Extraction selectivity of whole wool wax from raw wool by using ethanol-modified carbon dioxide at constant pressure ( bar) and temperature (60°C) was studied. A kinetic study was carried out to optimize the percentage of ethanol and the extraction :// Abstract.
Since the inception of humankind, people have relied heavily on natural products for food and living. Through several trials and errors, they discovered that few plants are good as food, whereas some are poisonous, and that some produce physiological changes such as increased perspiration, hallucination, relief from pain, induction of bowel movement, and :// The inhibition response to extracts was not uniform across members of the same bacterial genus.

Wool is one of the animal fibres obtained from sheep and some other animals. Animal fibres are the fibres that are naturally obtained from animals. Some animals that live in cold places generally have a thick coat of hair on their body.

These antioxidants can be degraded during the storage of grape stem extracts for long periods of time. The aim of this work was to analyze the stability of Mazuelo stem extracts during storage at 25 and 40 °C, in two different light conditions (amber and transparent vials). The stability of the antioxidants was studied after 2, 4 Dyeing ability: Wool fiber could be dyed by basic dye, direct dye and acid dye.
It is noted that; all the wool fiber is not same in characteristics. It varies depending on the wool’s country of origin and sheep type. So, choose your wool fiber after confirming about the physical and chemical properties of wool The main commercial applications of extracts from natural sources discussed here comprise their use as colorants, functional food, nutraceuticals, flavors and fragrances, preserving agents, and edible/non‐edible oils and fats applied to cosmetic, pharmaceutical and food :// Natural products are sought after by the food, pharmaceutical and cosmetics industries, and research continues into their potential for new applications.
