DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/JP95/00242 filed Feb. 20, 1995.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to novel taurine derivatives, processes for producing the same, and cleanser compositions containing such taurine derivatives. Moreover, the present invention relates to other taurine derivatives which are useful as intermediates for synthesizing the above-mentioned taurine derivatives and are themselves useful as cleansers, a process for producing the same, and cleanser compositions containing such taurine derivatives. The present invention also relates to methods of washing hair or skin using such taurine deirvatives.
2. Discussion of the Background
In recent years, it has become demanded that the surfactants used as cleansers have excellent properties such as biodegradability, safety toward the skin, eyes and hair, foaming power, comfort in the use thereof, and rinsability as well as surface activity. Acylated amino acid surfactants, imidazoline surfactants, alkyl phosphate salts, saccharide surfactants such as alkyl glycosides have become widely employed as surfactants meeting the above demand.
Generally, these surfactants are costly and unsatisfactory in foaming power and detergency which are particularly important in the use as a cleanser, while they are excellent in other properties such as safety. Therefore, it is rare that these surfactants per se are independently used as the main ingredient of a cleanser such as a body cleanser and a shampoo. These surfactants are generally used together with a conventional anionic surfactant such as an alkyl sulfate, an alkyl ether sulfate and a fatty acid soap. Therefore, the development of a cleanser which is available at a low cost, is excellent in foaming power, detergency and comfort in the use thereof, and ensures high safety, is strongly demanded in the art.
SUMMARY OF THE INVENTION
Accordingly, it is one object of the present invention to provide novel surfactants.
It is another object of the present invention to provide surfactants with excellent biodegradability, safety toward the skin, eyes and hair, comfort in use, foaming power, rinsability and surface activity.
It is another object of the present invention to provide novel processes for producing such surfactants.
It is another object of the present invention to provide novel intermediates for preparing such surfactants.
It is another object of the present invention to provide novel compositions which contain such surfactants.
It is another object of the present invention to provide novel methods of washing hair or skin with such compositions.
It is another object of the present invention to provide novel methods of washing hair or skin with such surfactants.
These and other objects, which will become apparent during the following detailed description, have been achieved by the inventors' discovery that amide anionic surfactants having a sulfonic acid group and a carboxyl group as ionic groups and which are derived from taurine are excellent in foaming, detergency, comfort in use, rinsability, safety and biodegradability.
Thus, the present invention provides a taurine derivative represented by the following formula (1) which is available at a low cost, is excellent in foaming power, detergency and comfort in the use thereof, and ensures high safety, and also a process for producing the same: ##STR2## wherein R is a linear or branched alkyl or alkenyl group having 5 to 21 carbon atoms, and M.sub.1 and M.sub.2 are the same or different from each other and each independently is a hydrogen atom, an alkali metal atom, 1/2 (an alkaline earth metal atom), an ammonium group, a mono-, di-, tri- or tetraalkylammonium group having 1 to 22 carbon atoms in total, a mono-, di-, tri- or tetraalkenylammonium group having 2 to 22 carbon atoms in total, a mono-, di-, tri- or tetraalkanolammonium group having 2 to 8 carbon atoms in total, an N-alkylpyridinium group having 1 to 18 carbon atoms in the N-alkyl group, an N-alkenylpyridinium group having 2 to 18 carbon
