Description

COMPOSITION FOR ANTI-FINE DUST [0002]

The present disclosure relates to a fine dust-proofing composition.

If the dust accumulates in the body, the body's immune system will drop, and it can cause various diseases such as heart disease and respiratory disease. Even causing bronchial stenosis and prolonged inhalation increase the prevalence of asthma and lung disease and increase early mortality.

The skin acts as a barrier between the organism and the environment at the outermost of our body, which is in direct contact with the dust. This barrier function is often impaired when exposed directly to pollution. In particular, fine dust is 20 times smaller than pores and can easily penetrate the skin. In fact, air pollutants such as fine dusts are known to have a profound effect on skin health. In the short term, it can lead to premature aging, lack of moisture, wrinkles and wrinkles, and serious illnesses such as skin cancer, with skin irreparable in the long run losing its ability to protect the body from environmental factors .

Therefore, there is a need for research into cosmetics to isolate dust, which is harmful to the skin and sometimes harmful to human body, from the skin.

Particularly, in recent years, fine dust adheres to the hair due to frequent outings, and the fine dust is often introduced into the skin or the human body. Therefore, efforts are being made to reduce the fine dust adhesion to the hair.

The anti-vibration composition according to one embodiment is intended to provide a hair cosmetic excellent in dustproof function, which prevents fine dust from sticking to hair in order to prevent the possibility that the fine dust adheres to the hair and then moves into the skin or the human body.

According to one embodiment, there is provided a dustproof composition comprising a nonvolatile silicone oil having a weight average molecular weight of 800,000 g / mol to 1,100,000 g / mol and a silicone acryl polymer as an active ingredient and having a viscosity of 300 cs to 800 cs.

The anti-vibration composition according to one embodiment will be described below.

The anti-vibration composition according to one embodiment contains a nonvolatile silicone oil having a weight average molecular weight of 800,000 g / mol to 1,100,000 g / mol and a silicone acrylic polymer as an active ingredient, and has a viscosity of 300 cs to 800 cs.

When the anti-vibration composition according to one embodiment includes a nonvolatile silicone oil having a weight average molecular weight of 800,000 g / mol to 1,100,000 g / mol together with the silicone acryl-based polymer, the coating strength of the anti- So that the fine dust attracting force against the hair can be significantly lowered.

When the weight average molecular weight of the nonvolatile silicone oil is less than 800,000 g / mol, the coating power of the anti-vibration composition against hair is lowered to cause tackiness, thereby increasing the fine dust attraction force against hair. Also, a negative effect of decreasing brightness is also exhibited.

When the weight average molecular weight of the nonvolatile silicone oil exceeds 1,100,000 g / mol, it becomes an ultra-high molecular weight material and difficult to prepare the crude liquid. Therefore, it is impossible to prepare shampoo, treatment or essence and it is not suitable as a hair cosmetic composition.

Further, by limiting the weight average molecular weight of the nonvolatile silicone oil to 800,000 g / mol to 1,100,000 g / mol and limiting the viscosity of the final dustproof composition to 300 cs (centi stock) to 800 cs, The coating power can be further improved and the fine dust attraction force against the hair can be further reduced.

When the viscosity of the anti-vibration material is less than 300 cs, the coating ability of the anti-vibration material against hair is lowered. When the viscosity of the anti-vibration material is more than 800 cc, the composition is not suitable as a hair cosmetic composition.

Specifically, the nonvolatile silicone oil may have a structure represented by the following formula (1).

[Chemical Formula 1]

When the weight average molecular weight of the compound having the structure of Formula 1 (nonvolatile silicone oil) is limited as described above, the coatability of the anti-vibration composition against hair becomes 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 an amount of 1 wt% to 20 wt%, more specifically 5 wt% to 15 wt% 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 contained in an amount of less than 1% by weight based on the total amount of the dustproof composition, it is difficult to function as a dust- / mol to 1,100,000 g / mol is contained in an amount of more than 20% by weight based on the total amount of the anti-vibration composition, the feeling of damp and sticky feeling is displayed, and the effect of fine dust prevention is almost reached to the saturation level Which is uneconomical.

The silicone acryl-based polymer forms a protective film on the hair to block the adsorption of hair on harmful substances and fine dust in the air, and is included for the purpose of ensuring a light and pleasant feeling when applied to hair.

For example, the silicone acryl-based polymer may be selected from the group consisting of an acrylate / dimethicone copolymer, an acrylate / dimethicone methacrylate copolymer, and an acrylate / polytrimethylsiloxy methacrylate copolymer (Acrylate / polytrimethylsiloxymethacrylate copolymer). When the silicone acrylic polymer is included, a protective film is formed on the surface of the hair to prevent fine dust or the like in the air from being adsorbed on the hair. For example, the silicone acryl-based polymer may comprise an acrylate / polytrimethylsiloxy methacrylate copolymer.

The acrylate / polytrimethylsiloxy methacrylate copolymer may include a repeating unit represented by the following formula (2).

(2)

In Formula 2,

R ¹ is hydrogen or a substituted or unsubstituted C1 to C10 alkyl group,

R ² is represented by the following formula (3)

(3)

In Formula 3,

L ¹ and L ² are each independently a substituted or unsubstituted C1 to C10 alkylene group.

As shown in Formula 2, the acrylate / polytrimethylsiloxy methacrylate copolymer has a structure in which a plurality of trimethylsiloxy groups have a dendrimer structure with acrylate as a backbone, While forming a protective film on the hair to prevent fine dust and harmful substances in the air from depositing on the hair.

For example, the silicone acrylic polymer may be included in an amount of 0.1 to 20% by weight, for example, 0.1 to 15% by weight, for example, 0.1 to 10% by weight based on the total amount of the vibration damping composition. When the content is within the above range, the feeling of use and the stability of formulation are excellent, and the effect of forming a hair protective film can be excellent.

The nonvolatile silicone oil and the silicone acrylic polymer may be contained in a weight ratio of 10: 1 to 10: 3.

The anti-vibration composition may further comprise a silicone-free oil.

The silicone-free oil may have 12 to 16 carbon atoms and may have a weight average molecular weight of 170 g / mol to 350 g / mol. If the carbon number and the weight average molecular weight of the silicone-free oil are out of the above range, the final anti-dust composition can not be uniformly dispersed (the components do not easily aggregate) and the coating film formation on the hair may not be uniform.

For example, the silicone-free oil may include Coconut Alkane, Dicaprylyl Ether, C12-15 Alkyl Benzoate substituted with 12 to 15 carbon atoms, or combinations thereof .

The dust-proofing composition according to one embodiment may be to dust the fine dust having a particle diameter of 10 mu m or less.
