If you've washed, shaved, and groomed, then you've probably shared a chemical experience with the folks at International Specialty Products (ISP). The company, also called ISP Chemco, makes about 400 types of specialty chemicals, including food and pharmaceutical ingredients, personal care, and fine chemicals, industrial chemicals (like butanediol for fibers and plastics), and minerals products. ISP also makes waterproofing agents, moisturizers, and preservatives for personal care products such as sunscreen and hair care products. Chairman Samuel Heyman owns ISP; after watching the company's stock dive in 2002, Heyman took ISP private.
