* An organic compound.


Primarily used as a pharmaceutical muscle relaxant, which works by blocking nerve impulses that are sent to the brain. In cosmetics, it's used as a preservative because of its anti-fungal and anti-bacterial properties. As a preservative, it prevents various products from running into issues such as such as viscosity changes, pH changes, emulsion breakdown, visible microorganism growth, color changes and disagreeable odor formation.  Secondary to anti-fungal nail treatments, this ingredient is mostly contained in products such as facial moisturizer, anti-aging treatment, sunscreen, foundation, eye cream, cleanser, mascara and concealer.

Safety Measures/Side Effects:

Chlorphenesin has been reported to cause irritation and contact dermatitis in many, particularly those with sensitive & dry skin. In addition, research has shown it relax the skeletal muscle, depress the central nervous system and cause respiratory depression (slow or shallow breathing) in infants. Considering this, the FDA dissuades pregnant/nursing women and small children from using personal care products containing this ingredient.

Many countries, such as Japan, have restricted its cosmetic use by giving it concentration limitations. The Cosmetic Ingredient Review (CIR) Expert Panel, chlorphenesinhas reviewed chlorphenesin and noted that it is well-absorbed when applied to the skin of rats; however, their concern was minimized because of the negative toxicity. Eczema and skin irritation were observed.

The Panel concluded that chlorphenesin is safe in the present practices of use and concentration.
