Abstract:

Hydrophile–lipophile balance (HLB) is a key parameter for formulation of emulsions. Recently, modified coconut oil (MCO) was successfully developed as antimicrobial oil and was attempted to use as active ingredient in emulsions. Therefore, the aim of this study was to determine the required HLB of MCO. The emulsions was produced with different ratios of emulsifier mixtures of Tween® 80 and Span® 80 , giving HLB from 4.3 to 15.0 and was investigated in respect of their emulsions stability. The result showed that an emulsion with HLB value of 12 demonstrated the most stable in terms of smallest

Abstract:

In this paper, emulsification study on bio-oil middle fraction and diesel was carried out. Mechanical and ultrasound emulsification technologies were used to prepare emulsion fuels between bio-oil middle fraction and diesel with different hydrophile and lipophile balance (HLB) values. It was found that the stability curve of emulsions had two peaks corresponding to the HLB values of 4.3 and 6, respectively. Comparable to the mechanical emulsions, the ultrasound emulsions had longer stable time. The stable time for ultrasound emulsions at the HLB values of 4.3 and 6 were 215 minutes and 143 min

Abstract:

Water (W) and oil (O) normally mix during production and while passing through valves and pumps to form a persistent water-in-oil (W/O) emulsion, which is a serious restriction in oil production and transporting and refining processes. The objective of this work is to treat emulsions of two crude oil samples labeled KD1 and DGH2 using commercial polymers and surfactants which are also known as demulsifiers. Hydrophile–lipophile balance (HLB) in the demulsifier structure has demonstrated a great effect on breaking W/O emulsion. Emulsion breakers with low HLB value showed better reduction in the

Abstract:

Experimental study on the physico-chemical properties of bio-oil and diesel emulsification has been carried out in this paper, which was based on the preliminary experiment. The effect of surface tension and viscosity on the stability of emulsions were particular concerned. It was found that the longest stable time, the lowest viscosity and lowest surface tension can be obtained simultaneously when the hydrophile and lipophile balance (HLB) value was of the optimal value, i.e. 6.5. Experimental results indicated that the stable time of emulsion decreased rapidly with the increase of bio-oil co

A series of acrylate latexes for pigment printing binder were prepared by semi-continuous pre-emulsifying emulsion polymerization, using lipophilic glycidyl meth-acrylate (GMA), ethylene glycol dimethyl acrylate (EGDMA) and hydrophilic HA (containing hydroxyl, acylamino), N-methylol acrylamide (NMA) as cross-linking monomer. The influences of cross-linker type on the particle size, viscosity and film-forming rate of latex, cross-linking degree and tensile properties of latex film were studied. It was found that the latex particle size, viscosity and film-forming rate were closely related with

Abstract:

Summary As a type of mono-alkyl ester, biodiesel exhibits great potential to serve as the base oil of drilling fluids substituting for conventional oil-based drilling fluids (OBDFs). This paper presents a series of laboratory investigations of water-in-biodiesel (invert) emulsion as the basis of a high-performance, environmentally friendly, and low-cost biodiesel-based drilling fluid (BBDF). Biodiesel produced from waste cooking oil was used to formulate a BBDF because of its high flashpoint, reliable storage stability, acceptable elastomeric material compatibility, nontoxicity, and excellent

Purpose: To evaluate the rheological, biochemical, hydrophile-lipophile balance (HLB) of Archachatina marginata (snail) mucin extract for possible use as a nutraceutical and nano biopharmaceutical material. Methods: Snail mucin was extracted with acetone and water, lyophilized and the biochemical, proximate and mineral analyses of the extracts were studied using standard methods. The rheological properties of the extracts (1, 2, 4 and 8 % w/v) and their emulsion-based preparations were evaluated. Other physicochemical properties and HLB values of the preparations were also determined.&#x

Abstract:

Methods of formation of emulsions and foams are given; both types of system are stabilized by surfactants. Emulsions can be oil-in-water or water-in-oil type and the preferred type is discussed in terms of the hydrophile–lipophile balance of the system, which ultimately depends on the preferred curvature of close-packed surfactant monolayers at droplet interfaces. Droplet and bubble size distributions in emulsions and foams respectively, evolve with time through Ostwald ripening (bubble disproportionation in foams); larger drops (bubbles) grow at the expense of smaller ones since the Laplace pressure in small bubbles/drops exceeds that in large ones. Creaming occurs in emulsions (if drops are less dense than the medium) and in foams so the volume fraction of dispersed phase, ϕ‎, changes with height. At high ϕ‎ both emulsions and foams assume polyhedral structures giving high internal phase emulsions and ‘dry’ foams, respectively. Methods of breaking unwanted emulsions and foams are described.

Abstract:

According to the hydrophile-lipophile balance (HLB) theory and the evaluation results of friction, wear and lubrication using a four-ball tribometer, a novel oil-in-water emulsion was developed for the hot rolling process of hard brass (single phase alpha-brass, CuZn32 (ASTM C26200) and CuZn30 (ASTM C26000)) by controlling the composition of the emulsion, such as emulsifying, antiwear, extreme pressure, antirust and so on. In the actual hot rolling process, the roller material was the welded-stainless steel ASTM 420 (HRC34-44), in which the lubrication mechanism of brushing grease discontinuou
