  • Publication number: 20180243192
    Abstract: The present specification relates to a moldable solid preparation hair care composition containing a cationic surfactant, an anionic surfactant and a thickener, wherein the amount of cationic surfactant is 0.1-5 wt % on the basis of the total composition, the amount of anionic surfactant is greater than or equal to 0.1 wt % and less than 1 wt % on the basis of the total composition, and the amount of thickener is 0.1-15 wt % on the basis of the total composition. According to one aspect of the present invention, the hair care composition has excellent moldability as a solid preparation and, simultaneously, exhibits remarkable conditioning effects.

  • Publication number: 20160309184
    Abstract: Disclosed are methods, apparatuses, and systems for encoding and decoding an image. The present invention provides an intra prediction unit that receives an input image, calculates a correlation between a Luma area block and Chroma area block in the input image in intra prediction, removes high frequency ingredients by low-pass filtering an encoded luma pixel based on the calculated correlation, and generates a prediction block by applying an LM chroma mode, which is an extended chroma mode technique, to the luma pixel removed therefrom the high frequency ingredients.

  • Publication number: 20160241861
    Abstract: Disclosed are methods, apparatuses, and systems for encoding and decoding an image. The present invention provides an intra prediction unit that receives an input image, removes high frequency ingredients by low pass filtering an encoded luma pixel value in the input image during intra prediction, and generates a prediction block by predicting a chroma pixel value by using a low pass filter (LPF) LM chroma mode for applying an LM chroma mode, which is an extended chroma mode technique for generating a prediction block by predicting the chroma pixel value by applying a correlation between color planes to the luma pixel value having removed therefrom the high frequency ingredients.

  • Patent number: 9358190
    Abstract: The present invention relates to a dyeing composition. More particularly, the present invention provides a dyeing composition comprising an ether-based nonionic surfactant, an ether-based oil and alcohol. Preferably, the ether-based nonionic surfactant, the ether-based oil and the alcohol have the same number of carbon atoms. The dyeing composition according to the present invention comprises the ether-based nonionic surfactant, the ether-based oil and the alcohol, forms a multi-lamellar liquid crystal structure, allows for ease of material application and maintains excellent color formation, and particularly, mitigates pungent smell, eye irritation and the like.

  • Patent number: 9028563
    Abstract: The present invention relates to a hair dye composition, and more particularly, to a foam-type hair dye composition comprising: a first agent including a dye and an alkaline agent and a second agent including an oxidant; and a nonionic viscosity increasing agent of a PEG-aliphatic acid ester or a PPG-aliphatic acid ester in one or both of the first agent and the second agent, thereby largely improving dyeing properties without dripping after the composition is coated on hair.

  • Patent number: 8808150
    Abstract: An exercise bicycle wherein when rotating the wheels by rotating pedals, the user feels the bicycle moving forward and being tilted left and right as when riding a bicycle outdoors, and also feels as if the user is riding on a slope, a plain road, etc., thus preventing the user from feeling monotonous and tedious and allowing the user to feel as if the user is riding a bicycle outdoors, thereby increasing the amount of exercise.
