Innovative technology paves the way for active
substances to penetrate deep into the skin
VITISPHERES® ENCAPSULATED
ACTIVE INGREDIENTS
CONVENTIONAL ACTIVE INGREDIENTS LACK STABILITY DURING PROCESSING AND APPLICATION
According to survey results, the majority of consumers struggle with more than one skin issue – from lines and a dull complexion, moisture loss and uneven color tone to sensitive skin. The demand for active ingredients which make a major contribution to skin health is entirely understandable. What people want are skin care products which are easy to apply and help their skin combat problems using pure, active ingredients.
There are various methods of integrating active substances into cosmetic products. A pure active ingredient disintegrates too quickly to reach the concentration needed for effectiveness in the end product. Stabilizers do slow down this process of disintegration, but can produce undesirable side effects. Protective compounds around the active ingredients can preserve them from disintegration, but hinder their effectiveness. Some encapsulation technologies burst at once, and supply the skin with an »overdose« of active substances which can lead to skin irritations.
Solution – Innovative carrier system
With Clariant’s newly developed VitiSpheres® technology, active cosmetic substances are able to penetrate deep into the skin. Unlike other carrier systems, such as liposomes, VitiSpheres® does not disintegrate, for example when blended into a cream, but hold the active ingredient firmly inside themselves, until they are applied to the skin. Only then the casing slowly dissolves, and the active substance penetrates the deep layers of the skin. There are two variations on this technology: for oil-soluble active ingredients (such as Tocopherol, Retinol, etc.) and also for water-soluble substances (such as Vitamin C).
ENSURES LONG-TERM PROTECTION OF ACTIVE INGREDIENTS
SMART ENCAPSULATION TECHNOLOGY FOR HIGHLY EFFICIENT ACTIVE INGREDIENTS
The VitiSpheres® technology newly developed by Clariant uses ball-shaped structures to carry active ingredients – »spheres« – which contain the oil or water-soluble active substance inside them. As soon as the spheres reach the skin, they form an ultra-thin film on the surface. This film prevents what is known as transepidermal water loss (TEWL), the evaporation of water from the top layer of the skin. The water remaining in the skin then becomes somewhat »trapped«, and increases the gap between the lipid membranes. As the viscosity of the layer enveloping the spheres reduces, the oil-soluble active ingredients contained can now combine with the lipids (fats) incorporated in the skin, and penetrate deeper into the skin. Following the natural tendency of the cells to balance out differences in concentration, the oil-soluble lipids move automatically from the highly-concentrated environment of the spheres into the deep layers of the skin.
VitiSpheres® Hydro
The version for water-soluble ingredients, VitiSpheres® Hydro, works along similar lines, although in this case the water-soluble active ingredients are carried to the deeper layers of the skin by the skin’s own non-evaporated water, instead of its own lipids.
