Abstract ▼ AI-Helper

In this study, We investigated the properites of nano-emulsions containing hydrogenated lecithin prepared by high pressure homogenizer. The size of droplet of emulsions prepared by homogenizer at various rpm (rotation per minute) was not measured due to the unstability of emulsions, however, the size of droplet of nano-emulsions prepared by high pressure homogenizer was around 300 nm and the appearance of emulsions was bluish. The stability of emulsions with various lecithin concentration was tested against time. POV (Peroxide value) of emulsions were plotted against time. POVs of emulsions prepared with an egg lecithin and a soy lecithin were increased with time, however, POV of emulsion with Lecinol S-$10^{(R)}$ was kept constant within 60 hours and at $60^{\circ}C$. In consumer test, the nano-emulsion showed higher affinity regardless of skin type. Both of irritation scores of emulsions were similar.

문제 정의

Skin sensory characteristics of a emulsion are the result of the ingredients in the marketed products as well as the physical form in which they have been formulated. The objective of this study was to identify the sensory characteristics of two types of emulsions. Panel consisted of 38 women who had been selected for their high degree of sensory acuity.

가설 설정

1. The size of droplet of emulsions prepared by homogenizer varying rpm was not measured due to the unstability of emulsions. The size of droplet of emulsions prepared by high pressure homogenizer was around 300 nm and the appearance of emulsions was bluish.
2. Emulsions with various lecithin were tested against time. POV (Peroxide value) of emulsions were plotted against time.
3. In consumer test, the nanoemulsion showed higher affinity regardless of skin type.
4. Both of irritation scores of emulsions were similar.

제안 방법

2 g on a 25 mm Plain Hill Top Chamber (Hill Top Companies, Cincinnati, OH, USA) to the skin of the upper outer arm of 30 human volunteers for up to 4 hours. Treatment sites are assessed for the presence of irritation using a four point scale (Table I) at 24, 48 and 72 hours after patch removal. A volunteer with a '+' or greater reaction at any of the assessments is considered to have demonstrated a 'positive' irritant reaction and treatment with the causative substance does not proceed on that person.

대상 데이터

Cosmetic grade of light mineral oil from Kuk-dong (Korea) and silicone oil (Silicone 556®) from Dow Corning (USA) were used.
For the sensory evaluation, panel was consisted of 38 women who had been selected for their high degree of sensory acuity. Panels were given by reflecting the skin types.

이론/모형

Free fatty acid value(AV) and conjugated dienoic acid value (CDNV) were determined according to the AOAC method[11].
The subjects were asked to assess the degree of liking during spreading. The results were marked on an analogue scale.
