It's not actually a soap. So I don't think making a soap would give you the same product. Here's what I found for the list of ingredients:
VITIS VINIFERA (GRAPE) SEED OIL - TIPA-LAURETH SULFATE - LAURETH-3 - CAPRYLIC/CAPRIC TRIGLYCERIDE - PARFUM/FRAGRANCE - COCAMIDE MEA - PROPYLENE GLYCOL - SORBITAN OLEATE - PRUNUS AMYGDALUS DULCIS (SWEET ALMOND) OIL - CITRUS AURANTIUM BERGAMIA (BERGAMOT) FRUIT OIL - HELIANTHUS ANNUUS (SUNFLOWER) SEED OIL - ROSMARINUS OFFICINALIS (ROSEMARY) LEAF EXTRACT - TOCOPHEROL - AQUA/WATER - LIMONENE - COUMARIN – LINALOOL
So it's more of a chemical product with some detergent type products in it, with some added oils. Not sure how you could imitate it, but it's definitely not a soap product.
