Assinoun 

a hybridized "word" composed of two existing nouns created by a marketing guru to entice consumers to believe a new science based product has become available. These are easily identified by the hyphen and of course the Trademarking.

New assinouns: Stabili-Track, Acti-lift Technology, Vita-niacin Complex, Kera-Fibre Complex. The advertisers want me to think of four wheel drive, laundry detergent, face cream and mascarra when I hear them.
