Preferably, the sunless tanning agent is selected from the group including dihydroxyacetone, melanin, mahakanni, methyl glyoxal, erythrulose, alloxan, 2,3-dihydroxy succindialdehyde and mixtures thereof. The adjuvant is preferably a Æ -aminoalkyl hydrogen sulphate of formula (I) e.g. 2-aminoethyl hydrogen sulfate. A method of imparting a sunless tan to skin comprising the steps of applying the formulation to the skin is also outlined.
