"Cosmetic detergent preparation with moisturizing properties"

The invention relates to a cosmetic cleaning agent preparation With moisturizing properties based on a liquid, anhydrous surfactant mixture and microencapsulated Oils.

It is already known to use detergents for body cleansing, such as foam baths or shampoos, to add oil components for the purpose of re-oiling. Be there obtain stable emulsions in which the oily constituents are so strongly solubilized by the surfactants; that the moisturizing effect is only very weak. A good moisturizing effect is, however, with foam baths and shampoos are desirable in view of the strong skin-degreasing effect of the surfactants contained therein. Enlarged on the other hand, the proportion of oil is so high that a moisturizing effect occurs, the foam becomes des Detergent pressed to such an extent that it can no longer be used as a foam bath or shampoo can address.

It is also already known to use detergent bath preparations with moisturizing properties that contain a micro-encapsulated oil. Make these preparations represent a free-flowing granulate with a free moisture content of less than 5 percent by weight. However, such products require special precautionary measures during processing, packaging and storage

to exclude the effect of moisture. Even small amounts of moisture can cause caking the granules' and microcapsules, the free-flowing state of the preparation are adversely affected. In addition, powdered bath preparations are less pleasant to use and are also less appealing to consumers.

There are also pasty, water-free shampoos with microencapsulated oils. Such mixtures are, however, for use as Foam bath preparations are not suitable as they spread and dissolve too slowly in the bathtub to achieve a satisfactory level To cause foam development. There was therefore a need for a liquid detergent preparation especially after a bubble bath preparation, which when used in the diluted form has a good Foam develops, brings about a satisfactory re-oiling of the skin and hair and that quickly distributes and dissolves in the water.

It has now been found that a liquid detergent preparation in particular bubble bath preparation with a content of 90-10 percent by weight, preferably 75-25 percent by weight, of a liquid anhydrous surfactant mixture A from the components

Dissolve over a period of about; 50 minutes, whereby preferably the majority of the oil components are released within 5-15 minutes.

The microencapsulation of the moisturizing oil component can for example, from a suspension of the oils in an aqueous solution of gelatin and gum arabic. At an elevated temperature of 40-50 ° C., the pH of the solution is adjusted with stirring so that a Forms coacervate, which encapsulates the suspended oil droplets when cooled slowly. The size of the capsules can be determined by the weight ratio of the oil component to the wall material and the stirring speed The cooling is continued to below 10 C with constant stirring. A hardening of the Microcapsules are optionally available through the addition of aldehydes such as formaldehyde, acetaldehyde or glutaraldehyde possible. After appropriate cooling, the microcapsules will freeze from the remaining solution Separated by filtration and then dried. The drying can advantageously initially by a Gradual washing with solvents, the miscibility of which with VJasser decreases. The distance the last highly volatile solvent can be carried out under reduced pressure or in a stream of air.

It is of course possible to use the Detergent preparations the cosmetic additives commonly used for bath foams and shampoos, such as fragrances, Antioxidants, deodorants, germicides, anti-dandruff agents, protein hydrolysates, herbal extracts, salts, Dyes and the like. This enables the cleaning agent preparations according to the invention created bubble baths and shampoos alongside

the cleansing and moisturizing effect can be given further nourishing properties. The perfume additive expediently takes place both in the surfactant component A and in the microencapsulated oil component B, in order to obtain a scent effect right from the start, which is constantly supplemented in the course of cleaning. Through this Encapsulation of the same or a different perfume with the oil component than is contained in the surfactant mixture, the scent or the scent tip can be maintained over the entire duration of the bath.

The wall material of the microencapsulated oils, which must be resistant to the anhydrous oils and the anhydrous surfactant component, on the other hand must dissolve easily in water, can for example consist of gelatin, gelatin gum arabic, gelatin alginate, succinated gelatin and other hydrolyzed protein materials. This waiid material forms about 10% by weight of the microencapsulated oil component B. The particle size of the microencapsulated oil component can vary widely depending on the manufacturing conditions. The diameter of the microcapsules will vary between the values of 5 to 2.00OjU. move.

It is also advantageous to use either the surfactant mixture A or the micro-encapsulated component B or to color both components differently. This not only makes the cleaning agent concentrates an interesting one and pleasing appearance, rather the consumer is able to see himself or herself by visual inspection of the To convince the presence of the nourishing oil components.

The cleaning agent preparations according to the invention can be produced by simply mixing the constituents of the tens r.dgemis ehe s A and the microencapsulated

hydrolysates in amounts of 1-5 percent by weight , anti-dandruff agents in amounts of approx. 1 percent by weight, based on the total product in the case of shampoos. With the exception of the antioxidants, all of the additives mentioned are advantageously incorporated into the surfactant component. Furthermore, the surfactant component or the encapsulated oil component or both components can be colored by adding suitable dyes with appropriate solubilities.

The advantage that can be achieved with the cleaning agent preparations according to the invention is that they are more powerful Foam development has a good cleaning effect, but at the same time a particularly good lipid replenishing capacity own. Due to the thin liquid constitution of the preparation, it is distributed evenly in the water, the Surfactant content. immediately dissolves and causes an extraordinarily strong foam development. The microencapsulated Oils, on the other hand, are only released slowly so that they cannot hinder the development of foam. In contrast to egg component foam bath preparations, the oils are not emulsified or emulsified to any significant extent. solubilized so that the desired refatting can develop fully after the cleaning phase of the bath. Another advantage of the cleaning agent preparations according to the invention is their significantly better cold resistance compared to water-based formulations.
