Description

Fine dust dustproof composition {COMPOSITION FOR ANTI-FINE DUST}

The present description relates to a fine dust-proof composition.

When dust accumulates in the body, human immunity decreases and can cause various diseases such as heart disease or respiratory disease. It can even cause bronchostitial stricture, and prolonged inhalation increases the prevalence of asthma or lung disease, and early mortality.

The skin acts as a barrier between the organism and the environment, the outermost part of our body in direct contact with the dust, and when exposed to pollution often directly, this barrier function is reduced. In particular, fine dust is 20 times smaller than pores, so it can easily penetrate the skin. In fact, air pollutants such as fine dust are known to have serious effects on skin health. In the short term, premature aging, lack of moisture, increased fine lines and wrinkles, and in the long term irreversible skin damage can lead to serious diseases such as skin cancer, as the skin loses its ability to protect the body from environmental factors. .

Therefore, there is a need for research on cosmetics to isolate dust, which is a harmful substance that is harmful to the skin and sometimes causes fatal disorders to the human body.

In particular, in recent years, as fine dust adheres to the hair due to frequent going out, and the fine dust is frequently introduced into the skin or the human body, efforts to reduce the adhesion of fine dust to the hair continue.

The anti-vibration composition according to the embodiment is to provide a hair cosmetic having excellent anti-vibration function to prevent the fine dust from sticking to the hair in order to block the possibility of the fine dust adhering to the hair and then moving into the skin or the human body.

According to an embodiment, a nonvolatile silicone oil having a weight average molecular weight of 800,000 g/mol to 1,100,000 g/mol, an oil having a triglyceride structure, and hydrogenated polyisobutene are included as active ingredients, and the nonvolatile silicone oil Provides a dust-proof composition containing 2% by weight or more with respect to the total amount of the dust-proof composition.

The nonvolatile silicone oil may have a viscosity of 77,000 cs to 140,000 cs.

The nonvolatile silicone oil may have a structure represented by Formula 1 below.

[Formula 1]

The nonvolatile silicone oil may be included in an amount of 2% to 5% by weight based on the total amount of the dustproof composition.

The nonvolatile silicone oil may be included in an amount of 3% to 5% by weight based on the total amount of the dustproof composition.

The oil having the triglyceride structure may be included in an amount of 0.1% to 10% by weight based on the total amount of the dustproof composition.

The oil having the triglyceride structure may include Caprylic/Capric Triglyceride, Coconut Oil, Sunflower Seed Oil, or a combination thereof.

The hydrogenated polyisobutene may be included in an amount of 0.1% to 10% by weight based on the total amount of the dustproof composition.

The anti-vibration composition may be a hair cosmetic composition.

The hair cosmetic composition may be a shampoo, treatment or essence.

According to one embodiment, the anti-vibration composition of the present invention can minimize a phenomenon in which dust, particularly fine dust, sticks to the hair. Specifically, by limiting the chemical structure, molecular weight, and viscosity of the nonvolatile silicone oil contained as an active ingredient in the anti-vibration composition, it is possible to significantly reduce the adsorption power of fine dust to the hair.

Hereinafter, embodiments of the present invention will be described in detail so that those of ordinary skill in the art can easily implement the present invention. However, the present invention may be implemented in various different forms, and is not limited to the embodiments described herein.

In the present specification, the term'dustproof' means that dust is attached to the skin or hair, or that dust temporarily attached to the hair is removed from the hair to prevent or minimize penetration into the skin or the human body. That is, when the dustproof composition of the present specification is applied to the hair, it is possible to minimize the adhesion of dust to the hair, and even if the dust is attached to the hair, it can be easily removed by physical force such as wind, and further applied to the skin. Even if dust flows into the cosmetic composition, the dust floats in the cosmetic composition, and penetration into the skin can be prevented.

In the present specification, dust refers to particulate matter mixed in the atmosphere, and usually means a suspended substance having a particle diameter of 0.1 μm to 10 μm. In particular, when the particle diameter is 10 μm or less, it is referred to as fine dust, and when the particle diameter is 0.1 μm or less, it is also referred to as ultrafine dust. Here, the particle diameter may mean the average value of each particle diameter of the fine dust. Dust is a material including a material derived from nature such as sand, soil and pollen, or a material derived from industrial processes such as carbon, carbon combustion products, metal salts and heavy metals. The form of dust present can be fume, mist, smoke, vapor or mist.

In the present specification, when a portion such as a layer, a film, a region, or a plate is said to be “on” another portion, this includes not only the case where the other portion is “directly above” but also the case where there is another portion in between. Conversely, when one part is "directly above" another part, it means that there is no other part in the middle.

Hereinafter, a dustproof composition according to an embodiment is described.

The anti-vibration composition according to an embodiment comprises a nonvolatile silicone oil having a weight average molecular weight of 800,000 g/mol to 1,100,000 g/mol, an oil having a triglyceride structure, and hydrogenated polyisobutene as active ingredients, and the nonvolatile The silicone oil is included in an amount of 2% by weight or more based on the total amount of the dustproof composition.

