Make and email address lowercase

So I'm trying to create a lower case version of an email however, I'm wondering if culture will have an affect.

public class aspnet_Membership
{  
    //...
    public Email { get; set; }
    public LoweredEmail { get; set; }
}

Currently I'm just calling .ToLower() like so:

this._user.aspnet_Membership.Email = value;
this._user.aspnet_Membership.LoweredEmail = value?.ToLower();

I know there are casing issues in some languages, I haven't investigated the emca spec for email addresses. Is this safe to do, or do I need to use CultureInvariant or will there always be cases where domain names will transform wrong etc?

You can use the following approach for making lowercase all the letters of each word by using CultureInvariant :

text = string.IsNullOrEmpty(text) ? string.Empty : 
    text.ToLower(new CultureInfo("en-US", false));
