Problems solved by technology

However, the formulation is highly controversial as it may cause irreversible changes in the skin pigment system
[0013] In addition, peeling (chemical and physical "peeling") is used, however peeling is often inflammatory and can lead to even worse pigmentation due to subsequent post-inflammatory hyperpigmentation Deposition (rather than reduced pigmentation)
All these common methods (which are also used to treat post-inflammatory hyperpigmentation) are characterized by important side effects

Embodiment Construction

[0050] The following examples illustrate the invention, but do not limit it. Unless stated otherwise, all expressions of amounts, parts and percentages are by weight and total or total weight of the preparation.

[0051] The use of bisulfites or disulfites (sodium bisulfite, sodium metabisulfite, sodium disulfite) in cosmetic bases such as emulsions and hydrogels allows for improved natural color and base discoloration due to storage. According to the present invention, sodium disulfite Na 2 S 2 o 5 Preferably as NaHSO 3 Exist in aqueous solution.

[0052] The parameter "discoloration" shall be defined by means of the measurement method. A commercially available "Spectro-Pen" measures three values ​​that stretch the so-called L * a * b-color space and gives brightness information and color space in that the determined values ​​are compared with each other.

[0053] Each discernible color in the color space has coordinates on 3 axes {L * 、a * , b *} color point (Farb...

Abstract

Cosmetic or dermatological preparations containing 4-n-butylresorcinol combined with one or more sulfites, especially hydrogen sulfites and / or disulfites.

Description

technical field [0001] The present invention relates to cosmetic or dermatological preparations having 4-n-butylresorcinol in combination with one or more disulfites. Background technique [0002] Pigment cells, which are responsible for skin pigmentation, are present in the lowest layer of the epidermis (basal layer), pigment-forming cells that occasionally or frequently appear next to the basal cells depending on the type of skin. [0003] Pigment cells contain chromoplasts as characteristic organelles in which pigments are formed. Primarily in the event of stimulation by UV rays, the pigmentation is intensely formed. The pigment is eventually transferred through the active layer of the epidermis (keratinocytes) to the stratum corneum (keratinocytes) and results in a more or less pronounced brown to brown-black skin color. [0004] Pigment is formed as the end product of an oxidation process in which tyrosine is converted through multiple intermediates with the assistanc...
