CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application is a 37 C.F.R. .sctn. 1.53(b) divisional of U.S. application Ser. No. 11,332,161 filed Jan. 17, 2006, which is a 37 C.F.R. .sctn. 1.53(b) continuation of 10/417,122, filed Apr. 17, 2003, which claims priority on Japanese Application Nos. 2002-114282 filed Apr. 17, 2002, and 2002-217686 filed Jul. 26, 2002. The entire contents of each of these applications is hereby incorporated by reference. TECHNICAL FIELD OF THE INVENTION [0002] The present invention relates to new compounds for a softener, a production process therefor and compositions containing the same. Furthermore, the present invention relates to a production process for softener compositions and softener compositions obtained by means of production process. PRIOR ART [0003] Triethanolamine salt and the like has been heretofore known, for example sulfuric acid amine salt like an alkyl or alkenyl sulfuric amine salts, and used in various kinds of detergents and softeners. However, no sufficient study has been so far conducted on a neutralization compound between a sulfated compound having a long chain alkyl or alkenyl group and an amine having a long chain alkyl or alkenyl group. [0004] Liquid softeners having been traditionally used in individual households contain a water non-soluble quaternary ammonium salt as a softening agent. Moreover, a study has been conducted on combination of an anionic surfactant therewith for the purpose of improving hand touch feeling and a softening effect. Disclosed in U.S. Pat. No. 4,447,343 is a technique using a combination of a quaternary ammonium compound with an anionic surfactant. Disclosed in U.S. Pat. No. 4,751,009 is a softener composition containing a cationic surfactant and a salt of a specific amine and an anionic surfactant. Disclosed in U.S. Pat. No. 4,661,270 is a transparent softener composition containing an anionic surfactant and a cationic surfactant. Besides, the present inventors propose a softener composition containing a monoalkyl cationic surfactant and an anionic surfactant for improvement on hand touch feeling in JP-A 2001-200474. [0005] As to production processes for a softener, on the other hand, a method has been studied that suppresses an increase in viscosity and gelation in compounding. Disclosed in JP-A 10-298867 is a technique that an ammonium compound and sugar-alcohol are kneaded in advance, followed by mixing them with water under a high shearing. Disclosed in JP-W 2001-526304 is a production process for a softener in which a molten softening agent is dispersed in water. Disclosed in JP-A 5-106166 is a production process for a softener including a process in which a melt of a softening agent and a nonionic surfactant is produced. Furthermore, disclosed in U.S. Pat. No. 4,751,009 is a production process in which a sulfonic acid surfactant salt of a specific amine compound is mixed into a quaternary ammonium salt in advance. As described in U.S. Pat. No. 4,751,009, however, gelation frequently occurs in producing a softener composition containing an anionic surfactant and an amine compound. In order to avoid gelation, it is necessary to agitate softening agents under a high shearing energy. Moreover, even with such agitation adopted, a gel-like material locally remains, but is not easily dispersed even when the composition is added into water for rinsing clothes and then is agitated, resulting in another problem of reducing a softening effect. An improvement has been demanded. DISCLOSURE OF THE INVENTION [0006] It is an object of the present invention to provide a neutralization compound between a sulfuric acid or sulfonic acid having a long chain alkyl or alkenyl group and an amine having a long chain alkyl or alkenyl group, useful as a softener and a production process therefor. [0007] It is another object of the present invention to provide a production process for a softener composition containing an amine compound and an anionic surfactant, under which gelation of the softener composition is suppressed, resulting in providing a sufficient softening effect.
