Kenaf (Hibiscus cannabinus) is a tropical plant recognized for its versatile uses and rapid growth. It is valued both for its ornamental beauty and its utility in various industrial applications. The plant is particularly noted for its fibrous stalks, which are used in paper production, textiles, and other materials.

Botanical Classification:

Family: Malvaceae
Genus: Hibiscus
Species: H. cannabinus
Common Names: Kenaf, Hemp Hibiscus

Plant Characteristics:

Size: Hibiscus cannabinus can grow up to 2.5 to 4 meters (8 to 13 feet) tall, with a similar spread. It has an erect, bushy growth habit.
Leaves: The leaves are palmate and deeply lobed, with a rough texture. They are typically green and can have a serrated margin.
Flowers: The flowers of Hibiscus cannabinus are relatively small, with colors ranging from pale yellow to white with a reddish center. They are less prominent compared to other Hibiscus species but still add to the plant's overall attractiveness.
Fruit: The plant produces small, dry capsules containing numerous tiny seeds. These seeds are not typically used ornamentally but are valuable for propagation.

Chemical Composition and Structure:
Hibiscus cannabinus contains several beneficial compounds:

Fibers: The plant's main feature is its fibrous stalks, which are rich in cellulose and hemicellulose. These fibers are used in various industrial applications, including paper production and textiles.
Flavonoids: Like other Hibiscus species, it may contain flavonoids such as quercetin and kaempferol, known for their antioxidant and anti-inflammatory properties.
Tannins: Present in the leaves and stalks, contributing to astringent and antimicrobial effects.
Essential Oils: Found in minor amounts, providing a subtle aroma.

Uses and Benefits:

Industrial: Hibiscus cannabinus is extensively used for its fibrous stalks, which are processed into kenaf fiber. This fiber is used in making paper, textiles, and composite materials. It is valued for its strength, durability, and eco-friendliness.
Ornamental: While primarily grown for industrial purposes, Hibiscus cannabinus can also be used ornamentally due to its attractive foliage and flowers. It can serve as a tall, bushy plant in garden settings.
Environmental: Kenaf is used in erosion control and as a green manure crop due to its rapid growth and soil improvement properties.

Applications:

Paper Production: Kenaf fiber is used to produce high-quality paper products, including newsprint and writing paper.
Textiles: The fibers are used in making textiles, including fabrics and ropes, valued for their strength and sustainability.
Composites: Kenaf fibers are used in composite materials for automotive and construction industries due to their durability and lightweight properties.
Gardening: In ornamental gardening, it can be used to create height and texture in garden beds and borders.

Environmental and Safety Considerations:

Environmental Impact: Hibiscus cannabinus is an environmentally friendly crop, as it grows quickly and can be cultivated with minimal impact. Its use in paper and textiles offers a sustainable alternative to traditional materials.
Safety: Generally considered safe for cultivation and use. The plant’s fibers and seeds do not pose significant health risks. However, as with all plants, handling should be done with care to avoid potential allergic reactions. There are no significant safety concerns associated with Hibiscus cannabinus.

INCI:


Skin conditioning agent. It is the mainstay of topical skin treatment as it has the function of restoring, increasing or improving skin tolerance to external factors, including melanocyte tolerance. The most important function of the conditioning agent is to prevent skin dehydration, but the subject is rather complex and involves emollients and humectants that can be added in the formulation.
