Preparations for covering undamaged and/or damaged areas of human or animal skin

DETAILED DESCRIPTION We claim: 1.
A method for dressing wounds to the skin wherein the wound is allowed to breathe, the exudate is absorbed, and the granulation process is accelerated, comprising applying to said wound a vulnery powder comprising as a carrier material a solid powdered oligomeric ester of lactic acid and/or gylcolic acid, or a dermatologically compatible derivative thereof, wherein the oligomeric ester has a degree of oligomerization of up to about 100.
2.
The method of claim 1 wherein the wound is open and the vulnery powder forms an artificial scab on the wound in conjunction with fluid from the wound.
3.
A method for applying a disinfectant composition to cow udders comprising applying to the cow udders a thinly liquid to paste-like composition containing the disinfectant and as a carrier material an oligomeric ester of lactic acid and/or glycolic acid or a dermatologically compatible derivative thereof to form a non-porous film on the cow udders, and leaving the composition in contact with the cow udders until it is resorbed through the cow udders, and wherein the oligomeric ester or its derivative has an average degree of oligomerization of from 2 to about 50 and the degree of oligomerization is selected to obtain a predetermined time period measured in hours in which the oligomeric ester or its derivative remains in contact with the cow udders before resorption.
4.
The method of claim 3 wherein the composition is resorbed through the cow udders in a period of from about 10 to about 12 hours from the time of application.
5.
A vulnery powder comprising as carrier material a solid oligomeric ester of lactic acid and/or glycolic acid, or a dermatologically compatible derivative thereof, wherein the oligomeric ester has a degree of oligomerization of up to about 100.
6.
The vulnery powder of claim 5 wherein the carrier material is a dermatologically-compatible derivative which is an ester of a monofunctional or polyfunctional alcohol.
7.
The vulnery powder of claim 5 wherein the carrier material is a dermatologically-compatible derivative which is an ester of a monofunctional or polyfunctional carboxylic acid
