research Effect of Tocopheryl Polyethylene Glycol Succinate on the Percutaneous Penetration of Minoxidil from Water/Ethanol/Polyethylene Glycol 400 Solutions
In this study, adding TPGS to a minoxidil formulation improved local retention and reduced systemic absorption in certain solvent mixes, particularly with a balance of alcohol and PEG 400.
research A Mixture of Tocopherol Acetate and L-Menthol Synergistically Promotes Hair Growth in C57BL/6 Mice
In this study, a mixture of tocopherol acetate, L-menthol, and stevioside was more effective in promoting hair growth in mice compared to tocopherol acetate or L-menthol alone.
research Tocopherol Contents and Antioxidant Activity in Grape Pomace After Fermentation and Alcohol Distillation
This study found that grape pomace from Georgian winemaking contains significant tocopherols and antioxidant activity, suggesting it could be a valuable resource for the pharmaceutical and food industries.
research Stability Studies on L-Ascorbic Acid DL-Alpha-Tocopherol Phosphoric Acid Diester Potassium Salt (EPC-K)
In this study, EPC-K, a compound with antioxidant and moisturizing effects, was found to decompose significantly under certain conditions, impacting its stability in quasi drug hair-growing products.
research Co-Delivery of Minoxidil and Tocopherol Acetate Ethosomes to Reshape the Hair Follicle Microenvironment and Promote Hair Regeneration in Androgenetic Alopecia
This study found that ethosome-loaded minoxidil and tocopherol acetate improved hair regeneration and regulated the microenvironment around hair follicles better than commercial minoxidil in androgenic alopecia model mice, showing promise as a treatment strategy.
research Adverse Reactions to Ethinylestradiol, Salicylic Acid, Swertia Japonica, and Tocopherol Acetate in Female Pattern Hair Loss Treatment
Two women had skin reactions from a hair loss treatment and got better after stopping use.
research Efficacy in Alopecia of an Anti-Hair Loss Conditioner with Serenoa Serrulata and Tocopherol. Pilot Study
This study aimed to evaluate the effectiveness of a hair conditioner containing Serenoa serrulata extract and tocoferol applied 3-4 times per week for 90 days against androgenic alopecia.
research Simultaneous Effects of Tocopheryl Polyethylene Glycol Succinate on Local Hair Growth Promotion and Systemic Absorption of Topically Applied Minoxidil in a Mouse Model
This study found that incorporating 0.5% TPGS into topical minoxidil solutions enhanced hair growth in mice, although increasing TPGS to 2% decreased effectiveness.
research Simultaneous Effects of Tocopheryl Polyethylene Glycol Succinate on Local Hair Growth Promotion and Systemic Absorption of Topically Applied Minoxidil in a Mouse Model
In this study, a 0.5% addition of TPGS to topical minoxidil solutions increased hair growth in mice, but higher concentrations reduced this benefit.
research Alpha Tocopherol-Nanocellulose Loaded Alginate Membranes and Pluronic Hydrogels for Diabetic Wound Healing
This study found that using a combination of Alginate-TEMPO-oxidized cellulose nanofiber-α-tocopherol membranes and Pluronic-α-tocopherol hydrogels facilitated better wound healing in diabetic rats through enhanced angiogenesis and no observable toxicity compared to using each treatment individually.
research Percutaneous Absorption of Alpha-Tocopheryl Acetate
This study found that α-tocopheryl acetate is well absorbed through healthy skin, with absorption occurring through specific pathways and showing high affinity for small blood vessels.
research High-Dose Alpha-Tocopherol as a Preventive of Doxorubicin-Induced Alopecia
This study found that alpha-tocopherol acetate did not demonstrate any protective effect against hair loss induced by doxorubicin in patients with solid tumors.
research High-Performance Liquid Chromatographic Determination of α-Tocopheryl Nicotinate in Cosmetic Preparations
This study developed a rapid, precise, and specific chromatographic method to measure alpha-tocopheryl nicotinate in cosmetics, using alpha-tocopheryl acetate as an internal standard.
research Sustained Effect of Two Antioxidants (Oxothiazolidine and δ-Tocopheryl Glucoside) for Immediate and Long-Term Sun Protection in a Sunscreen Emulsion Based on Their Different Penetrating Properties
This study found that a sunscreen with oxothiazolidine and δ-tocopheryl glucoside provided complementary oxidative protection, with immediate but brief effects from oxothiazolidine and prolonged effects from the slower-absorbing δ-tocopheryl glucoside.
research Effect of Alpha-Tocopheryl Acetate, Retinyl Palmitate, and Phytantriol on Hair Protection
This study found that TRP-hair essence significantly protected and improved the quality of human hair, particularly against heat stress, by enhancing cuticle health and maintaining hair color.
research Quantitative Determination of Alpha-Tocopherol and Alpha-Tocopheryl Acetate in Pharmaceutical and Supplementary Soft Capsules by High Performance Liquid Chromatography
In this study, the researchers developed a chromatographic method to determine α-tocopherol and α-tocopheryl acetate in pharmaceutical capsules with high accuracy and repeatability, establishing it as a reliable alternative for analyzing these compounds.
research Identification of Hepatic Molecular Mechanisms of Action of Alpha-Tocopherol Using Global Gene Expression Profile Analysis in Rats
This study found that dietary vitamin E influenced gene expression in rat livers, altering genes related to metabolism, coagulation, and steroid processing, and confirmed its effects on related biological endpoints.
research RP-HPLC Determination of Quercetin in a Novel D-Alpha-Tocopherol Polyethylene Glycol 1000 Succinate Based SNEDDS Formulation: Pharmacokinetics in Rat Plasma
This study found that a new quercetin-loaded self-nanoemulsifying drug delivery system improved quercetin bioavailability by 149.8% compared to its suspension in rats.
research Controlled Release of the Alpha-Tocopherol-Derived Metabolite Alpha-13'-Carboxychromanol from Bacterial Nanocellulose Wound Cover Improves Wound Healing
This study found that α-13′-carboxychromanol significantly accelerated wound healing and improved tissue quality in a mouse model, especially when delivered with bacterial nanocellulose under diabetic conditions.
research Treatment of Del(5q) Myelodysplastic Syndrome with All-Trans-Retinoic Acid and Tocopherol-Alpha
This study concluded that the combination of all-trans-retinoic acid and tocopherol-α is not recommended for treating del(5q) myelodysplastic syndromes due to low efficacy and high incidence of adverse effects.
