Contipro launches new cosmetic actives delivery system
The revolutionary Delcore delivery system has been developed to improve the penetration of active substances through the stratum corneum and therefore achieve a stronger effect.
Active cosmetic substances mitigating the signs of aging and maintaining our youthful appearance are effective in the lower layers of the dermis and epidermis, and raw material producer Contipro is targeting for its new launch at in-cosmetics.
Skin carrier
“The role of the carrier is to package a substance that otherwise finds it difficult to reach past the top layer of the skin,” says Dr Muthny, head of Contipro’s anti-aging ingredient development team, as he explained the benefits of the delivery system.
“The carrier carries the substance inside the skin, where it releases the active compound. The advantage is that we can use a much smaller amount of expensive active substances because, thanks to the improved penetration, it is enough to apply just a fraction of the amount used previously.”
Alternatively, Muthny explains that Contipro can load the carrier with a substance which would not penetrate deeper into the skin at all of its own accord, paving the way for the sparing application of previously unusable natural substances in anti-aging cosmetics.
Claims and tests
The Delcore uses chemically modified hyaluronic acid, which is a substance naturally occurring in the human body, so no synthetic compounds can enter the skin.
The modification has made it possible to create short chains from this natural polymeric substance, which is a natural part of the extracellular matrix. Contipro claims those chains can be packaged into a miniature micelle which envelops the selected active anti-aging ingredient inside.
Following delivery of the substance to the lower layers of the skin and the collapse of the micelle, the carrier itself acts against the effects of skin aging.
In-vivo tests showed that the carrier itself adjusts the amount of sebum on the surface, which is generally lacking in ageing skin. In addition, it acts as an antioxidant.
