JPS61225109A - Caramel-containing composition - Google Patents

Abstract

PURPOSE:To provide the titled composition exhibiting excellent storage stability against heat and light even in the case of compounding to a base such as cosmetic, medicinal drug, food, etc., by compounding cysteine in combination with caramel. CONSTITUTION:The objective composition contains caramel and cysteine at a weight ratio of 10:1-1:100, and if necessary contains additional components used generally in the field of cosmetic and food, such as surfactant, oil, UV- absorber, preservative, organic solvent, drug, perfumery, etc. Although caramel has poor light resistance and is decomposed and discolored easily by heat and light when compounded to cosmetic, medicine, food, etc., however, a composition having excellent storage stability can be produced by the combined use of caramel with cysteine.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a composition containing cysteine and caramel, which has excellent storage stability, and which is useful in the fields of cosmetics, pharmaceuticals, foods, dyes, etc. It is an object of the present invention to provide the above composition.

[Prior Art] Caramel is an amorphous substance in which saccharose melts at 160°C to become candy-like and turns brown at 200°C. It dissolves in water and exhibits a yellow-brown to brown color.

Saccharose is a class II substance and is also called sucrose or sucrose, and its structure is α-D-glucopyranosyl-β-D-
It is a fructofuranoside and is industrially produced from sugar beet, sugar cane, sugar maple, etc., which exists widely in the plant kingdom, and is also called beet sugar.

The structure of caramel obtained from saccharose has not yet been confirmed in detail, and it exhibits extremely complex reactions depending on the conditions of the recipient. It is classified by raw material and production into regular caramel, glucose caramel, and sugar caramel.

[Problems to be Solved by the Invention] These caramels have low light resistance, and when incorporated into cosmetics, medicines, and foods, they have the disadvantage of being easily decomposed and discolored by temperature and light.

Several attempts have been made to compensate for the above-mentioned drawbacks. For example, 2,2'-4,4'-tetrahydroxybenzophenone, 2-hydroxy-4-methoxyhensiphenone sulfate, urocanic acid, 2-ethylhexyl-p-
Attempts have been made to maintain stability against temperature and light by using a so-called ultraviolet absorber such as dimethylaminobenzoate, but the effects are still far from satisfactory.

In view of the above circumstances, the present inventors have worked diligently to obtain a caramel composition that has excellent storage stability against temperature and light, and that also satisfies the above stability when incorporated into bases for cosmetics, pharmaceuticals, foods, etc. As a result of repeated research, the inventors have discovered that the above object can be achieved by using cysteine in combination with caramel, and have completed the present invention.

Means for Solving Problem L] That is, the present invention is a composition characterized by containing cysteine and caramel.

In the present invention, the weight ratio of caramel and cysteine is preferably 10=1 to 1:100.

In addition to the above-mentioned essential components, the composition of the present invention may optionally include nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, oils, waxes, ultraviolet absorbers, and preservatives. It is also possible to add ingredients commonly used in the fields of pharmaceuticals, cosmetics, foods, etc., such as agents, antioxidants, organic solvents, drugs, water-soluble polymers, powders, pigments, fragrances, and water.

[Effects of the Invention] Next, the present invention will be explained in further detail with reference to experimental examples and examples.

Experimental Example 1 A composition with the following formulation was manufactured, and the color tone of the product stored in the dark at 50'C for one month and the product irradiated with a xenon lamp for 30 hours (temperature 50'C) was compared with the corresponding product stored in the dark at 0°C. did.
