Description

Transparent stick-type cosmetic composition with no sweating and little residual feeling

The present invention relates to a stick-type cosmetic composition, and more particularly, there is no sweating at high temperature, and there is little residual feeling upon application, so consumers who are reluctant to use a slippery feeling can use it without any objection. This little relates to a transparent stick-type cosmetic composition.

As we enter the aging era, most people have become more interested in health and happiness, and are investing a lot of time and money in beauty care as they are interested in skin, a measure of beauty, especially while paying attention to appearance. However, there is a practical problem that the condition of the skin cannot improve as the amount of outdoor activity increases. Therefore, cosmetics such as anti-aging, anti-wrinkle, and sunscreen related to outdoor activities have become necessities in the modern beauty industry, and stick-type products made for easy portability have become popular products receiving a lot of attention.

The stick-type cosmetic composition is applied directly to the required area without the process of applying it to the hand, so it does not require post-treatment such as washing hands after application like in general cosmetics, so it has become a very popular product. However, the biggest disadvantage of the stick-type cosmetic composition is that oil leaks to the surface of the container and not only deteriorates the feeling of use, but also has a perspiration phenomenon that deteriorates the appearance.

Several methods have been proposed to solve this problem. For example, it is a principle of lowering the free energy of the oil in the stick-type cosmetic composition by adding wax to increase the hardness. However, this method causes another disadvantage: the feeling of use becomes stiff due to the wax and the product becomes opaque.

Another method is to additionally mix wax with a low melting point, but it is difficult to see it as an innovative solution in that it is still only finding a midpoint between the two properties of perspiration and feeling of use. In addition, a method for improving both the sweating phenomenon and the feeling of use by mixing porous silica powder having excellent oil absorption has been proposed, but in this case, the internal bonding force is weakened, which has a disadvantage in that the stick-type cosmetic composition is broken during use.

The present invention has been devised to solve the above problems, and an object of the present invention is that sweating does not occur even at high temperatures, and there is little residual feeling when applied, so consumers who are reluctant to use a slippery feeling can use it without any hesitation, An object of the present invention is to provide a transparent stick-type cosmetic composition without perspiration and less residual feeling.

The transparent stick-type cosmetic composition of the present invention contains 15 to 30 parts by weight of dextrin palmitate, 5 to 20 parts by weight of propylene glycol dicaprylate/dicaprate, 10 to 20 parts by weight of silicone oil, and amino acid gelling agent 3 to 5 parts by weight, and 40 to 60 parts by weight of hydrocarbon-based oil.

Preferably, the silicone oil is composed of a volatile silicone oil and a non-volatile silicone oil, and the volatile silicone oil is cyclopentasiloxane or a silicone oil in which cyclopentasiloxane and cyclohexasiloxane are mixed, and is a non-volatile silicone oil. is dimethicone having a viscosity of 5 to 20 CS.

Preferably, the amino acid-based gelling agent consists of dibutylethylhexanoylglutamide and dibutyllauroylglutamide.

Preferably, the hydrocarbon-based oil uses octyldodecanol.

The transparent stick-type cosmetic composition of the present invention is formulated by mixing dextrin palmitate, propylene glycol dicaprylate/dicaprate, silicone oil, and an amino acid-based gelling agent. , transparent appearance, etc., so consumers who are reluctant to use a slippery feeling can use it without any objection.

Hereinafter, the present invention will be described in detail.

The transparent stick-type cosmetic composition without perspiration and less residual feeling of the present invention contains 15 to 30 parts by weight of dextrin palmitate, 5 to 20 parts by weight of propylene glycol dicaprylate/dicaprate, based on the total weight of the cosmetic composition, 10 to 20 parts by weight of a silicone oil, 3 to 5 parts by weight of an amino acid-based gelling agent, and 40 to 60 parts by weight of a hydrocarbon-based oil.

The dextrin palmitate of the present invention is synthesized by reacting dextrin with acyl chloride, and by dissolving it with the oil at a high temperature, the oil can be gelled. As the length of the straight-chain fatty acid group of the acyl group constituting the acyl chloride is longer, an oil gel with higher hardness can be obtained when the same amount of dextrin palmitate is dissolved. Dextrin palmitate is contained in an amount of 15 to 30 parts by weight based on the total weight of the cosmetic composition. If it is less than 15 parts by weight, it is insufficient to gel the oil, and if it exceeds 30 parts by weight, it may cause a decrease in feeling of use due to high hardness.

Propylene glycol dicaprylate/dicaprate of the present invention is synthesized by esterification reaction of a mixture of propylene glycol, caprylic acid and capric acid. When applied to , a small residual feeling can be given. Propylene glycol dicaprylate/dicaprate is contained in an amount of 5 to 20 parts by weight based on the total weight of the cosmetic composition. If it is less than 5 parts by weight, it is insufficient to realize a small residual feeling, and if it exceeds 20 parts by weight, the decrease in residual feeling is not large compared to the increased content, so it is inefficient.

The silicone oil of the present invention uses a volatile silicone oil and a non-volatile silicone oil at the same time. In particular, as the volatile silicone oil, cyclopentasiloxane alone or a silicone oil in which cyclopentasiloxane and cyclohexasiloxane are mixed, and as the non-volatile silicone oil, dimethicone having a viscosity of 5 to 20CS is used. desirable. Even if the volatile silicone oil is discharged to the surface, it volatilizes immediately to eliminate sweating, and the non-volatile silicone oil forms an elastic network in the stick-type cosmetic to converge the volume increase caused by the temperature rise. The silicone oil is contained in an amount of 10 to 20 parts by weight based on the total weight of the cosmetic composition. If it is less than 10 parts by weight, it is insufficient to suppress perspiration and form a network, and if it exceeds 20 parts by weight, the possibility of vaporization of the composition increases in the manufacturing process, thereby lowering the total yield.

The amino acid-based gelling agent of the present invention uses an alkylglutamide-based surfactant. In particular, it is preferable to use dibutylethylhexanoylglutamide and dibutyllauroylglutamide. Such an alkylglutamide-based surfactant becomes a colorless and transparent liquid when mixed with an oil component at a high temperature, and becomes a transparent stick-type cosmetic when cooled as it is. The amino acid-based gelling agent is contained in an amount of 3 to 5 parts by weight based on the total weight of the cosmetic composition. If it is less than 3 parts by weight, it is insufficient to gel the oil, and if it exceeds 5 parts by weight, it may cause a decrease in feeling of use due to high hardness.

As the hydrocarbon-based oil of the present invention, any conventionally used hydrocarbon-based oil may be used. In particular, it is preferable to use octyldodecanol. The hydrocarbon-based oil preferably contains about 40 to 60 parts by weight based on the total weight of the cosmetic composition.

On the other hand, the transparent stick-type cosmetic composition without perspiration and less residual feeling of the present invention contains dextrin palmitate, propylene glycol dicaprylate/dicaprate, silicone oil, amino acid-based gelling agent, and hydrocarbon-based oil at 120 ° C. It is prepared through the step of heating and stirring until it is defoamed, then filling it in a stick-type cosmetic container and then cooling it at room temperature.

The gelling agent consisting of dextrin palmitate and an amino acid-based gelling agent used as one active ingredient of the present invention showed a more excellent effect in inhibiting perspiration compared to the case of using each single gelling agent. In addition, the present invention may further blend common ingredients used according to the purpose of the user in addition to the above-mentioned ingredients. For example, waxes, oils, surfactants, pigments, pigments, preservatives, sunscreens, polymers, higher alcohols, fragrances, and the like can be used.
