DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention suppresses hair damage,
The present invention relates to a permanent composition which forms a good wave or straight state, gives a moderate moist feeling, excellent flexibility and gloss to hair, and suppresses unpleasant odor.

[0002]

2. Description of the Related Art Conventionally, a permanent wave agent (hereinafter simply referred to as a permanent agent) and its principle are based on a reducing agent such as thioglycolic acid and its salts, cysteine and its derivatives, sulfite, and the like. Ammonia, monoethanolamine, ammonium bicarbonate, an alkali agent such as sodium hydroxide is added, and the first bond of the permanent agent whose pH is adjusted to about 8 to 9.5 reduces and opens the S—S bond in the hair, Next, a method is generally used in which a second permanent agent mainly containing an oxidizing agent such as sodium bromate, hydrogen peroxide, sodium perborate, or the like is used to oxidatively close to create a wave or keep the wave straight. However, during the perm treatment, adverse conditions such as swelling of the hair due to alkali, chemical changes associated with reduction / oxidation, and protein denaturation due to heating are superimposed, resulting in a decrease in SS bonds and the outflow of mesenchymal substances. As a result, defects such as damage to hair, deterioration of moisturizing property, and peeling of cuticles, resulting in deterioration in feel and gloss were observed. Further, during the treatment, there was an unpleasant odor of the perm agent itself and an unpleasant odor generated when the hair reacted with the perm agent, which was painful for the practitioner and the practitioner. Various attempts have been proposed to solve these problems. For example, silicones have been added to impart gloss and oiliness to hair, and protein hydrolyzates have been added to perm agents to prevent damage and dryness. In addition, masking with a fragrance is generally performed for an unpleasant odor.

[0003]

However, when a large amount of silicones is used, oily smears when wet and fly hairs when dry are caused, and the problem of stickiness and damaged hair is effectively absorbed. not,
In some cases, moist feeling cannot be imparted. Similarly, although the protein hydrolyzate is useful for preventing damage to some extent, its effect is not sufficiently satisfactory, and when used in a large amount, there has been a problem that a decrease in wave power and an increase in unpleasant odor are observed. At present, satisfactory results have not been obtained by masking with a fragrance alone for unpleasant odors such as hydrogen sulfide and methyl mercaptan generated by the reaction between the hair and the perm agent during the perm treatment.

Accordingly, an object of the present invention is to form a good wave or straight state while suppressing damage to the hair, and to give the hair a moderate moist feeling, excellent flexibility and luster, and an unpleasant odor. An object of the present invention is to provide a permanent composition which suppresses the perm.

[0005]

Means for Solving the Problems The present inventor has conducted intensive studies in view of the above-mentioned circumstances, and as a result, by combining a specific oil component, a seaweed extract and vitamins with a perm agent, hair damage is suppressed, The present invention has been found to form a good wave or straight state, to give a moderate moist feeling, excellent flexibility and luster to hair, and to suppress unpleasant odor, thereby completing the present invention.

That is, the present invention provides the following component (A):
(B), (C) and (D): (A) one or more vegetable oils and fats (B) one of oil components selected from hydrocarbons having 15 or more carbon atoms

Particularly effective is vegetable squalane. The compounding amount is 0.05 to 20% by weight, preferably 0.5 to 15% by weight based on the total amount of the composition. If it is less than 0.05% by weight, the effect of preventing hair damage is low, and if it is more than 20% by weight, the effect of the main agent is reduced, and good wave and straightening effects cannot be obtained.

The total amount of the components (A) and (B) is preferably 1 to 20% by weight of the whole.
If the amount is less than 1% by weight, a moderately moist feeling cannot be obtained and 2
If it exceeds 0% by weight, the stability of the product is impaired and the hair becomes sticky.

The seaweed extract of the component (C) is a brown algae (Ph
aeophyta), red algae (Rhodophyta)
And substances extracted from all algae of green algae (Chlorophyta) with water or a solvent such as alcohol or 1,3-butylene glycol, and is mainly composed of natural polysaccharides such as alginic acid and carrageenan and derivatives thereof. The compounding amount is 0.01 to 5% by weight, preferably 0.05 to 3% by weight, based on the total amount of the composition. If it is less than 0.01% by weight, the effect of preventing hair damage and moisture retention are low,
If it exceeds 5% by weight, the touch will be worse.

The vitamins of the component (D) can be broadly classified into fat-soluble vitamins such as vitamins A, D, E, and K and water-soluble vitamins such as vitamins B and C. Derivatives such as ester forms exist for each. Among them, vitamins A and E, which are fat-soluble vitamins, and derivatives thereof are preferable in that they impart good gloss to hair. Specific examples include vitamin A, such as retinol, retinal, retinoic acid and its derivative, retinol acetate, retinol palmitate, retinoic acid ester, and vitamin E, such as DL-α-tocopherol, D-δ-tocopherol, and acetic acid.
