On the back of a jar not only the extracts and useful additives which are a part of cream, but also a number of ingredients with which not everyone is familiar are always registered. And whether you reflected sometime what, actually, cream consists of?
Any cream, or cream weight, consists, first of all, of a basis to which humidifiers, fragrant substances, extracts and useful additives, preservatives and dyes are added. Let`s consider structure of cream weight in more detail.
the Basis consists of fatty raw materials which can be both a vegetable, and animal origin, and also gel-forming substances, emolent and emulsifiers.
Fats actively nourish skin, make up for loss of skin fat. Most often in cosmetics apply olive, corn, castor oils, cocoa butter, chicken fat.
Gel-forming substances allow to regulate a consistence, give to creams stability and beautiful appearance.
Emolenta keep moisture. For example, silicone - emolent, temporarily improves appearance of skin.
Emulsifiers increase solubility of substances in water, in proportion mix all components.
As a rule, as humidifiers use allantoin, hyaluronic acid, D - pantenol, propylene glycol.
Initially substance under the name allantoin was found in embryonic tissues of birds (“ allantois “ - name of one of embryonic covers). But unlike animals, the human body cannot synthesize allantoin therefore scientists long time tried to find other natural sources of this substance. Is later it was revealed what allantoin contains in plant roots “ Comfrey medicinal “. It is used for a long time for healing and restoration of the damaged fabrics (possesses the same properties, as allantoin from embryonic tissues of birds), softens and humidifies.
Hyaluronic acid is a branched polysaccharide - glyukozamid. At interaction with water forms a protective film. Prevents moisture loss. It is necessary for maintenance of normal water balance in skin of the person. As hyaluronic acid is a natural component of skin, its use does not cause irritation and emergence of allergic reactions. After use of cosmetics on the basis of hyaluronic acid appearance of skin considerably improves, it becomes more gentle and soft.

Glycerin moistens skin, reduces evaporation of water from its surface, has antiseptic effect, promotes the best distribution of cosmetics on skin. In cosmetics it is used in the diluted look as pure glycerin can dry skin, on the contrary.
Fragrant substancesFragrant call
the substances possessing a pleasant specific smell which they are capable to transfer to other components, “ to otdushivat “ them.
The fragrant substances applied in cosmetic products can be natural (an animal or a phytogenesis) and synthetic, received as a result of chemical processing of raw materials.
Extracts and useful additives
Extracts can also be a vegetable or animal origin. Extract - an extraction product (extraction, extracts) active components from different types of raw materials. A typical example of extraction is the zavarivaniye of tea or coffee. Depending on the nature of an ekstragent distinguish water, spirit, oil extracts. In an example with tea water extract turns out.
