Question 1

What does Sodium Citrate. May Contain/Peut Contenir : Iron Oxides (Ci 77491 do in a cosmetic formula?

Accepted Answer

This ingredient is primarily a pH buffer and chelating aid, helping formulas hold a stable acidity level while binding trace metal ions that can affect color, scent, and stability.

Question 2

Is Sodium Citrate. May Contain/Peut Contenir : Iron Oxides (Ci 77491 clean?

Accepted Answer

It is broadly accepted in clean-beauty frameworks and is generally well tolerated at cosmetic use levels. It has no major restricted-list friction when used as a buffering or stabilizing ingredient.

Question 3

Is Sodium Citrate. May Contain/Peut Contenir : Iron Oxides (Ci 77491 sustainable?

Accepted Answer

This material is commonly made from fermentation-derived organic acid neutralized with a sodium source. It has a favorable environmental profile because it is water soluble, readily biodegradable in its organic portion, and not associated with persistence or bioaccumulation concerns.

Question 4

Is Sodium Citrate. May Contain/Peut Contenir : Iron Oxides (Ci 77491 COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards when produced and used according to the standard’s requirements. Its profile fits Green Chemistry well, especially when fermentation-based feedstocks and simple neutralization are used.

Question 5

How does Sodium Citrate. May Contain/Peut Contenir : Iron Oxides (Ci 77491 work chemically?

Accepted Answer

The molecule is a sodium salt of a small tricarboxylic organic acid, which lets it buffer pH and modestly bind metal ions in water-based systems. Typical use is often around 0.1% to 1%, commonly paired with an acid partner to set pH in the mildly acidic to neutral range.
