Natural zeolites are characterized by multifunctionality and there are three main features that define its successful use in the manufacture of effective cosmetic products.
Sorption (Sorption is a physical and chemical process by which one substance becomes attached to another)
ion exchange (In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions)
The Laboratory “LN-Cosmetics” has carried out successful work for more than 17 years in the development, implementation and promotion of effective cosmetic products, a major component of which is a modified natural zeolite.
UNIQUE PROPERTIES OF THE BIOCHEMICAL MECHANISM ACTIVITY OF ZEOLITES AS THE NEW MATERIALS FOR SKIN CARE
The structure of the skin integument (skin)
Skin - One of the most important organs of the human body. The function of the skin includes providing mechanical, microbiological and chemical isolation of the internal organs from the environment. The construction of the skin is a complex multilayer which includes an outer stratum corneum, dermis of living cells and an extracellular network of collagen fibres or fibrils. The skin collagen fibrils composition forms a two-dimensional network providing elasticity and mechanical properties of the skin.
Collagen - one of the main components of the skin primarily to ensure the mechanical properties of the skin and its durability. At the molecular level microscopic collagen – a fibrillar protein (polypeptide), which is a triple helix, consists of three mutually twisted polypeptide chains. Each chain consists of individual peptides, or amino acid residues which are linked together peptide bonds.
Collagen - hydrated protein containing normal conditions to 180 g of bound water per 100 g dry weight. Since the molecular weight of the amino acid residue is approximately 100 g, then it is clear that one residue accounts for about 10 water molecules (molecular weight of each '18). Water retention in the collagen due to its so-called hydrophilic amino acid composition. Other compounds, such as the protein keratin (hair, nails, claws and horns of animals) are hydrophobic, so in its composition contain very little so-called capillary water.
A characteristic feature is the collagen age dependence of hydration, namely, with increasing age of the water content of the collagen, fibers decrease gradually. Organoleptic water loss of skin collagen is seen as dryness, which increases with ageing of the body. Another factor is the loss of skin elasticity, collagen accompanying loss of water.
The chemical properties of collagen
The chemical properties of collagen makes it a barrier to ion penetration through the skin from the external environment into the body. When collagen reacts with solutions containing calcium or other inorganic heavy metal ions and organic cations – alkaloids occur stereochemical binding reaction of these ions collagen. In particular, calcium ions can enter into a triple helix. Moreover, its conformation changes so that the water molecules retained longer in the data portion of the triple helix, which leads to loss of local water – dehydration. The interaction in vivo human skin with hard water also flows calcination process, followed by the appearance of dryness and skin fragility, loss of elasticity, appearance of wrinkles etc.
This process is used in tanning animal skins (known as liming, chrome and others kinds of tanning). In many cases, the process is irreversible, and “tanned” skin loses its water-binding properties.
In order to avoid unpleasant skin fragility, it is necessary to enter into its composition fatty substances of a different nature (creams), which to some extent mitigate the unpleasant consequences of tanning, but do not change the essence of the chemical process associated with the ageing of the organism.
Experiments have shown that the calcining process is not always irreversible and in some cases and to some extent can be reversed. First of all, as shown by in vitro experiment, calcium can be eliminated from the collagen excess of sodium ions.
Other methods for removing calcium from the use of soft collagen refers ion exchangers such as ion-exchange compositions of bentonite clay powder and different types of volcanic tuff containing clinoptilolite group minerals (zeolites).
The combination of the two methods – the displacement and binding, using saline solution containing sodium ions and mineral ion exchangers, and calcium binding solution and softening the skin, it promotes the achievement of stable and sustainable health and performance properties of the skin for a lengthy period of time.
Mineral sorbents, ion exchangers and live skin.
As indicated above, the main feature of the mineral ion exchangers is that they selectively bind calcium and other heavy metal ions, and ammonium ions, and ammonium-containing organic cation, many of which are responsible for the existence of a specific human skin odour and the ability of dogs to recognize human smell .
The sorption properties of zeolites provide hygienic decongestion of sebaceous and sweat glands, releases the skin of organic products from natural life cycle and the remnants of cosmetics.
Another feature of ion exchange mineral, found in experiments in vitro, is their ability to catalyse the oxidation of sulphur compounds and possibly break disulphide bridges. It is noteworthy that disulphide bridges provide the appearance and preservation of the so-called tertiary structures of proteins through the formation of bonds between the individual portions of the polypeptide chains. Disulphide bridges can also provide a connection or coupling between the scales on the stratum corneum surface of the skin. Since the skin constantly produces particles of horny layer of the epidermis, the outer layers should regularly be rejected. Usually, the process takes place spontaneously, forming part of daily skin care. But in many cases, beauticians resort to various corrosive substances for “radical readings” of the skin, which may lead to disturbances of the skin functions and complications by using such ambiguous methods. The use of natural minerals – catalysts mode provides a softer removal of coarse particles, molecules and dead stratum corneum cells held at the skin surface, including disulphide bridges.
Preparations for deep skin care – Lithocomplex
The composition of the natural salts and natural ion exchangers are environmentally friendly, do not contain toxins and harmful substances and cannot cause direct or indirect harm to human skin and the body as a whole.
Regular used, Lithocomplex provides unmatched purity of skin, deep hygiene, and this is the key to its beauty and health. Every day our skin in a very short time (0,2-1 minute) receives a portion of the “cold bath” without additional burden of a very long stay in high temperature conditions. The effect of purity is very much like the effect achieved after a bath.
Disclosure of the mechanism of action of each of the individual components and their synergy allows us to achieve the best effect and optimization in the application of Lithocomplex, as well as in combination with other products manufactured by the Laboratory “LN-Cosmetics”, which doubles the final prolonged result. Besides Lithocomplex – these products are absolutely compatible with any nutrient cosmetic lines, preferably only those which contain natural ingredients as possible
