rather than a specified budget. In 1951, Bishop became the first woman to appear solo on the cover of Business Week. Bishop's innovative use of bromo acids would set in motion what would be known as the "lipstick wars." with competitors such as Revlon making their own versions of Bishop's formula in vying for dominance of the cosmetics market. The advent of the "no smear" lipstick would prove to be a success for Bishop, as her debut line would not only sell out on the first day, but end up taking over 25% of the American lipstick market. In four years, sales soared to $10 million. Bishop lost control of the company in 1954 in a proxy fight with majority stockholders, led by Spector. The case was settled on February 17, 1954, with the company (of which Spector was chairman and holder of 92% of the stock) purchasing Bishop's 8% of company stock, with the stipulation that she refrain from selling products under her own name and that she make clear in future ventures that she was no longer associated with Hazel Bishop, Inc.[4] After leaving the company, she became a consultant to the National Association of Leather Glove Manufacturers and developed "Leather Lav," a leather glove cleaner. She then founded H.B. Laboratories, Inc. to produce additional leather products. Bishop also developed a foot care product, marketed by H.G.B.
