Low-odor dimethicone copolyol sulfosuccinate surfactant compositions |
摘要 |
Dimethicone copolyol sulfosuccinate surfactant compounds having low-odor characteriztics 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 characteriztic 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. |

1. A low-odor composition that is substantially free from propionaldehyde and acid-releasable precursors of propionaldehyde and suitable for use in cosmetic and personal care applications, the composition comprising a dimethicone copolyol sulfosuccinate produced by the steps of:
reacting a dimethicone copolyol with maleic anhydride to form a maleic monoester, the dimethicone copolyol being substantially free of propionaldehyde and acid-releasable precursors of propionaldehyde; and sulfonating the maleic monoester with a compound selected from the group consisting of an alkali metal sulfite, an alkaline earth sulfite, ammonium sulfite, an amino sulfite, and a combination of any of the foregoing with an amino alcohol. |
