- or a physiologically compatible salt thereof, or a stereoisomeric form thereof,
- wherein
- R1 is H or alkyl,
- R2 is H, COOH, COO-alkyl or CO—NH—R5,
- R3 and R4 are in each case independently of one another H or OH,
- n is 1, 2 or 3,
- alkyl is an alkyl radical having 1 to 4 carbon atoms, and
- R5 is H, alkyl, or an amino acid radical, dipeptide radical or tripeptide radical and
- b) thereafter continuing to administer the formulation to protect the skin from high sodium dodecyl sulfate concentration.
