Abstract

PURPOSE:To make it possible to show excellent emulsification capacity with respect to an oil phase, by containing a high molecular substance obtained by esterifying the carboxyl group of natural polysaccharide with propylene glycol, polyhydric alcohol and an oil phase component. CONSTITUTION:One kind or more high molecular substance obtained by esterifying the carboxyl group of natural polysaccharide having the carboxyl group in the molecule thereof with propylene glycol, water soluble alcohol having two or more hydroxyl groups (e.g., ethylene glycol) and an oil phase component (e.g., tallow) are contained to form an emulsifier composition. The used ratio of propylene glycol ester and water soluble alcohol is pref. within a range of 1:2- 1,000 by weight. Because the obtained emulsifier composition is uniform and a transparent or a translucent gel or a viscous liquid, it can be directly and suitably used in all fields such as food, cosmetics or feedstuff for example, as a sun-care jelly, a beauty liquid, edible jelly, medical jelly or a lubricant.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to propylene, which is a natural polysaccharide having an h-carboxyl group, which is generally known as a water-soluble polymer.
One or more polymers made from propylene glyphs and esters of carboxyl groups with a large number of carboxyl groups in the molecule, a carboxyl alcohol, an oil phase component, and water as necessary. An emulsified composition obtained by containing
The present invention also provides an oil-in-water emulsion composition obtained by adding an aqueous phase component to this emulsion composition.

In recent years, much research has been conducted on emulsification, a large number of emulsifiers have been developed, and emulsification technology has made remarkable progress, and extremely stable emulsions are now widely used in all industrial processes. However, most of them are nonionic surfactants containing polyoxyethylene chains, anionic surfactants such as fatty acid soaps, cationic surfactants, and amphoteric surfactants, which are used as emulsifiers and are harmful to the human body. However, the use of natural polymers as emulsifiers has been studied in recent years, and has been used industrially as emulsifiers in the production of oil-in-water emulsion compositions. It's coming. However, natural water-soluble polymers are emulsifiers whose specific temporal stability is stabilized by the so-called "surfactants" such as the above-mentioned nonionic surfactants due to the thickening effect of the polymer.

Therefore, the present inventors researched the development of an emulsion with uniform and fine particles by using natural substances with high human safety as an emulsifier. We have discovered a new emulsifying composition containing one or more polymers in the form of propylene glycol esters. That is, according to the present inventors, it exhibits excellent emulsifying power for the oil phase and forms a uniform and stable emulsion. That is, by combining a polyhydric alcohol that does not dissolve in oil, one or more types of polymers with carboxyl group glyfur ester in the molecule, and water as necessary, and adding an oil phase component to these. It has been discovered that an emulsion composition in which oil phase components are solubilized or uniformly dispersed as a microemulsion in polyhydric alcohol or water can be obtained, and furthermore, by adding water to this emulsion composition, uniform dispersion of fine particles can be obtained. The present inventors have discovered that a stable oil-in-water emulsion composition can be obtained, and have completed the present invention.

(The following is a blank space) The emulsion composition obtained by the present invention is a transparent or translucent viscous liquid or gel, and the oil-in-water emulsion composition to which water is added is an emulsion of milky white fine particles. These microparticle emulsions are in water.

The reason for this microparticulation is thought to be that the propylene glycol ester of the natural polysaccharide interacts with the polyhydric alcohol, and the oil phase components are efficiently encapsulated in the polyhydric alcohol or polyhydric alcohol aqueous solution.

The polyhydric alcohol used in the present invention is a hydrophilic polyhydric alcohol containing two or more hydroxyl groups in the molecule, such as ethylene glycol, propylene glycol, 1,3-butylene gelicol, 1,4-butylene gellicol, dibrovi, runglycol, glycerin, and polyglycerin such as diglycerin, triglycerin, tetraglycerin, glucose, maltose, maltitol, sucrose,
The blending amount of fructose, xylitol, sorbitol, and maltotol is preferably 2 to 95 wt%.

