Matthew Thomas Farrell
President, Chief Executive Officer & Chairman at Church & Dwight
Good morning, everyone. Thanks for joining us today. I'll begin with a review of the Q1 results. And then I'll turn the call over to Rick Dierker, our CFO. And when Rick is wrapped up, we'll open the call for questions. So Q1 was a solid quarter. Reported revenue was 10.2%. Organic sales grew 5.7% and exceeded our 1% Q1 outlook. Of the 10.2% reported sales growth beat our outlook of 4%, thanks to stronger results from several brands, including Hero, THERABREATH, ARM & HAMMER laundry and ARM & HAMMER litter and exceptionally strong sales growth in our international business. The other good news is that the vitamin business and the WATERPIK business hit their Q1 sales plan, and were right on expectations. And finally, it's also fair to say that we had a degree of conservatism in our original Q1 outlook, both top line and bottom line.
Our Q1 top line growth reflects the strength of our brands, both premium and value and also our focus on execution. The combination of consumer demand and improved case fill, which is now over 93% in the U.S. is resulting in strong revenue growth. Something else that is noteworthy, we had flat volume growth in Q1, which is an encouraging sign after declining volumes in the last six quarters, and we now expect volume growth in our full year net sales outlook. Adjusted EPS was $0.85, which was $0.10 higher than our $0.75 EPS outlook. And that was driven by higher-than-expected sales in the U.S. and especially in our international business, which posted 11.6% organic growth.
In Q1, global online sales as a percentage of total sales was over 16%, and we continue to expect online sales for the full year to be above 16%. Now private label shares remained consistent with historical weighted averages. Both domestic and internationally, private label is stable in our categories. And now I'm going to comment on each business. First up is the U.S. The U.S. consumer business had 5.5% organic sales growth, and eight of our 14 power brands held or gained market share in the quarter. Now I want to look at a few of the important categories in the U.S., and I want to start with laundry. If we look at the big picture, value laundry detergent grew 9%, while premium detergent declined 3%.
So the trade down to value detergent continues into 2023. During Q1, the liquid laundry category grew 3.6%, while ARM & HAMMER grew 9.3%. ARM & HAMMER liquid laundry detergent grew share by 80 basis points in the quarter to 14.3%. So with more consumers migrating to ARM & HAMMER laundry detergent, we have the potential for a long-term benefit to the ARM & HAMMER brand similar to the last recession. Now over in litter, the category grew 12.7%, while ARM & HAMMER litter grew 13.5%. So we gained market share in the quarter. We did see a trade down from our premium ARM & HAMMER Cat Litter to our ARM & HAMMER value litter, which is in the orange box.
So consumers are staying in the ARM & HAMMER franchise. And our Give it the Hammer advertising campaign, which halos met the many categories that ARM & HAMMER competes in is resonating with consumers. Now in dry shampoo, the dry shampoo category was up 11.8% in Q1, driven by BATISTE consumption, which was up 20%. We now enjoy a 46.2% market share in dry shampoo. In the condom category, the condom category was up 4.1% in Q1, while TROJAN consumption was up 5.3%. There again, we gained 80 basis points of market share, thanks to our new TROJAN BARESKIN RAW condom and the success of more targeted marketing. Our most recent acquisitions, THERABREATH mouthwash and Hero are performing extremely well.
THERABREATH, which we acquired in December of 2021, had just a great quarter with 70% consumption growth. THERABREATH grew share 6.8 points to 22.5% of the alcohol-free mouthwash. And as promised when we bought the brand, distribution of THERABREATH has doubled since we acquired it in December of 2021. THERABREATH is now the #2 non-alcohol mouthwash brand and the clear #4 in total mouthwash. We expect this brand to be a long-term grower for Church & Dwight. Now ZICAM, this is a December 2020 acquisition, also delivered strong results this quarter. ZICAM is the #1 brand in the cold shortening segment with a 78% share.
Now to our latest acquisition, Hero, which grew year-over-year consumption by 43.5% and gained 1.6 share points to achieve a 9.1% market share in the total acne treatment category. And distribution has expanded by 50% since the October acquisition date. And as we said in the release, there continues to be a great deal of excitement around Hero -- about the Hero brand and especially the Hero team. From our oldest brand to our recent acquisitions, our brands are driving category growth. I'm going to give you a few examples. ARM & HAMMER liquid laundry detergent, which has a 14% share of the liquid laundry category drove 35% of the category growth.
In the dry shampoo category, BATISTE has a category-leading 46% share, but contributed 75% of the category growth. And in the mouthwash category, THERABREATH makes up 11% of the total category but delivered over 50% of the growth in mouthwash. Next up is international. Our international business delivered organic growth of 11.6% in Q1, driven by strong growth in the subsidiaries and double-digit sales growth from our Global Markets Group, and that was quite balanced across all of our global regions. And the growth was headlined by BATISTE, vitamins, FEMFRESH, WATERPIK and Gravol. And as far as the consumer goes, similar to the United States, unemployment remains low in our international countries where we have subsidiaries.
However, in many of these markets, particularly in Europe, the consumer is facing inflation in energy and food, but so far, consumption has remained strong. In China, while it is a relatively small market for us, we are experiencing stronger growth in Q1 and remain optimistic about the full year apart. And finally, Specialty Products. Specialty Products organic sales decreased 5.9% primarily due to lower volume in the dairy business as low price imports returned to the U.S. market. I want to wrap up my remarks right now by saying consumption is strong. Our value offerings are performing well as are our premium offerings. Acquisitions are on track. We're ramping up our marketing this year in support of our brands and new product launches. And we expect to have the opportunity to invest even more behind our brands in future quarters. And now, I'm going to turn it over to Rick to give you some more color on Q1.
