刺激の面から好ましくない。2. Description of the Related Art Conventionally, creamy depilatory compositions are produced by emulsifying oil, calcium hydroxide and calcium carbonate and calcium thioglycolate using an emulsifier. . However,
Over a period of about one year, a phenomenon occurs in which fine calcium salts are precipitated and needle-like substances having high hardness are released from the emulsion. Such a phenomenon appears remarkably when the concentration of calcium thioglycolate is 5% by weight or more. Further, these hair removers have the disadvantage that the emulsion stability is significantly reduced, so that the amount of calcium thioglycolate must be reduced. However, when the weight is reduced, it takes a long time to remove the hair, and the commercial value is reduced. It is also conceivable to increase the pH in order to enhance the hair removal performance, but this is not preferable in terms of skin irritation.
