LONDON, July 29 (Reuters) - Consumer goods maker Reckitt Benckiser has ramped up its efforts to sell items such as condoms and vitamins online, aiming to capture new revenue streams as traditional markets get more competitive.

Reckitt's own Durex condom website in China is already its single largest customer in the world's fastest-growing e-commerce market, doubling the number of unique visitors over the last year to over 20 million. It expects that to double again, as consumers lap up its sexual health products, which can be personalized and delivered discreetly.

As part of its drive, the group has established a new global "e-business unit" that Chief Executive Rakesh Kapoor says will help it deal better with customers like Amazon.com, be present in marketplaces like those offered by Alibaba and probe new areas such as cross-border e-commerce and direct-selling websites.

"This is a material opportunity that we want to be in the front of the pack on," Kapoor said on Friday. "Although it seems like we've come a long, long way ... we've only just started. This train is going to run faster and faster."

Reckitt expects e-commerce to generate half its Chinese revenue by 2020, up from 25 percent last year and 35 percent by the end of this year.

On Friday, Reckitt's shares fell after it damped its outlook due to a near complete loss of business in South Korea following a product safety scandal.

The British company is one of several manufacturers exploring new ways to sell online as they struggle to secure shelf space amid the rise of discount supermarket chains like Aldi and Lidl, which stock their own brands, and smaller stores that stock more independent brands.

So far, most of them have focused on selling through websites of "e-tailers" or traditional retailers, but Reckitt and peers including Nestle, Diageo and Unilever are experimenting with other models such as delivery on demand and subscriptions with automatic replenishment.

The world's online shoppers spent over $87 billion on grocery items like food, drink, beauty and personal care items in 2015, according to Euromonitor International. That represents about 9 percent of the total online spend.

Because such products can be perishable, cheap or needed immediately, they are generally less suited for online buying than goods like appliances, fashion and media. But habits are changing.
