Ranir is a high growth niche oral care player and the move aims to inject further investment resources to maintain future growth.
Linden, which bought up the controlling stake in the business in April 2005, says it will maintain a minority stake in the oral care player.
Ranir's recent expansion has seen it expand its sales platform to include virtually all top chain drug stores, mass merchandisers, supermarkets and discount stores in North America.
Tooth-whitening focus
The company's products include tooth-whitening wraps, trays and gels, dental floss, toothbrushes and other oral care accessories, with an emphasis on high quality.
As well as being a supplier to retailers, the company is also a turnkey manufacturing partner for global branded oral care consumer product companies.
Ranir CEO Christine Henisee, who has led the company since 2003, has helped transform the company from a small niche player into a key resource within the segment.
Growth to focus on niche areas
Kayak Holdings will purchase the controlling stake through JP Morgan Chase, although terms and the cost of the transaction were not revealed.
Ranir has built a name for itself in the fast-growing tooth whitening market in North America, which is an area that provides great potential in an otherwise largely stagnant oral care market.
Currently valued at $500m in the US, the tooth whitening market has been inundated with major launches in recent years, as well as being affected by claims that some of the ingredients used in certain products can be perilous for tooth enamel.
