Description

  The present invention relates to a shampoo composition that has low skin irritation and excellent detergency.

In general, hair shampoos, which are representative embodiments of hair cleaning compositions, widely use anionic surfactants, especially alkyl sulfates or alcohol alkoxylate sulfates, as cleaning components. However, although shampoos using these anionic surfactants have excellent detergency, they have strong skin irritation and have a problem of roughening the skin when used continuously.

  In contrast, amidoamine-type and amidobetaine-type amphoteric surfactants are known to be extremely mild surfactants with low irritation to skin and ocular mucosa, and are based on amidoamine-type amphoteric surfactants The composition (refer patent document 1) used and the composition (refer patent document 2) which used the amide betaine type | mold amphoteric surfactant as a main component are known. However, these compositions are less irritating to the skin and ocular mucosa, but have poor foam creaminess and are not satisfactory in foaming.

  Accordingly, it is an object of the present invention to provide a shampoo composition that is less irritating to the skin and the like and has a good cleaning power.

  As a result of intensive studies to solve the above problems, the present inventors have found that an excellent shampoo composition can be obtained by specific blending of a specific anionic surfactant. For example, a higher secondary alcohol alkoxylate (I) obtained by addition reaction of an olefin having 8 to 30 carbon atoms with (poly) alkylene glycol as an anionic surfactant, and the higher secondary alcohol alkoxylate (I) Furthermore, secondary alkyl sulfates such as higher secondary alcohol alkoxylate sulfates obtained by sulfation of higher secondary alcohol alkoxylates (II) obtained by reacting with alkylene oxides having 2 to 8 carbon atoms. Is a conditioning comprising at least one compound selected from the group consisting of a non-volatile silicone, a cationic polymer, a cationic surfactant, and an aliphatic alcohol. By using the agent, with low irritation to the skin It found that good and shampoo compositions with excellent conditioning properties of detergency is obtained.

  A shampoo composition with low skin irritation, good detergency and excellent conditioning properties by blending a higher secondary alcohol alkoxylate sulfate containing a specific proportion of secondary alkyl sulfate as a cleaning active ingredient Things are obtained.

  As a result of intensive studies on the shampoo composition, the present inventors have found that a shampoo composition comprising a higher secondary alcohol alkoxylate sulfate having a secondary alkyl sulfate content of 5% by mass or less is excellent. It has been found that the above-mentioned problems can be solved brilliantly by discovering that it exhibits a good cleaning performance and that it is mildly irritating to the skin and the like.

The higher secondary alcohol alkoxylate sulfate as the component (A) of the present invention has the following general formula (1):
General formula (1)

(In the formula, R1 and R2 represent an alkyl group, the total number of carbon atoms is 7 to 29, and R1 ≦ R2, and MO is one or more kinds of oxyalkylene groups having 2 to 8 carbon atoms.
