Chemistry of cosmetics Few people would whip out a chemistry set‚ uncork the vials‚ and slap the compounds on their face. Yet‚ millions of women and girls essentially do that every day when they unzip their makeup bags and apply lipstick‚ mascara‚ and other makeup. Like the compounds in a chemistry set‚ makeup consists of chemicals. Although the chemicals in cosmetic products are intended to improve the appearance of skin‚ lips‚ and lashes‚ some can cause adverse effects. Emulsions The majority

Polymer Chemistry Classification of Polymers – Notes prepared by The most common way of classifying polymers is to separate them into three groups - thermoplastics‚ thermosets‚ and elastomers5. The thermoplastics can be divided into two types - those that are crystalline and those that are amorphous. You may click on the words in the diagram below to learn more about these classifications. Thermoplastics Molecules in a thermoplastic are held together by relatively weak intermolecular
