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

Food Chemistry Journal From raw food to brand label grocery. Why Food Chemistry? I am passionate about food‚ I love discovering new food‚ experimenting with taste‚ play with colors and learn the benefits and why our body needs certain nutrients. Before coming to college I did 2 years of full healthy dishes and read all over internet and books new ways to introduce new nutrients to my diet. During this 2 years I lost weight but except for that I felt clean from the inside‚ more energetic and happier

Keghan Chapter 8 MULTIPLE CHOICE QUESTIONS Topic: Structure Elucidation 1. An alkene adds hydrogen in the presence of a catalyst to give 3‚4-dimethylhexane. Ozonolysis of the alkene followed by treatment with zinc and acetic acid gives a single organic product. The structure of the alkene is: CH3 A) CH3CH=C-CHCH2CH3 (cis or trans) CH3 CH3 B) CH3CH2C=CCH3 (cis or trans) CH2CH3 C) CH3 CH2=CCH2CHCH2CH3 CH3 CH2 D) CH3CH2CCHCH2CH3 CH3 CH3 E) CH3CH2CHCHCH=CH2

The chemical processes that take place inside food determine its nutritional value‚ taste‚ texture and freshness. Like any other organic material‚ food can decompose over a period of time. The importance of food chemistry lies in its ability to counter the effects of decomposition and spoilage and extend the shelf life of foods. Food chemistry is a science that studies the chemical processes that take place in food. All food products are made of biological materials that react and interact in different

CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached

"thermoset". Bakelite is a space-network polymer. Unlike linear and branched polymers‚ which are composed of long molecules that make them more or less crystalline‚ space-network polymers are highly and irregularly cross-linked throughout the structure. The sheer extent of the cross-linking means that a sample of the material is essentially one gigantic molecule. Although heat softens and melts linear and branched polymers‚ heating doesn ’t soften space-network polymers because such a softening would require

Chemistry is the science of dealing with the compounds‚ elements‚ and molecular structure of matter. Essentially‚ chemistry is the science of examining substances and objects to find out what they’re made of and how the react to different conditions.
