Some ingredients, even natural ones, can pose a risk of allergies or irritation to sensitive people. Before using a cosmetic product, a test on the inner fold of the elbow is recommended in order to check for unpleasant reactions (itching, redness).
Some phases of cosmetic compositions require heating, so precautions must be taken to avoid burns. Some procedures involve the use of alcohol or flammable ingredients, handle them carefully. When preparing recipes that include powdered ingredients, it is recommended to wear a protective mask and goggles. When handling essences and various concentrated ingredients, for avoiding contact with skin it is recommended to wear gloves. In case of eye contact with any ingredient, rinse with plenty of water. If persistent irritation or unpleasant symptoms occur, seek medical attention.
From a microbiological point of view, in addition to preserving and storing cosmetic compositions in optimal conditions, it is very important to prepare them in a hygienic environment, with clean utensils.
All cosmetic compositions containing water are susceptible to microbiological contamination, so they must be preserved and hygiene is essential during the manufacturing procedure:
Disinfection of utensils
All utensils should be disinfected shortly before use. First they are washed with water and dishwashing detergent, rinsed, drained and left to dry. Then wipe with a cloth or paper towel soaked in 70° alcohol. The utensils are then placed on a clean towel until dry. Depending on the shape of the utensils, the alcohol can also be sprayed. It is recommended to wear gloves that protect your hands from the alcohol, especially when disinfecting several utensils.
Another possibility of disinfection is that performed by boiling. In a saucepan start boiling water with 1-2 tablespoons of vinegar. Only utensils and containers that are heat-resistant can be disinfected in this way. A kitchen towel is placed on the bottom of the pan. Boiling is recommended to last between 10 and 15 minutes. It is recommended that the operation is done shortly before using the utensils.
Disinfection of containers
Both new and reused containers will be washed with water and dishwashing detergent and then rinsed with cold water and placed to dry on a textile or paper towel. After drying, wipe with a towel soaked in 70° alcohol.
All disinfected utensils and containers should be used on the same day, as soon as possible after disinfection.
Ingredients should be dosed by pouring, dripping or sampling using disinfected utensils (spoons, pipettes, syringes). All operations will be performed with clean hands.
Both aqueous and oily compositions must be protected from heat, direct light and a humid environment. They keep well in a cool environment, which means below 24°C, provided they are hygienically prepared and stored properly. Most cosmetic compositions can also be stored in the refrigerator. Compositions and ingredients sensitive to oxidation or microbiological pollution should be stored in the refrigerator.
The compositions kept in "contactless" bottles (with sprayer, atomizer, pump...) that thus do not come into contact with the hands or in "airless" type bottles that do not come into contact with the air are quite well protected from microbiological contamination and oxidation. When using water-containing compositions that are stored in jar-type containers, the use of a spatula is recommended. Exclusively oily cosmetic compositions can be handled with clean hands, as they are not sensitive to microorganisms.
We recommend labeling the compositions with information regarding the name, expiration date and composition. Keep products out of the reach of children.
Essential oils are concentrated compositions that can cause serious damage if not used properly. Essential oils are not to be directly applied to the skin, but aromatherapists may recommend undiluted application in some cases. Read on about the safe use of essential oils.
Vegetable oils can be applied to the skin as such, with few exceptions. They are also considered carrier oils (bases) for a number of cosmetic active ingredients that also include essential oils, special vegetable oils or CO2 extracts for example. Macerates are oily extracts of plants, fruits, flowers or parts of plants that have fat-soluble active principles. Special vegetable oils - which are not considered carriers - are concentrated, have a rich and precious composition, and are usually not used undiluted on the skin. Pure vegetable butters can be used applied to the skin as such, or can be included as ingredients for the formulation of creams, ointments, body oils and various cosmetic compositions together with essential oils, cosmetic vitamins, vegetable extracts, floral waters, vegetable oils and cosmetic active ingredients.
