

How does citric acid \ Organic Ingredients work chemically?

Accepted Answer

The molecule is a small it acid with three carboxyl groups and one hydroxyl group, which gives it strong buffering and metal-chelating behavior in water-based systems. Typical use is often below 1% for pH adjustment, while exfoliating formulas may use higher levels and require careful control of final pH, usually in the acidic range.
