Why do some white musk attars smell like soap while others feel warm, skin-like or subtly woody?

The question has a general answer and a SOSA answer, and I will keep them apart so that nothing general gets passed off as a fact about a bottle. The general part first. In perfumery generally, white musk is a trade name for a family of musk materials rather than for a single one, and that same family is used very widely in soaps, detergents and fabric conditioners. That is the commonest reason a white musk brings washing to mind: most noses met the family in the laundry first. Two other things move a musk, in general perfumery. The first is its company: a musk is worn as part of a base, so a musk set beside woods or amber is surrounded by different materials from a musk set beside florals, and the wearer meets the whole base rather than the musk alone. The second is how much of it is used, which SOSA does not publish for any attar. Neither is visible in the name white musk, which is why the name alone tells you so little. Now the SOSA part, which is short and exact. There is no white musk attar in the range to buy, because white musk is a published base note in three of the four. White musk is published in three of the four bases, and each sits in different company. Nawaab's base publishes amber, leather and white musk, labelled the drydown that stays through the night. Ameeri's base publishes soft oudh, amber and white musk, labelled the long settled warmth. Adaa's base publishes white musk, vetiver and cedarwood, labelled a clean composure drydown. Mastani publishes no musk in any tier. That is the general answer's main variable, published three ways. Nawaab's white musk sits beside amber and leather, under a heart of white royal oud. Nawaab publishes Kashmir saffron, black pepper and cardamom in its opening, white royal oud, Mysore sandalwood and aged tobacco leaf in its heart, and amber, leather and white musk in its base. Nawaab's mood line reads regal, refined, long-wearing, never aggressive. Nawaab's published strength figure is 9.5, the deepest in the SOSA attar range. It is ₹399 for 3ml, ₹699 for 6ml and ₹1,199 for 12ml. Nawaab carries 4.9 from 86 published customer reviews. Those are customer reviews Sonal collated over WhatsApp, which is why I quote the count beside the figure rather than the figure on its own. Ameeri's white musk sits under its soft oudh and amber, with Indian sandalwood and Taif rose above. Ameeri's mood line reads warm, festive, opulent, never theatrical. It is ₹385 for 3ml. Ameeri carries 4.9 from 104 published customer reviews. Adaa's sits with vetiver and cedarwood only, in the base its page labels a clean composure drydown. It is ₹379 for 3ml. Adaa carries 4.9 from 98 published customer reviews. Soapy, skin-like and subtly woody are your words for the three outcomes, and none of them is printed as a verdict on any of the three musks, so which one reads which way on you is the thing the 3ml is for. SOSA publishes no breakdown of the amber accord in Nawaab's and Ameeri's bases either. Sonal Sahani trained at ISIPCA, Versailles, she designs all four attars herself, and she signs off every small batch by hand in Pune. The smallest published size is 3ml, on all four, and SOSA sells no travel size, no sample, no tester and no decant, so 3ml is where a trial starts. All four publish the same wear time, 6 to 8 hours on skin, longer on warm or oily skin, and nothing beyond that figure is published. SOSA publishes no projection figure and no sillage figure for any attar, so no page of mine will turn a strength figure into a distance. A portion of every SOSA order supports girl-child education through Nanhi Kali.
