Kosmetika Bahan Alam-Body Lotion (Rumput Laut)

Summary

In this educational video, Oki Haradi, a pharmacy student from Universitas Nahdlatul Ulama NTB, presents an analysis of a journal on the use of seaweed (*Gracilaria ferulosa* and *Turbinaria conoides*) in body lotion formulation. Highlighting the benefits of natural ingredients, the video explains how seaweed’s bioactive compounds, like antioxidants, can improve skin care products. The process of preparing seaweed, formulating the lotion, and testing its properties like viscosity, antioxidant activity, and stability is thoroughly covered. The results suggest that seaweed-based lotions are effective, safer, and have fewer side effects compared to synthetic alternatives, providing an eco-friendly cosmetic option.

• 😀 The main topic of the video is a body lotion made from seaweed, with a focus on the natural ingredients and the scientific process behind it.
• 😀 Seaweed, specifically Gracilaria ferukosa and Turbinaria konoides, is used as the key ingredient for the body lotion, known for its bioactive compounds like antioxidants.
• 😀 The video highlights the benefits of using natural ingredients over synthetic chemicals in cosmetic products, emphasizing minimal side effects and safety.
• 😀 The preparation process involves cleaning the seaweed, soaking it, and blending it to create a paste used in the lotion.
• 😀 The lotion formulation consists of an oil phase and an aqueous phase, which are combined at specific temperatures to create a smooth and effective lotion.
• 😀 Various scientific tests, including viscosity, pH, and antioxidant activity, were conducted on the lotion to assess its quality and effectiveness.
• 😀 The antioxidant activity of the seaweed-based lotion was measured using the DPPH method, showing good free radical neutralization.
• 😀 The lotion's pH was tested and found to be neutral (7.23), making it safe for skin use, and it showed good spreadability and moisture content.
• 😀 In conclusion, the seaweed-based lotion outperformed both commercial products and synthetic alternatives in terms of effectiveness and safety, making it a preferable choice for long-term skin health.

Q & A

What is the main purpose of the video presented by Oki?

The main purpose of the video is to share educational content on health and tourism, particularly focusing on the analysis of a journal related to the use of natural cosmetic ingredients, such as seaweed, in body lotion formulations.

Who is the target audience of this video?

The target audience is viewers interested in health and tourism, especially those seeking information on natural ingredients in cosmetics, and students or professionals in the pharmaceutical and health fields.

What is the title of the journal discussed in the video?

The journal discussed in the video is titled 'Characterization of Seaweed Species Gracilaria Ferukosa and Turbinaria Konoides as Raw Materials for Body Lotion.'

What are the main ingredients in the body lotion discussed in the video?

The main ingredients in the body lotion are two species of seaweed: Gracilaria Ferukosa and Turbinaria Konoides, which are used to create an emulsion for moisturizing.

What are the potential benefits of using seaweed in cosmetics, according to the video?

Seaweed contains bioactive compounds, such as phenolic acids, flavonoids, and alkaloids, which act as antioxidants, helping to protect the skin from environmental stress and reduce the effects of free radicals.

How is the seaweed prepared for use in the body lotion?

The seaweed is first cleaned with demineralized water to remove impurities, then soaked for 12 hours. After soaking, it is homogenized with water to form a seaweed paste, which is then mixed into the lotion.

What are the phases involved in the body lotion formulation?

The body lotion formulation involves two phases: the oil phase (containing ingredients like stearic acid and liquid paraffin) and the water phase (which includes the seaweed paste, glycerin, and demineralized water). These phases are mixed at a temperature of 70–75°C to form a homogeneous lotion.

What is the significance of the 'IC 50' value mentioned in the journal?

The 'IC 50' value refers to the concentration of a substance that is required to inhibit 50% of the antioxidant activity. A lower IC 50 value indicates higher antioxidant activity, suggesting the effectiveness of the seaweed in neutralizing free radicals.

What tests were conducted to evaluate the body lotion's properties?

Several tests were conducted, including viscosity measurement, water content determination, antioxidant activity (using the DPPH method), pH testing, spreadability, and stability tests. These tests evaluate the lotion's performance and its ability to provide moisture and antioxidant protection.

What were the findings related to the body lotion's stability and effectiveness?

The study found that the best combination of seaweed paste resulted in a body lotion with good stability, moderate antioxidant activity, and an acceptable pH level. The lotion with seaweed performed better compared to both a formulation without seaweed and a commercial product.
