Lack of knowledge and/or full consent does not change the object or species of the action. An intrinsically evil act such as adultery is an act that cannot be ordered to good or made good regardless of circumstances, intention, lack of knowledge, or lack of deliberate or full consent. Ignorance or lack of full or deliberate consent which are the subjective factors in the human action can reduce the culpability of the person committing the act but they cannot make an act that is evil in itself, an intrinsically evil act, good. It remains an evil and bad act regardless of the degree of culpability of the person committing it. This is what is meant by an intrinsically evil act in its object or species, it is objectively evil regardless of the subjective conditions of the person. And for a human action to be a good action, the object, circumstances, and intention must all be good. A lack of goodness in one of these three causes the act to be evil. An intrinsically evil act is evil in its object which results in an evil human act even if the circumstances and intention appear to be good.

No, you have perhaps too quickly conflated the
object component of the** human act** with the “
human act” itself.
An actual “human act” has three components: object (matter), subject (intention) and circumstances.
The “intrinsic evil” is clearly predicated of the object (ie the matter). In other words the object is so gravely disordered/evil (malum poenae) that if it is freely intended and understood by the agent (the subject) then the act as a whole becomes a culpable mortal sin, a moral evil (malum culpae).
Now the object by definition abstracts away from issues of consent/knowledge which is in the subject.
Now the matter/object is specified in the Commandments.
Lets take “adultery”.
In English “adultery” is also abstracted from any internal reference to understanding or consenting to the behaviour. If you sleepwalk to your wife’s sister’s bedroom and she is willing then you have still committed adultery even without really knowing or consenting.
So the word “adultery” well describes the matter of a potentially complete “human act”.
Here we have intrinsic object evil (malum poenae).
Next we have to decide whether the actual “adultery” behaviour in question is really a complete “human act”. That is why I just said “potentially”.
This is where “intention” (the subject component of a “human act”) comes into play.
If the object is truly understood and consented to (ie “intended”) adultery then bingo we have a complete human act which must therefore be a mortal sin. We may also call this actual sin an example of intrinsic moral evil, intrinsic moral fault (malum culpae).
BUT, if the agent was sleep-walking then there is no (or little) subjective involvement.
Bingo, venial sin or even no moral fault at all. This is not properly called a “human act”. Subjective engagement through understanding and consent must be present if we are to call any behaviour a “human act.”
Therefore no intrinsic moral evil (no malum culpae) is present here. Of course intrinsic object evil is still present (malum poenae).
I have left out the circumstances component of a complete “human act” for clarity…it changes little of the above analysis.
Now you said “An intrinsically evil act (adultery?) is evil in its object which results in an evil human act …”
This is not always true. Sometimes a “human act” is not present. if it isn’t present there is no intention, either good or bad. In which case the “adultery” is still properly called adultery but it is not “an act” (as in “human act”). Nor can it be called an “intrinsically evil human act.” It can of course be called intrinsically evil “behaviour”, which many people also confusedly also call “an act”. Yet it is not a “human act”.
So I would suggest you really should have said:
“An intrinsically evil behaviour (adultery?) is evil in its object which results in an intrinsically evil human act when full understanding and intent is present…”
