BIKIN FORMULASI BODY LOTION SENDIRI !! | Tugas Skripsi

Summary

In this video, the creator walks through the process of making a body lotion as part of their thesis project. The video covers the formulation design, ingredient weighing, and careful preparation of both the oil and water phases. The creator shares insights into the importance of correct ingredient ratios and offers tips on reading journals and handbooks to help with formulation. They also demonstrate making two samples, one with and one without seaweed extract, followed by physical evaluations like pH tests and spreadability. The video concludes with a test of the lotion's effectiveness on the creator's friend's skin.

Takeaways

• 😀 The video is about creating a body lotion as part of a thesis project.
• 😀 The process involves weighing ingredients for both the oil phase and water phase separately before combining them.
• 😀 The formulation of the body lotion is a unique design created by the video creator themselves.
• 😀 The formulation includes an emollient base, emulsifier, surfactant, humectant, lubricant, preservative, and perfume.
• 😀 Precision in weighing the ingredients is critical, as the lotion's final result depends on getting the proportions right.
• 😀 There is a two-phase process in lotion creation: the oil phase and the water phase, which must be mixed at the correct time to form lotion.
• 😀 The creator uses a hot plate to heat the phases, though a water bath can also be used.
• 😀 For consistency and smoother mixing, the water phase takes longer to homogenize compared to the oil phase.
• 😀 The creator made two samples: one with the basic lotion and another with an added seaweed extract.
• 😀 The process includes physical evaluations like pH tests, spreadability tests, and adhesion tests to assess the lotion's quality.
• 😀 The video ends with a demonstration where the creator's friend tests the lotion for safety and performance.

Q & A

What is the main purpose of the video?

The main purpose of the video is to demonstrate how to make body lotion from scratch as part of the creator's final assignment or thesis project.

What are the two main phases of making body lotion?

The two main phases of making body lotion are the oil phase and the water phase, which must be prepared separately and not mixed prematurely.

Why is precise weighing important in making lotion?

Precise weighing is crucial because the percentage of each ingredient directly affects the final result. An incorrect measurement can lead to a failed lotion formula.

What role does the emulsifier play in the lotion-making process?

The emulsifier helps combine the oil phase and the water phase, preventing them from separating. It is key to achieving a smooth, stable lotion.

What challenges did the creator face while making the lotion?

The creator faced challenges in finding the right formula, as well as issues with the water phase being difficult to homogenize and the fear of the formula failing.

Why did the creator decide to make a lotion base first before adding extracts?

The creator made a lotion base first to ensure that the formula worked well before adding the extract. This was done to avoid wasting the extract if the base formula was unsuccessful.

What is the importance of using journals and pharmaceutical handbooks in lotion formulation?

Journals and pharmaceutical handbooks provide valuable knowledge on the ingredients and formulation processes, helping in the creation of a successful lotion recipe.

What heating method did the creator use for the lotion phases, and why?

The creator used a hot plate for heating the phases because it was more convenient. Although a water bath could also be used, the hot plate allowed for more control during the heating process.

Why was it important to stir both phases of the lotion for an extended period?

Stirring the phases for a long time was necessary to achieve a homogeneous mixture. The water phase, in particular, was hard to homogenize and required continuous stirring.

How did the creator ensure the lotion would not freeze during mixing?

The creator ensured the lotion would not freeze by quickly pouring the water phase into the oil phase and stirring immediately. Delaying the process could result in the oil phase freezing, making it difficult to achieve the desired consistency.
