1 Claim.

This invention relates to a method of making a shaving aid and also to a shaving aid made in accordance with this method. F

Tale powder and similar substances for promoting sliding make shaving easier, particularly shaving by means of electric dry-shaving apparatus, since this powder removes sweat from the skin and thereby increases the ease of sliding. Talc or similar powders are however impractical in service, since their use entails an undesirable formation of dust.

The hitherto known methods of shaping talc, i. e. of pressing it into bars or blocks, are unsatisfactory since they all posses the drawback of giving off too much talc powder when used and of greatly dirtying the clothes in consequence of the poor adherence of the talc powder to the skin and the hairs of the beard.

The present invention endeavours to remove this drawback.

According to the method in this invention at least one fatty substance, solid at ordinary ambient temperature, is melted and intimately mixed with a substance to promote sliding, for instance talc powder, which is heated to at least the melting temperature of the fatty substance; the mixture is then pressed into shaped pieces.

The shaving aid obtained in accordance with this method consists of a shaped piece which contains at least one substance to promote sliding, intimately mixed and physically combined with fat.

The mixture is homogeneous and contains for instance, up to 20% by weight of fat of mineral, vegetable, animal or chemical origin, with respect to the weight of the sliding-promoting substance, for instance talc or a neutral soap.

To the mixture, one or more antiseptics, colouring matters, and scents may be added.

A particularly suitable fat is, for instance, spermaceti. As means to promote sliding tale is preferably used, but other substances with similar physical properties could be also adopted.

As colouring matter ochre may be added and with electric razors, which comprises melting a quantity of spermaceti wax, preheating at least five times that amount by weight of talcum powder to a temperature substantially equal to that of the molten wax, and adding the preheated talc to the molten wax under agitation until a homogenous mixture is formed, and pressing said mixture into shaped pieces.
