DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/JP95/02117, filed Oct, 16, 1995.
TECHNICAL FIELD
This invention relates to non-ionic surfactants, emulsified compositions, dispersions and a process for the preparation of glycoside compounds possessing surface activity.
BACKGROUND ART
In general, non-ionic surfactants are known to be excellent in mild property to skin and safety and are widely utilized as a foaming agent for tooth cream, a detergent for kitchen, and cosmetics such as skin care or hair care.
A number of substances, for example, an alkylene oxide adduct such as an ethylene or propylene oxide adduct of a higher alcohol, a glycerol fatty acid ester and a polyglycerol fatty acid ester, sugar alcohol esters such as a sorbitan fatty acid ester, and oligosugar esters such as a sucrose fatty acid ester and a maltose fatty acid ester are known as non-ionic surfactants.
These non-ionic surfactants respectively possess a variety of characteristics; for example, they are excellent in solubilizing oils like an ethylene oxide or propylene oxide adduct of higher alcohols, or they are excellent in emulsifying power like as a sucrose fatty acid ester or a glycerol ester. However, non-ionic surfactants are generally poor in foaming power so that they are significantly inferior to anionic surfactants such as sodium laurylsulfate for use in products where good foaming is demanded such as a foamant for tooth cream, a detergent for kitchen, and cosmetics for skin care and hair care. It is therefore a current status that they cannot be used singly and are improved in foaming power by using various additives or other surfactants jointly.
On the other hand, various glycosides are known as a non-ionic surfactant which is high in safety for human body (e.g. Japanese Laid-open Patent Applns. Nos. Sho.60-204794, Hei.4-244094 and 6-145188).
However, these glycosides have a defect that they are inferior in foaming power like the aforesaid non-ionic surfactants and moreover they are poor in foaming stability.
Further, these glycosides are not satisfactory in aspects of emulsifying ability for oils and dispersing ability for solid particles.
The subjects of the present invention aimed at are as follows: and is excellent in foaming power and foam stability, body and is excellent in emulsifying power for oils and in emulsion stability, excellent in dispersibility of fine solid particles and in dispersing stability, and glycoside which is excellent in surface activity.
Other subjects of the present invention will become apparent more fully from the following descriptions.
DISCLOSURE OF THE INVENTION
As a result of extensive researches to solve the aforementioned subjects, the present inventors have accomplished the present invention.
In accordance with the present invention, there is provided the following inventions: hydroxyl group connected to the carbon atom in anomeric position among q hydroxyl groups connected to the saccharide compound of the formula R.sup.1 for an aliphatic group having 1-12 carbon atoms, hydroxyl groups connected to the carbon atom in anomeric position among q hydoxyl groups connected to the saccharide compound of the formula (OH)O!.sub.x --H (1<x.ltoreq.7), and R.sup.2 for an aliphatic group having 13-22 carbon atoms; emulsified in the presence of an emulsifying agent, which comprises a emulsifying agent; presence of a dispersing agent, which comprises a glycoside compound of surface activity which comprises reacting a saccharide compound of the groups connected to the saccharide skeleton, in the presence of a solid acid catalyst with a glycerol derivative of the following general formula a number of 1-7; and surface activity which comprises reacting a saccharide compound of the groups connected to the saccharide skeleton, in the presence of an acid catalyst and an inorganic sulfate with a glycerol derivative of the number of 1-7.
A monosaccharide, oligosaccharide and saccharide polymerizate are included saccharides will now be explained hereunder in detail. monosaccharide.
