The present invention provides an oil-in-water emulsion composition containing (A) an aqueous phase containing a diol, (B) an oil phase, (C) a polyoxyalkylene-modified silicone, and (D) a tackifier, the diol content being 1-20 mass% relative to the entire composition, the oil phase content being 1-50 mass% relative to the entire composition, and the tackifier content being 1-50 mass% relative to the entire composition. The content of the polyoxyalkylene-modified silicone (C) is 0.2-2.5 mass%, the tackifier (D) is at least one selected from the group consisting of sodium polyacrylate-grafted starch and acrylic acid (ester)-based crosslinked polymer-2 sodium, and the content of the tackifier (D) is 0.5-5 mass% relative to the whole composition. The oil-in-water type emulsion composition has matte appearance similar to mashed potatoes and can endow skin with natural matte sensation after being coated on the skin, and a user can feel quick absorption sensation and obvious phase inversion sensation without feeling sticky after using the oil-in-water type emulsion composition.

The invention discloses a dendrobium officinale protocorm-like body efficient proliferation culture medium and an application method thereof.The culture medium takes 1 / 2 MS as a basic culture medium, 30 g / L of mashed potatoes, 30 g / L of sucrose, 7 g / L of agar, 1 g / L of activated carbon, 0.2 mg / L of naphthylacetic acid (NAA) and 2 mg / L of 6-benzylamino adenine (6-BA) are added, pH is adjusted to 5.5-6.0, and preparation of the dendrobium officinale protocorm-like body efficient proliferation culture medium is completed through mother liquor preparation, ingredient mixing, pH adjustment and 121 DEG C high-pressure steam sterilization for 30 min. During application, the protocorm-like body needs to be inoculated into the culture medium through high-pressure steam sterilization, ultra-clean bench preparation, standardized split charging and sterile inoculation operation, and then is cultured under the conditions of (27 + / -2) DEG C, 12h / d illumination and 4000-5000lx. According to the method, the proliferation coefficient of the protocorm-like body cultured for 30 days is not lower than 5.0, the survival rate is not lower than 95%, browning is avoided, large-scale proliferation of the dendrobium officinale protocorm-like body can be efficiently achieved, and technical support is provided for follow-up research and production.
