Emulsifying wax and yellow soft paraffin are the backbone of countless DIY lotions, creams, and ointments. Emulsifying wax binds water and oil into a stable, smooth cream, while yellow soft paraffin adds a protective, occlusive barrier that locks in moisture. Together, they create a rich, spreadable base that is perfect for hand creams, body butters, and balms. This guide walks you through making a simple, effective cream with these two ingredients, explaining the science and offering practical tips for success.
Ingredients
- 3 oz (85 g) emulsifying wax (e.g., Polawax or Ritachol)
- 2 oz (57 g) yellow soft paraffin (also called yellow petrolatum)
- 1/2 cup (120 ml) light oil (such as sweet almond, jojoba, or fractionated coconut oil)
- 1 cup (240 ml) distilled water
- 1/2 tsp (2.5 ml) preservative (e.g., liquid Germall Plus or phenoxyethanol) – optional but recommended
- 5-10 drops essential oil (optional, for fragrance)
Instructions
- Sanitize all your equipment: bowls, spoons, and containers. Wash with hot, soapy water and wipe with rubbing alcohol.
- In a heat-safe glass measuring cup or small saucepan, combine the emulsifying wax and yellow soft paraffin. In another heat-safe cup, measure the distilled water.
- Place both cups in a water bath (a larger pan with 1-2 inches of simmering water) over low heat. Alternatively, use a double boiler. Heat until both the wax mixture and the water reach about 160°F (71°C). Use a thermometer to check.
- Once both are at temperature, slowly pour the water into the oil/wax mixture while stirring continuously with a whisk or a silicone spatula. Keep stirring for 2-3 minutes – the mixture will turn white and thicken as it emulsifies.
- Remove from heat and continue stirring for another minute. If using, add the preservative and essential oil now, stirring well to incorporate.
- Pour the cream into your chosen containers (jars or pump bottles). Let it cool completely at room temperature for about 1 hour, then cover with lids.
- Store in a cool, dark place. The cream will thicken further as it sets.
Tips
- Substitutions: If you don’t have yellow soft paraffin, you can use white soft paraffin or even shea butter, but note that shea butter will change the scent and texture (it will be slightly grainier). Emulsifying wax is not easily substituted – it is the key to the emulsion.
- Storage: Always use a clean, dry spoon to scoop out the cream. Contamination with water or dirt can introduce bacteria. The cream will last 3-4 months at room temperature if you use a preservative; without it, refrigerate and use within 2 weeks.
- Common mistakes: The most common mistake is not heating both phases to the same temperature – if one is cooler, the emulsion can separate. Also, don’t skip the preservative if you plan to keep the cream for more than a couple of weeks; water-based products are prone to mold.
- Texture tweaks: For a thicker balm, increase the paraffin to 3 oz (85 g). For a lighter lotion, reduce the paraffin to 1 oz (28 g) and increase water to 1 1/4 cups (300 ml).
Serving Suggestions
This cream is a versatile base. Use it as a hand cream, foot balm, or body butter. It’s especially effective on dry elbows, knees, and heels. You can also apply it as a protective layer before going out in cold weather, as the paraffin creates a barrier against wind and cold. For a post-shower moisturizer, apply a small amount to damp skin to lock in hydration.
Variations
- Healing Balm: Add 1 tbsp (15 ml) of calendula oil or a few drops of lavender essential oil to soothe irritated skin.
- Whipped Body Butter: After the cream cools but is still soft, whip it with a hand mixer for 2-3 minutes to create a fluffy, mousse-like texture.
- Scented Cream: Use 10-15 drops of your favorite essential oil – like rose, chamomile, or peppermint – to customize the fragrance.
- Ultra-Rich Night Cream: Replace 1 tbsp (15 ml) of the light oil with 1 tbsp (15 ml) of avocado oil or argan oil for extra nourishment.
Storage and Reheating
Store the cream in a cool, dry place away from direct sunlight. It will keep for 3-4 months at room temperature if you used a preservative, or up to 2 weeks in the refrigerator without one. If the cream separates (oil and water split), you can reheat it gently in a double boiler, stirring until smooth, then let it cool again. However, reheating may reduce the effectiveness of the preservative, so it’s best to use it quickly after re-emulsifying. Do not microwave the cream – it can cause hot spots and break the emulsion permanently.
Frequently Asked Questions
Can I use this cream on my face? Yes, but it is quite rich. If you have oily or acne-prone skin, you may prefer a lighter lotion. For dry or mature skin, it works well as a night cream.
Why did my cream separate? Separation happens when the two phases cool too quickly or are not mixed thoroughly. Always heat both phases to the same temperature and stir continuously until the emulsion forms. If it still separates, reheat and whisk more vigorously.
Can I use tap water? Distilled water is best because tap water contains minerals and bacteria that can spoil the cream faster. If you use tap water, boil it first and let it cool to 160°F (71°C) before mixing.
Is yellow soft paraffin the same as petroleum jelly? Yes, yellow soft paraffin is essentially unbleached petroleum jelly. It has a slightly different color and a more natural feel than white petrolatum, but they are interchangeable in most recipes.
How much preservative should I use? Follow the manufacturer’s instructions – typically 0.5-1% of the total weight. For this recipe, about 1/2 tsp (2.5 ml) is correct for a 1-cup batch. If you skip the preservative, refrigerate and use within 2 weeks.
Can I make this without a double boiler? Yes, you can use a microwave, but heat in 30-second bursts, stirring in between, until the wax melts. Be careful not to overheat – the mixture should not exceed 170°F (77°C) to avoid degrading the ingredients.
