Increasing the amount of phenol in the solution
phenol
phenol is aromatic compound stabilized by resonance where as ethanol is aliphatic
with water ethanol is soluble while methane is in soluble

"Ethanol can increase the volume of the polar pathway of the skin, thereby creating new pores, or expand the existing ones to result in increased permeability of the strateum corneum layer. Thus, ethanol-based products may be suspect to problems wherein the ethanol expands the pores allowing bacteria or dangerous chemicals to seep into the skin. Additionally, ethanol can dry the skin. Appropriate gloves should be worn and changed frequently enough to inhibit harmful chemicals or bacteria from penetrating into the skin via an ethanol medium."Excerpt from A Comparison of Commonly Used Surface DisinfectantsAlcohol-, Phenol-, Chlorine-, and Quaternary Amine-Based Disinfectants
Ethanol is known to have a lower absorbance, in comparison to high temperatures, and this is base on ethanol chemical structure.

Phenol solution, or phenol directly from the manufacturer?If the phenol is in the form it comes in from the factory, no chemical test is necessary. Phenol is a white crystalline solid.If it's dissolved in water, the easiest test is pH. Phenol solution is more acidic than ethanol. So...whatever you use for a pH test will do ya.

Yes , phenol is more polar than toluene. because ph-OH has more dipole moment than Ph-CH3
Reactivity in general between the two is quite difficult to compare since the aromatic ring of phenol is able to undergo reactions which ethanol isn't and vice versa. However, there are a number of reactions which can be compared. The first of these is deprotonation, affecting the acidity of the alcohol. Since the subsequent negative charge on the oxygen is stabilised over the benzene ring, phenol is significantly more acid than ethanol (about 100,000 times). Nuclephilic substitution with the alcohol as the nucleophile is likely to be slightly quicker using phenol due to this easier deprotonation creating a stronger nucleophile than the ethanol. Another common reaction is nucleophilic substitution with the alcohol as the electrophile, which occurs fairly easily to ethanol in the presence of an acid. Phenol however, due to its ring, cannot easily react in the same way.

phenol is more acidic because of the benzene ring present in the molecule,when you lose the H form the OH group it is possible to delocalise the charge around the aromatic system due to the pi electron cloud,straight chain alcohols cannot do this so it is less favourable to deprotonate them hance it is easier to deprotonate a phenol,hence we say it is more acidic
1-Phenol (carbolic acid) is acidic in nature and turns blue litmus red while alcohol (ethanol) does not, 2-phenol gives violet or blue colour with neutral ferric chloride solution while alcohol does not, 3-phenol freezes to a solid in fridge while alcohol does not, 4-phenol produces bubbles on rough iron surface while alcohol does not.
"absorbance"Since in the experiment, you probably choose the wavelength, then measure the absorbance (absorption?, the absorbance is the dependent variable.
