Synthetic biopolymers are human-made copies of biopolymers obtained by abiotic chemical routes. [1] Synthetic biopolymer of different chemical nature have been obtained, including polysaccharides, [2] glycoproteins, [3] peptides and proteins, [4] [5] polyhydroxoalkanoates, [6] polyisoprenes. [7]
Natural skin care uses topical creams and lotions made of ingredients available in nature. [1] Much of the recent literature reviews plant-derived ingredients, which may include herbs, roots, flowers and essential oils, [2] [3] [4] but natural substances in skin care products include animal-derived products such as beeswax, and minerals.
Isolating a natural product from its source can be costly in terms of time and materials, and may impact the availability of the natural resource or have ecological consequences. For example, it is estimated that harvesting enough paclitaxel for a single dose of therapy would require the bark of an entire yew tree (Taxus brevifolia). [124]
However, most polymers have a hydrophilic nature and start deteriorating when exposed to moisture. Biopolymers are also being used as edible films that encapsulate foods. These films can carry things like antioxidants, enzymes, probiotics, minerals, and vitamins. The food consumed encapsulated with the biopolymer film can supply these things to ...
Bioplastics can be made from proteins from different sources. For example, wheat gluten and casein show promising properties as a raw material for different biodegradable polymers. [41] Additionally, soy protein is being considered as another source of bioplastic. Soy proteins have been used in plastic production for over one hundred years.
Disposable plastic cups made from biodegradable plastic. Biodegradable plastics are plastics that can be decomposed by the action of living organisms, usually microbes, into water, carbon dioxide, and biomass. [1] Biodegradable plastics are commonly produced with renewable raw materials, micro-organisms, petrochemicals, or combinations of all ...
Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams and the works of mound-building termites are thought of as natural. People cannot find absolutely natural environments on Earth,naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other.
