Benefits of technology

[0008] The present invention relates to a hair cleansing composition which has, for example, excellent effects for preventing or repairing damaged hair.
[0009] The present inventors have found that a hair cleansing composition incorporated with both an amphipathic amide lipid and a silicone as a protecting base can protect hair from physical and chemical stimulation and thereby preventing spilt ends and breakage of hair, and in addition, can significantly impart hair with a pleasant feeling to the touch such-as natural smoothness, moist feeling, and suppleness which healthy hair inherently possesses.

Problems solved by technology

Since hair is always daily exposed to physical stimulation by daily hair care routines such as heat drying with a hair dryer and brushing, and chemical stimulation by shampooing, permanent weaving, dyeing and bleaching, it is in a damaged state with a partial loss of component or structure.
A change in hair quality due to ageing accelerates this damage and also causes the loss of suppleness which healthy hair inherently possesses.
The composition however cannot contain a sufficient amount of a protecting base such as a ceramide or glycoceramide because it has a high melting point and is liable to crystallize.
Even by such a composition, sufficient hair protecting or repairing effects cannot be attained yet.

[0057] Shampoos as-shown in Table 1 were prepared in the conventional manner and they were evaluated.

[0058] (1) Smoothness and Moist Feeling

[0059] A bundle of 20 g (15 cm in length) of the hair of a healthy Japanese female was made and 1 g of the shampoo in Table 1 was applied to the hair bundle. After one minute of foaming, the hair was rinsed with running water for 30 seconds, followed by towel drying and then drying with a hair dryer. The "smoothness" and "moist feeling" of the dried hair were organoleptically evaluated in accordance with the following criteria:

[0060] Smoothness:

[0061] A: The hair is imparted with natural and sufficient smoothness.

[0062] B: The hair is imparted with smoothness.

[0063] C: It is difficult to evaluate whether the hair is imparted with smoothness or not.

[0064] D: Friction appears among individual hairs.

[0065] Moist Feeling:

[0066] A: The hair became very moist to the touch.

[0067] B: The hair became moist to the touch.

Abstract

Provided is a hair cleansing composition containing (A) an amphipathic amide lipid, (B) an anionic surfactant and (C) a silicone. The hair cleansing composition of the present invention has advantages such as protecting hair from physical or chemical stimulation and preventing split ends or hair breakage~without impairing its cleansing ability and,feeling upon use, and moreover, gives to hair after shampooing a pleasant feeling to the touch and moisture retention properties such as natural smoothness, moist feeling, and suppleness which healthy hair inherently possesses, and has excellent stability.

Description

[0001] The present invention relates to hair cleansing compositions containing an amphipathic amide lipid.BACKGROUND OF THE INVNETION[0002] Since hair is always daily exposed to physical stimulation by daily hair care routines such as heat drying with a hair dryer and brushing, and chemical stimulation by shampooing, permanent weaving, dyeing and bleaching, it is in a damaged state with a partial loss of component or structure. A change in hair quality due to ageing accelerates this damage and also causes the loss of suppleness which healthy hair inherently possesses.[0003] It is a common practice to protect or repair hair in a damaged state by making up for the lost component or structure or analogue thereof. Interaction (affinity) between a protecting base and hair is considered to be important for developing a protecting or restoring function, and thus a method of using sphingolipid or protein derivative as a protecting base has been employed widely as a useful technique. For exa...
