Ceiba Pentandra Fruit Fiber — INCI reference

What it is

Ceiba Pentandra Fruit Fiber consists of lightweight, hollow tubular fibers harvested from the seed pods of the kapok tree (Ceiba pentandra, family Malvaceae). Each fiber is a thin-walled tube approximately 15–35 µm in diameter and 10–35 mm in length, containing up to 80% air by volume. The fiber is naturally hydrophobic and has a notable oil-absorbent capacity. In cosmetic formulations, it functions primarily as a bulking agent, contributing body, texture, and a lightweight feel to products such as mascaras, powders, and conditioning products. The fiber is biodegradable and sourced from a renewably grown tropical tree. Its hollow, low-density structure makes it one of the lightest natural fibers available, approximately one-eighth the density of cotton.

Safety & warnings

Kapok fibers are not known to cause allergic reactions and are generally considered comfortable on skin. The material is biodegradable with no GHS hazard classifications identified. No specific allergen, irritant, or comedogenic concerns are documented in cosmetic-use concentrations. Fine airborne fiber dust from dry powder forms may be a general inhalation consideration during manufacturing, as with any fine particulate.

Origin & sourcing

Derived from the fruit pods of Ceiba pentandra (kapok tree), a tropical tree native to Central America, the Caribbean, northern South America, and parts of West Africa. The fluffy fiber surrounds seeds inside large woody pods. After harvest, pods are opened and fiber is separated, dried, and ground into powder for cosmetic use. Major producing regions include Indonesia, Thailand, the Philippines, Sri Lanka, Nigeria, and Ecuador.

History

Kapok fiber has been used commercially since at least the 19th century, primarily for stuffing life jackets, pillows, and mattresses due to its buoyancy and water resistance. It was a critical material for aviation and maritime safety equipment before World War II. Commercial kapok production peaked mid-20th century before synthetic fibers largely displaced it in flotation and insulation applications. In cosmetics, it appears in the EU CosIng database as a registered ingredient with bulking agent function.

Questions everyone asks

What is Ceiba Pentandra Fruit Fiber and where does it come from?

It is the natural fiber found inside the seed pods of the kapok tree (Ceiba pentandra), a tall tropical tree native to Central America, the Caribbean, and parts of Africa and Asia. The fluffy fibers are harvested, dried, and ground into powder for use in cosmetic formulations.

What does Ceiba Pentandra Fruit Fiber do in cosmetics?

It primarily functions as a bulking agent, adding body, volume, and a lightweight texture to products like mascaras, powders, and hair conditioners. Its hollow, low-density fiber structure contributes a soft, airy feel to formulations.

Is Ceiba Pentandra Fruit Fiber safe for skin?

Kapok fiber is not known to cause allergic reactions and carries no GHS hazard classifications for cosmetic use. It is biodegradable and has a long history of use in products that contact skin and clothing.

Is kapok fiber sustainable?

Kapok trees grow in tropical regions without requiring intensive agricultural inputs, and the fiber is naturally biodegradable. Compared to synthetic fibers, kapok has a lower environmental footprint, making it a relatively sustainable choice in cosmetic formulations.
