Vitamins & provitamins
Vitamins are known for their critical role in human health and in all body tissues, including the skin. Some vitamins, such as vitamins A and E, or pantothenic acid in the form of panthenol, are not only ingested. They can be applied directly to the skin to protect its structure or prevent premature aging.
Many vitamins and provitamins are included in nearly all exclusive beauty products. Due to their ability to fight the harmful effects of sunlight UV irradiation, immunity-enhancing function, and anti-inflammatory properties, they have significant protective effects on the skin.
Pyridoxine Cyclic Phosphate is a white to light yellow powder, a stable Vitamin B6 derivative for skin and hair care preparations. It exhibits good stability under sunlight and heat, at a pH range of 6.5-8.0, and good compatibility with other vitamins.
Pyridoxine Dipalmitate (Vitamin B6 Dipalmitate) is a white or similar white crystal or crystalline powder; odorless. It can be easily dissolved in oil, slightly dissolved in ethanol by hot, and cannot be dissolved in water.
Reticap is a polymeric microencapsulated retinol specifically designed to keep its activity due to the stability enhancement in its formulation. This complex is a stable aqueous dispersion.
Retinol 15 D is a vitamin complex, yellow oil that may crystallize at temperatures below 0 °C; approx. 15 % solution of retinol in caprylic/capric triglyceride stabilized with BHT. It is miscible with fats and oils.
Retinyl Acetate is a vitamin A ester with acetic acid, an active ingredient for skin and oral care applications. It is an oily yellow liquid at room temperature (it may contain some crystals of vitamin A acetate) with a mild odor.
Retinyl Palmitate/Carrot Polypeptide is an ingredient known under the trade name Vitazyme™ A. It is a retinyl palmitate polypeptide conjugate, where retinyl palmitate bonded covalently with a natural polypeptide derived from a carrot.
RetiStar™ is a stabilized retinol in an oily dispersion. Traditionally, retinol in formulation requires the use of inert gas technology during manufacturing and packaging for its stability.
Silicone Quaternium-2 Panthenol Succinate is a silicone panthenol quaternary compound that has outstanding substantivity to hair. It is a water-soluble clear liquid with a mild odor.
Tetrahexyldecyl Ascorbate is the tetra-ester of l-ascorbic acid and 2-hexadecenoic acid, which means that Vitamin C conjugated (esterized) with four lipophilic parts of the 2-hexadecenoic version of isopalmitic acid (an isomer of palmitic acid), which makes it very stable in formulations and give
Vitamin E (tocopherol) has been shown to take part in a number of different biochemical reactions in the body. It is a powerful free radical scavenger, boosts immune function, and helps in the formation of red blood cells along with the trace minerals, selenium, vitamin A, and vitamin K.
UTMF Retinol is a complex with a silicone-based delivery system for retinol stabilization inside skin semi-occlusive film-formers.
Vitadex is a multifunctional vitamin complex with lifting, antiwrinkle, and local microcirculation improvement properties — including three cosmetic activities. It is a clear yellowish water-soluble liquid with a characteristic odor.
vitAlease 3.3 is a complex with high retinol levels (3.3 %) in wax capsules for every formulation.
Retinol is a challenging ingredient for cosmetic products. Formulators face two challenges: first, increasing the stability of retinol in cosmetic applications to prevent its degradation and maintain its effectiveness, and second, minimizing the potential side effects of skin irritation.
Vitazyme® A-Plus is a retinyl palmitate/carrot protein/beta-carotene complex, which, in contrast to all commercially available forms of vitamin A, delivers the vitamin as a water-dispersible substance.
