(57) @ An applicator for applying a flowable depilatory chemical composition to the skin
comprises a reservoir (10) charged with the composition, an applicator head (12) fastened
to the reservoir having a flow passage for the composition leading from the reservoir
to a mouth, and a generally cylindrical applicator roller (15) having an indented
surface and journalled for rotation in the mouth. The reservoir (10) is removably
connected to the applicator head (12) by a threaded neck (11) whose distal extremity
is provided with a deformable circumferential flange (20) and the applicator head
(12) has a bore (21) having a threaded portion that engages the neck (11) and that
leads to a convergent portion (22) onto which the flange (20) seats as the applicator
head (12) is screwed into position. The reservoir is charged with a flowable depilatory
composition comprising up to 10% w/w of a sulphur-containing depilatory material,
0.5-30% w/w of an emulsifying wax to give an oils-in-water cream, 0.1-5% w/w of an
inert cellulosic thickener that disperses in the aqueous phase and sufficient alkali
to give a pH of 9.0-12.5 and also glucoheptanoic acid or a salt thereof and N hydroxyethyl
ethylene diamine triacetic acid or a salt thereof.
