RiceSorb as Talcum Substitute for Loose Face Powders: Formulation and Characterization.

Excessive and daily inhalation of talcum, a main ingredient of face powders, causes pulmonary talcosis, which has led to the replacement of talcum with safer natural ingredients. RiceSorb, or starch from Japanese rice, was used as an alternative owing to its nontoxic and excellent oil absorption capacity. The objectives of the present work were to formulate loose face powders from RiceSorb and to investigate the physicochemical properties of the prepared formulations.

A Cold Process Preparation of Vetiveria zizanioides (L.) Nash Oil Lotions using Simulgel FL as an Emulsifier.

Vetiveria zizanioides (vetiver) contains viscous volatile oil, which has the ability to repel mosquitoes similar to citronella oil, a well-known mosquito repellent in tropical countries, like Thailand. The objectives of the current study were to formulate the stable oil-in-water vetiver oil lotions using Simulgel FL as a liquid emulsifier, to investigate the physicochemical properties of the prepared lotions and to evaluate the in vitro release characteristics of the stable vetiver oil lotions. In this work, the concentrations of Simulgel FL ranged from 1% to 3% weight in weight, whereas the concentrations of vetiver oil were varied: 2.

Effect of emulsifier pairs on physical stability of emulsions containing three different natural oils.

The purpose of this study was to formulate oil-in-water (o/w) emulsions containing 40% w/w natural oil (i.e., olive oil, rice bran oil, or sesame oil), 10% w/w emulsifier blend, and 50% w/w water.

Physical stability of coconut oil lotions formulated using hydrophile-lipophile balance system of various emulsifier pairs.

The aim of this study was to prepare coconut oil lotions using a hydrophile-lipophile balance system to calculate the proportion of each nonionic surfactant used. The effects of emulsifier pairs in the formulations on physical properties (i.e.

Effects of glucam P-20, vanillin, and fixolide on mosquito repellency of citronella oil lotions.

The objective of this study was to investigate the effects of three fragrance fixatives, Glucam P-20, Vanillin, and Fixolide, on the mosquito repellent property of citronella oil lotions. In the current study, two formulae (A and B) of oil-in-water citronella oil lotions were formulated using different ingredients (emulsifiers [Cremophors or Emulwax], stiffening agents, and emollients). Citronella oil was used at 10% wt:wt.

Controlled release of oral tetrahydrocurcumin from a novel self-emulsifying floating drug delivery system (SEFDDS).

The objectives of this study were to develop and evaluate a novel self-emulsifying floating drug delivery system (SEFDDS) that resulted in improved solubility, dissolution, and controlled release of the poorly water-soluble tetrahydrocurcumin (THC). The formulations of liquid self-emulsifying drug delivery system (SEDDS; mixtures of Labrasol, Cremophor EL, Capryol 90, Labrafac PG) were optimized by solubility assay and pseudo-ternary phase diagram analysis. The liquid SEDDS was mixed with adsorbent (silicon dioxide), glyceryl behenate, pregelatinized starch, sodium starch glycolate, and microcrystalline cellulose and transformed into pellets by the extrusion/spheronization technique.

Formulation and efficacy of triamcinolone acetonide mouthwash for treating oral lichen planus.

Purpose: The stability of a triamcinolone acetonide mouthwash and its efficacy in treating oral lichen planus are described.

Methods: The solubility of triamcinolone acetonide in ethanol, propylene glycol, and glycerin was determined by shaking and equilibrating an excess of triamcinolone acetonide with the solvents for 72 hours. All three solvents were used in formulating a mouthwash.
