PHA, also known as polyhydroxy acid, is a series of natural high molecular polymers synthesized by microorganisms and can be biodegraded under aerobic and anaerobic conditions.

 Polyhydroxyalkanoate has many advantages that make it a candidate for sustainable and environmentally friendly alternative materials:

1. Biodegradability: PHA can be degraded by microbial enzymes present in nature and eventually decomposed into carbon dioxide and water. This property allows PHA to be biodegraded after its service life, reducing its impact on the environment.
2. Renewability: PHA is produced by microorganisms through biosynthetic processes such as fermentation, and can use renewable resources as raw materials, such as vegetable oils, sugars and waste.
3. Physical properties: PHA has similar physical properties to traditional plastics, including strength, toughness and heat resistance. It can be used to prepare various types of products, such as films, fibers, injection molded parts, etc.
4. Wide application: PHA has a wide range of application potential in many fields, including packaging materials, medical supplies, agricultural films, textiles, biomedicine, etc.
5. Reduce dependence on fossil fuels: The production of PHA does not rely on limited resources such as oil. By utilizing renewable resources, the demand for fossil fuels can be reduced.

Application of PHA

1.Packaging field

PHA has the potential to replace traditional plastic packaging due to its excellent degradability and air barrier properties. PHA has good processing performance and surface properties, and is non-toxic and harmless, and can be used for food contact packaging.

2.Medical field

PHA is often used in the medical field to make surgical sutures, staples, bone substitutes, vascular substitutes, drug sustained-release carriers, medical gloves, dressing materials, hemostatic plugs, and medical films. Because of its good biodegradability, it can be used in agriculture to make long-lasting pesticides and biodegradable carriers for fertilizers.

PHA has a broad application background in biodegradable packaging materials, tissue engineering materials, sustained-release materials, electrical materials, and medical materials. The biggest difficulty facing the application of PHA is the high cost, so PHA is currently also used in the cosmetics field.

Polyhydroxyalkanoate can be used in a variety of products and in a variety of ways. PHA can be added to any type of product – liquid exfoliant, toner, mask or moisturizer, giving the skin exfoliating, skin smoothing, moisturizing and anti-aging effects, but that’s not all, PHA can be combined with other ingredients or dermatological procedures to provide additional benefits to the treatment. PHA can be combined with retinoids when treating acne or photoaging. PHA can be combined with hydroquinone to improve skin pigmentation and aging. PHA can also be used after cosmetic procedures such as laser and microdermabrasion, but a dermatologist should be consulted.

PHA is gentler on the skin because their molecular size is larger. You may wonder why this is? Because the large size of PHA prevents them from penetrating deep into the skin, but gently washes away any dirt on the surface of the skin.