When the anti-vibration composition according to the embodiment includes the oil having the triglyceride structure and the hydrogenated polyisobutene, and a nonvolatile silicone oil having a weight average molecular weight of 800,000 g/mol to 1,100,000 g/mol, Since the coating power of the anti-vibration composition is strengthened, the adsorption power of fine dust on the hair can be greatly reduced.

When the weight average molecular weight of the non-volatile silicone oil is less than 800,000 g/mol, the coating power of the anti-vibration composition on the hair decreases, resulting in stickiness, which increases the adsorption power of fine dust on the hair. In addition, the negative effect of decreasing the brightness also appears.

When the weight average molecular weight of the non-volatile silicone oil exceeds 1,100,000 g/mol, it becomes an ultra-high molecular material, making it difficult to prepare, making it impossible to prepare a shampoo, treatment, or essence, making it unsuitable for a hair cosmetic composition.

In addition, even when the non-volatile silicone oil is included in an amount of less than 2% by weight based on the total amount of the vibration-proof composition, the coating effect of the dust-proof composition on the hair is insignificant, and the adsorption power of fine dust on the hair increases.

The non-volatile silicone oil may have a viscosity of 77,000 cs (centi stock) to 140,000 cs with a weight average molecular weight of 800,000 g/mol to 1,100,000 g/mol.

When the non-volatile silicone oil has a weight average molecular weight in the range and a very high viscosity in the range, the coating power of the anti-vibration composition on the hair is further strengthened, and the adsorption capacity of fine dust on the hair can be further reduced. .

Even if the non-volatile silicone oil has a weight average molecular weight in the above range, if it has a viscosity of less than 77,000 cs, there is a problem that the coating power of the anti-vibration composition on the hair is slightly lowered, and if it has a viscosity of more than 140,000 cs, the crude liquid It is difficult to make it not suitable as a hair cosmetic composition.

Specifically, the nonvolatile silicone oil may have a structure represented by Formula 1 below.

[Formula 1]

When the weight average molecular weight and viscosity of the compound having the structure of Formula 1 are limited as described above, the coating power of the anti-vibration composition on the hair is very excellent.

Specifically, the nonvolatile silicone oil having a weight average molecular weight of 800,000 g/mol to 1,100,000 g/mol may be included in 2% to 5% by weight, more specifically 3% to 5% by weight based on the total amount of the composition. . When the nonvolatile silicone oil having a weight average molecular weight of 800,000 g/mol to 1,100,000 g/mol is included in an amount of more than 5% by weight based on the total amount of the dustproof composition, the lightness and fine dust protection effect almost reach a saturation level, and the ratio It is uneconomical to include more than 5% by weight of the volatile silicone oil based on the total amount of the anti-vibration composition.

The oil having the triglyceride structure may be included in an amount of 0.1% to 10% by weight based on the total amount of the hair cosmetic composition. When the oil having the triglyceride structure is included in the amount, there is an effect of improving the spreadability of the composition.

The oils having the triglyceride structure are CAPRYLIC/CAPRIC TRIGLYCERIDE, COCOS NUCIFERA (COCONUT) OIL, MACADAMIA TERNIFOLIA SEED OIL, HELIANTHUS ANNUUS (SUNFLOWER) SEED OIL, VITIS VINIFERA (GRAPE) SEED OIL, BORAGOED OILBA (GRAPE) SEED OIL, BORAGO OFFICINALIS ) SEED OIL or a combination thereof may be included.

Specifically, the oil having a triglyceride structure may include Caprylic/Capric Triglyceride, Coconut Oil, Sunflower Seed Oil, or a combination thereof.

More specifically, the oil having the triglyceride structure may be Caprylic/Capric Triglyceride or Coconut Oil.

Compared to the nonvolatile silicone oil having a weight average molecular weight of 800,000 g/mol to 1,100,000 g/mol, the oil having a triglyceride structure has a small molecular weight and a bulky structure, and thus a structure other than a triglyceride structure Eggplant may have better spreadability of the composition than when using oil.

The hydrogenated polyisobutene may be included in an amount of 0.1% to 10% by weight based on the total amount of the hair cosmetic composition. Since the hydrogenated polyisobutene has a linear chain, when applied to the hair, the hair surface can be effectively coated. As the hydrogenated polyisobutene is included in the above range, the coating effect on the hair is further improved. I can make it.

When the anti-vibration composition according to an embodiment includes non-hydrogenated polyisobutene instead of the hydrogenated polyisobutene, the non-hydrogenated polyisobutene has a chain of a bulky structure rather than a linear, coating effect on hair There is a problem that is lowered.

The anti-vibration composition according to the exemplary embodiment may be one for dust-proofing fine dust having a particle diameter of 10 μm or less. The particle size size is not limited and may be 100 μm or less, 90 μm or less, 70 μm or less, 50 μm or less, 30 μm or less, 20 μm or less, 15 μm or less, or 10 μm or less.

In the above aspect, the anti-vibration composition may be a hair cosmetic composition, and the hair cosmetic composition may be a shampoo, treatment, or essence.
