Description

Vegetable petrolatum jelly (vaselin) substitute and method for producing the same

The present invention provides a novel oil thickener and manufacturing method for increasing the viscosity of oil, characterized in that it contains only natural ingredients.

The oil thickener itself is sometimes used as an external agent for skin protection or as a cosmetic, and in cosmetics or pharmaceuticals, it is mainly used as a method for imparting formulation stability and maintaining effective active substances on the skin surface for a long time.

Vaseline as a representative oil thickener can be obtained by refining an ointment-like substance obtained by solvent dewaxing of vacuum distillation residual oil of crude oil, and its main component is a hydrocarbon of C24 - C43 and is an amorphous substance. White Vaseline, which has a high degree of purification and can be used for cosmetics or pharmaceuticals, is commercially available.

Vaseline is often used in skin care cosmetics, make-up cosmetics, or pharmaceuticals for external use for the skin to impart formulation stability and to achieve target viscosity and hardness.

However, although Vaseline has an excellent thickening effect, it generally has low hardness, and thus an excessively sticky formulation may be produced, which hinders the implementation of a formulation having low stickiness and appropriate hardness.

In addition, vaseline is a material obtained from the residual oil of vacuum distillation of crude oil and is well known to have a possibility of environmental contamination and to have toxicity unsuitable for application to sensitive skin or wounds.

Therefore, there is a need for an oil thickener capable of imparting a viscosity increasing effect similar to petroleum jelly and a more solid hardness while being environmentally friendly with low skin toxicity and irritation.

The oil refers to a lipid that exists as a liquid at room temperature and atmospheric pressure. Generally, the oil has a viscosity of 0.5 to 300,000 cps, preferably 10 to 100,000 cps, and more preferably 50 to 50,000 cps. Therefore, it was impossible to make a formulation with viscosity and hardness suitable for application to the skin using only oil.

Therefore, a method of obtaining suitable hardness by heating and then cooling with wax is commonly used, but in this case, it is possible to obtain a higher hardness compared to Vaseline, which has a low viscosity and a hard formulation, but obtaining a viscosity similar to that of Vaseline is not possible. It was impossible. In addition, since wax has high crystallinity, liquid oil oozes over time, resulting in unstable formulation and increased hardness.

The oil is physiologically acceptable, specifically, cosmetically acceptable oil, and is particularly naturally derived oil extracted from plants or animals by a conventional method such as pressing, pulverizing, or heating. More specifically, castor oil, sunflower seed oil, avocado oil, olive oil, palm oil, etc. having volatile or non-volatile properties may be included independently or in combination.

The wax means a lipid that exists as a solid at room temperature and atmospheric pressure. It is a physiologically acceptable, specifically cosmetic or pharmaceutically acceptable wax, and may in particular be of mineral, animal, plant or synthetic origin. More specifically, hydrocarbon waxes, silicone waxes, fluoro waxes, and hydrogenated, isomerized, esterified, or hydroxylated forms thereof may be included independently or in combination. For example, lanolin wax, lemon wax, microcrystalline wax, montan wax, beeswax, berry wax, shellac wax, alpha wax, orange wax, ourcury wax, ozokerite wax, sumac wax, chaff wax, Japanese wax , Chinese insect wax, carnauba wax, candelilla wax, paraffin wax, polyethylene wax, sunflower wax, and additionally hydrogenated, isomerized, esterified or hydroxylated forms thereof, alone or in combination.

The hydrogenated vegetable oil refers to a solid or creamy lipid obtained by chemically reacting molecular hydrogen with oil existing as a liquid at room temperature and atmospheric pressure. It is a physiologically acceptable, specifically, cosmetic or pharmaceutically acceptable hydrogenated vegetable oil, and in particular, mineral, animal, vegetable or synthetic oils may be used.

Hydrogenated vegetable oil refers to a product produced as solid or creamy fat by adding hydrogen to unsaturated fatty acid-rich fish oil or edible oil to convert it into saturated fatty acid. was used for the purpose of In the field of cosmetics, hydrogenated vegetable oil has been used for the purpose of increasing moisturizing power, oxidative stability, and product hardness.

However, since the viscosity of the product cannot be effectively increased only by using hydrogenated vegetable oil, the increase in particle size in the product due to the addition of hydrogenated vegetable oil caused problems due to a rough feeling of use, and the oil and hydrogenated oil are separated from each other during long-term storage. has occurred.

The present invention provides a novel oil thickener and manufacturing method for increasing the viscosity of oil, characterized in that it contains only natural ingredients. Provided are cosmetic and external skin preparation compositions using an oil thickener that provides viscosity and formulation stability similar to those of petroleum jelly, but has low cell toxicity and excellent skin affinity and water blocking properties.

According to a preferred embodiment of the present invention, the oil phase (Oil Phase) including refined and unrefined vegetable oil and vegetable hydrogenated oil in the present invention may preferably include 40 to 90% by weight.

In the invention, the content of the oil phase is very important. Because, when used at less than 40% by weight, the oil phase is not uniformly mixed, so a gel-type formulation is not formed well, and when used at more than 90% by weight, the properties of the prepared composition become soggy that filling the container is not smooth, This is because oil is eluted during compression molding, resulting in poor formulation stability.

According to a preferred embodiment of the present invention, the refined and unrefined vegetable oils are physiologically acceptable, specifically, cosmetically acceptable oils, and in particular, in plants or animals, by conventional methods such as pressing, grinding, heating, etc. It is an extracted natural oil. More specifically, volatile or rice bran oil, sunflower seed oil, olive oil, castor oil, palm oil, etc. may be included independently or in combination.

According to a preferred embodiment of the present invention, the natural wax may be included in an amount of preferably 2 to 49% by weight, and most preferably 2 to 30% by weight based on the total weight of the composition.

The reason why the content of the most preferred natural wax in the present specification is 2 to 30% by weight is that when the amount of natural wax is less than 2% by weight, the cosmetic composition lacks elasticity, and when the amount of 30% by weight or more is blended, the natural wax has high hardness. This is because the hardness between the composition is increased due to the high elasticity and the content is less taken during makeup, and the result is difficult to use due to excessive hardness.

According to a preferred embodiment of the present invention, the polyol (polyol) may include preferably 1-20% by weight, most preferably 1-10% by weight based on the total weight of the composition.

The reason why the content of the cellulose aqueous solution is most preferred in the present specification is 1-10% by weight is that when the cellulose aqueous solution is used at 1% by weight or less, it is not formed into an elastic semi-solid form, which is a mixture of vegetable liquid oil and vegetable hydrogenated oil, and is a general oil-based type When the polyol aqueous solution was mixed in excess of 10% by weight, the mixing ratio of the contents was uneven and the smoothness and elasticity were insufficient in the feeling of use, resulting in poor quality. to be.
