Sodium hydroxymethane
sulfonate, also known as Sodium formaldehyde bisulfite (bisulphite), used as a
preservative in cosmetic compositions. The sodium hydroxymethane
sulfonate is used to improve the color stability of rosin resins and it has
properties of both formaldehyde and sodium bisulfite. It is typically
present in an amount of from 0.05% to 5.0%, preferably about 0.25%, based on
the weight of the rosin resin.
Sodium hydroxymethane sulfonate, also known chemically
as sodium formaldehyde bisulfite, NaCH3 OSO3, is a
white, water-soluble rather inexpensive powder which forms colorless and
odorless solutions. Under alkaline conditions this compound is believed to
slowly hydrolyze into formaldehyde and sodium bisulfite which by their
presence render the desired antibacterial and antioxidant preservative
properties, respectively. A preservative aqueous cosmetic composition having
an antioxidant and an antibacterial property imparted by a single component
is, therefore, obtained by treating the cosmetic composition with a
sufficient amount of sodium hydroxymethane sulfonate to exert a preservative
effect to the cosmetic formulation when the pH of the formulation is about
7.0 or higher. Although the sodium salt of hydroxymethane sulfonate is the
compound of choice, other salts of hydroxymethane sulfonate wherein the
cation is selected from the group consisting of potassium, ammonium and the
like and mixtures thereof, may also be employed according to the teaching of
the present invention.
Corn syrups, honey and polyglycols, many of which are inexpensive, possess
properties including that of being humectants, which render them useful in
cosmetic preparations. The slow, time-released, anti-browning property
together with the anti-microbial activity of the compound makes it possible
to prepare cosmetic formulations wherein said formulation has corn syrup as
an ingredient.
It is also used to control
metallic impurities in Bright Nickel Bath
