Svensson A. Allergic contact dermatitis to laureth-4. Contact Dermatitis. 1988 Feb;18(2):113-4. doi: 10.1111/j.1600-0536.1988.tb02759.x.

Friberg SE, Aikens PA. Constant vapor pressure emulsions evaporation: Linalool/water stabilized by Laureth 4. J Colloid Interface Sci. 2009 May 15;333(2):599-604. doi: 10.1016/j.jcis.2009.02.034.

Abstract.  Evaporation paths were calculated in the title system using the relevant part of its published phase diagram and the assumption of equilibrium between vapor and liquids.

Friberg SE, Szymula M, Fei L, Barber J, Al-Bawab A, Aikens PA. Vapour pressure of a fragrance ingredient during evaporation in a simple emulsion. Int J Cosmet Sci. 1997 Dec;19(6):259-70. doi: 10.1046/j.1467-2494.1997.171722.x.

Abstract. The phase diagram water, phenethyl alcohol and laureth 4 was determined and the variation of the vapour pressure of the alcohol was determined during evaporation using gas chromatographic head-space analysis.

 Friberg SE, Al Bawab A. Phase behavior of beta hydroxy-acids with laureth 4. J Pharm Sci. 2006 Aug;95(8):1834-40. doi: 10.1002/jps.20554.

Abstract. The colloidal structures of beta carboxylic acid topical vesicle formulations were determined and the changes during evaporation after applications were estimated from phase diagrams. 

Al-Bawab A. Investigation of the phase behavior and an evaporation study of systems of lavender oil, water, Laureth 4, and Tween 80. J Cosmet Sci. 2003 Sep-Oct;54(5):429-41.

Abstract. Natural essential lavender oil was obtained by steam distillation from the flowering plants. The phase behavior of a system of natural lavender oil, distilled water, and two stabilizers was investigated.

Al-Bawab A, Friberg SE. Phase behavior of the alpha-hydroxyoctanoic acid/Laureth 4/white oil/water system and preliminary evaluation of the phase changes during evaporation of its emulsion. J Cosmet Sci. 2002 May-Jun;53(3):151-64.

Abstract. The phase diagram was determined for the alpha-hydroxyoctanoic acid/Laureth 4/white oil/water system using visual observation with an optical microscope. Typical emulsions were evaporated to determine the structural changes.
