Pre-Mature Skin Aging: Strategies and ingredients to slow down skin aging and evaluation methods to ascertain the achievable improvements (IT)
MgO: evaluation of the influence on SPF (IT)
For over 15 years Cometech has been a distributor of important companies producing raw materials and a trusted partner of the main Italian cosmetic companies. In addition to maintaining and giving continuity to the trade in chemical products, Cometech intends primarily to develop a cooperative activity with its customers. Establish relationships of mutual exchange of information, carry out fruitful collaborations and thus become an important point of reference. Thanks to a small but well-equipped laboratory, Cometech is able to provide its customers with valid technical and formative support.
The aim of the thesis work was to study the potential of the use of Magnesium Oxide as an inorganic filter in formulations for solar products. In a first phase, the MgO sample was structurally and morphologically characterized by X-ray diffraction (XRD) and electronic scanning microscopy (SEM). Subsequently, the filtering power of MgO was verified in synergy with other organic and inorganic filters, in order to obtain cosmetic formulations in the form of an anhydrous sticks that could satisfy the market requirements so generally high SPF, absence of "white effect" and good touch on the skin.

Photoprotection against skin aging: Formulation Strategies and in-vitro methods (IT)
Sunscreens are the most commonly used products to protect the skin from the damaging effects of ultraviolet radiation. An ideal sunscreen should be characterized by high substantivity and its action should therefore be limited to the skin surface or to the upper part of the stratum corneum; they must not penetrate the viable epidermis, the dermis and systemic circulation, nor the hair follicle. The research for methods able to assess the skin penetration of sunscreens is today even more important than in the past, due to the widespread use of nanomaterials and new discoveries in the cosmetic formulations technology. The degree of penetration strongly depends on the physico-chemical properties of the active compound, on the nature of the vehicle in which the sunscreen is formulated and on numerous factors related to the skin. In fact, both the molecular weight and the lipophilicity of the molecule play an important role in skin penetration, just as it has been shown that skin permeation and retention from topically applied substances may differ significantly depending on the formulations used. In recent years, several in vitro studies have focused attention on the various methodological approaches used to effectively evaluate the permeation and distribution of sunscreens in the skin, in light of the entry into force of the EU / 1223/2009 Cosmetic Regulation, the ban of animal testing for cosmetic purposes and the advent of nanotechnologies

New trends: From Bio to Techno (IT)
Society is ageing and the concept of “old age“ has long been the subject of changes and revisions. Skin aging is a physiological process and we can’t reverse it, what we can do is formulate products to try to have a beautiful skin at all ages, through a constant search for active ingredients ranging from bio to technology.

Epidermal Hydration “Debt”.
The wettability of the skin can be performed with a drop of water deposited on its surface using the contact angle method. The “water-drop” can be assumed as a physiological marker capable to evaluate the surface free energy of skin and its polar component and dispersion component. The wettabity of skin and its surface free energy can be evaluated directly and in a non-invasive way using a Tenskinmeter®. The Tenskinmeter® was used for the application of the Tenskinmeter Versus Skin (TVS) -skin test, an evaluation tool capable to determine the hydration of skin and its functionality. This work aims the development of a model capable to correlate the water contain of skin and its surface free energy. On these basis, the “skin hydration debit” was here developed in order to determine the hydration needs of the stratum corneum.
