Detergent

A detergent, which is prepared by blending:

• (A) at least one selected from the group consisting of an alkyl sultaine, an alkyl hydroxysultaine, and a nonionic surfactant, and
• (B) an aminopolyether-modified silicone containing a polyoxyalkylene structure and satisfying the following formula (I):
• 0.01≤Si/AO≤1.6 (I)
• wherein Si represents a molar number of a silicon atom in the component (B), and AO represents an oxyalkylene average addition molar number in the component (B),
• wherein a mass ratio [(A)/(B)] of the component (A) to the component (B) is 0.1 or more and 1,000 or less.

A detergent, comprising or prepared by blending:

• (A) at least one selected from the group consisting of an alkyl sultaine, an alkyl hydroxysultaine, and a nonionic surfactant, and
• (B) an aminopolyether-modified silicone satisfying the following formula (I)
• 0.5≤Si/AO≤1.2 (I)
• and comprising a polyoxyalkylene structure having a repeating unit represented by the general formula (2):
• wherein:
• in the formula (I), Si represents a molar number of a silicon atom in the component (B), and AO represents an oxyalkylene average addition molar number in the component (B),
• in the formula (2), a represents a number of 2 or more and 100 or less;
• b represents a number of 1 or more and 50 or less;
• c represents a number of 10 or more and 18 or less;
• d represents a number of 1 or more and 100 or less;
• and bonding order among structural units within the bracket does not matter, and bonding form may be a block form or a random form, wherein the structural units within the bracket are
• and —O(CH2CH2O)—,
• a content or blending amount of the component (A) is 1 to 30% by mass relative to a total mass of the detergent,
• a kinematic viscosity at 25° C. of the component (B) is 500 to 1,500 mm2/s, and
• a mass ratio [(A)/(B)] of the component (A) to the component (B) is 2 to 1,000.
