Abstract
Abstract A melt spinnable carrier agent such as sugar is combined with a cosmetic then converted into fiber form by melt spinning with "cotton candy" fabricating equipment. The as-spun product is converted to compacted individual dosage units. Examples are presented for topical application. All applications utilize the extraordinarily rapid entry of the fiber form mass into solution upon contact with a solvent. When lactose is used it absorbs moisture from the air which is then either transferred to the hair or skin to maintain the moisture content of the latter or it prevents the hair or skin from drying out.
