Soap base Crystal SLES & SLS Free, 11.5 kg

Bulk Soap Base Sized for Continuous Production Lines

The Crystal SLES & SLS Free soap base in an 11.5 kg format is built for workshops and manufacturing lines that need a reliable stock of raw material without frequent reordering. This item belongs to the category of Melt and Pour Soap Bases Wholesale, which brings together options suited for conveyor-scale production of clear and translucent soap bars. Because it skips the harsher foaming agents, this base tends to feel gentler on skin, which is why it shows up so often in baby care lines, spa retreat kits, hotel amenity ranges, and gift soap collections sold at scale.

The leading use case for this raw material is, unsurprisingly, clear and decorative soap making, covering embed bars, layered designs, and bars enriched with plant oils or botanical extracts. Soap crafting remains the primary and most in-demand direction for a base like this, though the same material is occasionally repurposed into solid shampoo bars or hand cleansing pucks when the formula keeps the right firmness and lather.

Melting happens around 55-65 degrees Celsius, either on a water bath for small studios or in a temperature-controlled tank for industrial lines. Once fully melted, the mass should cool to roughly 40-45 degrees before any heat-sensitive additive goes in: essential or carrier oils at 1-3 percent of total weight, botanical extracts around 1-5 percent, colorants just a few drops per kilogram, and fragrance oils within a 0.5-2 percent range. Following this sequence keeps active ingredients intact and avoids cloudiness in the finished bar.

Before committing an entire 11.5 kg batch to a new formula, it makes sense to run a trial with the smaller SLS Free Soap Base 500 g, checking compatibility with chosen additives and fine-tuning ratios without risking the larger volume. It's also worth comparing results with the closely related Crystal SLS Free Stephenson Soap Base 1 kg, often used alongside this one to achieve varying clarity levels within a single bar, and with the Soap base Crystal SLES & SLS Free (SS) 1 kg, which differs in firmness and works well for layering.

Common pairings include shea and jojoba oils, glycerin for extra moisture retention, and cosmetic pigments or micas that produce shimmer or gradient effects across a bar. When processing large volumes, keeping the heating uniform matters a lot to prevent localized overheating and discoloration of the mass, and using silicone or polycarbonate molds rated for the melting temperature helps maintain consistent results batch after batch.

Store the base in a dry area at temperatures not exceeding 25 degrees Celsius, away from direct sunlight and heat sources, in its original sealed packaging until use. Under proper storage conditions the material keeps its processing properties for the full shelf life stated by the manufacturer, which matters a great deal when ordering in bulk for a continuous production schedule.

Layered citrus and oat soap bar

Crystal SLES & SLS Free soap base 1000 g

Ground oatmeal 15 g

Sweet almond oil 20 ml

Honey 25 g

Orange essential oil 10 ml

Vitamin E 5 ml

Cut the base into cubes and melt it over a water bath until smooth, avoiding a rolling boil. Once the temperature drops to around 42-45 degrees Celsius, stir in the honey and almond oil until fully blended, then fold in the ground oatmeal so it disperses evenly instead of settling at the bottom of the mold. Add the orange essential oil and vitamin E right before pouring, work quickly to distribute the mixture into prepared molds, and let the bars set at room temperature for several hours until fully hardened.
