Abstract

PROBLEM TO BE SOLVED: To obtain a cleaner composition scarcely giving irritancy such as tingling pain or pricking pain even for persons having inherently sensitive skin, that declined in pH buffering function or that declined in prophylactic function due to aging or other factor(s), affording refreshing finish washing and having good usability as well. SOLUTION: This cleaner composition is obtained by including marine collagen, 10-18C fatty acid(s), L-arginine and a strong base. The cleaner composition thus obtained mitigates irritancy such as tingling pain or pricking pain, affording refreshing finish washing with no unpleasant feeling such as dry-and-rough feeling or tense feeling, and also having good usability including foamability and foam sustainability. It is preferable that the content of a fatty acid soap neutralized with the L-arginine in this composition is 1-50 wt.% based on the content of the total fatty acid soap in this composition.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a skin having a reduced pH buffering capacity, a skin having a decreased defense function due to aging, etc., and a skin which is originally sensitive to irritation, and the like, the irritation sensation such as tingling and tingling is extremely small. The present invention relates to a detergent composition which is thoroughly washed without giving an uncomfortable feeling such as a feeling of bulkiness and a feeling of tightness, and is excellent in usability such as foaming and foam retention.

[0002]

2. Description of the Related Art Skin with reduced pH buffering ability, and skin with reduced defense function due to skin aging and other causes are apt to be sensitive to stimuli, including those which are originally sensitive to stimuli. When the cleansing composition is used on the skin, unpleasant stimuli such as tingling and tingling, which cannot be felt when used on healthy skin, tend to be felt sensitively.

In recent years, the safety of the raw material itself for the detergent composition has been rapidly improved by the improvement of the technique for improving the degree of purification of the raw material. However, the tingling sensation such as tingling and tingling may be caused by the pH of the composition, or even the preservatives, chelating agents, surfactants, organic acids, fragrances, and even ethanol, which are essential components of the detergent composition. It is known to be a cause of this, and consumers with sensitive skin as described above are often accompanied by an unpleasant sensation when using a conventional detergent composition.

Conventionally, anionic surfactants such as alkyl sulfate ester salts, polyoxyethylene alkyl ether sulfates, and fatty acid soaps, which have high foaming power and detergency, have been widely used as skin cleansing agents. However, when an alkyl sulfate ester salt or polyoxyethylene alkyl ether sulfate salt is used as a surfactant, there may be a problem in skin irritation and eye mucous membrane irritation, and fatty acid soap is alkaline. It is said that after washing, the skin feels bulky and taut, and that the burden on the skin during washing is heavy. Therefore, in order to use it for consumers with sensitive skin, use a surfactant with low skin irritation and skin sensitization to reduce skin irritation as much as possible, or use a low amount of surfactant. It has been difficult to provide a cleaning composition that can be safely used by consumers with sensitive skin due to restrictions such as the need to suppress it.

Recently, there is a tendency that a weakly acidic skin cleansing agent containing N-acyl amino acid salt or the like as a surfactant and having a pH close to the skin surface is preferred. For consumers who are characterized by a high moist feeling, and who prefer a refreshing feeling over a moist feeling, a cleansing and cleansing detergent composition that does not irritate the skin has been desired.

[0006]

Therefore, in the present invention, the problems of the conventional detergent compositions as described above are solved, and the person who is originally sensitive to the skin or the skin has a protective function for some reason. It is hypoallergenic to people in a weakened state,
Moreover, it was intended to obtain a detergent composition having a sufficient washing function with a clean washing.

[0007]

[Means for Solving the Problems] As a result of intensive studies to solve the above problems, a cleaning agent containing marine collagen, a fatty acid having 10 to 18 carbon atoms, L-arginine, and a strong base. It has been found that the composition alleviates tingling sensations such as tingling and tingling, and cleans up cleanly without giving an unpleasant feeling such as a feeling of dryness and tightness, and is also excellent in usability such as lathering and foam retention. The present invention has been completed.

That is, the present invention relates to marine collagen,
The present invention relates to a detergent composition containing a fatty acid having 10 to 18 carbon atoms, L-arginine, and a strong base.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below.

The marine collagen used in the present invention can be extracted from various sites of marine organisms, and is not particularly limited, but includes bones of fish (eg, cod, flounder, salmon, sardines, tuna, etc.), It is extracted from tissues such as skin, tendon, and bladder using a known method.

In addition, the above-mentioned collagen is added with acid, alkali,
Hydrolyzate obtained by hydrolysis with an enzyme or a combination thereof, succinylation product, alkyl or alkenyl ester such as ethyl ester and hexadecyl ester of the hydrolyzate, alanine myristic acid condensate of the hydrolyzate, isostearic acid Condensates of fatty acids such as condensates, coconut oil fatty acid condensates, undecylenic acid condensates, resin acid condensates and salts thereof;
Cationized modifications such as chloro-2-hydroxypropyltrimethylammonium chloride adduct, glycine trimethylammonium chloride adduct and salts thereof, addition modifications such as 3-glycidoxypropylmethyldihydroxysilane adduct of the hydrolyzate, and them The salt and the like can also be preferably used.

The above-mentioned marine collagen is more excellent in moisturizing effect and safety than animal collagen.

The content of marine collagen in the detergent composition of the present invention is, considering its effectiveness and usability,
0.00001 to 0.
1 wt% is preferable, and 0.0001 to 0.08 wt% is more preferable. When the content of marine collagen is less than 0.00001% by weight based on the whole, tingling sensation,
It becomes difficult to exert a sufficient effect of alleviating a tingling sensation such as a tingling sensation, and conversely, when it exceeds 0.1% by weight, usability is lowered, which is not preferable.

In the present invention, a fatty acid having 10 to 18 carbon atoms is used. Specific examples thereof include capric acid, lauric acid, coconut oil fatty acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid and oleic acid.

These fatty acids are neutralized with L-arginine and a strong base to be used as a fatty acid soap which is a kind of surfactant.

The content of L-arginine used in the present invention is preferably 0.001 to 5% by weight, more preferably 0.01 to 3% by weight, based on the whole composition, in consideration of effectiveness and usability. preferable. When the content of L-arginine is less than 0.001% by weight with respect to the entire composition, it becomes difficult to exert a sufficient effect of alleviating the tingling sensation such as tingling and tingling sensations, and conversely exceeds 5% by weight. And the smell peculiar to arginine is worrisome, which is not preferable.

Further, in the present invention, in terms of product stability,
For the reason of usability, a strong base such as sodium hydroxide or potassium hydroxide is contained in addition to L-arginine.

The neutralization ratio of fatty acids is preferably 65 to 85%, and the content of fatty acid soap neutralized with L-arginine is 1 to 50 with respect to the content of total fatty acid soap.
It is desirable to be in the range of% by weight. When the content of the fatty acid soap neutralized with L-arginine is less than 1% by weight based on the content of the total fatty acid soap, it becomes difficult to exert a sufficient relaxing effect on the irritating sensation such as tingling sensation and tingling sensation, On the other hand, if it exceeds 50% by weight, it is not preferable that the detergent composition has foaming or foam retention and feels slimy at the time of washing.

The detergent composition of the present invention may further contain other components as long as the effects of the present invention are not impaired. Such components include anionic surfactants other than the above, amphoteric surfactants, nonionic surfactants, cationic surfactants, plant extracts, vitamins, alcohols, polyols, oils, pearlizing agents, moisturizing ingredients, Fragrance, pigment, ultraviolet absorber, antioxidant, bactericide,
Anti-inflammatory agents, antiseptics and the like can be mentioned.

The detergent composition according to the present invention can be provided in the form of cream, paste, liquid or the like.
