Tretinoin and Benzoyl Peroxide
A simple, sensitive, spectrophotometric method in UV region has been developed for the simultaneous estimation of benzoyl peroxide and tretinoin in bulk and semi solid dosage form (cream). Standard solution of benzoyl peroxide shows maximum absorbance at 234.8 nm and tretinoin shows maximum absorbance at 348.6 nm. Beer’s Lamberts law is obeyed in concentration range 1-9 μg/ml for tretinoin with...
متن کاملDispersion polymerization of styrene and methyl methacrylate initiated by macromonomeric azoinitiator
The free radical dispersion polymerization of styrene (St) and methyl methacrylate (MMA) initiated by poly(oxyethylene) (PEO) macroazoinimer (MIM-400) in water/ethanol, was investigated at three different temperatures (50, 60 and 80 8C) for seven polymerization times (3, 6, 9, 12, 24, 36 and 48 h). PStPEO and PMMA-PEO networks were obtained. In each case, polymer gel fractions depend on the pol...
متن کاملβ-Peptide coatings by surface-initiated polymerization.
Homopolymers of β-lactams can be grown by surface-initiated polymerization. These surface-linked β-peptides are living polymers with the potential to be utilized as tunable, protease-resistant interfaces in multiphase structural composites where the characteristics of the interface influence bulk properties.
متن کاملEthyl 2-(4-benzoyl-2,5-dimethylphenoxy)acetate
The title compound, C(19)H(20)O(4), was synthesized via a Fries rearrangement of hydr-oxy benzophenone. The dihedral angle between the least-squares planes of the two benzene rings is 69.04 (11)°. The mol-ecular structure displays an intra-molecular non-classical C-H⋯O hydrogen bond.
متن کاملEfficacy of benzoyl peroxide (5.3%) emollient foam and benzoyl peroxide (8%) wash in reducing Propionibacterium acnes on the back.
BACKGROUND Topical treatment of acne vulgaris on the back is challenging largely due to the extensive broad surface with difficult to reach areas. A "leave-on" foam is suited for application to the trunk due to ease of application and spreadability. Prior to this trial, no data on Propionibacterium acnes (P. acnes) reduction on the back has existed for any benzoyl peroxide (BP) formulations or ...
