Description

(Petrolatum jelly (Vaseline) replacing agent having a highly improved physical property composed of a natural component and a method for producing the same,

The present invention provides a novel oil thickener and a method for producing the same which increase the viscosity of an oil, comprising only natural ingredients.

The oil thickening agent may be used as a skin protecting external preparation or cosmetic in itself, and is often used as a method for imparting formulation stability and maintaining an effective active substance on the skin surface for a long time in cosmetics or medicines.

As a representative oil thickener, Vaseline can be obtained by purifying the oily phase material obtained by solvent degassing of the vacuum distillation residue of crude oil. The main component is hydrocarbon of C24-C43 and amorphous substance. White petroleum jelly which can be used in cosmetics and pharmaceuticals is commercially available because it has a high degree of purification.

Vaseline is frequently used in skin care cosmetics, makeup cosmetics, and dermatologic drugs to achieve formulation stability and a desired viscosity and hardness.

However, although Vaseline has an excellent gradual effect, it can generally have a low hardness, which can result in an overly sticky formulation, which is hindering the formulation of formulations with low stickiness and proper hardness.

Vaseline is a substance obtained from the vacuum distillation residue of crude oil and is known to have environmental pollution and toxicity which is unsuitable for application to sensitive skin or wounds.

Accordingly, there is a demand for an oil thickener which is low in skin toxicity and irritation, is eco-friendly, and can impart a viscosity-increasing effect similar to petrolatum and a harder hardness.

The oil means a lipid present in a liquid at room temperature and at atmospheric pressure. Generally, an oil of an 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. Thus, it has not been possible to make formulations with viscosity and hardness suitable for skin application with oil alone.

Therefore, although a method of obtaining a suitable hardness by heating after containing wax is generally used, it is possible to obtain a hardness comparable to that of petroleum jelly, as compared with petroleum jelly, which has a low viscosity and a hard form, It was impossible. In addition, since wax has high crystallinity, there is a problem that the liquid oil becomes unstable and the hardness becomes unstable after a lapse of time.

The oil is physiologically acceptable, specifically a cosmetically acceptable oil, and is a naturally derived oil extracted by a conventional method such as compression, grinding and heating in plants or animals. More specifically, castor oil, sunflower seed oil, avocado oil, olive oil, palm oil, and the like having volatile or nonvolatile characteristics may be included independently or in combination.

The wax means a lipid present as a solid at room temperature and at atmospheric pressure. It is physiologically acceptable, specifically a cosmetically or pharmaceutically acceptable wax, in particular a mineral, animal, plant or synthetic origin. More specifically, hydrocarbon waxes, silicone waxes, fluoro waxes and their hydrogenated, isomerized, esterified or hydroxified forms may be included independently or in combination. Examples of the wax include lanolin wax, lemon wax, microcrystalline wax, montan wax, beeswax, berry wax, cell wax, alpha wax, orange wax, ocherite wax, ozokerite wax, , Chinese insect waxes, carnauba waxes, candelilla waxes, paraffin waxes, polyethylene waxes, sunflower waxes and additionally their hydrogenated, isomerized, esterified or hydroxified forms may be included independently or in combination.

The vegetable hydrogenated oil means a solid or creamy lipid obtained by a chemical reaction of molecular hydrogen with an oil present as a liquid at room temperature and at atmospheric pressure. It is a physiologically acceptable and specifically vegetable hardening oil acceptable for cosmetic or pharmaceutical use, in particular minerals, animal, vegetable or synthetic origin oils.

Vegetable cured oil refers to a product produced by adding hydrogen or edible oil to a fatty acid or fatty acid and converting it into a saturated fatty acid and producing it as a solid or cream-type oil. It mainly improves the oxidation stability of oil in the field of food, gives plasticity and hardness . In the field of cosmetics, vegetable oils have been used for the purpose of increasing moisture and oxidative stability and hardness of products.

However, since the viscosity of the product can not be efficiently increased only by the use of the vegetable hardened oil, the increase of the particle size in the product due to the addition of the vegetable hardened oil has caused problems due to rough feeling, .

The present invention provides a novel oil thickener and a method for producing the same which increase the viscosity of an oil, comprising only natural ingredients. Provided is a cosmetic and dermatological composition composition using an oil thickening agent which is low in cytotoxicity and excellent in skin affinity and water occlusion property while providing viscosity and formulation stability similar to petrolatum.

According to a preferred embodiment of the present invention, in the present invention, an oil phase containing vegetable liquid oil and vegetable curing oil may preferably be contained in an amount of 50 to 80% by weight.

The content of the oil phase in the invention is very important. If it is used in an amount of less than 50% by weight, the oil phase may not be uniformly mixed to form a gel-type formulation. If the oil phase is used in excess of 80% by weight, the properties of the prepared composition may become poor, This is because the oil is eluted during compression molding and the stability of the formulation is poor.

According to a preferred embodiment of the present invention, the vegetable liquid oil is a physiologically acceptable oil, specifically a cosmetically acceptable oil. In particular, the vegetable liquid oil is a natural oil extracted by a conventional method such as compression, It is derived oil.
