化妝品原料學 翻譯 英文翻譯中文

請問有人可以幫我翻譯嗎?看不太懂

部要翻譯機的~我查過了~看還是不太懂

謝謝!!!

•Disadvantage: 1.The charge at the interfacial region at the shipping plane of the particle (Zeta potential) plays a significant role in stabilizing the emulsion. 2.High zeta potential makes the particle repel from each other preventing coalescence or aggregation. 3.zeta potential can be brought in an optimum range by using appropriate salt, buffer, and other ionic species.

~~~~~~~~~~~~~~~~~~~

Zeta potential(ζ-potential)

•Zeta potential is an abbreviation for electrokinetic potential in colloidal systems •The significance of zeta potential is that its value can be related to the stability of colloidal dispersions.•The zeta potential indicates the degree of repulsion between adjacent, similarly charged particles (the vitamins) in a dispersion.

~~~~~~~~~~~~~~~~~~~

•Hydrogel is a network of polymer chains that are water-insoluble, sometimes found as a colloidal gel in which water is the dispersion medium. Hydrogels are superabsorbent (they can contain over 99% water) natural or synthetic polymers. Hydrogels possess also a degree of flexibility very similar to natural tissue, due to their significant water content.

~~~~~~~~~~~~~~~~~~~

Common uses for hydrogels

•currently used as scaffolds in tissue engineering. When used as scaffolds, hydrogels may contain human cells in order to repair tissue. •environmentally sensitive hydrogels. These hydrogels have the ability to sense changes of pH, temperature, or the concentration of metabolite and release their load as result of such a change.

~~~~~~~~~~~~~~~~~~~

•as sustained-release delivery systems •medical electrodes using hydrogels composed of cross linked polymers (polyethylene oxide, polyAMPS and polyvinylpyrrolidone)

Update:

Disadvantage:

A. Time consuming

B. Requires a significant amount of surfactant/co-surfactants(~25%) and therefore, warrant concerns about skin irritancy.

Update 2:

Surfactant-Free Nano-Dispersion

•These dispersions are nano-emulsions that can hold a large quantity (up to 50%) of oil in water with relatively a small quantity of lipid-based emulsifying agent.

Update 3:

•Advantage:

1. low skin-irritation

2. size < 500 nm

3. stability in low temperature to 40oC~50oC over 1or more years

4.types: gels, creams, lotions, serums, and spray formulations.

Update 4:

Skin is the largest organ of the body with a surface area of about 2 m2 for an average adult human.

It varies in thickness from a few hundred microns to 4 mm depending on the part of the body it covers.

Update 5:

The functions of the skin:

1. protecting the body organs

2. providing cutaneous sensation

3. acting as an excretory

The skin is constantly exposed to the atmospheric and bombarded by harsh elements:

1. bright sun light that UV-A(330-400nm) and

UV- B(280-330nm) radiations

Update 6:

2. atmospheric pollutant and extreme wet or dry condition

The easiest method to delivery an active ingredient to the skin is by dissolving it in a suitable solvent and applying the solution to the skin

Update 7:

The disadvantage of this system is obvious : not all actives are soluble in water.

Advantages of a suitable “delivery system” include the possibility of reduced toxicity, controlled release and deep penetration of an active into the skin.

    •Disadvantage:1.收費 (Zeta 潛在) 粒子的船舶飛機在介面區域穩定乳液的重大作用。

    2.高 zeta 潛在使得防止聚結或聚合互相排斥的粒子。

    3.澤塔鐘斯潛在能通過使用適當的鹽、 緩衝區和其它離子物種帶來的一個優化的範圍。

    ~~~~~~~~~~~~~~~~~~~澤塔鐘斯 potential(ζ-potential)

    •Zeta 潛力在膠體系統是電動潛力的縮寫•The zeta 潛在意義在於它的值可能與相關的膠體穩定性。•The zeta 潛在指示斥分散在鄰近的同樣帶電粒子 (維生素) 之間的程度。

    ~~~~~~~~~~~~~~~~~~~

    •Hydrogel 是一個網路是水不溶性,有時發現作為膠體凝膠中的水是分散介質的高分子鏈。水凝膠是高吸水樹脂 (它們可以包含超過 99%水) 天然或人工合成的聚合物。水凝膠還具備一定程度的靈活性非常類似于自然的組織,由於以其顯著的含水量。

    ~~~~~~~~~~~~~~~~~~~水凝膠的常見用途

    •currently 作為組織工程支架材料使用。作為支架使用時,水凝膠可能包含以修復組織的細胞。•environmentally 敏感水凝膠。這些水凝膠能夠感覺到的 ph 值、 溫度、 或代謝物濃度變化並釋放其負載,這種變化的結果。
