Lipsticks: Formulation, Production & Characterisation – A Review

The history, formulations, and production process of lipsticks are the subjects of a review article titled "Lipsticks History, Formulations, and Production: A Narrative Review." The article, which was published in the Journal of Cosmetics, is written by a team of researchers from universities in Malaysia and Saudi Arabia.

The article starts by exploring the history of lipsticks and how they have evolved over the years. It then goes on to describe the various formulations used in modern lipsticks, including the ingredients used to achieve different textures and colours. The authors also discuss the manufacturing process of lipsticks, which involves several stages, including melting, mixing, and pouring.

Paper drinking straws are useful because they are a more environmentally friendly alternative to plastic straws. Plastic straws are not biodegradable and can take hundreds of years to break down in the environment, potentially harming wildlife and polluting oceans. In contrast, paper straws are biodegradable and can be easily disposed of in a more sustainable manner. Additionally, paper straws are a renewable resource, as they can be made from sustainably sourced materials such as bamboo.

However, paper straws are not as durable as plastic straws and can become soggy and disintegrate in a short amount of time, especially if left in a drink for too long. They are also more limited in their use – they are not suitable for all types of drinks, especially thicker liquids, like smoothies or milkshakes, which can cause the straw to soften and disintegrate quickly.
