Abstract

PURPOSE:The titled composition that is made by using a substance generating heat by contacting with water to raise temperatures, a cationic surfactant and an amphoteric surfactant, thus giving moderate warm feeling and showing extensibility with mild foaming on application. CONSTITUTION:The titled composition contains, as essential components, a substance that generates heat by contacting with water to raise temperatures such as polyethylene glycol or 1,3-butylene glycol (in an amount of more than 50, preferably more than 60wt% based on the hair conditioner), a cationic surfactant and an amphoteric surfactant such as lauryl dimethyl betain (in an amount of 0.1-5, preferably 0.3-2.5%). The resultant composition may additionally contain a skin stimulant such as comphor or menthol to give both warm and refresh feelings. The above essential components may contain fatty acid esters or polyethylene glycol additionally to get good extensibility.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to hair conditioning compositions. More specifically, the present invention relates to a hair conditioning composition that has an appropriate warming sensation when used, and that spreads easily due to mild foaming properties.

The present inventors have proposed a new type of hair conditioning agent that does not generate heat during use and has excellent finishing effects even when water is used. (Unexamined Japanese Patent Publication No. 56-5711) However,
Since this exothermic hair conditioning agent contains a large amount of exothermic component, it has the drawbacks of low foaming properties, low slimy feeling, and poor so-called "spreadability" during use. Water-soluble hair conditioning agents also do not spread well.

Against this background, the present inventors have conducted intensive studies with the aim of imparting a smooth and slimy feel to hair conditioning agents, particularly exothermic hair conditioning agents, and have discovered a variety of substances. It has been found that this objective can be easily achieved by incorporating into an exothermic conditioning agent. The present invention is based on this finding, and resides in a hair conditioning composition characterized by containing as essential ingredients a substance that generates heat and increases temperature when in contact with water, a cationic surfactant, and an amphoteric surfactant. . The present invention will be explained in detail below.

The hair conditioning composition of the present invention contains a cationic surfactant, which is generally used as a hair conditioning ingredient, as a main ingredient, and contains fragrances, humectants, anti-inflammatory agents, proteins and their derivatives, animal and plant extracts, and thickeners. It is a conventionally known product containing subcomponents such as a metal sequestering agent and a metal sequestering agent.

Those with a temperature increase of 3° C. or more, preferably 5° C. or more, more preferably 8° C. or more when mixed in the same proportion are used. In addition, safety considerations must be taken when using substances with a temperature of 20°C or above and (K30"C or above). Specific examples of such pyrogenic substances include C3 to C4 alcohols such as ethanol and isopropyl alcohol. alkylene glycols of 02~. such as ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, aliphatic triols such as glycerol,
Dialkylene glycols such as diethylene glycol, dipropylene glycol, diethylene glycol, monomethyl ether, diethylene glycol, monoethyl ether, dialkylene glycol derivatives containing C3-4 alkylene, polyethylene glycols, polypropylene glycols, ethylene oxide and Butyl monoethers of block or random copolymers with propylene oxide or copolymers of ethylene oxide and propylene oxide, poly(ethylene oxide), glycerol adducts of poly(ethylene oxide-propylene oxide), poly(propylene oxide) -C,%, as a glycerol adduct of
Examples include poly(alkylene oxide) containing an ether. Among these, polyethylene glycol, polyoxyethylene polyoxypropylene alkyl ether, flopylene glycol dipropylene glycol, 1
, 3-butylene glycol, and hexylene glycol are commonly used.

The amount of pyrogen used in the hair conditioning agent is usually 50 weight or more, preferably 60 weight or more. If too much is used, the proportion of the hair conditioning base will be reduced, so it is usually 98 weight or less, preferably 95 weight or less.

Furthermore, if a skin irritant is used together with the pyrogenic substance, the skin irritation effect will appear after an appropriate time lag after the exothermic effect. Moreover, by linking both heat generation and skin irritation, unexpectedly excellent warm sensations and refreshing sensations can be obtained. These skin irritants include camphor, menthol,
Conventionally known scalp stimulants such as cantharis tincture, ginger tincture, and capsicum tincture are local irritants, and hair conditioning agents contain 0.01 to 3.
0% by weight, preferably 0.03-2.0% by weight is used.

Next, as amphoteric surfactants, there are conventionally known ones,
Amino acid-type amphoteric surfactants and betaine-type amphoteric surfactants are common; specifically, lauryl dimethyl betaine, (coconut) alkylamides, dobropyl betaine, β-
Examples include sodium lauryl aminopropionate, betaine lauryl dimethyl acetate, and mono- or cina-7um N-lauryl-β-iminodipropionate salt. Amphoteric surfactants are commonly found in hair conditioning agents.
0.1 to 5% by weight, preferably 0.3 to 2.5% by weight are used.

The exothermic hair conditioning composition of the present invention generates heat due to the hydration reaction during use, so it exhibits a mild blood circulation promoting effect. It gives a voluminous feel and a slimy feel, and provides good spreadability. In addition, the pyrogenic substance also acts as a humectant, so it has a good moisturizing effect.

When the hair conditioning composition of the present invention contains a superfatting agent, particularly preferably a superfatting agent that is compatible with a pyrogenic component, the compatibility system of this oily substance is destroyed during use and hydration, and this causes separation and independence. As a result, adsorption or adhesion properties are significantly improved. As a result, the water wash resistance of the hair is improved and an excellent conditioning effect is provided. In addition, as the superfatting agent is destroyed during hydration, the separated superfatting agent floats to the surface of the water.
By lowering the surface tension of cationic and amphoteric surfactants, the active agents are rendered self-diffusive. As a result, due to the self-thinning and self-extensibility of the superfat agent component, a uniform and moderate conditioning effect can be obtained.

That is, stickiness due to over-conditioning is eliminated.

Superfatting agents include fatty acid esters, higher alcohols,
Polyoxyethylene (E, 0.1-6) furkyl ethers, polyethylene glycol (E, 0.1-6) fatty acid esters, polypropylene glycol, polyoxypropylene glycol ether, oils and fats, hydrocarbons,
Hydrophobic silicone oil, polyoxyethylene (E, 0.1
~6) Selected from polyoxypropylene (p, o, 1-6) alkyl ethers, polyoxyethylene castor oil or hydrogenated castor oil derivatives, and polyether-modified silicone oil, <41.0-15% by weight (hair conditioning agent) medium) is used.

Next, the present invention will be explained in more detail with reference to Examples.

Example 1 40g of polyethylene glycol 300, 15.0g of polyethylene glycol 400, and 30.0g of dipropylene glycol. 0.8 g of Of1 and hydroxypropyl cellulose were mixed and heated to 75 to 80°C to uniformly dissolve. To this was added 2.59 g of stearyltrimethylammonium chloride (63% ethyl alcohol) and 1.0 g of cetyl lactate, and after uniformly dissolving the mixture, cooling was started, and then 3 g of isopropyl myristate was added.
．． OF, 5.0 g of hexyldecanol, and 2.09 g of 2-alkyl-N-carboxylmethyl-N-hydroxyethylimidazonium betaine (70% ethyl alcohol) were added and dissolved, and the mixture was cooled to 45° C. or below.

The hair conditioning agent obtained in this way was evaluated for adsorption to the hair, and it was found to be 3 to 5 times more adsorbent than a commercially available hair conditioner that can be applied directly. The antistatic property and combability were also good. In particular, the hair had natural settling properties and was not sticky. Furthermore, in comparison with cream-type commercially available treatment agents, significant differences were observed in terms of non-stickiness, moistness, suppleness, and ease of spreading.
