the main purpose of this project is investigation of the organophosphorus hydrolase (oph) enzyme activity in water in oil (w/o) and oil in water (o/w) creams and investigation of the oph enzyme stability in formulated creams. oph enzyme was extracted and purified from strain flavobacterium. the w/o and o/w creams were prepared using different formulations. in order to achieve an emulsion with m...

BACKGROUND Chronic exposure to mild irritants including cleansing and antiseptic products used for hand hygiene generates insults to the skin. To avoid unpleasant reactions, skin protection creams are commonly employed, but some fail to afford protection against a variety of xenobiotics. In this study, two skin protection creams were assayed comparatively looking for a protective effect if any ...

Skim, sweet buttermilk, and butter-derived aqueous phase components were used to reemulsify low-melt butteroil into creams with a desired 20% milkfat. The implications of pasteurization process, homogenization sequence, and formulation on the physicochemical properties of reformulated and natural creams were investigated. Creams homogenized prior to pasteurization had significantly (p<0.05) gre...

DESIGN 11 herbal creams obtained from patients attending general and paediatric dermatology outpatient clinics were analysed with high resolution gas chromatography and mass spectrometry. SETTING Departments of dermatology and clinical biochemistry. MAIN OUTCOME MEASU...

Sun protection creams were formulated with a commercial rosemary extract and with thermal waters from different springs in the Northwest Spain. A six month stability study was carried out and microbiological and chemical stability, as well as sensorial characteristics, were evaluated. In all creams, the mesophilic count always remained low (under 10 cfu/mL) and most of them showed greater antio...

Trace amounts of potentially toxic metals can be either intentionally added to cosmetics or present as impurities in the raw materials. In the present study, the levels of lead, cadmium, nickel, chromium, and mercury have been assessed in 28 body creams and lotions, 10 powders, 3 soaps, 5 eye make-ups, and 4 lipsticks widely available on Nigerian markets. The increases over suggested or mandate...

Local anesthetic creams for the clinical treatment of conditions such as postherpetic neuralgia were prepared as an in-house formulation from the eutectic mixture of lidocaine-tetracaine (LT cream) using two eutectic mixtures of local anesthetic (EMLA) type bases. The LT formulation was compared with a lidocaine-prilocaine (LP cream) eutectic mixture formulated using the same base as EMLA. The ...

Oleum Hyperici, the oil extract of St. John's Wort (SJW), is one of the oldest folk remedies, traditionally used in the topical treatment of wounds, bruises, ulcers, cuts, burns, hemorrhoids and also as an antiseptic. Considering the advantageous characteristics of emulsion applications, in the present study we have formulated three O/W creams containing 15% (w/v) of SJW oil extract as an activ...
