A machinery manufacturer that helped popularize Hellmann's mayonnaise plans a $3-million expansion in Suffolk County, officials said.

Chemicolloid Labs Inc. wants to purchase a 20,000- square-foot building at 75 Corporate Dr. in Hauppauge for its headquarters and factory. The company now operates from a 12,600-square-foot space at 55 Herricks Rd. in New Hyde Park.

The move from Nassau County to Suffolk County is being aided by $131,118 in tax breaks over 10 years from Suffolk's industrial development agency.

IDA executive director Anthony Manetta said this week that Chemicolloid had been wooed by other states, including North Carolina.

Suffolk wanted to keep the eight jobs on Long Island, he said, because they pay, on average, $43,750 per year. Five more positions are expected to be added by 2016.

Manetta said Chemicolloid's steel machinery, known as "The Charlotte," helped mayonnaise seller Richard Hellmann begin mass production of his sandwich and salad staple.

The recipe was devised by Hellmann's wife and debuted publicly around 1905 in the couple's deli in New York City, according to Best Foods Inc., which purchased Hellman's mayonnaise in 1932.

Besides mayonnaise, Chemicolloid equipment is used to make salad dressings, peanut butter, lubricants and greases, dyes, adhesives, lipstick and toothpaste.

The business "has great growth potential," Manetta said this week. "They are a small shop . . . and company president Anthony Pepe is incredibly motivated to grow into a larger, more global company."

Pepe did not respond to telephone and email messages requesting comment earlier this week.

An attorney for Chemicolloid confirmed Tuesday that it would move its entire operation to Hauppauge this year. The company also owns its current home in New Hyde Park.
