Pseudo-waxes are excipients that have physical properties similar to those of waxes but are not waxes in the chemical sense, i.e. esters of fatty acids with fatty alcohols. They may be mixtures of hydrocarbons and/or fatty acids and/or fatty alcohols and/or fatty acid esters and/or hydrogenated or unhydrogenated oils (triglycerides). Examples for hydrocarbons are petrolatum and paraffin.

    [0060] Skin conditioning agent may be any agent that has positive impact on skin and can be a pharmaceutical or cosmetic ingredient.

    [0067] In this example, a balm was prepared by melting of the solid components in a water bath at a temperature sufficiently high to melt all ingredients, at about 60° C.-70° C. Subsequently, the liquid ingredients were added, and the mixture was stirred to form a bulk. Any volatile ingredients were added after letting the bulk cool under stirring, but whilst the bulk was still fluid. The fluid bulk was poured into a stainless steel mould with an array of recesses of hemispheric shape. Excess bulk was scraped off. The mould filled with the bulk was let cool down at 5° C. for 20 minutes. The solidified balm hemispheres were removed from the mould by turning it upside down and placing it on a hard surface. To produce the combination product, the balm was pressed on the base element (34, 34′) and the base element was assembled with the remaining parts of the balm holder element (30, 30″) and the container which contains the formulation for nasal administration.
