Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gel-like or cream-like composition, and more specifically, it can be used as a raw material for products such as pharmaceuticals, cosmetics, deodorants, etc., and is stable against temperature changes. It relates to a gel or cream composition.

Gel-like or cream-like as used herein means that it has no fluidity within the operating temperature range, and the distinction between gel-like and cream-like is that transparent ones are gel-like and opaque ones are cream-like. Traditionally, there have been many products that have a gel-like or cream-like appearance, such as ointments, pharmaceutical creams, cosmetic creams,
It is used in a variety of fields, including hair conditioners, shoe creams, floor waxes, car waxes, deodorants, and fragrances.
These are composed of substances appropriately selected from oils, emulsifiers, solubilizers, gelling agents, etc., water, and medicinal ingredients, colorants, fragrances, etc. added as necessary.
However, these mixtures have the disadvantage that they undergo large thermal changes and increase their fluidity at high temperatures, causing them to flow out of the container, or breaking the emulsion and separating fine particles and water, resulting in a significant decrease in commercial value. there were. Furthermore, there have been various problems such as solidification at low temperatures, making it impossible to remove the emulsion from the container during use, and the emulsion being destroyed and solid matter precipitated. Conventional mixtures are often stable in the range of 5 to 40 q○, and although they pose no particular problem under normal usage conditions, they may be used in conditions with more rapid temperature changes, such as outdoors, in baths, in the kitchen, in heaters or air conditioners. When used near a container, the above-mentioned problem occurs. The present inventors worked to develop a gel-like or cream-like composition that is stable against temperature changes, and as a result of intensive studies, they arrived at the present invention.

That is, in the present invention, the following component A is contained in an amount of 10 to 4% by weight,
This is a gel or cream composition characterized by containing 2 to 3% by weight of component B below and 40 to 85% by weight of water.

Examples of fats and oils having hydroxyl groups include castor oil and hydrogenated castor oil.

In the composition of the present invention, the wind component is a component that tends to stabilize the gel-like or cream-like composition at high temperatures.

Gel-like or cream-like compositions can be obtained using compounds outside the defined range, but they are unstable at high temperatures. [
Component B is a compound that has the tendency to provide stability at low temperatures, and a wide range of compounds can be used, but it must be water-soluble or water-dispersible, and 35 to 9% by weight of oxyethylene groups must be present. is necessary. However, the presence of component (■) does not necessarily mean that the product is stable at high temperatures, and the presence of component (B) does not necessarily mean that it is stable at low temperatures.
The composition of the present invention has the two components (B) and water as essential components, but may also contain medicinal ingredients, colorants, fragrances, etc., as well as waxes such as paraffin, and gelatinized materials such as carrageenan and gelatin. Other ingredients can also be added, such as agents, organic solvents such as ethanol and isopropanol.

The composition of the present invention can be easily obtained by flooding the components other than water to about 80 qo to uniformly dissolve them, and then gradually adding about 80 qo of water.

Next, the present invention will be explained by examples. Example First, a manufacturing example of the composition of the present invention will be shown.

Composition side. Production of general formula 1 [1'' where a + c = 200, b = 65 A compound (component A) 15 and polyoxyethylene (
40 mol) oxypropylene (30 mol) and stearyl ether (component B>20 mol) were added to the mixture at 70 pm and stirred for 1 hour to uniformly dissolve.

Next, add 60 portions of 70 qo of water and 5 portions of ethanol,
After stirring at 7,000° C. for 2 hours in a sealed state, the mixture was poured into a container and cooled to 20° C. to obtain a gel-like composition. This gel-like composition spreads very well and gives a moist feeling, so it is suitable as a hair styling agent. In addition, by adding a fragrance and a coloring agent, it can be used as a transparent fragrance or deodorant. Composition ship.
