VITANICS-HP : Superior Oil-in Water Nanoemulsifiers CTFA INCI Name : PPG-m Tocophereth-n
VITANICS-HP superior o/w nanoemulsifiers are a novel and innovative patented class of antioxidative polymeric surfactants that open new possibilities for the creation and optimization of nanoemulsion formulations to allow development of unique products for the cosmetic, drug, and food industries.
VITANICS-HP superior o/w nanoemulsifiers are produced by polypropoxylation of polyethoxylated vitamin E (tocopherol), resulting in superior-performance antioxidative emulsifiers, vesicle formers, and dispersants. Their efficiency stems from their role in the stabilization of oil droplets and hydrophobic particles against coalescence and/or flocculation, through a mechanism known as steric stabilization by forming epitaxial mesophase layers. So VITANICS-HP (30/10, 50/20, 70/30, 100/70), the first optimized surfactants of this range, can significantly improve formulations based on nanoemulsions, emulsions, vesicles, and nanodispersion systems. VITANICS-HP also open opportunities for easy and efficient manufacturing method of nanoemulsions at 1 atmospheric pressure with excellent stability and large oil phase content, resulting in new and innovatively superior properties.
VITANICS-LP : Superior Water-in-Oil Nanoemulsifiers
VITANICS-LP amphiphiles act not only as efficient w/o nanoemulsifiers and emulsifiers but also as emollients, and skin protecting agents from UVB-radiation exposure.
VITANICS-AO : Novel In Vivo Antioxidants
Vitamin E is a popular free radical scavenger and antioxidant. However, vitamin E degrades when exposed to oxygen, high temperature and metal ions. VITANICS-AO amphiphiles do not degrade under normal conditions, and are particularly useful in products where the activity of vitamin E might normally be adversely affected by other ingredients in the products.
VITANICS-HP : Superior O/W Nanoemulsifiers Major benefits : Superior Productivity and Quality
Nanoemulsions have become increasingly important as potential vehicles for controlling the delivery of cosmetics, for optimizing the disposition of active ingredients in particular skin layers and for their good stability and moisturizing effect. The preparation of conventional nanoemulsions typically requires a high-pressure homogenizer such as a Microfludizer at 800 to 1,600 atmospheric pressures, relatively high phospholipid concentration and raises skin safety concerns, limiting their practical applications in cosmetics and drugs. O/W nanoemulsions prepared using a high-pressure homogenizer usually can not contain more than 20% oil phase content, limiting formulations can be handled. VITANICS-HP superior o/w nanoemulsifiers allow preparation of innovative creams and very low viscosity nanoemulsions in the size range of 70-200 nm with only 2-3% emulsifier content and oil phase content up to 80% at 1 atmospheric pressure by simple high-speed stirring. VITANICS-HP superior o/w nanoemulsifiers can also be used as solubilizers, dispersing agents and gelling agents.
VITANICS-LP : Superior W/O Nanoemulsifiers Major benefits : Superior Productivity and Antioxidative Protection of Skin and Hair
VITANICS-AO : Novel In Vivo Antioxidants Major benefits : Protection of Skin by Depressing Erythema Development and Prevention of Skin from Melanin Formations
When VITANICS-AO amphiphiles were applied on human skin before and after UVB-irradiation respectively, they showed significant skin protecting effects by depressing erythema development and preventing skin from melanin formation. This proves that VITANICS-AO has antioxidative activities and/or anti-inflammation effects. VITANICS-AO is considered to have significant free radical scavenging effects against singlet oxygen.

Detailed toxicity data are available upon request.
Chemical and Biological Properties
The addition of VITANICS to evening primerose oils (EPO) resulted in the retardation of oxidative deterioration of the EPO. VITANICS-AO (0/5) showed a relatively good in vivo antioxidative activity.
Protective Effects of VITANICS-AO on UVB-Irradiated Human Skin
VITANICS-AO amphiphiles suppress the singlet oxygen induction on UVB-irradiated human skin. Pre- and post-applications of VITANICS-AO on UVB-irradiated human skin showed protective effects by suppressing erythema development and melanin formation, which means that VITANICS-AO has in vivo antioxidative activities and /or anti-inflammation effects. Both pre- and post-applications of 1wt.% solutions, VITANICS-AO (0/5) has better skin protective effects on UVB-irradiated skin than tocopheryl acetate and α-tocopherol, respectively.

Applications in Cosmetics as Surfactants
1. Liquid Crystal Formation
Liquid crystals are indicative of a mesomorphic state and are considered a prerequisite state for phospholipids to form vesicles or nanoemulsions. It is recognized that the appearance of these structures in emulsions modifies certain physical parameters. Of particular interest is that liquid crystals increase viscosity through a modification of van der Waals forces and thus lead to improved stability. It is well known that the presence of liquid crystals in products also improves the moisturizing effects. VITANICS-HP amphiphiles easily form liquid crystals in isotropic solution and o/w nanoemulsions as shown in the photographs below, thus contributing to the higher stability of nanoemulsions.

4. Vesicle Formation
Recently, attention has focused on commercialization of liposomes for therapeutic, diagnostic applications and cosmeceuticals. One drawback of phospholipid liposomes is their oxidation instability. The formation and behavior of lipid peroxides have been strongly implicated in mediating cell injuries and tissue damage in vivo. VITANICS-AO (0/5) forms closed bilayer vesicles in 10wt.% ethanolic aqueous solution by sonication. Since vesicles of anti-oxidative VITANICS-AO are considered to be stable to auto-oxidation, they have the potentialto be used in drug delivery systems as well as in cosmeceuticals. The TEMs of 2wt.% uranyl acetate stained vesicles of 5wt.% VITANICS-AO (0/5) are shown in the microphotographs below.
The left and right microphotographs are the TEMs for the 2wt.% uranyl acetate stained vesicles of 5wt.% VITANICS-AO (0/5) in 10wt.% ethanolic aqueous solution.
Compatibility
All nonionic VITANICS amphiphiles are compatible with anionic, cationic, and nonionic materials so they can be used in all types of formulations without compatibility problems.

Example formulas and specifications of o/w cream nanoemulsions with VITANICS-HP are shown in the table below, which shows that the quality of nanoemulsions with VITANICS-HP is superior to that of nanoemulsions with phospholipids prepared using a high-pressure homogenizer. The morphology of o/w nanoemulsion formulas No. 1 above by cryo-TEM and No. 2 by cryo-SEM are shown in the microphotographs below, which show the nanoemulsions in the size range of 70 -160nm.

4. Vesicle Formation
Recently, attention has focused on commercialization of liposomes for therapeutic, diagnostic applications and cosmeceuticals. One drawback of phospholipid liposomes is their oxidation instability. The formation and behavior of lipid peroxides have been strongly implicated in mediating cell injuries and tissue damage in vivo. VITANICS-AO (0/5) forms closed bilayer vesicles in 10wt.% ethanolic aqueous solution by sonication. Since vesicles of anti-oxidative VITANICS-AO are considered to be stable to auto-oxidation, they have the potentialto be used in drug delivery systems as well as in cosmeceuticals. The TEMs of 2wt.% uranyl acetate stained vesicles of 5wt.% VITANICS-AO (0/5) are shown in the microphotographs below.
The left and right microphotographs are the TEMs for the 2wt.% uranyl acetate stained vesicles of 5wt.% VITANICS-AO (0/5) in 10wt.% ethanolic aqueous solution.
Compatibility
All nonionic VITANICS amphiphiles are compatible with anionic, cationic, and nonionic materials so they can be used in all types of formulations without compatibility problems.
