Abstract: This technology relates to a method of producing light color lecithin from a lecithin-containing oil, such as crude vegetable oil. The method comprises heating the oil to a suitable temperature, contacting the oil with a peroxide solution, separating the lecithin precipitate from the oil and drying the lecithin. In a specific embodiment, the lecithin produced by the process is corn lecithin.

Abstract: An erasable product such as an erasable and rewritable label or an erasable sign comprises a base layer and a transparent or translucent upper sheet over the base layer which provides a smooth and wrinkle-free top surface to the product. The upper sheet and base layer are releasably adhesive together under pressure applied manually on the upper sheet such as writing pressure with a blunt stylus, to cause the upper sheet and the base layer to adhere in the localized region of pressure to display the writing in the case of a label. The upper sheet can be moved sufficiently to separate it from the base layer when a user's finger or thumb is wiped across the top surface of the upper sheet. The upper sheet also extends over a wipe-start region where the upper sheet and the base layer are not adhesive together, over which wipe-start region a user's finger or thumb may be placed from which to begin the movement to separate the upper sheet from the base layer.

Abstract: An erasable product such as an erasable and rewritable label or an erasable sign comprises a base layer (2) and a transparent or translucent upper sheet (3) over the base layer which provides a smooth and wrinkle-free top surface to the product. The upper sheet and base layer are releasably adhesive together under pressure applied manually on the upper sheet such as writing pressure with a blunt stylus, to cause the upper sheet and the base layer to adhere in the localized region of pressure to display the writing in the case of a label. The upper sheet can be, moved sufficiently to separate it from the base layer when a user's finger or thumb is wiped across the top surface of the upper sheet. The upper sheet also extends over a wipe-start region (2a) where the upper sheet and the base layer are not adhesive together, over which wipe-start region a user's finger or thumb may be placed from which to begin said movement to separate the upper sheet from the base layer.

Abstract: An erasable product such as a rewritable label, sign or the like includes a base layer and an upper sheet extending over the base layer. The upper sheet and the base layer are releasably adhesive together under pressure manually applied on the upper sheet to cause the base layer and upper sheet to adhere in a localized region of pressure in order to display writing, an indicia, or the like. A wipe-start region is provided where the base layer and the upper sheet are not adhesive together and in which a user may place a finger or thumb to wipe across the top surface of the upper sheet in order to separate the upper sheet from the base layer and erase the indicia.
