Indonesia is one of the largest cinnamon producers that supplies most of the world's international markets. Cinnamomum (Cinnamommum burmannii) including Lauraceous family, Cinnamomum clan which consists of hundreds of species in Asia and Australia, one of which is Cinnamomum burmanii, which is widely cultivated in Indonesia. Cinnamon is known as one type of spice oldest in the world. Cinnamon bark, branches and branches can be used as spices and are one of Indonesia's export commodities. From the phytochemical aspect of cinnamon has almost all of the parts of the plant containing essential oils with different compositions, the cinnamon leaves also contain essential oils which are potential enough to be utilized. The use of cinnamon leaves is an effort to optimize the benefits of a type of plant. In addition to extracts, cinnamon leaves are also used through leaf distillation to obtain cinnamon leaf essential oil.
Of the total 28,000 species of medicinal plants in Indonesia, 1,845 have been identified as drug-like properties, and there are 283 active species explored by the compounds . Some types of plants can be processed in advance to produce oil with a distinctive aroma and can be used directly or by derivative products. This oil is called essential oil which is currently in the spotlight of the body care industry because it is not only able to nourish the skin well, but also ultrasonic, fast and easily absorbed.
Market demand for essential oils both domestically and abroad is increasing. In accordance with export data from the Ministry of Industry of the Republic of Indonesia, the export of cinnamon (Cinnamon and cinnamon-tree flowers, crushed or ground) has a trend of 18.65% while exports of essential oils (essential oil of lemon grass, citronella, nutmeg, cinnamon, ginger) have 10.98% trend.

In experiments in a lab, cinnamon oil is able to kill rickettsia (microorganisms in the form of bacteria but are like viruses, causes of typhus disease) within 12 minutes.
The efficacy of these drugs is inseparable from the activities of chemical components contained in these plants namely essential oils, eugenol, safrole, cinnamaldehyde, tannins, calcium oxalate, resin, and tanners. Its chemical, spicy, slightly sweet, warm and fragrant. The main value of cinnamon is in the skin of the stems, branches and twigs that contain essential oils, especially cinnamaldehyde (60-75%) and eugenol (4-18%) .
Cinnamon contains compounds that function as anti-oxidants. Antioxidants are compounds that can delay, inhibit, or prevent the oxidation process in food so it does not cause rancidity / damage . One chemical component in cinnamon bark is a pale yellow oil-like liquid produced from extracting essential oils such as oil from cloves and cinnamon . Eugenol has the molecular formula C H 0 , and dissolves in alcohol, ether and chloroform. Eugenol is widely used in pharmaceuticals, food and beverage industry, cosmetics and as a raw material for other chemical products. Essential oils obtained from Cinnamomum zeylanicum leaves are rich in eugenol, which is 65-95% which is an important ingredient in the industry of essence.
In addition, cinnamon oil can be used in industrial fields such as mouthwash and pasta, fresheners of soap, detergents, lotions, perfumes and creams. Eugenol is a monohydroxy or phenol cyclic alcohol so it can react with strong bases. Eugenol is volatile colorless or slightly yellow in color and has a bitter taste . Eugenol is used as a perfume raw material, flavoring agent, and in the field of medicine as an antiseptic and anesthetic. Eugenol is also used in the manufacture of isoeugenol to produce synthetic vanillin . The name IUPAC Eugenol is 4-Alil-2- methoxyphenol; Other names, many of which are: 2-Metosi-4- (2-propenyl) phenol, Eugenic Acid, Kariophylic Acid, 1-Alyl-3-methoxy-4-hydroxybenzene, Alilguaiacol, 2-Methoxy-4-Allyphenol, 4- Allyckatecol-2-methyl ether, 2-methoxy-4- (2-propen-1-il) phenol .
The use of cosmetics is now increasingly widespread, one of which is the oldest cleansing cosmetics since centuries ago. Soap is one of the most important and necessary products in everyday life which is a cleaning agent that can be used with water to clean and wash every day.
One of the toiletries that must be in the bathroom is soap. Almost everyone must use soap, especially facial soap and of course it takes healthy soap and has a good content and can provide skin care and also has an affordable price. These soaps can contain essential oils which of course have very good properties. Aside from being an antibacterial it can also remove spots or acne scars on the face. At present there are still many people who choose cosmetics from endangering the skin and having very good properties . One herbal product that is currently being used is herbal soap that has other properties for the skin, especially the face, in addition to cleaning from dirt. The face requires special soap that can overcome problems such as acne, facial spots, or facial moisture problems.
