What Is It?
Sodium Chloride, or table salt, is a white crystalline solid. In cosmetics and personal care products, Sodium Chloride is used in the formulation of oral hygiene products, shampoos, fragrance, skin, hair, nail, cleansing, suntan, makeup and bath products.
Why Is It Used?
Sodium Chloride polishes the teeth, reduces oral odor, or otherwise cleanses or deodorizes the teeth and mouth. Sodium Chloride also imparts a flavor or a taste to a product. It can also increase the thickness of the aqueous (water) portion of cosmetics and personal care products.
Sodium Chloride occurs naturally in seawater and as the mineral halite. Sodium Chloride is essential to biological organisms and is found in most tissues and body fluids. The sodium and chlorine elements of Sodium Chloride play a diverse and important role in many physiological processes, including the transport of nutrients and waste, nervous system functions, and water and electrolyte balance.
The Food and Drug Administration (FDA) reviewed the safety of Sodium Chloride and approved its use as an active ingredient in Over-The-Counter (OTC) drug products for the eyes at concentrations of 2 to 5%. In addition to being an important component of food, FDA includes Sodium Chloride on its list of substances considered Generally Recognized as Safe (“GRAS” is an acronym for the phrase Generally Recognized As Safe. Under sections 201(s) and 409 of the Federal Food, Drug, and Cosmetic Act (the Act), any substance that is intentionally added to food is a food additive, that is subject to premarket review and approval by FDA, unless the substance is generally recognized, among qualified experts, as having been adequately shown to be safe under the conditions of its intended use, or unless the use of the substance is otherwise excluded from the definition of a food additive.) as a substance migrating to food from packaging. The FDA also regulates labeling of table salt, and regulates labeling statements on food regarding levels of Sodium Chloride the food product contains. The Cosmetic Ingredient Review (CIR) was established in 1976 as an independent safety review program for cosmetic ingredients. The CIR Expert Panel consists of independent experts in dermatology, toxicology, pharmacolgy and veterinary medicine. The CIR includes participation by the U.S. Food & Drug Administration and the Consumer Federation of America. (CIR) has deferred evaluation of this ingredient because the safety has been assessed by FDA. This deferral of review is according to the provisions of the CIR Procedures.
The FDA’s Select Committee on GRAS Substances (SCOGS) concluded that there was no evidence in the available information on Sodium Chloride in dry food packaging that demonstrates, or suggests reasonable grounds to suspect, a hazard to the public when it is used at levels that are now current or might reasonably be expected in the future.
Link to FDA Code of Federal Regulations for Sodium Chloride
Sodium Chloride may be used in cosmetics and personal care products marketed in Europe according to the Under the general provisions of the cosmetics regulation of the EU, ingredients appearing on the following function-specific annexes must comply with the listed restrictions and/or specifications: colorants (Annex IV), preservatives (Annex V), UV filters (Annex VI) and other ingredients with specific concentration limits and/or other restrictions (Annex III). Ingredients specifically prohibited from use in cosmetic products are listed in Annex II. Other ingredients listed in the EU cosmetic ingredient database (CosIng) may be used without restrictions..
