Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a liquid skin cleansing composition in the form of an emulsion that is extremely skin-friendly and contains a large amount of lotion ingredients.

BACKGROUND OF THE INVENTION The present invention relates to a liquid skin cleanser that is very gentle on the skin. More specifically, the present invention relates to a skin cleansing agent in the form of an emulsion that is neutral and has well-balanced detergent and lotion components. Most soaps are basic and can be very rough on the skin, but the materials of the present invention are essentially neutral. As with most detergents, especially detergents that do not contain emollient lotions, many skin cleanser materials foam excessively.

The compositions of the invention are balanced and do not produce excessive suds, which allows them to be washed off quickly. Furthermore, while many conventional skin cleansing materials - as in the case of on-board detergents - induce or cause the skin to become completely de-oiled, the compositions of the present invention dry out the skin. Or wash away the surface and crevices of the skin without making it rough. Furthermore, instead of the rather poor quality detergents commonly used in conventional formulations, which are considered or even considered to be skin-friendly skin cleansing ingredients, The ingredients of the invention are essentially pH-neutral, using a skin-friendly detergent containing a suitable emollient lotion in an appropriate amount that provides a desirable balance between cleansing and skin softening effects. ing. This makes the lotion emollient without damaging the skin, does not over-foam, remove oil from the skin, does not dry out the skin, and achieves the desired balance between cleansing and emollient effects. By using a skin-friendly detergent containing a skin-friendly detergent, it is possible to effectively and quickly clean the surface of the skin, which has been stripped of dryness and oil, leaving it with a very soft and pleasant feeling.

Prior Art The prior art is well summarized in U.S. Pat. Nowhere in the prior art, and nowhere else known to the inventors, are there any particular requirements or requirements for or relating to the balanced, neutral, liquid detergent and lotion emulsion compositions of the present invention. I have not found any descriptions or suggestions about the ingredients or the very good results that can be achieved by using them.

(Objective of the present invention) The object of the present invention is to obtain excellent results in terms of a cleaning effect, a skin softening effect, no excessive foaming, and moderately quick washing. It also cleans without drying or removing oil from the skin, and contains a considerable amount of emollient lotion, thereby having an excellent effect between cleaning effect and emollient effect. It is an object of the present invention to produce a more satisfying liquid skin-friendly skin cleansing composition that is pleasant to use, leaves a pleasant, soft, and highly satisfying skin feel.

Another object of the present invention is to contain a particular pH that is essentially neutral, to be essentially an emulsion, and to provide a range of lotion ingredients to cleaning agent ingredients based on the solids content of the composition. It is an object of the present invention to provide such a component, and the use thereof to achieve the highly desirable characteristics of the component of the present invention.
