mineral oil hlb

Hlb number 68 results in the formation of a milky emulsion after vigorous agitation while hlb values in the range of 8 to 18 stabilize oil-in-water emulsions hlb number 810 results in the. The ratios of mineral oil and water are needed to specify first in order to know types of emulsifier you would like to get Winsor Type I or II or else.

Each RHLB value of oil components is found from literature.

. 50 X Required HLB 6 30. B Determine the amount of Tween 60 HLB149 and Span 60 47 required to reach this HLB. We used emulsifiers comprised of fatty acid esters of polyoxyethylene sorbitan Tweens or sorbitan Spans to prepare oil-in-water OW emulsions of hexadecane.

A short summary of this paper. See below Before we label our variables we need to determine the mass of mineral oil used in the Rx. 2 calculated ideal RHLB of the oil phase is 1085.

Emulsogen M possesses excellent emulsifying properties for mineral oils. To calculate the required HLB of the Oil Phase we multiply the percentage of each oil in the Oil Phase by its respective required HLB and sum the results. A different RHLB is required to form an oil-in-water wo type emulsion with the same oil phase.

The seleted surfactant andor co-surfactant. Surfactants with hlb values in the range of 4 to 8 usually stabilize water-in-oil emulsions hlb number 46 results in the formation of poor emulsion. Because of the general utility of the HLB system many surfactants that are not ethoxylated or have other water-soluble groups have been added over the years by comparing their emulsification properties to surfactants with known HLBs.

Co-emulsifier for mineral oils. Very stable emulsions of mineral oils are obtained with as little as 10-12 emulsifier calculated on the quantity of oil to be emulsified. Emulsion stability could be predicted from a ratio of spectrophotometric absorbance readings at 800 and 400 nm but not from published hydrophilelipophile balance HLB values.

A specific HLB called. The oil phase is consisted of mineral oil rHLB 11 octyldodecyl myristate RHLB 75 Cetyl alcohol RHLB 155 and propylparaben. The HLB scale ranges from 0 to 20 with 10 corresponding to an emulsifier that is equally attracted to water and oil.

Wetting powders into oils use surfactants with HLBs of 7 to 9 making self emulsifying oils use surfactants with HLBs of 7 to 10 making oil-in-water emulsions use surfactant blends with HLBs of 8 to16 making detergent solutions use surfactants with HLBs of 13 to 15 for solubilizing oils micro-emulsifying into water use surfactant blends with HLBs of 13 to 18. Is required for the oil phase of an oil in water ow type emulsion. So they are more hydrophilic having V higher HLB values ranging from 96 to 167.

In contrast emulsifiers with HLB values less than 10 are more hydrophobic and therefore better suited for wo emulsions. EPA exempted from tolerance under 40 CFR 180. Blodegradable emulsifier for mineral oils.

Based on natural fatty alcohols. HLB values for both emulsions of type ow and wo can be empirically determined for many oils and fats. 37 Full PDFs related to this paper.

Select your oil phase and determine its Required HLB from the table4 Mineral Spirits. Required HLB for OilsLipids Almond Oil required HLB 6 Anhydrous Lanolin USP required HLB 10 Apricot Kernal Oil required HLB 7 Avocado Persea Gratissima Oil required HLB 7 Babassu Oil required HLB 8 Beeswax required HLB 12 Borage Borago Officinalis Seed Oil required HLB 7 Brazil Nut Oil required HLB 8. The length of the alkyl chain influences the CMC and HLB value and these become important considerations when selecting the right chemical-type for your emulsion.

Used along with LAKPOL AO 905. HLB values ranging from 18 to 86. Tweens are polyoxyethylene derivatives of spans.

Necessary hydrophile-lipophilic balance RHLB. Blodegradable emulsifier for mineral oils. Emulsifiers with HLB values greater than 10 are more hydrophilic and thus better at stabilizing ow emulsions.