Disorders of the skin such as acne problems are very disturbing appearance and is a disease or inflammation that affects the pilosebaceous composition of the skin which often leaves black stains or black spots which is certainly very disturbing appearance. For this reason, a product face can be used for a long time and can treat acne and disguise black spots or on the face. The product is in the form of herbal facial soap that uses natural ingredients as raw materials such as coconut oil and cinnamon essential oil.
• For bases / alkalis used in making soap are chemicals in the form of NaOH (Sodium or Sodium hydroxide) or KOH (Potassium or Potassium Hydroxide) which are strong (pH above 10). This chemical is hygroscopic (easily absorbs water and corrosive (causes rust). Therefore the use of this material is in need of special attention because it is quite dangerous especially if it is directly in contact with the skin.
• The results of the reaction between fatty acids with NaOH and KOH are different. If you use NaOH, you will get a hard-texture soap, commonly known as solid soap or bar soap. If using KOH will produce liquid soap / cream, depending on the level of dilution used. In this study NaOH will be used to make herbal soap in solid form.
• In addition to the above ingredients, alcohol is also needed to dissolve NaOH, an additive in the form of cinnamon essential oil and granulated sugar in addition to making transparent solid soap which serves to help form transparency in soap (Hambali, 2005). Transparent solid soap is soap the shower is shaped like a bar with a transparent appearance, resulting in softer foam on the skin and more shiny appearance than other types of soap so it looks more attractive .
2. Methods and Equipment
Samples were taken by purposive sampling, namely samples that have certain conditions, namely women aged 30 - 45 years, and have dry facial skin and mild black spots Field workers, do not use contraceptives, such as birth control pills or injections, are not in medical care or treatment beauty experts with regard to dryness and black spots on the skin of the face.
Samples were taken as many as 10 facial skins, which were divided into 2 groups, namely 5 facial skins treated with Cinnamon Soap and the rest were treated with mask control. All samples were treated 8 times for 1 month.
Cinnamon soap is made by means of a saponification process that has been washed and then the results of the soap are applied to the face of the sample which has been coated with gauze. Soap is applied to the face for 5-10 minutes. The results showed that there were essential oils in the soap and curcuminoid compounds which could reduce mild black spots and moisturize dry skin. Before and after treatment the samples were measured on black spots on the face with an Analyze Skin Pigmentation instrument as an instrument of this study.

Based on the results of the study, the two types of masks used, Cinnamon soap and control masks, have an effect on the reduction of dark black spots on the facial skin. However, based on the description above, it can be seen from the two masks used in this study (Cinnamon soap and control masks) which have the greatest influence on the reduction of mild black spots on the face is the use of Cinnamon soap. It is also based on research data that shows that from 1 to 8 treatments in all samples, the results of the reduction of mild black spots using Cinnamon soap are more influential than the control masks can be seen from Figure 2. Based on the results of the study, both soap and mask types used were Cinnamon soap and control masks which had an effect on the reduction of dark black spots on facial skin. However, based on the description above, it can be seen from the two masks used in this study (Cinnamon soap and control masks) which have the greatest influence on the reduction of mild black spots on the face is the use of Cinnamon soap.
Cinnamon has antibacterial properties, and is good for preventing skin problems such as hives and fungi . Antibacterial components in cinnamon include oil volatile compounds containing cinnamaldehyde (cinnamaldehyde) compounds, and polyphenol compounds namely proanthocyanin (proanthocyanidin).
Cinnamon has an eugenol compound of 3.11% and cinnamaldehyde (90.24%) and coumarin (53.46%) , which has been shown to reduce acne stains on oily facial skin and affect thinning, stain area and speed of acne removal . Besides cinnamon also contains vitamin C which acts to protect the skin from the effects of bad UV rays that cause premature aging and prevent the formation of melanin .
Cinnamon is also rich in antioxidants that can slow down the aging process. Besides that cinnamon also contains lots of vitamins and minerals that are good for skin and hair health. Cinnamon has the effect of blood circulation to reach the hair roots to stimulate hair growth.
In the manufacture of soap, the type of acid used is fatty acids, both animal and vegetable. These fatty acids are generally categorized as weak acids such as frying oil, coconut oil, palm oil, castor oil (Ricinus oil), beef fat, lard, and others. So oil is a natural ingredient in making soap.
Based on the results of the study, it can be concluded that the use of Cinnamon soap affects the reduction of mild black spots on the treatment of dry facial skin in line with the results of hypothesis testing (Ho) which is done using t-test. Based on the calculation results obtained t ttable is 9.375 1.86, then Ho is rejected and H1 is accepted at a significance level of 0.05 with df is 8. So, there is an effect of using Cinnamon soap (Cinnamomum burmanii) on reducing black spots on the skin dry face.
