There is no chemical formula for milk. It is an emulsion containing several ingredients.
Antiseptic wash usually contains alcohol or benzalkonium chloride or sometimes iodine. You can look these up to get the formulas.

It’s easy easy when u have ur periodic table on hand. For example with magnesium oxide (obviously u should know the symbols if not there’s only one thing to do… learn them)
So we have: Mg and O,
Mg is in the 2nd column and so has a charge of +2
O is in the 2nd last column and so has a charge of -2
So both have the same chare so just combine them: MgO
If we look at water: H is in 1st column so has a +1 charge
O is in 2nd last so has a charge of 2-
so u need 2 H for every 1 O (because the charges need to balance.
so: H2O (the 2 should be a subscript)
all the elements between the 2nd column and the 3rd last column can have varying charges(except for silver, Ag which has a +1 charge), like iron, they normaly tell u what the charge is though like Fe(III) is iron with a 3+ charge, etc.
(Rule of thum: the element with the lower amount of charge gets the higher number after it, in the resulting equation) for an example take a look at water again.
Of course the best way to become quick and efficient in determining the resulting chemical formulas is to practice, practice, practive…
Good Luck

metal in front non metal in behind.
Na Cl = NaCl
KF
Mg2O2 the 2 cancel out
MgO
G1 charge 1
G2 charge2 and so on g7 charge 1 g6 charge 2 g 5 charge 3 g 4 charge 4 g 3 charge 3g8 charge none

do you know how to see what the charge is, look on the periodic table, column 1a all have +1 charge, column 2a has +2 charge, column 3a have +3 charge. Now start from the right side of the table, all the 8a have no charge, the 7a have -1 charge, the 6a have -2 charge, the 5a have -3 charge and the 4a have -4 charge.
Now to get the chemical formula you just make them neutral, Potassium is in 1a so it has a +1 charge Fluorine is in 7a so it has a -1 charge, so they go together at a 1:1 ratio. KFl
Mg is 2+ and Oxygen is 2- so they go together and make a neutral product as well MgO. Now say you got Potassium Oxide. Potassium has 1+ so you need two of those to make the product neutral because Oxygen is 2-. so K2O The 2 should be a subscript of course.

A short cut for wrting sub scrips is to press ctrl and = then just type what you want for super scripts press ctrl shift and =
