Dispersible bath oil with Soya Lysolecithin

Anhydrous oil-to-milk oil with Lysolecithin as the main dispersant.

Save to favourites
An anhydrous, dispersible bath oil for evaluating Soy Lysolecithin as an ingredient that helps the oil phase distribute better on contact with water. The main ingredient is Soy Lysolecithin: although it is not the largest component by weight, it is what enables the emulsion, texture or dispersion to form. This is why the recipe makes sense as a formula specific to this product. Why it is designed this way: - Lysolecithin is used at 15%, a clearly central usage level in an oil-to-milk formula. - The blend of vegetable oil and light ester balances nourishment and rinsing. - It contains no water, so it is not preserved like a classic emulsion, but water must be kept out of the container. - The key test is not pH, but dispersion in water, smell, clarity and the feel after rinsing. Easy level: requires accurate weighing, temperature control when making a hot-process emulsion, and validation of the finished formula. Before scaling up or marketing, check stability, pH where applicable, viscosity, smell, colour, preservation and container compatibility.

Step by step

Prepare the dry equipment 1 Room temperature

Prepare the dry equipment

Clean and disinfect the equipment, but make sure everything is completely dry before starting. In an anhydrous formula, water inside the container is exactly what we want to avoid.

Have a container with a convenient closure ready, as this type of oil is used in small amounts and it is best to avoid putting fingers inside.

Weigh the oils 2 Room temperature

Weigh the oils

Weigh the almond oil, Coco Caprylate/Caprate and jojoba oil in the same beaker.

Mix slowly until the oil phase looks uniform. If any ingredient is very viscous due to the cold, you can gently warm the beaker in a water bath.

Add the Lysolecithin 3 Room temperature

Add the Lysolecithin

Add the Soya Lysolecithin to the oils little by little. Stir patiently, reaching the bottom and sides of the beaker thoroughly.

The mixture may take a few minutes to look completely homogeneous. There is no need for vigorous whisking; the aim is uniformity, not air.

Check dispersion in water 4 Room temperature

Check dispersion in water

Put a few drops of the mixture into a beaker of warm water and stir. It should disperse better than a vegetable oil on its own.

If you are not satisfied with the dispersion, do not adjust blindly: prepare a small test, varying the Lysolecithin in small increments, and compare.

Package and use cautiously Final Room temperature

Package and use cautiously

Package and label with the name and date. As it contains no water, the pH is not adjusted as it would be for a cream or gel.

Use a small amount in the bath or on damp skin, and rinse if desired. Take care, as oils can make the bath or shower slippery.

Preservation, shelf life and validation

  • Indicative anhydrous formula. Work with completely dry utensils and containers; if water enters the container, the risk of deterioration increases.
  • May make the bath or shower slippery. Use a small amount and rinse the surface afterwards.
