We thought and brainstormed about what we are going to do for our investigatory project. One of us gave the idea to concentrate on a particular topic, which is about soap making but after all the long thinking and brainstorming, we decided to come up with a perfume as a product with the use of rose petals. Perfumes and scented products are composed of toxic chemicals like acetone, toluene, ethyl acetate, formaldehyde and ethanol that are found on any list of toxic and hazardous chemicals. All these and other chemicals used in the manufacture of personal care products have been shown in animal studies to cause serious health problems and even death. That’s why we decided to create a natural perfume that is safe for the environment. So we thought that we must encourage the other people to try home-made perfumes or the all organic perfumes. It is safe and you yourself can be satisfied with the smell of the perfume. And the fragrance of rose can create fresh atmosphere. We would first introduce the beggining of perfumes. People have used perfumes on their bodies for thousands of years in lesser or greater amounts dependant on fashion whims. The early Egyptians used perfumed balms as part of religious ceremonies and later as part of pre love making preparations. Other plants such as rose and peppermint were steeped in oils until a perfumed unguent (unguent is a healing ointment ) formed. The late 19th century was the first real era of perfume as we know it when new scents were created because of advances in organic chemistry knowledge. Perfume is made from about 78% to 95% of specially denatured ethyl alcohol and a remainder of essential oils. We found out that the production technique originated in Persia then spread through Arabia and India, and more recently into eastern Europe. In other parts of the world Rose is commonly used. The oil is transparent pale yellow or yellow-grey in colour. Rose water, made as a byproduct of rose oil production, is widely used in Asian and Middle Eastern cuisine. In France there is much use of rose syrup, most commonly made from an extract of rose petals. In the United States, this French rose syrup is used to make rose sconesand marshmallows. Perfumes have been known to exist in some of the earliest human civilizations either through ancient texts or from archaeological digs. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin or coumarin,which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics alone. The precise formulae of commercial perfumes are kept secret.Even if they were widely published, they would be dominated by such complex ingredients and odorants that they would be of little use in providing a guide to the general consumer in description of the experience of a scent. Nonetheless, connoisseurs of perfume can become extremely skillful at identifying components and origins of scents in the same manner as wine experts. The most practical way to start describing a perfume is according to the elements of the fragrance notes of the scent or the "family" it belongs to, all of which affect the overall impression of a perfume from first application to the last lingering hint of scent. Plants have long been used in perfumery as a source of essential oils and aroma compounds. These aromatics are usually secondary metabolites produced by plants as protection against herbivores, infections, as well as to attract pollinators. Plants are by far the largest source of fragrant compounds used in perfumery. The sources of these compounds may be derived from various parts of a plant. A plant can offer more than one source of aromatics, for instance the aerial...
