Description

Sodium sulfite is an antioxidant-based preservative that is used in cosmetics and skincare products. Sodium sulfite is used to prevent the growth of bacteria and mold and extend the shelf-life and longevity of formulations. Sodium sulfite is also used to alter the structure of the hair, either straightening or creating waves in the hair.

Sodium sulfite is a sodium salt of sulfurous acid with the chemical formula Na2SO3. It can be prepared by reacting sulfur dioxide, soda ash or sodium carbonate, and water. The product of this reaction is sodium bisulfite, which is then treated with excess soda ash to obtain sodium sulfite. Sodium sulfite is a white powder with no odor and a slightly salty taste.

In addition, to use in the cosmetic industry, sodium sulfite is used as a food preservative to prevent dried fruit from discoloring and for preserving meats. However, sodium sulfite degrades both vitamins B1 and E, which means that it cannot be added to foods that contain these vitamins. Sodium sulfite is an essential ingredient in the pulp and paper industry.

The Benefits of Sodium Sulfite:
In cosmetics and personal care products, sodium sulfite functions as an antioxidant preservative and a hair-waving/straightening agent.

– Antioxidant
As an antioxidant preservative, sodium sulfite works by protecting the other ingredients in a formulation from oxidation. Oxidation is naturally occurring process that happens when some ingredients are exposed to air. Oxidation results in destabilization of ingredients and can result in rancidity, changes in color and changes in texture. Adding an antioxidant preservative like sodium sulfite will make the product less susceptible to degradation when exposed to environmental elements.

– Hair
In addition to use as an antioxidant preservative, sodium sulfite functions as a hair-waving/straightening agent. It is often used in combination with sodium metabisulfite and sodium sulfate in products used to straighten the hair and in permanent waves. Other hair care products that use sodium sulfite include hair bleaches, hair dyes, colors and tints.

– Preservative
Inhibits the development of microorganisms in cosmetic products.

– Reducing
Changes the chemical nature of another substance by adding hydrogen or removing the oxygen
