Old-Fashioned Rose Soap Recipe
Rose soap recipe featuring rosehip seed oil.
Rose Soap Recipe by Jan Berry. Her new book is called Simple & Natural Soapmaking
This lovely soap features real roses, creamy shea butter and nourishing rosehip seed oil. Rose petal-infused olive oil softens and conditions skin, while coconut oil adds plenty of bubbles and creates a harder bar of soap.
Shea butter is not only great for your skin, but it adds additional hardness to the bar. Rosehip seed oil was included for its fantastic skin-regenerating and healing properties. Rose kaolin clay contributes a natural pink color, but you can use half as much for a paler shade of pink or leave it out completely for a creamy white bar
Rose Soap Recipe Ingredients
- 1 handful fresh or dried rose petals
- 10 oz (283 g) water
- 4.14 oz (117 g) sodium hydroxide (lye)
- 15 oz (425 g) rose petal-infused olive oil (see page 17 for how to infuse oils)
- 1 oz (28 g) rosehip seed oil
- 8 oz (227 g) coconut oil
- 4 oz (113 g) shea butter
- 2 oz (57 g) castor oil
- 2 tsp rose kaolin clay (optional, for color)
- 1 tbsp (15 ml) water
- 1 to 2 tbsp (15 to 30 ml) rose absolute or geranium essential oil (optional)
For the Rose-infused Water
You begin making this rose soap recipe by placing the rose petals in a heatproof jar or container. Heat the water to a simmer and pour over the petals. Allow the rose infusion to steep until it’s room temperature or cooler. Make sure that your tea is fairly light, and not a dark brown color, or it may affect the color of the finished soap. Strain the rose-infused water into a heavy-duty plastic or stainless steel bowl or pitcher.
1. Wearing gloves, goggles and long sleeves, pour the lye into the cooled rose petal infusion and carefully stir until it’s fully dissolved. It may turn a dark brown color as it meets the lye, but that’s okay at this point.
2. Set the lye solution aside for 45 minutes to 1 hour or until cooled to approximately 100 to 110°F (38 to 43°C).
3. While the lye solution cools, weigh the olive, castor and rosehip seed oil and place in your soap mixing pot or container. In a double boiler, heat the coconut oil and shea butter until melted. Pour them into the container with the olive and castor oil. This should bring the temperature to somewhere around 90 to 100°F (32 to 38°C).
4. In a small bowl, stir together the rose kaolin clay, 1 tablespoon (15 ml) water and essential oil until smooth. This will be added at trace* (for cold process soap) or after cook time (for hot process soap).
5. Combine the lye solution and the oils. Hand stir with an immersion blender (powered off) for about 30 seconds, then turn the immersion blender on and mix the soap batter, alternating every 30 seconds or so with hand stirring to prevent the immersion blender’s motor from burning out. Continue mixing until trace is reached. This recipe will reach trace within a few minutes.
6a. For Cold Process Soap
Thoroughly stir the clay, water and essential oil mixture into the soap. Pour the soap batter into a prepared soap mold, cover with a sheet of wax paper and then the mold’s lid or a piece of cardboard. Tuck a towel or quilt around the mold to help hold the heat in. Let the soap stay in the mold for 24 to 48 hours, then remove and slice into bars. Allow the bars to cure in the open air for at least four weeks before using.
6b. For Hot Process Soap
Pour the soap batter into a slow cooker turned on low heat. Cover with the lid and let cook for 1 hour, checking and stirring every 15 minutes. After the hour has passed, stir in the clay, water and essential oil mixture, then spoon the cooked soap into a prepared mold. Allow it to firm up overnight, then remove from the mold and slice into bars. You can use hot process soap right away, though it makes a longer-lasting bar if it cures in the open air for a few weeks.
* “Trace” means that the soap batter is thick enough to leave a faint, fleeting imprint when it’s drizzled across itself.
