Yes, sodium hydroxide (the modern term for the archaic "caustic soda") is a base (not quite the same as an alkali, but close and much more clearly defined).
caustic
The most commonly used alkalis in washing powder are caustic soda and caustic potash. They are chemically produced by running electricity through salt water.
Sodium Hydroxide, also called caustic soda or lye.
Depending on the specific hydroxide; for example, hydroxides of the alkali metals are very caustic and dangerous.
Muriatic acid (known also as hydrochloric acid) is neutralized by titration (mixing) with an alkali. Easily obtained alkalis are caustic soda, caustic potash etc. You can see the need for care when handling these strong corrosive chemicals.
caustic
Caustic is a general term for a corrosive alkali. It can be a noun or adjective.
yes it is .A strong one I might add
If the questioner means caustic soda, the answer is no under normal conditions; it is an alkali instead.

Soap is a salt of fatty acids derived from plant/animal oils/fats and metallic alkalis. Water is needed to dissolve alkali, so that the reaction can take place. Therefore the basic soap-making ingredients are: Plant/animal oIls and/or fats Strong alkali (caustic potash - KOH, caustic soda - NaOH) - needed for Water (distilled preferably)
The mixture of Chlor and hydrxide (alkali, OH- from caustic soda, lye, NaOH) reacts to formation of NaOCl and NaCl. Cl2 + 2OH- --> OCl- + Cl- + H2O This is probably what is meant by 'chlor-alkali', nothing else than bleach (3-6% sodium hypochlorite (NaClO))
Soda ash; caustic soda, caustic potash, etc., One of a class of caustic bases, such as soda, potash, ammonia, and lithia, whose distinguishing peculiarities are solubility in alcohol and water, uniting with oils and fats to form soap, neutralizing and forming salts with acids, turning to brown several vegetable yellows, and changing reddened litmus to blue.
