Definitions
- the present invention relates to a cosmetic oil-in-water emulsion (O / W emulsion) containing hydroxypropyl starch phosphate (INCI: Hydroxypropyl Starch Phosphate) and one or more perfumes selected from the group of compounds of tertiary alcohols, acyclic terpinoic and benzopyrones, wherein the Preparation is free from carbomers and polyacrylates.
- O / W emulsion containing hydroxypropyl starch phosphate (INCI: Hydroxypropyl Starch Phosphate) and one or more perfumes selected from the group of compounds of tertiary alcohols, acyclic terpinoic and benzopyrones, wherein the Preparation is free from carbomers and polyacrylates.
- Skin care products usually creams, ointments or lotions, are mostly used to moisturize and moisturize the skin. Active ingredients are often added to them, which regenerate the skin and, for example, prevent and reduce its premature aging (e.g. the development of fine lines, wrinkles).
- cosmetics In addition to cleaning and caring for the skin, cosmetics also have an aesthetic task. They should “improve” the external appearance of the user according to the respective cultural ideas. Cosmetics thus fulfill a psychological and social function, since they increase the (optical) attractiveness of the user. Above all, this area includes “decorative" cosmetics, which change the appearance of the user with the help of dyes applied to the skin. Indirectly, however, cleaning and care products also have a positive influence, since clean, healthy skin corresponds to people's ideal of beauty.
- Perfumes are usually added to cosmetic preparations, which are intended to give the preparation a characteristic fragrance/smell. If you swap carbomers for conventional cellulose derivatives, you need more perfume to achieve the same fragrance intensity. On the other hand, it was found that the scent changes relatively quickly under the influence of light and/or higher storage temperatures.
- the object is surprisingly achieved by a cosmetic oil-in-water emulsion (O/W emulsion) containing a) hydroxypropyl starch phosphate (INCI: Hydroxypropyl Starch Phosphate), b) one or more perfumes selected from the group of compounds of tertiary alcohols, acyclic Terpinoie and benzopyrone, the preparation being free from carbomers and polyacrylates.
- O/W emulsion containing a) hydroxypropyl starch phosphate (INCI: Hydroxypropyl Starch Phosphate), b) one or more perfumes selected from the group of compounds of tertiary alcohols, acyclic Terpinoie and benzopyrone, the preparation being free from carbomers and polyacrylates.
- the object is also surprisingly achieved by a process for stabilizing the odor of cosmetic O/W emulsions containing perfumes which are free from carbomers and polyacrylates, hydroxypropyl starch phosphate (INCI: hydroxypropyl starch phosphate) being added to the preparation.
