Definitions

• Cosmetic or pharmaceutical preparations with reduced stickiness containing glycerol esters of ⁇ -hydroxycarboxylic acids and saturated fatty acids
• the present invention relates to cosmetic or pharmaceutical preparations with a reduced feeling of stickiness, to processes for their preparation and to the use of active ingredients for reducing the feeling of stickiness of cosmetic preparations.
• Cosmetic skin care is primarily to be understood as meaning that the natural function of the skin as a barrier against environmental influences (e.g. dirt, chemicals, microorganisms) and against the loss of the body's own substances (e.g. water, natural fats, electrolytes) is strengthened or restored.
• environmental influences e.g. dirt, chemicals, microorganisms
• loss of the body's own substances e.g. water, natural fats, electrolytes
• the aim of skin care is also to compensate for the loss of fat and water in the skin caused by daily washing. This is especially important when the natural regeneration ability is insufficient.
• skin care products are intended to protect against environmental influences, especially sun and wind, and to delay skin aging.
• Medical compositions usually contain one or more drugs in effective concentration.
• cosmetic and medical use and corresponding pro products refer to the legal provisions of the Federal Republic of Germany (e.g. cosmetics regulation, food and drug law).

• Certain components of the water phase e.g. Glycerin, but also the oil phase, e.g. tocopheryl acetate, have a negative effect on the sensory properties of the preparations in higher concentrations. This often manifests itself in an increased feeling of stickiness or a feeling of greasiness when using corresponding preparations, which in individual cases may not be marketable because they are not accepted by the consumer or judged negatively.
• Another object of the present invention was to provide products with the widest possible range of applications. For example, basics for
