Maliwal launched the protest at Rajghat on Friday in wake of the rape incidents in Uttar Pradesh's Unnao and Jammu and Kashmir's Kathua districts.
In a letter to Prime Minister Narendra Modi on Thursday, the DCW chief said: "I will not break my anshan (fast) until the Prime Minister does not (promise) the country a better system for the safety of our daughters."
The protest saw a large number of women and children participating, urging the authorities to implement stricter anti-rape laws in the country.
The Commission had observed a month-long satyagraha in February demanding fast-track courts and stricter laws for those accused of raping minors.
