Saerohands Making

DIY soap and cosmetic making has a large following in Korea, particularly among buyers who want full control over what goes into their skincare products - choosing specific oils, butters, fragrances, and active ingredients without the preservatives and fillers common in commercial products. The hobby ranges from cold-process soap making (using sodium hydroxide lye and oils) to gentler MP (melt and pour) soap, lotions, toners, face oils, and simple cosmetics.

SAEROHANDS sells the measuring and handling tools that make this formulation process accurate and safe. Precision in soap making is important - incorrect lye-to-oil ratios can produce soap that irritates or burns skin, and thermometer accuracy matters for knowing when to combine ingredients at the right temperature. The tools in this collection cover that need at a price point suitable for home hobbyists.

The glass beakers are heat-resistant borosilicate glass measuring vessels with graduated markings. They are used for measuring liquid oils, water, and dissolved lye solutions during soap making, and for mixing and heating ingredients when formulating lotions or creams. Glass is preferred over plastic for handling lye solutions (sodium hydroxide or potassium hydroxide mixed with water) because lye generates significant heat during dissolution and can warp or degrade some plastics.

The 100ml beaker suits small test batches and precise measurement of fragrance oils, colorants, and additives. The 250ml is the standard working beaker for a typical 300-500g batch of soap or a small lotion batch. The 1000ml is the large-batch beaker suited for making multiple bars of soap at once or for formulating larger volumes of lotion or shampoo.

The PP (polypropylene) plastic beaker at 500ml is suitable for measuring oils, butters, and water in formulations that do not involve lye. PP plastic is more resistant to oils and many cosmetic ingredients than standard plastic, but it should not be used for lye solutions, which require glass. The plastic beaker is a practical addition for a workspace where you are handling room-temperature oils or mixing pre-made cosmetic bases, and it is lighter and less fragile than glass for everyday measuring tasks.

The glass rod is used for hand-stirring ingredients in a beaker, particularly during the initial dissolution of lye into water (where vigorous stirring helps the exothermic reaction complete evenly) and for mixing colorants or fragrance into a soap batter. A 20cm glass rod fits a 250ml or 1000ml beaker comfortably without being too short to use safely. Glass is the preferred material for stirring caustic solutions because it does not react with lye and can be cleaned thoroughly without residue.

Reagent spoons (also called spatulas) are long-handled tools for scooping powders, butters, and solid materials precisely in a lab or formulation context. SAEROHANDS offers two lengths: the 21.6cm Cow Reagent Spoon for standard use, and the 30cm Reagent Spoon for reaching into deeper containers or for working with taller beakers. The longer spoon also reduces the chance of spilling when transferring materials from a container into a narrow beaker opening.

In soap making, reagent spoons are useful for handling sodium hydroxide flakes or pellets when weighing lye - never touch dry lye with bare skin, and use a dedicated stainless steel or glass spoon as lye can degrade some materials over time.

The alcohol glass thermometer measures ingredient temperatures accurately during soap and lotion making. In cold-process soap making, combining the lye solution and oils at the correct temperature range (usually 38-49°C for both, but varies by recipe) is important for getting a good trace without premature saponification. In lotion making, emulsifiers activate at specific temperatures, and combining phases too hot or too cold affects the stability of the emulsion.

An alcohol thermometer reads the temperature of liquids directly, without the need for batteries or calibration. It is a simple, reliable tool for this purpose. Avoid putting the thermometer directly into a lye solution - let it cool enough to handle safely before measuring.

The plastic dropper 3ml (10-piece pack) allows precise measurement of small amounts of fragrance oil, essential oil, vitamin E, or colorant concentrate that would be difficult to pour from a bottle without losing accuracy. At 3ml capacity, each dropper handles one to two standard dropper measurements of a liquid additive. The 10-piece pack provides enough for multiple simultaneous formulations or for single-use handling of particularly concentrated or sensitizing actives.

The mini funnel (10-piece pack) transfers liquids into narrow-necked bottles without spilling - useful when decanting finished lotion or toner into a pump bottle or dropper bottle for storage. The 10-piece count covers a full batch where you might fill several bottles at once.

For a beginner starting with melt-and-pour soap or simple lotion making, the essential tools from this collection are: one 250ml glass beaker for measuring, one 100ml glass beaker for small additives, one glass rod for stirring, one reagent spoon for scooping, the alcohol thermometer, and one pack each of the droppers and mini funnels. For cold-process soap making, add the 1000ml glass beaker for larger oil volumes and a second 250ml or 1000ml for the lye solution.

The plastic PP beaker at 500ml can supplement the glass set for measuring oils at room temperature without risking glass breakage. The total investment in tools from this 24+ item collection covers the core equipment without buying individual items from multiple sources.
