Abstract:
The use of plastic became popular due to its affordability, lightweight nature, and cost-efficiency in shipping. In the cosmetic industry, plastic is widely used in packaging, and as consumerism continues to rise, so does the concern over plastic waste, which has become a significant environmental issue. Biodegradable polymers, such as Polyhydroxyalkanoates (PHA) and Polylactic Acid (PLA), offer a sustainable alternative by breaking down over time through microbial or enzymatic action. This research investigates the chemical degradation of PHA and PLA, their biodegradability, and their applications in cosmetics, as well as the types of cosmetic products that are best suited for these materials. The methodology used for this research is analyzing journal articles, packaging industry data, and consumer preferences from social media. The findings provide insight into the sustainability of biodegradable polymers, their current role in cosmetic packaging, and their suitability for different product types. This research aims to inform consumers and encourage beauty companies to replace conventional plastics with biodegradable alternatives, such as PHA and PLA, which are necessary to promote more sustainable packaging solutions that reduce environmental impact.
