  What is RSSL( relative surface silicone deposition level)

  Posted by Abdullah on January 5, 2025 at 11:11 pm

  I was reading a paper and it was comparing deposition of silicone in hair from this formula

  12% SLES

  2% CAPB

  3% Dimethicone

  0.4% Carbomer 980

  1.5-2% NACL

  0.2% Cationic guar or N-Hance

  4572( a mixture of GHPTC and

  polyAPTAC-ACM)

  All actives

  relative surface silicone

  deposition level (RSSL) from cationic guar was 0.2 and from N-Hance

  4572 it was 2.2

  So what is this RSSL and how much is RSSL 0.2 in ppm or % silicone deposited?

  I’m not familiar with this term but if it’s relative it may be an index range compared to some standard. Can you cite the paper you are reading so we can get more context?

    Here it is.

    It also hase this formula for it

    RSSL = Silicone peak height (Si–CH3) at 796.5 cm–1/

    Hair reference peak area at 940.1 cm–1 to 919.9 cm–1