The heat input polysaccharides having a carboxyl group in the molecule in the present invention may be of plant, animal, or microbial origin, such as pectic acid, alginic acid, hyaluronic acid, chondroitin, chondroitin 4-sulfate/chondroitin 6-sulfate, and fundroitin sulfate. E1 dermatan sulfate, chondroitin sulfate H5 α-heparin, ω-heparin, gum tragacanth, etc. are polysaccharides having alduronic acids such as glucuronic acid, mannuronic acid, 13' lacturonic acid, glu, uronic acid, and iduronic acid as constituent sugars.

Propylene glycol ester was obtained by the addition reaction of the carboxyl group of the poly[11] with propylene oxide. The number of moles added is not particularly limited, but about 0.5 to 2 moles is preferably used.

If propylene glycol ester is used under strongly alkaline conditions, there is a concern that it will decompose, so it is desirable to use it under acidic to neutral conditions.

The amounts used of one or more polymers made from propylene glycol esters of the carboxyl groups of natural polysaccharides that have carboxyl groups in the molecule and polyhydric alcohols that have two or more hydroxyl groups in the molecule are based on the superposition ratio. The range of 1:2 to 1000 is preferable. If the ratio of the propylene glycol ester of the natural polysaccharide to the polyhydric alcohol is 1:2 or more, it will be difficult to dissolve the polyhydric alcohol, and l: 10
If it is less than 00, emulsion stability will deteriorate.

When adding water to polyhydric alcohol and polysaccharide propylene glycol ester as necessary, use a lid for water so that the total amount does not exceed 1/2 of the weight of the polyhydric alcohol.
It is preferably 0% by weight (hereinafter, % indicates weight%) or less - The above specified amount (the following is a blank space) Oil phase components include animal and vegetable oils and fats such as beef tallow, squalane, olive oil, jojoba oil, and rice bran oil. and hydrocarbons,
Liquid paraffin, mineral oils such as petrolatum, isopropyl myristate, pentaerythritol tetra-2-ethylhexaneate, 2-heptylundene palmitate, vitamin E acetate, ester oils such as vitamin E acetate, methylphenyl silicone, dimethyl Oils commonly used in the cosmetics, pharmaceutical, food, and other industries, such as silicone oil, are used.

It is desirable that the total amount used, including polyhydric alcohol, Kolaken or its decomposition products 1 or their salts, and water as necessary, is 20-xi% or more based on the oil phase components. .

Depending on the intended use, nonionic surfactants, anionic surfactants, amphoteric surfactants, and cationic surfactants may be mixed and added. Additionally, alcohol, fatty acids, other water-soluble polymers, etc. may be added for the purpose of homogeneity stabilization, viscosity adjustment, etc.

The emulsified composition obtained here is a uniform, transparent or translucent gel or viscous liquid, so it can be used as it is, for example, in sun care jelly, beauty serum, edible jelly, medicated jelly, etc.
It can be suitably used as a lubricant in all fields such as food, cosmetics, and feed.

Second, an emulsion composition containing one or more of the above polysaccharide propylene glycol esters, a water-soluble polyhydric alcohol containing two or more hydroxyl groups in one molecule, an oil phase component, and optionally water. In addition, an oil-in-water emulsion composition further containing an aqueous phase component will be described.

The oil-in-water emulsion composition according to the present invention can be obtained by gradually adding an aqueous phase component to the emulsion composition. In this case, it goes without saying that it is preferable to perform homomixer treatment. The oil-in-water emulsion composition obtained here has extremely excellent stability.

Regarding the quantitative relationship between the emulsifying composition and the aqueous phase components, it is possible to produce emulsions in an extremely wide range of proportions, and by diluting 5 to 80 parts of the emulsifying composition with 95 to 20 parts of the aqueous phase components. Fine particles are dispersed to prepare a stable oil-in-water emulsion composition.

Water phase components include wetting agents, water-soluble vitamins, water-soluble preservatives,
Water-soluble drugs, water-soluble polymers, and other water-phase components commonly used in the cosmetics, pharmaceutical, and food industries are dissolved in water.

The oil-in-water emulsion composition obtained here is a milky white viscous or low viscosity liquid with uniform fine particles dispersed therein, so it can be used as is or used for homogeneity stabilization, viscosity adjustment or medicinal efficacy. By adding water-soluble polymers, drugs, surfactants, etc. in order to make the product have a certain amount of It can be suitably used in all fields such as food.
