Enzymatically modified lysolecithin is more hydrophilic than conventional lecithin and acts as an O/W (oil-in-water) emulsifier. Lysolecithin is versatile and is considered very pleasant and skin-friendly. Its lipid-replenishing properties—and conditioning effects at a pH of around 5—have also secured it a place in hair care products. In bubble baths or bath oils, it creates an incomparably soft skin feel.  Lysolecithin is easy to work with and tolerates fluctuations in pH. Although it does not withstand prolonged heating at temperatures above 70–80°C, it can be used for hot emulsification; cold-processed emulsions are also possible. In any case, lysolecithin should be used in combination with additional consistency agents, such as butters, waxes, or co-emulsifiers. HLB: 9  Usage concentration: 3–4% in O/W emulsions 0.5–1% as a co-emulsifier up to 10% in bath oils
