Neem Oil

Neem Oil is a natural vegetable oil extracted from the seeds of the neem tree. It is widely known for its traditional applications in agriculture, skincare, haircare, cosmetics and personal care products.

Neem Oil contains naturally occurring fatty acids and bioactive compounds, including azadirachtin, depending on the extraction and processing method. It is commonly used in agricultural formulations, soaps, shampoos, creams and other specialty products.

Because of its versatile properties, Neem Oil is an important plant-based ingredient for agricultural, cosmetic and industrial applications.

What Is Neem Oil?

Neem Oil is a fixed vegetable oil obtained from the seeds and kernels of the neem tree, botanically known as Azadirachta indica. The tree is native to the Indian subcontinent and is widely cultivated in tropical and subtropical regions.

The oil is generally yellowish to dark brown in colour, depending on the seed quality, extraction method and refining process. It has a strong, characteristic odour.

Neem Oil is commercially available in cold-pressed, filtered and refined grades. Its composition and active compound content may vary according to the manufacturing process.

Extraction Process of Neem Oil

Neem Oil is generally produced by extracting oil from mature neem seeds and kernels.

1. Seed Collection: Mature neem fruits are collected, and the seeds are separated.
