Embodiment Construction

[0148] Comparative experiments and examples

[0149] The following examples are intended to illustrate the invention without limiting it. All amounts, ratios and percentages are by weight and total or total weight of the formulation unless otherwise specified.

[0150]The following table lists exemplary formulation examples 1 to 9, of which only illustrative formulation examples 4 to 7 disclose O / W emulsions according to the present invention. Other example formulations are not in accordance with the invention. A comparison of O / W emulsions according to the invention and O / W emulsions not according to the invention shows that the O / W emulsions according to the invention do not exhibit phase separation and are therefore significantly more stable at elevated temperatures.

[0151] O / W emulsions were prepared by heating phases A and C to 75°C until all components were dissolved. The phases are then mixed. The mixture was homogenized and cooled to room temperature with stirrin...

Abstract

The invention relates to an acrylate-free cosmetic O / W emulsion containing at least one polyglycerol ester, hydroxypropyl starch phosphate, and glycerol monostearate and / or sorbitan monostearate.

Description

Background technique [0001] Cosmetics are often used not only to make people look beautiful and attractive, but their effects play a decisive role in enhancing people's self-worth and well-being. Therefore, various cosmetics are used for daily cleaning and care of human skin. [0002] Skin care products are usually made from lotions. Emulsion generally refers to a heterogeneous system consisting of two liquids that are immiscible or only partially miscible with each other, usually called phases, and in which one of the two liquids forms in very fine droplets form dispersed in another liquid. When visually inspected, the emulsion appeared homogeneous. [0003] If the two liquids are water and oil, and the oil droplets are finely distributed in the water, then it is an oil-in-water emulsion (O / W emulsion, eg milk). The essential properties of O / W emulsions are imparted by water. Water-in-oil emulsions (W / O emulsions, such as butter) involve the opposite principle, where the...
