Abstract

Dimethicone copolyol sulfosuccinate surfactant compounds having low-odor characteristics are disclosed. The low-odor dimethicone copolyol sulfosuccinate is substantially free from propionaldehyde and acid-releasable precursors of propionaldehyde, thereby substantially eliminating the cosmetically undesirable odor characteristic of conventional dimethicone copolyol sulfosuccinate surfactants. The low-odor dimethicone copolyol sulfosuccinates are suitable for use as surfactants in household or personal care products and applications.

Description

FIELD OF THE INVENTION

[0001] This invention relates to sulfosuccinate surfactants. More particularly, this invention relates to silicone-based sulfosuccinate surfactants having low-odor characteristics. BACKGROUND OF THE INVENTION

[0002] Sulfosuccinate surfactants have been used in the cosmetic industry primarily to improve the mildness of skin cleansers, shampoos and other personal care products. Such surfactants are usually diesters or monoesters, with the monoester being preferred because of its mildness and foam enhancement properties. Prior to the development of dimethicone copolyol sulfosuccinates, which are disclosed in U.S. Pat. No. 4,717,498 to Maxon, which is incorporated herein by reference, primarily two half ester or monoester derivatives had been used for shampoos. Such derivatives included derivatives of monoalcohol amides, such as oleamide MEA, oleamide IPA and undecylenamide MEA, and derivatives of fatty alcohols and ethoxylated alcohols, such as lauryl, laureth an...
